Teen T-rex had monster growth spurt
Towering Tyrannosaurus rex reached its colossal proportions due to a monster growth spurt in its teenage years, reveals a new study… Gregory Erickson, a palaeontologist at Florida State University in Tallahassee, US, has collected a large number of small, discarded T. rex bones sitting in museum drawers, and found the bones contain a treasure trove of well preserved growth rings inside. These cast-offs have allowed Erickson and his colleagues to chart out the first growth curve for T. rex.
