Dactylosaurus (meaning "finger reptile" or "finger lizard") is a genus of small nothosauroid marine reptiles. The genus consists of only one known species; Dactylosaurus gracilis, which appears to be similar to the slightly larger Anarosaurus pumilio.Dactylosaurus live in the lower and middle triassic period during the olenekian and anisian.
D. gracilis is known from relatively poor fossil remains. The nasal bones of Dactylosaurus meet and are broadly structured. The upper temporal fenestra is large and kidney-shaped. There are 17 cervical vertebrae and the cervical ribs have anterior processes. The maxillae of Dactylosaurus extended broadly up the side of the snout.
Dactylosaurus is the second-smallest known fossil marine reptile after Keichousaurus; estimated to be roughly 60 centimetres in length.
