A Therizinosaur (Theropoda, Therizinosauridae) from the Late Cretaceous of Tajikistan

A theropod femur from the Late Cretaceous Kansai locality in Tajikistan (Yalovach Formation, Santonian) is referred to the family Therizinosauridae based on a combination of the following derived characters: the bone is straight in the anteroposterior plane; the femoral head is directed dorsomedially; the femoral neck is constricted between the femoral head and the great trochanter; the great trochanter and the femoral head are separated by a depression; the anterior trochanter is reduced, cylindrical; the ventral margin of the femoral head does not project beyond the margin of the femoral neck. The Kansai therizinosaur is most similar in the structure of the femur with unnamed therizinosaurs from the Turonian of Uzbekistan and the Santonian–Campanian of Western Kazakhstan.
