In 2022, Ren et al. describedBaisesaurus robustus, a new genus and species of basalichthyosauromorph. The generic name, "Baisesaurus", combines a reference to the type locality in Baise, China, with the Greek "saurus", meaning "lizard". The specific name, "robustus", means "robust".[1]
Description
Baisesaurus was likely at least 3 m (9.8 ft) long. It was more similar to Utatsusaurus than to any other ichthyosauromorph, with similar size and anatomical traits. It can be inferred from related animals that Baisesaurus was a strong swimmer with long, compact forelimb bones.[1]
Classification
Baisesaurus likely represents a basal member of the clade Ichthyosauromorpha. The describing authors explain that it may represent a member of the Ichthyopterygia. However, such a classification is highly tentative.[1]
