T-rex Dinosaur Hand Claw Fossil Replica

Description

T-rex dinosaur hand claw fossil replica measures 2.0 x 0.75 x 1.10 inches. The claw is a museum-quality polyurethane resin cast. 1:1 scale. Made in USA.

An adult T. rex had very short arms that ended in only two clawed fingers. They had a tiny, useless third finger bone that remained completely hidden beneath their skin. The hand claws grew short and heavily curved with sharp points at the tips. The inner curve of each claw featured a deep grove to anchor tight finger muscles.

Scientists debate exactly how the giant dinosaur used these small weapons during the Late Cretaceous period. The arms could lift over four hundred pounds despite their tiny size. The predator used the sharp claws to hook and hold struggling prey close to its chest. This grasping action kept the prey still so the dinosaur could deliver a fatal bite with its massive jaws.

Scientists found these small hand traits on famous skeletons inside the Hell Creek Formation. Real hand claws remain very rare because the small arm bones easily scattered before fossilization occurred.  A thick shell of tough keratin covered each core bone when the animal lived.
