Late Cretaceous
Species - Tyrannosaurus Rex
Specimen - Femur Section
Discovered - South Dakota, Hell Creek Formation
 
Tyrannosaurus Rex, also known as T. Rex, was one of the largest and most fearsome carnivorous dinosaurs that roamed the Earth during the late Cretaceous era, approximately 68 to 66 million years ago. T. Rex lived in what is now North America and was one of the last dinosaur species to exist before the mass extinction that wiped out all non-avian dinosaurs.
 
The Hell Creek Formation of South Dakota is one of the most famous dinosaur fossil sites in the world and is known for its extensive collection of T. Rex fossils. This formation is a geological deposit that formed during the late Cretaceous period, approximately 66 to 68 million years ago. It is a vast area of sedimentary rocks that extends across parts of Montana, North Dakota, South Dakota, Wyoming, and Alberta, Canada. It is believed that the T. Rex lived in this area during this time and hunted other dinosaurs, such as Triceratops, Ankylosaurus, and Edmontosaurus.
 
The T. Rex was a massive dinosaur, measuring up to 40 feet long and weighing up to 9 tons. Its massive jaws were filled with sharp teeth that could measure up to 12 inches long. Its powerful hind legs allowed it to run at speeds of up to 20 miles per hour, making it one of the fastest and deadliest predators of its time. The T. Rex's iconic short arms may have been used for gripping and holding onto its prey while it tore into them with its massive jaws.
 
In conclusion, the Tyrannosaurus Rex was a formidable predator that lived in the Hell Creek Formation of South Dakota during the late Cretaceous era. Its massive size, sharp teeth, and powerful legs made it one of the most fearsome creatures to ever walk the Earth. The Hell Creek Formation remains one of the best places in the world to study the T. Rex and learn more about this incredible dinosaur.
