The Ichthyopterygia appeared in the fossil record as fully evolved, aquatic creatures, with nothing known about their transition from land to water, but now some light is shed on this transition by a fossil from the Lower Triassic of southern China of a small, primitive and possibly amphibious ichthyosaur-like creature, close to the common ancestry of ichthyosaurs and the obscure Hupehsuchia, a group of extinct aquatic reptiles known only from southern China.
