Description

Vahiny was first described and named by Kristina Curry Rogers and Jeffrey A. Wilson in 2014 and the type species is Vahiny depereti. It is known solely from the Late Cretaceous Maevarano Formation located in northwestern Madagascar, together with the more common titanosaur, Rapetosaurus krausei. Rapetosaurus is the most common dinosaur in its fauna and is known from hundreds of bones, including multiple partial skeletons and skulls, while other taxa are extremely rare, including Vahiny identified from a partial braincase. Vahiny is distinguished from other titanosaurs by characteristics of its braincase, including the basal tubera, basipterygoid processes, parasphenoid, and cranial nerve foramina. Differences in the braincases of Vahiny and Rapetosaurus indicate that they are not closely related to one another. Vahiny is most similar to Jainosaurus from the Late Cretaceous of India, and bears similarities to the South American taxa Muyelensaurus and Pitekunsaurus.[1]

gollark: Why use electricity and not light or something?
gollark: Great, I'll forward that to the President of Physics.
gollark: Also, they would take infinite time and materials to build, and light lag between bits of the computer would be a problem.
gollark: Do you want the extra space to have things in it or not have things?
gollark: Hmm, good idea. What sort of features do you want?
