A carcharodontosaurid theropod dinosaur that lived in Northern Africa around 95 million years ago. It was two meters longer than Tyrannosaurus Rex (T Rex) and coexisted with Spinosaurus Aegyptiacus. However, Spinosaurus ate fish while Carcharodontosaurus preyed on Ouranosaurus, so they did not have to battle often. Carcharodontosaurus did not have jaws capable of breaking bone, unlike Tyrannosaurus, but instead had serrated teeth that could cut through flesh. In fact, the name literally means "Shark Toothed Lizard!" Carcharodontosaurus was typically an ambushing predator and was also territorial, as bite marks from the same species have been found on the skulls.

Get the Carcharodontosaurus mug.Carnosauria is a large group of predatory dinosaurs that lived during the Jurassic and Cretaceous periods. While it originally contained a wide assortment of giant theropods that were not closely related, the group has since been defined to encompass only the allosaurs and their closest kin. Starting from the 1990s, scientists have discovered some very large carnosaurs in the carcharodontosaurid family, such as Giganotosaurus, Carcharodontosaurus, and Tyrannotitan which are among the largest known predatory dinosaurs.
Distinctive characteristics of carnosaurs include large eyes, a long narrow skull and modifications of the legs and pelvis such as the thigh (femur) being longer than the shin (tibia).

Carnosaurs first appeared in the Middle Jurassic, around 176 mya. The last definite known carnosaurs, the carcharodontosaurs, became extinct in the Turonian epoch of the Cretaceous, roughly 90 mya; reportedly later remains of carcharodontosaurids, from the Campanian and Maastrichtian epochs, are likely misidentified remains of abelisaurids. The phylogenetically problematic megaraptorans, which may not be carnosaurs, became extinct around 84 mya.

Get the Carnosaur mug.Albertosaurus (/ælˌbɜ rtəˈsɔ rəs/; meaning "Alberta lizard") is a genus of tyrannosaurid theropod dinosaur that lived in western North America during the Late Cretaceous Period, about 70 million years ago. The type species, Albertosaurus sarcophagus, was apparently restricted in range to the modern-day Canadian province of Alberta, after which the genus is named. Scientists disagree on the content of the genus, with some recognizing Gorgosaurus libratus as a second species.
As a tyrannosaurid, Albertosaurus was a bipedal predator with tiny, two-fingered hands and a massive head that had dozens of large, sharp teeth. It may have been at the top of the food chain in its local ecosystem. While Albertosaurus was large for a theropod, it was much smaller than its larger and more famous relative Tyrannosaurus rex, growing nine to ten meters long and possibly weighing less than 2 metric tons.

Since the first discovery in 1884, fossils of more than 30 individuals have been recovered, providing scientists with a more detailed knowledge of Albertosaurus anatomy than is available for most other tyrannosaurids. The discovery of 26 individuals at one site provides evidence of pack behaviour and allows studies of ontogeny and population biology, which are impossible with lesser-known dinosaurs.
