All of this has pointed to one conclusion, Triceratops and Torosaurus (and also Nedoceratops) are all one species in different growth stages, Triceratops is the sub-adult, Nedoceratops is the transitional form, and Torosaurus is the adult. It’s not unprecedented for scientists to determine that what were previously classified as distinct dinosaurs were actually just different life stages of the same species. Scannella said he presented his and Horner's findings at the 2009 Society of Vertebrate Paleontology Conference in Bristol, England, and it was met with equal parts intrigue and skepticism. The following information on the origin and facts regarding Triceratops precisely sum up all features and characteristics typical to this category of frill-necked saurians. 5G and future 6G terahertz absorbed by water vapour = heating? Bye bye 'Hogwarts dinosaur'? New analyses of dinosaur growth may wipe out one-third of species, Chinese photonic quantum computer demonstrates quantum supremacy, Researchers observe what could be the first hints of dark bosons, Nanoparticle jamming at the water-oil interface. Triceratops! Among the larger ceratopsians, Torosaurus is similar in size and appearance to its relative, Triceratops. Torosaurus was approximately 25 feet long, 8 feet tall at the hips and probably weighed around 8 tons. Recent research suggests that the contemporaneous Torosaurus, a ceratopsid long regarded as a separate genus, actually represents Triceratops in its mature form. Two years later, Marsh named Torosaurus… Scannella said he and Horner tried for three years to look for alternative explanations for their findings. Torosaurus is characterized by an elongate frill with a straighter edge, a concave squamosal, and lack of upturning of the frill. You can unsubscribe at any time and we'll never share your details to third parties. Over the past couple of years, Scannella and Horner traveled to museums across the country to examine more than a hundred Triceratops and Torosaurus specimens. and Terms of Use. Even in Triceratops that were previously considered to be adults, the skull was still undergoing dramatic changes. "If so, Triceratops may have a lot to teach us about biodiversity and extinction today," Scannella said. "Torosaurus" specimens are much rarer than Triceratops, however. "It is possible that mortality was fairly high for Triceratops before they reached their fully mature morphology.". : 31 A new study shows that the Triceratops and the Torosaurus may have been the same dinosaur, because their frills keep growing with age. Triceratops is characterized by a short frill with a flat squamosal, an upturned caudal margin of the frill, the absence of fenestrae, and a midline epiparietal. part may be reproduced without the written permission. Although Scannella and Horner, his advisor, agreed that these dinosaurs might be the same species, they thought the differences between Triceratops and Torosaurus were more likely the result of age than sex. In the Late Cretaceous, herds of horned herbivores like these were very common…and attracted many predators. But if similar dinosaur species turn out instead to be babies, teenagers and adults of the same species, then the kinds of ecological questions scientists ask will be different, he says. Triceratops (left) had a shorter frill than Torosaurus (right). Medical Xpress covers all medical research advances and health news, Tech Xplore covers the latest engineering, electronics and technology advances, Science X Network offers the most comprehensive sci-tech news coverage on the web. Torosaurus had giant holes in its frill. If an area was once home to several species of very closely related animals, then scientists need to think about how the animals could have co-existed, in terms of sharing available food resources, for example. The case that the dinosaurs we have called Torosaurus are simply fully mature Triceratops relies on the hypothesis that we are not going to find juvenile, sub-adult or young adult Torosaurus. "But so far, all the evidence we have strongly supports the idea.". None of the Torosaurus specimens came from immature animals, Scannella said. About 20 years ago, paleontologists John Ostrom of Yale University in New Haven, Conn., and Peter Wellnhofer of the Bavarian State Collection for Paleontology and Geology in Munich, Germany, first suggested Triceratops and Torosaurus might be members of the same species, Scannella says, with Torosaurus, the larger animal, actually being a male Triceratops and the smaller Triceratops being females. Triceratops had a three-horned skull with a rather short frill, whereas Torosaurus had a much bigger frill with two large holes through it. Both horned dinosaurs had a giant bony frill that rose up behind the head, but Torosaurus’ frill was much longer and was adorned with giant holes that were covered by a thin layer of protein called keratin. Peter Dodson, a paleontologist at the University of Pennsylvania in Philadelphia, Jack Horner of Montana State University in Bozeman, reported in PLoS ONE that two genera of dome-headed dinosaurs —, John Scannella, a doctoral student at Montana State University, published in the Journal of Vertebrate Paleontology, An adult cassowary, for example, has a large bony crest on its head. Such misclassifications have happened because scientists haven’t always considered growth patterns and development when assessing dinosaurs, so it’s likely there are many more cases of mistaken identity out there, says John Scannella, a doctoral student at Montana State University and co-author of the new study, published in the Journal of Vertebrate Paleontology. : 21 The skull of the Torosaurus was the largest of any land animal ever found. Finally, the work reminds us that paleontologists are far from knowing all there is to know about even the most iconic dinosaurs, Scannella says. MSU paleontologists John Scannella and Jack Horner said in the July 14 issue of the Journal of Vertebrate Paleontology, however, that Triceratops and Torosaurus are actually the same dinosaur at different stages of growth. Both horned dinosaurs had a giant bony frill that rose up behind the head, but Torosaurus ’ frill was much longer and was adorned with giant holes that were covered by a thin layer of protein called keratin.

