For context, throughout the Pleistocene, terror birds were found only in the Americas. [18] Examination of phorusrhacid habitats also indicates that phorusrhacids may have presented intense competition to predatory metatherian sparassodonts such as borhyaenids and thylacosmilids, causing the mammalian predators to choose forested habitats to avoid the more successful and aggressive avian predators on the open plains.

Phorusracos isn't known as the Terror Bird only because that's much easier to pronounce; this flightless prehistoric bird must have been utterly terrifying to the small mammals of middle Miocene South America, in light of its enormous size (up to eight feet tall and 300 pounds), clawed wings, and heavy, crushing beak. Ever since the discovery of its type fossil in 1887, Phorusrhacos has gone by a bewildering number of now-outmoded or reassigned names, including Darwinornis, Titanornis, Stereornis, and Liornis. However, several fossil finds of smaller forms have been described from the late Pleistocene of South America.

It had been thought the fearsome beasts became extinct as little as 10,000 years ago - a time when humans shared their North American habitat. Coelurosaurs apparently used their long tail as a balance while running; phorusrhacoids probably used their reduced wings for the same purpose.

However, new fossils have been discovered in Comallo, Argentina. By the way, Phorusrhacos was closely related to another "terror bird" of the Americas, Titanis, a comparably sized predator that went extinct at the cusp of the Pleistocene epoch--to the extent that a minority of experts classify Titanis as a Phorusrhacos species.

Instead, it uses its wings primarily for balance during its high-speed sprints. However, even with these attributes, the phorusrhacids are often assumed to have preyed on relatively small animals (about the size of a rabbit) that could be dispatched with a minimum of struggle.

The etymology of the name Phorusrhacidae is based on the type genus Phorusrhacos.

This is disputable as many big-game hunting predators such as Smilodon, great white sharks and Allosaurus have weaker bite forces and often laterally weak skulls as adaptations towards, not away from, killing large prey, relying instead on the presence of a cutting edge, a wide gape made possible by the reduction of jaw musculature, and the driving force of the body or neck. eaters.

Terror Birds evolved in South America and crossed into North America via the Panamanian land bridge about 5 million years ago. The first evolved around 62 million years ago and the last perished about 2.5 million years ago, most of them playing the part of apex predator among the forests and plains of ancient South . Ecology. They named it the 'terror bird' for good reason: it was ten feet tall and ate meat. this prehistoric bird could certainly wreak its share of mayhem: at eight feet tall and 300 pounds (give or take a few inches and pounds for possible sexually dimorphic differences between males and females), the early pleistocene titanis closely resembled its theropod dinosaur forebears that went extinct 60 million years before, especially One day, Keith Stern (Craig Nigh), a birdwatcher is in the woods for his usual thing, when he stumbles across an This idea is no longer considered valid, as improved dating on Titanis specimens show that the last phorusrhacids went extinct over one million years before humans arrived. [24], All phorusrhacids are thought to have been carnivorous. [4]) The population of phorusrhacids declined thereafter according to older hypotheses, suggesting that competition with newly arrived predators was a major contributor to their extinction. This is because with the phorusrhacids' beak proportions, the jaw could not generate a great deal of bite force with which to kill the prey. [6] However, reports from Uruguay of new findings of a relatively small form (Psilopterus) dating to 18,000[7] and 96,000[8] years ago would imply that phorusrhacids survived there until very recently (i.e., until the late Pleistocene); the initial report of such a recent date has been questioned.
