trochanteric crest

Notably, the lateral trochanteric crest is elevated over a large antitrochanteric facet, and somewhat recurved over it.

The elevated lateral trochanteric crest is an autapomorphic feature of and plesiomorphic among Neornithes, as far as is known.

Holtz and Osmólska (2004) diagnosed the clade Maniraptora based on the following characters: reduced or absent olecranon process of the ulna, greater trochanter and cranial trochanter of the femur fused into a trochanteric crest.
