Titanis is a genus of Phorusrhacidae, or "terror birds". The extinct family of large, predatory birds originated in South America and inhabited parts of the present-day United States during the Pliocene. Like all phorusrhacids, Titanis had elongated hind limbs, a thin pelvis, proportionally small wings, and a large skull with a hooked beak. Estimates placed Titanis at 1.4 to 2 meters (4.6 to 6.6 ft) in height and over 300 kilograms (660 lb) in body mass. Phorusrhacids are thought to have been ground predators or scavengers, apex predators that dominated Cenozoic South America. They may have swallowed small prey whole or targeted larger prey with repeated strikes of the beak. Titanis likely preyed on mammals such as the extinct armadillo relatives Holmesina and Glyptotherium, equids, tapirs, capybaras, and other Pliocene herbivores. Titanis is unique among phorusrhacids in that it is the only one known from North America, crossing over from South America during the Great American Interchange. (Full article...)
