Hell Creek Tyrannosaur Partial Tooth TYRANNOSAURUS REX or NANOTYRANNUS 1.4 IN!!

Description

Hi all!
This Is a Beautiful partial tooth from either a juvenile  TYRANNOSAURUS
REX
or a HUGE Nanotyrannus from the Hell Creek Formation in Montana, USA! The tooth has great serrations, a partial root, and zero repair or restoration! The outer enamel is missing from most of the tooth indicating it was swallowed and digested! The dimensions measure about 1.4 x .8 x .4 inches!
The Hell Creek Formation is home to two species of Tyrannosaur Dinosaur, T-Rex and Nanotyrannus
Even if you're not a paleontologist, or even a scientist, you've almost certainly heard of T-rex. The monster sized carnivore ruled Late Cretaceous North America with a stubby, two fingered iron fist! Growing to over 40 feet (12 meters) in length and over 15 TONS of muscle teeth and claws!! Unlike other carnivorous dinosaurs, T-rex was extraordinarily bulky and muscular. Although there were some carnivorous dinosaurs who exceeded T-rex in length, comparing them to T-Rex is like comparing a NBA player to a bodybuilder on steroids! This was reflected in its teeth which are much thicker than other carnivorous dinosaur teeth to withstand it's gargantuan bite force, bearing more of a resemblance to serrated spikes than serrated knives. The juveniles were more svelte than the adults, built more for speed than power. It has even been suggested that they would engage in cooperative hunting, the youngsters would use their speed to push potential prey towards the massive jaws of the adults. Like other dinosaurs, T-rex went through multiple sets of teeth in its life time, spitting out an old tooth when a new one was ready to take its place.
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!
Honesty and proper identification is very important to me. Although this specimen is without a doubt from either T-rex or Nanotyrannus I am not comfortable enough to place it in one or the other. What I am sure of is it's relation to the most iconic of carnivorous dinosaurs and that it would make a fantastic addition to any fossil collection!
