Month of Mesozoic Mammals #18: Leaps and Bounds Catopsbaatar

Known from the Late Cretaceous of Mongolia (85-70 mya), Catopsbaatar was a fairly large multituberculate, similar in size to a modern chinchilla at about 40-50cm long (1′4″-1′8″) with about half of that length being its tail.

It was part of a group of Asian multis called the djadochtatheriids, which lived alongside famous dinosaurs like Velociraptor in a sandy desert environment. They were mostly jerboa-like animals capable of bipedal hopping -- although one member of the group, Mangasbaatar, was a burrower instead.

Although Catopsbaatar had features in its vertebrae and hindlimbs convergently similar to those of modern hopping mammals, the somewhat more sprawling posture of multis mean it wouldn’t have jumped in quite the same way. It may have actually launched itself upwards at a steeper angle, in a manner a little more like a frog.

Djadochtatheriids weren’t the first hopping Mesozoic mammals, however, since fossilized footprints are known from both the Mid-Jurassic of South America and the Early Cretaceous of Korea. We don’t know what types of mammals made these tracks, or what they looked like, but they show that similar styles of locomotion may have evolved multiple times in early mammals.

Catopsbaatar

Catopsbaatar. Catopsbaatar was a rodent-like mammal in the order Multituberculata that lived in what is now Mongolia during the Late Cretaceous epoch, about 72 million years ago. The first fossils were collected in the early 1970s, and the species received its own genus (Catopsbaatar, Greek and Mongolian for 'visible hero') in 1994. Five skulls, one molar, and one skeleton with a skull are known. The skull of Catopsbaatar was up to 70 mm (2.8 in) long, heavy-set and wide, with the zygomatic arches strongly expanded to the sides. The ankles had spurs like those of the male platypus and echidna, but apparently without the platypus's venom canal. The spurs of Catopsbaatar and other Mesozoic mammals may have been used for protection against theropod dinosaurs and other predators. Like other members of its order, this species probably gave live birth, and the presence of hair indicates it was warmblooded. Its fossils were found in the Red Beds of Hermiin Tsav and the Barun Goyot Formation in Mongolia. via Blogger https://ift.tt/2xwMbE8
