Size comparison. At the time of its discovery, Cartorhynchus was the smallest-known member of the Ichthyosauriformes.The preserved specimen had a length of 21.4 centimetres (8 in); assuming that it had tail proportions comparable to close relatives, Motani and colleagues estimated a full body length of 40 centimetres (1 ft 4 in) and a weight of 2 kilograms (4.4 lb).
Acamptonectes is a genus of ophthalmosaurid ichthyosaurs, a type of dolphin-like marine reptiles, that lived during the Early Cretaceous around 130 million years ago.
