Erinevusutildes

Erinevusutildes is a genus of extinct mammals that lived during the Late Cretaceous period, approximately 72 to 66 million years ago. The genus is known from a single species, Erinevusutildes mongoliensis, which was discovered in Mongolia. This genus belongs to the order Multituberculata, a group of mammals that are characterized by their complex molar teeth and the presence of multiple tubercles (bumps) on their skulls.

Erinevusutildes mongoliensis is notable for its unique dental structure. The genus is distinguished by its molar teeth, which feature a complex pattern of ridges and grooves. These teeth are adapted for grinding and crushing plant material, suggesting that Erinevusutildes was likely a herbivorous animal. The molar teeth of Erinevusutildes are also unique in that they exhibit a form of dental replacement, where the teeth are continuously worn down and replaced by new teeth growing in behind them.

The fossil remains of Erinevusutildes have been found in the Djadochta Formation in Mongolia, which is known for its rich fossil record of Late Cretaceous mammals. The discovery of Erinevusutildes provides valuable insights into the diversity and evolution of mammals during the Late Cretaceous period. The genus represents an important addition to our understanding of the early evolution of mammals, highlighting the complexity and diversity of these animals during a time when they were still relatively rare and underrepresented in the fossil record.
