operacinius

Operacinius is a genus of small, extinct mammals that lived during the Eocene epoch, approximately 56 to 34 million years ago. The genus is known from fossil remains found in Europe, particularly in Germany and France. Operacinius is characterized by its small size, with body lengths ranging from 10 to 20 centimeters, and its primitive dental structure, which includes both incisors and molars.

The genus Operacinius is notable for its evolutionary significance. It represents one of the earliest known members of the order Primates, which includes modern primates such as monkeys, apes, and humans. The fossils of Operacinius provide valuable insights into the early evolution of primates and their ancestors.

The name "Operacinius" is derived from the Latin words "operculum," meaning "lid" or "cover," and "cynus," meaning "dog." This name reflects the genus' small size and primitive dental structure, which are reminiscent of those found in early mammals.

Operacinius is classified within the family Adapisoridae, which is a group of small, primitive primates that lived during the Eocene epoch. The family Adapisoridae is further divided into several subfamilies, including the Operaciniinae, which includes the genus Operacinius.

In summary, Operacinius is a genus of small, extinct mammals that lived during the Eocene epoch. It is characterized by its small size, primitive dental structure, and evolutionary significance as one of the earliest known members of the order Primates. The genus is known from fossil remains found in Europe and is classified within the family Adapisoridae.
