Diagnosis

---|---|---|
C. Mourer-Chauvire et al. 2011 | Diagnosis Large-sized femur, straight shaft, caudal face of
the shaft flattened, condylus lateralis and trochlea fibularis projecting laterally and distally, great development of the fossa poplitea, of the crista supracondylaris medialis, and of the osseous bar which joins the condylus medialis to the condylus lateralis. This unique combination of characters is found only in the family Phorusrhacidae. Comparatively to the Phorusrhacidae of similar or larger size (i.e., all the Phorusrhacidae apart from the Psilopterinae), Lavocatavis has the smallest distal end in relation to the total length of the femur. In addition, the proximo-distal diameter of the caput femoris, proportionally to the total length, is smaller in Lavocatavis than in the members of the family Phorusrhacidae. |
