Eivertebrae

Eivertebrae are a group of extinct marine reptiles that lived during the Late Triassic period, approximately 230 to 200 million years ago. They are known for their distinctive, elongated necks and small, paddle-like limbs, which they used for swimming. Eivertebrae are believed to have been semi-aquatic, spending much of their time in the water and only coming onto land to lay their eggs.

The name "Eivertebrae" comes from the Greek words "eis" meaning "into" and "vertebra" meaning "vertebrae," reflecting their unique neck structure. Their elongated necks were composed of numerous small vertebrae, allowing for a high degree of flexibility and movement. This adaptation is thought to have been crucial for their hunting and feeding strategies, enabling them to capture prey with precision.

Eivertebrae are classified within the order Eivertebrata, which also includes the closely related genus Erythrosuchus. Fossils of Eivertebrae have been found in various locations around the world, including South Africa, Argentina, and China. These fossils provide valuable insights into the evolution of marine reptiles and their adaptations to aquatic environments.

Despite their unique features, Eivertebrae are relatively poorly understood due to the limited number of fossils available. Ongoing research continues to shed light on their biology, behavior, and ecological role during the Triassic period.
