Ninjatitan (meaning "Ninja giant") is a genus of titanosaur sauropod dinosaur from the Early Cretaceous (Berriasian-Valanginian)-aged Bajada Colorada Formation of Argentina . It is the oldest titanosaur known to date and the type species N. zapatai was named and described in 2021.[1] Its generic name comes from a nickname of Argentine palaeontologist Sebastian Apesteguia, and the specific name comes from technician Rogelio Zapata.[2] It is known from postcranial remains discovered in 2014.[3][4]
Classification
Ninjatitan does not preserve any unanimous features that classify it as a somphospondylan, but it does bear features that suggest it can be included within the clade Titanosauria, either as a basal taxon or possibly within the clade Colossosauria. The phylogenetic results of Gallina and colleagues are shown below, where Ninjatitan was suggested to have multiple possible positions.[1]
