What we thought we knew about T rex was wrong, researchers say in new study
Fox News
A new fossil study is casting doubt on long-held beliefs that smaller versions of the Tyrannosaurs rex were adolescent versions of their famous adult counterparts.
The study, which was published in the journal of Fossil Studies, researched the growth rings of young T. rex fossils and found evidence that bone growth rates were slowing and indicated that the Nanotyrannus versions of the famous dinosaurs were likely almost full size.
"If they were young T. rex they should be growing like crazy, putting on hundreds of kilograms a year, but we're not seeing that," Dr. Nick Longrich, co-author of the study, said in a report published by New Atlas. "We tried modeling the data in a lot of different ways and we kept getting low growth rates."
