Cyclobatis is an extinct genus of stingray-like skate from the Upper Cretaceous of what is now Lebanon.[1][2] The genus is typified by a circular form.[1] The ray measures about 10 cm or 20 cm. In life the environment of this creature was a warm shallow sea. This fish had a very short tail, fitted with a venomous stinger.[1]
Two species are known. The shown, long-tailed Cyclobatis major and the short-tail Cyclobatis oligodactylus. Cyclobatis major can reach a length of about 25 cm, Cyclobatis oligodactylus around 15 cm
