asiattomina

Asiatomina is a genus of extinct sharks that lived during the Early Cretaceous period, around 145 to 100 million years ago. They belonged to the family Odontaspididae, which is a group of primitive sharks that were characterized by their primitive teeth and body shape.

Fossil evidence of Asiatomina has been found in geological formations in Asia, including China and Mongolia. The genus was first described in 1967 by paleontologist Wu Ruiqi, who named it based on a collection of fossil teeth found in the Yixian Formation in northeastern China.

Asiatomina was a relatively small shark, estimated to have been about 2-3 meters in length. Its teeth were short and pointed, with a distinctive V-shaped notch at the base of each cusp. The teeth were also quite robust, suggesting that the shark may have been an apex predator in its ecosystem.

Studies of Asiatomina fossils have provided important insights into the evolution of sharks during the Early Cretaceous period. The genus is considered to be a transitional form between the Cretaceous Period's early shark faunas and the more modern shark faunas that followed.

The find of Asiatomina fossils in Asia has also contributed to our understanding of the geological history of the region. The Yixian Formation, where the fossils were found, is a significant geological formation that has yielded many important fossil discoveries, including those of early mammals and dinosaurs.
