Description: Authentic Nanotyrannus lancensis Dinosaur Tooth 1.36 Inches Long Hell Creek Formation, Cretaceous Age 2005 Powder River County, Montana 68-66 Million Years This is a beautiful tooth from Nanotyrannus lancensis was found in the Hell Creek Formation Carter County, Montana, USA. It comes in a 4 3/8 x 3 3/8-inch Riker style display case for easy transport and display. A numbered Certificate of Authenticity (COA) matching the number on your specimen is included with each specimen. Paleontologists have long debated whether Nanotyrannus is a distinct species or just juvenile T-rexes. Most paleontologists are convinced they are actually juvenile T-rex. However, even after 70 years of study and debate there are still those that believe Nano is a separate genus. However, you believe Nanotyrannus lived alongside T-rex but was much smaller, up to 17 feet long and up to 3300 pounds with much smaller teeth. They were gracile (slender) and built more for speed than power. Nanotyrannus is a truly fascinating story both evolutionarily and historically. Found alongside its much larger cousin, the infamous T-rex, paleontologists have long debated whether Nanotyrannus is a distinct species or just juvenile T-rexes. This fierce debate continues today, with many paleontologists 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 paper published by the U.S. Department of the Interior Bureau of Land Management in 2020 written by paleontologist Holly Woodward and colleagues from Oklahoma State University note that most paleontologists are convinced that ?Nanotyrannus specimens are actually juvenile T-rex specimens. However, even after 70 years of findings and debate there are still those that believe Nanotyrannus is a separate genus. 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 stubby, two fingered iron fists and growing to over 40 feet in length and over 15 tons of muscle teeth and claws!! Unlike other carnivorous dinosaurs, T-rex was extraordinarily bulky and muscular. There were some carnivorous dinosaurs who exceeded T-rex in length. Its teeth were much thicker than other carnivorous dinosaur teeth to withstand its gargantuan bite force, bearing more of a resemblance to serrated spikes than serrated knives. The juveniles were gracile (slender) 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 lifetime, spitting out an old tooth when a new one was ready to take its place.
