A genus of extinct pelycosaur reptiles from the Permian period, characterized by a round vertebral structure.
From Greek 'kyklos' (circle), 'otos' (ear), and 'sauros' (lizard). Named in the early 20th century for the distinctive circular vertebral structures observed in fossil specimens, suggesting an adaptation related to hearing or spinal structure.
These strange Permian reptiles show up in the fossil record right before the great sail-backed creatures like Dimetrodon, giving us hints about how complex vertebrate body structures evolved! Their circular vertebrae were truly unusual and may have helped them survive in their desert environments.