Triceratops and its cousin Torosaurus are not hard to tell apart. Searching for sub-eV sterile neutrinos using two highly sensitive detectors. This was explained by the assumption that the number of epoccipitals increased during maturation. The finding that Torosaurus was a grown-up Triceratops adds fuel to the theory that dinosaur diversity at the end of the Cretaceous Period and Mesozoic Era was far less than previously thought, Scannella said. But since Triceratops was named the first out of these three the genus will still be named Triceratops. After comparing the skull shape of the triceratops to that of its close relative, the torosaurus, researchers John Scannella and Jack Horner concluded that the triceratops may actually be a juvenile form of the torosaurus (not an entirely different species), as dinosaurs' skulls could change shapes during their lifetime. triceratops vs Torosaurus If this is true, then it means Triceratops didn’t gain some of its adult traits — the longer frill and holes — until very late in development, as none of the largest (and presumably oldest) Triceratops possess the defining traits of Torosaurus. © 2008-2020. All of this evidence points to Torosaurus being an adult Triceratops, Scannella says. When the paleontologists did find "Torosaurus" skulls, the skulls were all large. Get weekly and/or daily updates delivered to your inbox. Andrew Farke, curator of paleontology at the Raymond M. Alf Museum of Paleontology in Claremont, Calif., also finds it hard to believe that Triceratops and Torosaurus were the same animal. This document is subject to copyright. Your feedback will go directly to Science X editors. Click here for all copyright requests. Many undergraduate students, as well as volunteers from around the world, participated in the project by discovering and excavating the Triceratopsspecimens in the field. The Colorado Rocky’s mascot is … Also the number of episquamosals on the side edge of the frill differs: five with Triceratops, six or seven with Torosaurus. Older individuals have more bone remodeling, in which older bone is replaced with new bone, so older bone looks different than younger bone. You can be assured our editors closely monitor every feedback sent and will take appropriate actions. Yet Triceratops and Torosaurus may have been more alike than scientists realized: New research suggests that the two animals were actually the same species, with Torosaurus being the adult version of Triceratops. Both existed around the same time, i.e., the latter part of the Cretaceous Period. The Triceratops study suggests that it is critical that paleontologists consider ontogeny (growth from a juvenile to an adult) as a source of major morphological variations before naming new species of dinosaurs to account for variation between specimens, Scannella added. or, by Montana State University. The confusion over Triceratops and Torosaurus was easy to understand, Scannella said, because juvenile dinosaurs weren't just miniature versions of adults. This work provides further evidence of that decline, Scannella says, and forces scientists to consider what caused dinosaurs to dwindle at this time. (credit: CBS) More of us may know about the triceratops. "Triceratops (Three-Horned Face) is one of the most recognizable non-avian dinosaurs. Torosaurus has a large bulky body, a wide, sweeping frill, and … If Torosaurus and Triceratops are the same species, then the significance of the change goes beyond the need to update textbooks and museum exhibits, Scannella says. "We have to put together the story based on fossils. googletag.cmd.push(function() { googletag.display('div-gpt-ad-1449240174198-2'); }); Since the late 1800s, scientists have believed that Triceratops and Torosaurus were two different types of dinosaurs. From CalAcademy and the University of California Museum of Paleontology, a great introduction on how the Triceratops (named in 1889) and the Torosaurus (named in 1891) are actually the same dinosaur at different stages of life. That would make Horner and Scannella’s case even stronger, he says. In the 1970s, Peter Dodson, a paleontologist at the University of Pennsylvania in Philadelphia, demonstrated