Name: Arcusaurus pereirabdalorum
Name Meaning: Rainbow lizard
First Described: 2011
Described By: Yates et al.
Classification: Dinosauria, Saurischia, Eusaurischia, Sauropodomorpha
Arcusaurus was a basal sauropodomorph from the Hettangian to Sinemurian ages of the Early Jurassic, somewhere between 201 and 190 million years ago. It was found in the Elliot Formation of South Africa, and is known from a partial skull and some remains from juvenile individuals. As such, its adult size is uncertain; not only are the juveniles themselves not complete and not able to have size extrapolated from them; but adult size cannot be determined from these scant remains either. Phylogenetic studies place it as a basal sauropodomorph, sister taxon of Efraasia, however its scant remains does leave this under some confusion. Arcusaurus also lived much later than Efraasia, creating a 35 million year ghost lineage of sauropodomorphs. Arcusaurus also has many features unique to more advanced groups including Plateosauria. More remains will need to be found to answer the questions at hand. As to the question of feathers, given its basal position in the dinosaurian family tree, and the ancestral trait of feathers for all dinosaurs, and its relative distance from the known to be scaly sauropods; it is not unreasonable to suppose that it would have been covered in a similar coating as Kulindadromeus.
