Zapteryx

Zapteryx was a genus of Late Triassic placodont reptiles. These marine reptiles were characterized by their flattened bodies and crushing dentition, which they likely used to feed on shellfish and other hard-shelled invertebrates. Fossils of Zapteryx have been found in Europe.

Zapteryx belongs to the Placodontia, an extinct order of reptiles known for their specialized adaptations to a marine lifestyle. While not closely related to modern turtles, they share some superficial resemblances, such as a broad, protective shell in some species within the order. Zapteryx itself, however, possessed a less developed shell compared to some of its placodont relatives.

The exact phylogenetic relationships of Zapteryx within Placodontia are still subject to research and debate. Its anatomy contributes to understanding the diversity and evolutionary history of these unusual reptiles from the Triassic period. Fossil evidence, primarily consisting of jaw fragments and other skeletal elements, provides insight into their morphology and lifestyle.
