This article offers insight and research on how the bipedal theropod dinosaurs from the Triassic Period gradually modified their hindlimb function and form from hip-based to knee-based locomotion and from hip-abductor to hip-rotator balancing mechanisms as inherited by birds. The researchers also discovered how the ancestral specializations in larger Jurassic theropods became later lost in the bird-line, which further complicates the evolutionary paradigm.
