katodiles

Katodiles are a group of extinct marine reptiles that lived during the Late Triassic and Early Jurassic periods, approximately 230 to 180 million years ago. They are known for their distinctive, paddle-like limbs, which were adapted for a semi-aquatic lifestyle. Katodiles belong to the order Notosuchia, which also includes other semi-aquatic reptiles like metriorhynchids and nothosaurids.

The name "katodile" comes from the Greek words "katodos" meaning "descent" and "deilos" meaning "terrible," reflecting their fearsome appearance and their role as apex predators in their ecosystems. They were large predators, with some species reaching lengths of over 10 meters. Katodiles had a long, narrow snout filled with sharp teeth, which they used to capture and kill their prey, primarily other marine reptiles and fish.

Fossils of katodiles have been found in various locations around the world, including South Africa, Brazil, and China. Their remains typically consist of skull fragments, vertebrae, and limb bones. The study of katodile fossils has provided valuable insights into the evolution of marine reptiles and their adaptations to aquatic environments.

Despite their size and predatory nature, katodiles are not considered to be direct ancestors of modern crocodilians. Instead, they represent a separate branch of the reptile family tree, highlighting the diversity of Triassic and Jurassic ecosystems.
