The hips consist of the pelvis, which includes three major bones : the illium ( top of the hip ), ischium ( sides of hip ), and pubis ( front of the hip ).

"Darwinopterus " is distinguished from its close relatives by the greater relative length of the back portion of the skull compared to its jaws, thin nasal bone, and elongated hip bone ( illium ).
23.
Unlike other rauisuchians, which have a prominent ridge on the illium called the supra-acetabular buttress that overlies the femur, " Stagonosuchus " possesses only a slight thickening on the surface of the bone.

In " Mass Effect 2 ", when Shepard goes to Illium and asks Liara about how she's been doing for the past two years, she eventually mentions a " friend " that she is looking for.
25.
Erythrosuchids are notable for being the first archosauriforms to have a triradiate pelvic girdle with three projecting areas formed from three bones : an illium and an elongated basal archosauriforms such as proterosuchids lacked these features and probably had a more sprawling posture.
26.
The illium of " Echinerpeton " is similar to those of early reptiles in that it is narrow and backward-pointing, while those of sphenacodontids are widened at their front to support the hip's connection with the sacral vertebrae.
27.
Parts of the appendicular skeleton ( limbs, hips, and shoulder bones ) are preserved in " Echinerpeton " specimens, including the interclavicle, scapula ( shoulder blade ), the lower portion of the humerus ( upper arm bone ), the illium ( a hip bone ), the upper portion of the femur ( upper leg bone ), the tibia and fibula ( lower leg bones ), astragalus and calcaneum ( ankle bones ), and metatarsals ( foot bones ).

""'Dagasuchus " "'is an extinct genus of pseudosuchian archosaur from the Middle Triassic of Rio Grande do Sul, Brazil, represented by the type species " "'Dagasuchus santacruzensis " "'. " D . santacruzensis " was named in 2015 on the basis of a partial hip ( one illium and a pair of ischia ) found in an exposure of the Santa Maria Formation near the city of Santa Cruz do Sul . " Dagausuchus " is an early member of a large evolutionary group called Loricata, which originated in the Triassic and includes modern crocodylians and their ancestors.
