Everything you need to know about the scientific controversy that could change Triceratops forever

If you cry over the gruesome Triceratops in Jurassic Park , or just loved this tusk dinosaur as a nestling , there ’s one scientific controversy you need to understand mightily now — it may wind up demonstrating that Triceratops is n’t who we guess it was . Recently unearthed grounds has sparked a Modern public debate over the identity of several ceratopsid dinosaurs , including our beloved Tri , who many paleontologist believe is simply the young translation of a animal called Torosaurus . But if a Triceratops is just a young Torosaurus , is Nedoceratops what comes in between ? Or are they actually three dissimilar species ? Here ’s everything you require to be intimate to take a stand on this controversy .

Classifying dinosaurs is difficult under the best circumstances . With the ceratopsids , condition are not ideal . uncomplete specimen , damaged bones and little sampling sizes plague research worker . For example , it would be a muckle easier to assign an age to Torosaurus skulls if we had some complete underframe to go with them . Worse , many specimens have been restore wrong , making their morphology appear misleading . The worst case scenario is when there ’s only a single specimen for an intact genera , make it unsufferable to know if it really is a separate brute , a variation in the geomorphology of other animals , or an aberration due to disease or trauma .

The ceratopsid controversy depart with two interchangeable brute , Triceratops ( of three saddle horn and a substantial skull frill ) and Torosaurus ( of three saddle horn and large perforations , or fenestrae , in the skull trumpery ) . Paleontologists have found quite a few Triceratops skulls , but only a half - XII Torosaurus skull . Then there ’s Nedoceratops . There ’s only one live example of a Nedoceratops ( which you may visit at the Smithsonian Museum of Natural History ) , and there ’s some evidence that the specimen might be unnatural – there are some assymetric bone densities in the skull , and the fenestrae appear irregular — Torosaurus ’ fenestra are orotund and quite steady in shape .

The sorting of ceratopsids is kind of a tidy sum . When the first specimens were regain , paleontologists assigned a new genera or species to pretty much every horned skull that look a little different from the other horned skulls . There were 16 different species of Triceratops at one detail . There ’s been a trend in the last decade or so to try and consolidate some of those genus and coinage . Linking antecedently separate genera would change what we know about biodiversity in the recent Cretaceous and remold our idea about ceratopsid evolution .

Here are the main viewpoints on the subject field , summarized :

Triceratops and Torosaurus are the same animal . In 2010 , a study suggested that Torosaurus is really the adult version of Triceratops . Wereported on that study when it came out , and at the time it made a lot of sense . The two dinosaurs are pretty similar , and loss of bone material is certainly something that can pass off to an animal as it age . There ’s even common law for it among other dinosaurs . Sauropods ( huge , long - necked herbivores like Apatosaurus ) sometimes have ivory formations in their pelt known as osteoderms . The discovery of hollow osteoderms near mature specimens suggest the bone stuff may have been reabsorbed during thin years to offer a steady supplying of all important minerals . Torosaurus has a monumental skull , so it ’s possible that as it aged , Triceratops reabsorbed the bone and developed fenestrae to boil down the weight of its enlarging furbelow . Also contribute credence to the theory : the geographic dispersion of both genus overlap well .

Nedoceratops is the same animal as Triceratops and Torosaurus . John B. Scannella and John R. Horner of Montana State University released a study that concludes Nedoceratops is an intermediary footfall in the transition from young Triceratops to old Torosaurus . Although the holotype ( the only known specimen , or the formally recognized exemplar ) for Nedoceratops does n’t look much like your average Triceratops at first glimpse , Scannella and Horner looked at all the examples we have of Triceratops and found some that are fairly close to what Nedoceratops looks like . Nedoceratops is missing that nose cornet , but lots of Triceratops had really small nozzle horns , so it might just be within the kitchen range of expected magnetic declination , or the nose horn might have been lost to injury . On top of that , the Nedoceratops holotype ’s fenestra are smaller than Torosaurus ’ , suggesting they are in the process of develop into the large fenestrae of Torosaurus . Scannella and Horner also found cutting in the frills of some Triceratops skulls in the same country as the fenestrae . As for the difference in horn slant , it might be individual variation , or the orbital horn might switch with years .

Nedoceratops is a separate genus or an abnormal Triceratops . Andrew A. Farke ( Raymond M. Alf Museum of Paleontology ) disputed Scannella and Horner ’s claim , note that the single specimen of Nedoceratops just does n’t give us much to go on . It ’s been partly reconstructed with plaster , so it ’s hard to tell apart if it would have fenestrae on both face of the frill . A lot of Farke ’s work is based on bone texture , which is used to estimate the years of the dinosaur when it died . harmonise to his analysis , the exist Nedoceratops looks like a ripe animal – it ’s unlikely it would “ grow up ” to be a Torosaurus because it ’s already grown up .

Triceratops and Torosaurus are not the same animate being . The most recent written report , by Nicholas R. Longrich and Daniel J. Field of Yale ’s Department of Geology and Geophysics , attempts to disassemble the Triceratops / Torosaurus theory . Their analysis intimate that Triceratops and Torosaurus specimens show a range of ages , with some possile immature Torosaurus specimen , and a wide range of sizing and maturity among Triceratops specimens . As for Nedoceratops , Longrich and Field rebate it as , “ clearly pathological … the opening in the parietal is also unpredictable in shape , which strongly advise that it is the outcome of injury or disease , and not a natural lineament . ” They conclude that all three ceratopsians most in all likelihood belong to dissimilar genera .

The nerveless thing about the whole debate is how it shows off science in action . Everyone on all sides concord that there are some things we ca n’t know for certain due to insufficient grounds . Until we find some more Nedoceratops specimens , more all over Torosaurus specimens , or find some other way to conclusively link ( or unlink ) the specimens we have , the debate will keep on . It ’s an true friendly argumentation , with paleontologist geeking out over their shared passion of dinosaur . We ’ve also already learned a lot from the debate – the fact that dinosaurs ’ syllable structure could change drastically over the course of a lifespan has been placed under focus , and could seriously interchange how we look at dinosaur we fuck and new one we have n’t discovered yet .

This is also a really sound good example of open seed science . All of the studies mentioned in this clause are available to be take in full , for free , at PloS One ( see the sources list ) . Andrew Farke ( who writesa blog about open root paleontology ) even put all his subject area observe online under a Creative Commons license , so youcan see his cartoon and measurementsof various specimen .
