a nutshell Kotasaurus is one of the most primitive sauropod
discovered. So primitive is Kotasaurus that the
genus still possesses
features that are known in sauropodomorph
dinosaurs. This led to a
lot of initial confusion over whether Kotasaurus
was an advanced
sauropodomorph, or a primitive sauropod, though today the
interpretation of Kotasaurus as a very primitive
sauropod holds greater
favour amongst palaeontologists.
The first fossils of Kotasaurus were found in the Kota Formation, and hence the name of the genus which means ‘Kota lizard'. Another sauropod dinosaur named Barapasaurus is also known from this formation, though Kotasaurus is significantly more primitive in overall form than Barapasaurus.
