Аннотация:The stages of development of the acetabular foramen in archosaurs are considered. The function of
this foramen in crocodiles and birds is analyzed. It is proposed that the formation of the acetabular foramen in
a number of advanced thecodonts was associated with the use of two essentially different modes of locomotion
and, consequently, different functional modes of the hip joint (as observed in living crocodiles) in the course of
a high-rate evolutionary transition from the lateral (sprawling) limb posture to the parasagittal posture.
