HUGE NANOTYRANNUS Complete Tooth 1.75 In! Tyrannosaurus rex relative!

Description

Hi all!
This Is a HUGE GORGEOUS tooth from Nanotyrannus
lancensis
from the Hell Creek Formation in Montana, USA! The tooth has great serrations, a partial root, and an amazing tip! The tip broke off during it's discovery and was reattached. Neither part was repaired or altered in anyway! The dimensions measure about 1.75 x .6 x .36 inches which is HUGE for a Nanotyrannus!
Nanotyrannus is a truly fascinating story both evolutionarily and historically. Found alongside its much larger cousin, the infamous T-rex, paleontologist have long debated whether Nanotyrannus is a distinct species or just juvenile T-rexes. This fierce debate continues today, with many paleontologist subscribing to either side. If Nanotyrannus is a valid species, it represents a strange turn in Tyrannosaur evolution. During the last 15 million years of the Cretaceous period, the Tyrannosaurs of North America were getting progressively larger, a process which culminated in T-rex. Nanotyrannus however lived, alongside T-rex and yet was much smaller (about 16 feet long) than the proceeding Tyrannosaurs which it itself evolved from!
A great piece from a fascinating North American dinosaur at the center of one of the greatest debates in the history of paleontology!