this with duck-billed dinosaurs. Do equations for groundwater flow refer to water density? Thus, being one of T. rex's principle favorite prey, Torosaurus was close to the bottom of the f… It had a very large skull that was in excess of 8 feet long and had a bony frill behind the back of the skull. Thank you for taking your time to send in your valued opinion to Science X editors. It very much resembled its cousin Triceratops, but had a much longer frill, with two large holes (or fenestrae).In 2009 researchers under supervision of Jack Horner argued that Torosaurus was the oldest form of Triceratops. T. Rexes lived in the upper Cretaceous Period, around 67 to 65.5 million years ago. All rights reserved. "Every avenue of investigation we took in attempts to falsify the hypothesis only supported the idea further," Scannella said. In recent years, in part due to the number of dinosaur species that have been consolidated because of misclassifications, paleontologists have noticed that dinosaur diversity started to decline during the Late Cretaceous, just prior to the asteroid impact 65.5 million years ago that killed off the dinosaurs. Your opinions are important to us. Forty percent of the specimens came from Triceratops at different stages of growth. : 11 The large frill of the Torosaurus was very thin. (PhysOrg.com) -- Research by a Montana State University doctoral student and one of the nation's top paleontologists is upending more than 100 years of thought regarding the dinosaurs known as Triceratops and Torosaurus. Neither your address nor the recipient's address will be used for any other purpose. Some of the skulls belonged to juvenile Triceratops and roughly the size of footballs. If the apparent decline in diversity wasn't triggered by a meteor -- a relatively uncommon event -- Scannella said, "It may have been caused by circumstances which are more likely to affect diversity today, perhaps large-scale sea level fluctuations or climate change. Scannella and Horner examined more than 50 Triceratops specimens for their study. Other skulls are the size of a small car. Torosaurus is a ceratopsid genus first identified from a pair of skulls in 1891, two years after the identification of Triceratops. He says he’s not “unconvincible,” but needs to see much more data before he would be sold on the idea. More than 30 were skulls that came out of the Hell Creek Formation and are housed at the Museum of the Rockies. “I just have a hard time swallowing that the transformation would be that great.” He also points out that the fusion of sutures on Triceratops skulls suggest that some of the largest-known Triceratops were indeed fully grown, because such sutures don’t fuse until later in life in animals. Torosaurus. Andrew Farke, curator of paleontology at the Raymond M. Alf Museum of Paleontology in Claremont, Calif. Michael Ryan, curator of vertebrate paleontology at the Cleveland Museum of Natural History in Ohio, After hurricanes, U.S. beach homes are rebuilt bigger, Geoethics in the Field: Leading by Example, Inside the inferno: How large firenadoes form, Wind or water? The Journal of Vertebrate Paleontology is the official journal of the Society of Vertebrate Paleontology. One problem with the idea, he says, relates to the dinosaurs’ epoccipitals, projections of bone that line the edges of the animals’ frills. Such late blooming is not unheard of in the animal kingdom, Scannella says. With Triceratops there are typically five epiparietals, including a midline osteoderm; with Torosaurus there are ten or twelve, a midline epiparietal being absent. Triceratops are extremely tenacious and aggressive in temperament. They found that Torosaurus skulls followed growth patterns distinct from Triceratops skulls. They looked very different, and their skulls changed radically as they matured. "By studying patterns of diversity in the past, we attain insights into current ecological trends.". The pair cut samples from the horns of several Triceratops and Torosaurus specimens, and noticed the Torosaurus skulls had more bone remodeling than the most mature Triceratops samples, indicating a more advanced age for the Torosaurus specimens.

