A University of Kansas research team recently unearthed a fossilized upper jaw with perfectly intact teeth in the Hell Creek Formation of Montana. While tests still need to be performed to confirm its nature, it is small and has a frightening resemblance to larger Tyrannosaurus Rex fossils, suggesting that the old teeth were from a child about 66.5 million years ago
The goal at the moment is to confirm that it is indeed a baby T. rex because there is still a chance that it will be a species could be a small carnivore. Only a handful of T. rex fossils have ever been found. Therefore, KU paleontologists are working to bring them into line with those and some of the adult fossils that are more common.
But since all animal skeletons change with age, this is no easy task. Other fossils have been found in the area and classified as a kind of "Nanotyrannus", but some paleontologists believe that these are also young Tyrannosaurs rex fossils.
Once confirmed, this set of once-razor-sharp teeth can reveal much about the lifecycle of the king of dinosaurs (or at least, dinosaurs in the Cretaceous). According to David Burnham of the KU Biodiversity Institute, it's difficult just because a young T. rex is so hard to come by. He said the following in a Kansas University press release:
"Teeth indicate that it is a Tyrannosaurus Rex, but there is more to be done because a young T. rex is so rare There are few that have been found over the years that make it difficult to see what changes are due to growth, or whether the differences in bones reflect different species. "Fortunately, KU has an older T. rex for comparison with another Boys T. rex borrowed to decipher this problem. "
Young dinosaurs can still be a challenge as these types of fossils still exist harder to get than the normal adult. Histories such as Jurassic Park have attempted to show how dinosaurs look like, as well as fewer scientific films such as The Land Before Time but there is always an artistic license.
This fossil could help the next Jurassic World film be more accurate, though it's hard to imagine that the studio cares about it anyway.
