酷東西

趣味知識

Planicoxa's name means 'flat hip' because its hip bone (ilium) had a flat, folded-over part that no other dinosaur had.1

The species name 'venenica' is Latin for 'poison', after the Poison Strip Sandstone where the fossils were found.1

Scientists found several partial skeletons of Planicoxa, including well-preserved hip bones, thigh bones, shin bones, and backbones.1

Planicoxa lived about 129 to 125 million years ago, during the Early Cretaceous period.1

A second species once thought to belong to Planicoxa was later moved to its own genus, Osmakasaurus.1
