Rebbachisaurines
Rebbachisauridae is a family of sauropod dinosaurs known from fragmentary fossil remains from the Cretaceous The Cretaceous ( ) is a geological period that lasted from about 143.1 to 66 mya (unit), million years ago (Mya). It is the third and final period of the Mesozoic Era (geology), Era, as well as the longest. At around 77.1 million years, it is the ... of South America, Africa, North America, Europe and possibly Central Asia. Taxonomy In 1990 sauropod specialist Jack McIntosh included the first known rebbachisaurid genus, the giant North African sauropod ''Rebbachisaurus'', in the family Diplodocidae, subfamily Dicraeosauridae, Dicraeosaurinae, on the basis of skeletal details. With the discovery in subsequent years of a number of additional genera, it was realised that ''Rebbachisaurus'' and its relatives constituted a distinct group of dinosaurs. In 1997 the Argentine paleontologist José Bonaparte described the family Rebbachisauridae, and in 2011 Whitlock defined two ...

Katepensaurus
''Katepensaurus'' ("hole lizard") is an extinct genus of rebbachisaurid sauropod dinosaur known from the Late Cretaceous of south-central Chubut Province of central Patagonia, Argentina. It contains a single species, ''Katepensaurus goicoecheai''. Fossil record The holotype and only known specimen of ''Katepensaurus goicoecheai'' is UNPSJB-PV 1007, a partial skeleton from the Lower Member of the Bajo Barreal Formation of Chubut Province, Argentina. The specimen preserves one skull bone (a Frontal bone, frontal), three cervical vertebrae, six dorsal vertebrae, five caudal vertebrae, and several difficult-to-identify fragments, which probably include portions of additional vertebrae as well as possible fragments of some limb bones (a metacarpal or metatarsal and an Talus bone, astragalus). It represents an individual that was at least seven years old and had not finished growing when it died. The Lower Member of the Bajo Barreal Formation is considered to date to the Cenomanian or ...
