A natural cranial endocast with possible dicraeosaurid (Sauropoda, Diplodocoidea) affinities from the Lower Cretaceous of Patagonia

A partially preserved sauropod natural cranial endocast (MLL-003) was collected from the Lower Cretaceous Mulichinco Formation in Argentina. The cast consists of cemented sandstone that has preserved in detail the general endocranial morphology, but not the cranial nerves. The dural expansion, the d...
