Baisesaurus (meaning "

Spathian) Luolou Formation of Guangxi, China. The genus contains a single species, B. robustus, known from a partial postcranial skeleton.[1]

Discovery and naming

The Baisesaurus

Longlin County, Baise, Guangxi region, China. The specimen consists of assorted ribs, gastralia, a limb element (likely a radius), 12 vertebral centra, and seven neural arches
.

In 2022, Ren et al. described Baisesaurus robustus, a new genus and species of basal ichthyosauromorph. 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]
