Bone Analysis Suggests Small T. Rexes Were Not a Separate Genus; They Were Kids (3 of 5)

Caption

A thin slice of bone was removed from the tibia (shin-bone) of the T. rex, "Jane", and examined with a microscope. Bone tissue reveals Jane was a teenager and still growing when it died. 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."
