This is what baby tyrannosaurs would have looked like when they hatched - New York Post

Baby tyrannosaurs were just about the size of Border Collies when they took their first steps — despite being able to grow up to 40 feet, according to a study published Monday.

Their findings suggest that the meat-eating creatures — cousins of the T-Rex dinosaurs who lived more than 70 million years ago — were only about 3 feet long when they hatched

His team also estimated that tyrannosaur eggs would have been about 17 inches long — a finding the researchers said could help to identify such eggs more easily in the future and gain greater insight into the nesting habits of the creatures

Further analysis showed that the tyrannosaurs were born with distinct physical traits, including “a pronounced chin” — making them look “remarkably like their parents,” who could weigh up to 8 tons as adults, the researchers said

“These are just the first clues to understanding baby tyrannosaurs,” Funston wrote, “but now we know where to look, and what we’re looking for.”