"Without considering changes in shape throughout ontogeny, we overestimate dinosaur diversity and hence produce an unrealistic view of the paleoecology of these animals," Scannella said. When the animal was alive, the holes were covered in a thin layer of keratin. Triceratops did not have holes in its frill. Specimens have been observed surviving with their horns, tails and even snouts partially bitten off. Hurricane Harvey's most destructive force. But no one had studied that possibility until now. Your email address is used only to let the recipient know who sent the email. "A major decline in diversity may have put the dinosaurs in a vulnerable state at the time when the large meteor struck the Earth at the end of the Cretaceous Period," Scannella said. The genus Torosaurus resembles Triceratops in geological age, distribution, anatomy and size and it has been recognised as a close relative. Torosaurus, very rare during the Lancian Age of the Cretaceous, retains that basic design: the frill is composed of thin bone rods that make a frame, with huge holes in the middle. Level Fact 1 The name Torosaurus, "bull reptile", was inspired by the skull and the two very long and robust brow horns. Study finds Triceratops, Torosaurus were different stages of one dinosaur by Montana State University The classic image of a Triceratops is on the left. Still, Farke says, several characteristics of Triceratops are unusual compared to other horned dinosaurs, so anything’s possible. For example, the horns of a young Triceratops pointed backward; as the animal matured, its horns started to face forward. General Statistics Edit. They added that the discovery contributes to an unfolding theory that dinosaur diversity was extremely depleted at the end of the dinosaur age. Both lived around between 66.8 and 65.5 million years ago. Triceratops lived in the Late Cretaceous period, around 68 to 65.5 million years ago. Triceratops is the commonest horned dino of the time, the final dinosaurian Age, the Lancian. They finally agreed that the Triceratops and Torosaurus were the same dinosaur. By Olivia Solon, Wired UK A newly discovered horned dinosaur called Titanoceratops appears to have reigned long before its more famous descendants, Triceratops and Torosaurus. Microscope studies revealed that the tissues of Torosaurus specimens are more heavily remodeled than those of even the largest Triceratops, strongly suggesting that Torosaurus specimens are in fact adult Triceratops, Scannella said. "Torosaurus is a distinct and valid taxon. These animals inhabit stretches of open prairies or marshlands in small herds, where they feed on ferns and woody shrubs. It was on the menu for Tyrannosaurus rex. The history of the Triceratops dinosaur is similar to the Torosaurus. As part of the study, field crews collected hundreds of specimens. An adult cassowary, for example, has a large bony crest on its head that develops suddenly at the end of the bird’s adolescence, he says. The first, named Triceratops in 1889, had three impressive horns jutting out of its face and a solid, curved frill. Triceratops had many more epoccipitals than Torosaurus, he says, so the new hypothesis would imply that as a Triceratops grew up, it lost some of its epoccipitals — that would be “unprecedented” among horned dinosaurs. Scannella is a doctoral student in earth sciences, and Horner is Regents Professor of Paleontology at MSU's Museum of the Rockies. Its name means "perforated lizard", although often incorrectly interpreted as "bull lizard". “It’s a very creative hypothesis and they’ve got interesting data in support of it,” Dodson says. Led by Horner, the large-scale project was conducted to reconstruct the ecosystems that existed during the Cretaceous Period that ended about 65 million years ago when there was a mass extinction of dinosaurs. However, It had one of the largest skulls of any land animal known in comparison to its body, reaching 3 meters (10 ft) in length. Hobbled by its puny arms, T. Rex requires a few precious seconds to lever itself off the ground — by which time Triceratops has lumbered up on … T’tops departs from the ceratopsian tradition of frill construction. Daniel Hendricks, Creative Commons Attribution-ShareAlike 2.0 Generic. All species of horned dinosaurs had epoccipitals and the number stayed the same throughout an animal’s life.

