Description
The Reinaut Formation in the south of the continent called Guralta is one of, if not the most extensive fossil site from the late Bobossic. Dated to have been formed between 125 and 122 million Eryobian years ago, the Reinaut Formation offers a glimpse of what life was like in the Kikilian, the latest stage of the Bobossic right before the devastating mass extinction dubbed “The World Scarring” happened.Back when it was formed, the Reinaut Formation was likely a subtropical or temperate open woodland subject to seasonal rains. The fossils discovered in the Reinaut Formation so far, have mostly been megafaunal animals which tended to fossilise better than smaller animals in the conditions that were present in Reinaut 122 million years ago.
Besides Saurochenia itself, Reinaut appears to have been home to a second Saurocheniid species, the much smaller and oddly proportioned Xenokadropeton agilis. While only being half the size of Saurochenia, Xenokadropeton had a skull that was the same size as the former’s, relatively shorter legs and a longer tail that almost made these two Sautocheniids the same length. The mouth of Xenokadropeton was close to the ground and its caecal digits were long and sported tong shaped claws, perhaps suggesting a mostly grazing lifestyle.
Like Saurochenia, Xenokadropeton fossils have been found in large numbers, suggesting a gregarious lifestyle and like modern Brachiostomes and possibly other Saurocheniids, Xenokadropeton had a single ear located behind the head that might have been colourful and used for display.
