- This is an EXTREMELY RARE tooth!! This rooted tooth was still in the developmental stage inside the T-Rex’s Jaw… This full sized but very thin tooth itself was growing inside the jaw and up into the socket of the tooth it would soon replace.. it would grow layers of enamel and serrations over time and the pressure would cause the weakened tooth above it to be pushed out an replaced. This specimen was just starting to show it’s serrations. VERY RARE and VERY COOL!! The specimen measures approx. 2 1/16″ long and will come in the 5.25″ x 6.25″ Riker Mount with Label as Shown
Aside from being one of the largest of the known carnivorous dinosaurs, Tyrannosaurus rex — T. rex, for short — is the dinosaur that has arguably received the most media exposure. It had a starring role in the “Jurassic Park” movies and has a renowned exhibit at the American Museum of Natural History in New York City.
The name Tyrannosaurus rex means “king of the tyrant lizards”: “tyranno” means tyrant in Greek; “saurus” means lizard in Greek, and “rex” means “king” in Latin. In 1905, Henry Fairfield Osborn, president of the American Museum of Natural History at the time, named Tyrannosaurus rex.
T. rex was a member of the Tyrannosauroidea family of huge predatory dinosaurs with small arms and two-fingered hands.
