GEOLOGY

Detailed explanation-1: -Joseph Burr Tyrrell, FRSC (November 1, 1858 – August 26, 1957) was a Canadian geologist, cartographer, and mining consultant. He discovered dinosaur (Albertosaurus sarcophagus) bones in Alberta’s Badlands and coal around Drumheller in 1884.

Detailed explanation-2: -Joseph Tyrrell was known for his amazing discovery of the Albertosaurus Sarcophagus. In 1884 he led a group of explorers and cartographers to find coal seams in Red Deer Valley. Instead he found Albertosaurus’ skull jutting out of the ground. Albertosaurus was the first of its genus.

Detailed explanation-3: -In 1884, Geological Survey of Canada geologist Joseph Tyrrell discovered an Albertosaurus skull in the badlands along the Red Deer River. This was the first time the world had seen Albertosaurus. It was a chance find as Tyrrell was exploring the river valley cliffs for coal.

Detailed explanation-4: -Albertosaurus sarcophagus was a large tyrannosaur from the Late Cretaceous of western North America. This fierce, meat-eating dinosaur was shorter and lighter than Tyrannosaurus rex and belongs in a different subfamily, Albertosaurinae, along with Gorgosaurus.

Detailed explanation-5: -Albertosaurus was a large bipedal predator but smaller than Tarbosaurus and Tyrannosaurus rex. Typical Albertosaurus adults measured up to 8–9 m (26–30 ft) long, and weighed between 1.7 and 2.5 metric tons (1.9 and 2.8 short tons) in body mass.
