Description
Paraphysornis was 2.4 m (7 ft 10 in) tall and weighed approximately 180 kilograms (400 lb). It was calculated at having been around 1.4 m (4 ft 7 in) high at the back.[2] Like Brontornis, Paraphysornis is more massively built than other phorusrhacids and has a shorter and stouter tarsometatarsus, which indicates less cursorial and possibly carrion-feeding habits.[3]
Discovery
The nearly complete (%75) skeleton of one specimen (DGM-1418-R) recovered from the Tremembé Formation of the Taubaté Basin. The specimen only lacks most of the upper maxilla, braincase, pelvis and sternum.[2] In the Museum of Natural History of Taubaté is exposed the almost complete skeleton of Paraphysornis found in 1982 by Herculano Alvarenga.
