Bone Analysis Suggests Small T. Rexes Were Not a Separate Genus; They Were Kids (4 of 5)

Caption

Juvenile Tyrannosaurus rex were fleet-footed with knife-like teeth, dominating the mid-carnivore niche before growing up to become the giant, bone-crushing King of Dinosaurs.. This material relates to a paper that appeared in the 1 Jan. 2020, issue of Science Advances, published by AAAS. The paper, by H.N. Woodward at Oklahoma State University Center for Health Sciences in Tulsa, OK, and colleagues was titled, " Growing up Tyrannosaurus rex: Osteohistology refutes the pygmy "Nanotyrannus" and supports ontogenetic niche partitioning in juvenile Tyrannosaurus."
