There is a world somewhere between reality and fiction. Although ignored by many, it is very real and so are those living in it. This forum is about the natural world. Here, wild animals will be heard and respected. The forum offers a glimpse into an unknown world as well as a room with a view on the present and the future. Anyone able to speak on behalf of those living in the emerald forest and the deep blue sea is invited to join.

Carcharodontosaurusis a genus of carnivorous carcharodontosaurid dinosaur that existed during the Cenomanian stage of the mid-Cretaceous period. It is currently known to have been among the largest theropods found, with known specimens significantly larger than Tyrannosaurus rex and on par with or approaching the estimated body mass for Giganotosaurus and Spinosaurus. The genus Carcharodontosaurus is named after the shark genus Carcharodon. itself composed of the Greekkarchar[os] ( meaning "jagged" or "sharp") and odōn ("teeth"), and the suffix -saurus ("lizard"). Carcharodontosaurus includes some of the longest and heaviest known carnivorous dinosaurs, with various scientists proposing length estimates for the species. Based on relatives such as Giganotosaurus, the neotype of Carcharodontosaurus (SGM-DIN 1) would have been roughly 13-13.7 meters long and 9000-9800 kg. But this specimen was only a subadult, so adults would have been even larger. Carcharodontosaurus were carnivores, with enormous jaws and sharp, serrated teeth (just like those of sharks, hence the same) up to 20 cm long. A skull length of over 1.6 meters has been restored for C. saharicus. In 2001, Hans C. E. Larsson published a description of the inner ear and endocranium of Carcharodontosaurus saharicus. Starting from the portion of the brain closest to the tip of the animal's snout is the forebrain, which is followed by the midbrain. The midbrain is angled downwards at a 45-degree angle and towards the rear of the animal. This is followed by the hindbrain, which is roughly parallel to the forebrain and forms a roughly 40-degree angle with the midbrain. Overall, the brain of C. saharicus would have been similar to that of a related dinosaur, Allosaurus fragilis. Larsson found that the ratio of the cerebrum to the volume of the brain overall in Carcharodontosaurus was typical for a reptile.Carcharodontosaurus also had a large optic nerve.
