First Tyrannosaur Embryo Fossils Revealed

Paleontologists have made a great discovery that has uncovered the truth about Tyrannosaurus dinosaurs during a time when they are in the embryo and childhood. A claw and jaw have been found in the embryonic stage of these reptiles. These fossils were found at different times but near the same archaeological spots. The claw was discovered in 2018 and the jaw was uncovered in 1983. Both fall into the prime area for Tyrannosaurs, about 70 to 75 million years ago.

The skeletons were put into a 3D simulation to see how big these creatures were. It was concluded that they were around three feet long. Scientists determined that the bones could grow into the grownup versions of the dinosaurs, just like how babies grow into adults. Fully matured ones were usually around thirty feet long, which is hard to believe when embryos started off at 17 inches long. Other kinds of skeletons were also found in the nesting area which indicates infant Tyrannosaurus and other ages feeding on those diverse reptilians.  Little ones have been thought to have eaten lizards and insects until they were large enough to feast on bigger animals. 

Information on embryonic tyrannosaurus has never been completely concluded, making this finding even more exciting for scientists. Most fossils found for this dinosaur are at the middle to a late stage in its life cycle. Now, paleontologists know these reptiles have nesting grounds and did not continually travel for breeding areas. Researchers will now be able to ask fresh questions and, hopefully, answer some that have puzzled scientists.
