Fossil Friday - Tumblr Posts

This Fossil Friday is a blast from the past! Snapped circa 1959, this photo depicts Tyrannosaurus rex and Triceratops on display in the Museum’s Hall of Late Dinosaurs. These iconic dinosaurs are still on display at the Museum, but they now sit in separate halls. You can find T. rex in the Hall of Saurischian Dinosaurs—saurischians are characterized by grasping hands, in which the thumb is offset from the other fingers. Triceratops is in the Hall of Ornithischian Dinosaurs, which displays dinosaurs that are characterized by a backward-pointing extension of the pubis bone. This bone was thought to have helped support the enormous stomachs that these animals needed to digest masses of tough vegetation!
