Ida is a well-preserved fossil of a primate that lived around 47 million years ago during the Eocene epoch. Discovered in Germany, this fossil is significant because it provides insight into the early evolution of primates. Ida is classified as a member of the group Euprimates, which includes modern primates like monkeys and apes. The fossil is notable for its remarkable state of preservation, including soft tissues and fur, which are rare in the fossil record. Ida has been described as a potential link between lemurs and other primates, helping scientists understand the transition from tree-dwelling creatures to more advanced primate forms.