These were the magnificent cattle of the Cretaceous period. “Even a dinosaur like Triceratops, which we’ve known about for 120 years, still has surprises in store for us and a lot to teach us about the history of life on this planet.”. "Skepticism is important and a good thing," Scannella commented. Some scientists (starting in 2010) consider Torosaurus fossils to simply represent mature Triceratops after their frills had extended, but later research (2011 and 2012) seems to prove otherwise. We do not guarantee individual replies due to extremely high volume of correspondence. They grouped the Triceratops skulls in their sample into different life stages based on certain features that scientists had previously determined changed as the animal got older. By studying the Torosaurus skulls, they also learned that Torosaurus had all the known signs of a mature Triceratops, such as forward-facing horns. The paleontologists also examined skulls from several North American institutions, including the American Museum of Natural History in New York, the National Museum of Natural History at the Smithsonian Institution in Washington, D.C., and the Peabody Museum of Natural History at Yale University in New Haven, Conn. Scannella and Horner measured the length, width and thickness of the skulls. One valuable piece of data would be the discovery of a skull that exhibits transitional features between Triceratops and Torosaurus, says Michael Ryan, curator of vertebrate paleontology at the Cleveland Museum of Natural History in Ohio. It also changes the way scientists view dinosaur ecology, Scannella adds. “I think [they’re] probably correct … but we need more data.”. Recent studies have revealed extreme changes in the skulls of pachycephalosaurs, tyrannosaurs and other dinosaurs that died out about 65 million years ago in North America. A study has rejected claims that Triceratops and the lesser-known Torosaurus are one and the same type of dinosaur. Last year, paleontologists Jack Horner of Montana State University in Bozeman and Mark Goodwin of the University of California at Berkeley reported in PLoS ONE that two genera of dome-headed dinosaurs — Dracorex and Stygimoloch — were really just young members of Pachycephalosaurus. Artwork by Holly Woodwrad, Montana State University. Triceratops has been documented by numerous remains collected since the genus was first described in 1889, including at least one complete individual skeleton. They were two of the last species of dinosaurs to exist before mass extinction. This dinosaur also had a toothless beak and a large, heavy body like a triceratops. Three species have been named, Torosaurus latus, T. gladius, and T. utahensis. Apart from any fair dealing for the purpose of private study or research, no Some undergraduates also helped prepare the fossils once they were brought back to the Museum of the Rockies. Researchers have long recognized similarities between Torosaurus and Triceratops, the main distinctions being that Torosaurus is larger and … Abi Howe, American Geological Institute/ESW Image Bank. In looking at differences between the age groups, Scannella and Horner found that as a Triceratops aged, its frill elongated (approaching the length of Torosaurus) and the bone thinned out — specifically, the bone got thinner in the precise areas where Torosaurus had its holes. "Paleontologists are at a disadvantage because we can't go out into the field and observe a living Triceratops grow up from a baby to an adult," Scannella said. "It may have been the combination of the two factors -- lower diversity and a major global catastrophe -- that resulted in the extinction of all the non-avian dinosaurs.". They further tested their idea by looking at the bones’ microstructure under the microscope. The content is provided for information purposes only. Scannella and Horner benefited from an extensive 10-year study of the Hell Creek Formation in Eastern Montana. NAD: Is nicotinamide adenine dinucleotide a super supplement or all hype? Torosaurus was a large ceratopsid dinosaur. Click here to sign in with On the top, a Triceratops skull characterized by a short frill without holes. Like the triceratops and torosaurus, the dracorex was once thought to be a separate species from the more well-known pachycephalosaurus, the dome-headed dinosaur seen in The Lost World: Jurassic Park. And that opening is the definitive difference between a triceratops and a torosaurus. Torosaurus also lacked the long nose horn seen in Triceratops prorsus, and instead resembled the earlier and more basal Triceratops horridus in having a short nose horn. "If Torosaurus is actually the mature form of Triceratops, we must ask why ‛Torosaurus' specimens are relatively rare compared to Triceratops," Scannella said. Triceratops and its cousin Torosauru s are not hard to tell apart. On the right is the new face of Triceratops… Dinosaur King Statistics Name: Torosaurus latus.
