linguicauda

Linguicauda is a genus of extinct ray-finned fish that lived during the Late Jurassic epoch. Fossils of Linguicauda have been found in what is now Europe, particularly in Germany. This ancient fish is known for its distinctive elongated body and a caudal fin that tapers to a whip-like end, a feature that gives it its name, derived from Latin words for "tongue" and "tail."

The skeletal structure of Linguicauda indicates it was a predatory fish, likely inhabiting shallow marine environments. Its teeth suggest it fed on smaller invertebrates or possibly other small fish. While not as well-known as some other Jurassic marine reptiles, Linguicauda provides valuable insights into the diversity of fish life during the Mesozoic Era. Its discovery contributes to our understanding of piscine evolution and the paleoecology of ancient seas. The limited fossil record means much about its specific behavior and life cycle remains speculative.
