3.5" Fossil Tyrannosaur Vertebra Centrum - Montana
This is a 3.5" tall vertebra centrum from a large theropod dinosaur, with the two most likely candidates being Tyrannosaurus rex and Nanotyrannus lancensis, collected from the Hell Creek Formation of Montana. Everything superior to the bases of the pedicles is missing and there is a repaired crack through the middle of the bone. Beautiful cortical bone preservation can be found in spots around the vertebra.
Comes with an acrylic display stand.
True Tyrannosaurus rex and Nanotyrannus lancensis material is some of the most sought after and collectable fossil material out there.
Paleontologists debate contentiously about whether Nanotyrannus lancensis and Tyrannosaurus rex (T. rex) are really the same species, where Nanotyrannus represent juveniles. Papers going back and forth on the topic continue to be published, but even more fossil evidence under study has yet to be published. We tend to fall into the camp that Nanotyrannus is in fact a separate species.

About Tyrannosaurus rex
Perhaps the most famous of all dinosaurs, Tyrannosaurus rex (abbreviated as T.rex, not T-Rex) was the largest terrestrial carnivore in North America 66 million years ago, in the Late Cretaceous period. Reaching adult sizes of 39-42 feet and 7-9 tons, this formidable predator was also one of the largest terrestrial carnivores to ever live, second only to the African Spinosaurus and possibly rivaled by the South American Giganotosaurus.
Tyrannosaurus was likely an opportunistic predator, hunting when it could and scavenging when it couldn't, using its fantastic senses of sight and smell to track potential meals. When it did need to hunt, it had a pair of powerful jaws full of 6-inch teeth that could deliver over 4 tons of pressure per square inch when they bit down. Their arms, by comparison, are infamously small.
Tyrannosaurus rex is known from an abundance of well-articulated specimens, including juveniles and subadults, so their growth patterns are well documented. It seems Tyrannosaurus grew relatively quickly, the first ten years reaching about a tenth of their adult size, then rapidly growing to their titanic adult forms in another ten. Based on growth signs in adult specimens, it would seem that Tyrannosaurs rarely lived to be more than thirty: most specimens died in their mid to late twenties. Based on pathologies of fossil bone, we can deduce that this was at least in part due to their dangerous adult lifestyle. Preying on well defended herbivores like Triceratops, Ankylosaurus, and large Hadrosaurs would have been a difficult undertaking, and healed injuries on the bones of these herbivores show that the hunts were not always successful.
Nevertheless, this great predator was one of the largest and most fearsome of the carnivorous dinosaurs, and living at the end of their age, it comes as no surprise that it be dubbed such an imposing name as "Tyrant Lizard King".

The Hell Creek Formation
Renowned for both its age and rich sedimentary layers, the Hell Creek Formation is one of the most intensively studied fossil-bearing regions on Earth. To date, scientists have documented 158 genera of animals and 64 genera of plants from its rocks, with new finds emerging regularly. Beyond iconic dinosaurs such as tyrannosaurs, ceratopsians, and hadrosaurs, the formation has produced an extraordinary array of life, including amphibians, reptiles, lizards, snakes, turtles, fish, sharks, birds, and early mammals. Together, these fossils provide the most complete picture of the ecosystems that thrived just before the Cretaceous–Paleogene extinction event.
