Discovered in Miocene rocks of Comallo, Argentina, it appears to be a phorusrhacine closely related to Devincenzia, another of those obscure taxa known from pretty good remains.
Patagornis and the giant phorusrhacine were predicted to have running speeds of 14 metres per second (about 50 km/h) while Mesembriornis had a ridiculous predicted running speed of 27 metres per second (about 97 km/h).
Based on limb proportions and limb bone strength, Blanco & Jones (2005) estimated the running speed of the mesembriornithine Mesembriornis, the patagornithine Patagornis, and a giant phorusrhacine specimen from the Pliocene or Pleistocene of Uruguay.
All of this has been inspired by Chiappe & Bertelli’s (2006) description of the immense new specimen BAR 3877-11, an unnamed Miocene phorusrhacine phorusrhacid that represents one of the biggest members of the group: its skull is 71 cm long and the live animal probably stood 3 m tall (life restoration at left).
