Locality: Maevarano Formation, Mahajanga Basin, Boeny Region, northwestern Madagascar

Era: Late Cretaceous
Geological Age: 66–72 mya

Description: This one of a kind Sauropod hip bone sphere from northwestern Madagascar has a polished grey-brown surface with darker fossil bone patterning visible across the piece. The surface shows a mix of dense cell structure, fine webbing, and larger mineral-filled areas, giving it a natural organic pattern without being overly bright or high contrast. The quarter shown in the photos helps show the sphere’s larger display size.

Sauropods were huge long-necked dinosaurs, and hip bone came from one of the strongest parts of the skeleton. Over millions of years, mineral-rich groundwater moved through the porous bone, preserving the internal structure while replacing or filling the original material with stone.
