Ichthyolestes

Ichthyolestes is a genus of extinct marine reptiles that lived during the Late Triassic period, approximately 230 million years ago. The name Ichthyolestes translates to "fish thief," reflecting the reptile's likely diet of fish. Ichthyolestes is known from a single species, Ichthyolestes brevirostris, which was discovered in Germany.

Ichthyolestes was a small, slender reptile, with a long, narrow snout and sharp teeth adapted for catching and eating fish. It had a streamlined body, which would have helped it swim efficiently through the water. The reptile's limbs were relatively short and weak, suggesting that it was not a strong swimmer but rather a predator that stalked its prey from the water's edge or from the bottom.

Ichthyolestes is an important fossil because it provides insight into the early evolution of marine reptiles. It is one of the earliest known ichthyosaurs, a group of marine reptiles that dominated the oceans during the Mesozoic era. Ichthyolestes is also significant because it is one of the few known ichthyosaurs from the Late Triassic, a time when the group was still in the process of evolving and adapting to life in the ocean.

The fossil remains of Ichthyolestes have been found in Germany, and they include a partial skull, vertebrae, and limb bones. The skull is particularly well-preserved, and it shows that Ichthyolestes had a long, narrow snout with sharp teeth. The vertebrae are also well-preserved, and they show that Ichthyolestes had a long, slender body.
