Is Daspletosaurus related to T rex?

Daspletosaurus is closely related to the much larger and more recent tyrannosaurid Tyrannosaurus rex. Like most tyrannosaurids, Daspletosaurus was a multi-tonne bipedal predator equipped with dozens of large, sharp teeth.

What did Daspletosaurus look like?

Daspletosaurus torosus was built much like T. rex but smaller, with a large skull and a long muscular tail. It had pronounced crests in front of and behind the eyes, giving it a distinctive appearance. This tyrannosaur was one of the first for which clavicles were described.

When did Daspletosaurus go extinct?

They appeared in Late Cretaceous times around 80 million years ago. Most of them vanished during the mysterious mass extinction of all dinosaurs, 65 million years ago. For some unknown reason, Daspletosaurus torosus came to an end about three million years before the great dinosaur extinction.

How was Dinosaur Park formed?

The Dinosaur Park Formation is composed of sediments that were derived from the erosion of the mountains to the west. It was deposited on an alluvial to coastal plain by river systems that flowed eastward and southeastward to the Bearpaw Sea, a large inland sea that was part of the Western Interior Seaway.

Who discovered the Daspletosaurus?

Charles Mortram Sternberg
Era & Discovery In some areas, Daspletosaurus coexisted with two other tyrannosaurids, Gorgosaurus and Albertosaurus. Daspletosaurus skeleton Daspletosaurus was discovered in 1921 near Steveville, Alberta, by Charles Mortram Sternberg, who thought it was a new species of Gorgosaurus.

What type of creature is a Albertosaurus?

Albertosaurus is a genus of large, meat-eating dinosaur (theropod). It lived between 73.1 and 69.6 million years ago. Skeletal remains of Albertosaurus have only been found in southcentral Alberta, in the Horseshoe Canyon Formation (see Badlands). Albertosaurus was the top predator in its ecosystem.

Where did the T Rex roam?

rex lived in the species’ native North America, possibly as far north as Alaska and as far south as Mexico, over a two- to three-million-year timespan. This research isn’t the first time that scientists have tried to estimate T. rex numbers. In fact, the average population density in the new paper—roughly one T.

Who discovered Daspletosaurus?

Era & Discovery In some areas, Daspletosaurus coexisted with two other tyrannosaurids, Gorgosaurus and Albertosaurus. Daspletosaurus was discovered in 1921 near Steveville, Alberta, by Charles Mortram Sternberg, who thought it was a new species of Gorgosaurus.

What is the importance of Dinosaur Provincial Park?

In addition to its particularly beautiful scenery, Dinosaur Provincial Park – located at the heart of the province of Alberta’s badlands – contains some of the most important fossil discoveries ever made from the ‘Age of Reptiles’, in particular about 35 species of dinosaur, dating back some 75 million years.

How big is a Dino PP?

The nearly 29-square-mile (75-square-km) park is best known for its extensive fossil beds, within which have been identified some 35 different species of dinosaurs from the Late Cretaceous Epoch (about 100 to 65 million years ago).

Is Albertosaurus bigger than Daspletosaurus?

Gorgosaurus is just a bit bulkier and more robust and Albertosaurus has more rounded lacrimal crests and the tip of the upper jaw is more rounded. Daspletosaurus is larger than the other two, it’s closer to T.

How is Daspletosaurus different from other dinosaurs?

Daspletosaurus was a medium-sized tyrannosaurid, being slightly taller than an average human. Daspletosaurus had a large skull, and had sturdier bones than other large theropods. Large fenestrae in the skull reduced overall body weight.

How many Dinosaur Park specimens have been collected?

A total of eight specimens have been collected from the Dinosaur Park Formation over the years since, most of them within the boundaries of Dinosaur Provincial Park. Phil Currie believes that the Dinosaur Park specimens represent a new species of Daspletosaurus, distinguished by certain features of the skull.

Is the tyrannosaurid from the Two Medicine formation Daspletosaurus?

Currie (2003) stated that the tyrannosaurid from the Two Medicine Formation mentioned by Horner et al. (1992) may be an unnamed third species of Daspletosaurus. Another partial skeleton was reported from the Upper Two Medicine in 2001, preserving the remains of a juvenile hadrosaur in its abdominal cavity.

What type of formation is the Dinosaur Park Formation?

Dinosaur Park Formation. Jump to navigation Jump to search. The Dinosaur Park Formation is the uppermost member of the Belly River Group (also known as the Judith River Group), a major geologic unit in southern Alberta. It was laid down during the Campanian stage of the Late Cretaceous epoch between 76.9 and 75.8 million years ago.
