Phorusrhacidae: Classification, Description & Palaeobiology

Phorusrhacidae, colloquially known as terror birds, is a family of large carnivorous, mostly flightless birds that includes possibly several subfamilies containing many genera, including the eponymous Phorusrhacos. The exact number of genera is uncertain, as some taxa such as Brontornis may be different forms of bird instead. All phorusrhacids lived…
