Phorusrhacos

Phorusrhacos (/ˌfɔːrəsˈrɑːkɒs/ FOR-əs-RAH-koss) is a genus of giant flightless terror birds that lived in Miocene Patagonia. The type species is P. longissimus. The closest living relatives of P. longissimus are the much smaller seriemas. It is thought to have lived in woodlands and grasslands.

Phorusrhacos grew up to 2.5 metres (8.2 ft) tall and weighed approximately 130 kilograms (290 lb).[1] They had large skulls, up to sixty centimetres (24 in) long, armed with powerful, hook-tipped beaks. The structure of the beak and the large claws on the toes show that they were carnivorous.
