Synonyms

Enalioetes is an extinct genus of metriorhynchid thalattosuchian from the Early Cretaceous Stadthagen Formation of Germany. The type species is E. schroederi.[1]

Prior to its description in 2024,[2] it was known under the informal names Enaliosuchus "schroederi" and Cricosaurus "schroederi".[3][1]

Discovery and naming

The holotype, which consists of much of the skull as well as parts of the neck, was discovered no later than 1921 in the Stadthagen Formation, Germany. It was assigned to the genus Enaliosuchus by Schroeder (1921) after he compared the specimen to the holotype of Enaliosuchus macrospondylus.[4][2] Kuhn (1936)[3] was the first to use name Enaliosuchus "schroederi", however it was not established correctly.[2]

The name Enaliosuchus "schroederi" was considered to be a junior synonym of Enaliosuchus macrospondylus by Hua et al. (2000),[5] although the authors Steel (1973), Young & Andrade (2009) and Sachs et al. (2020) considered the species to be valid.[6][1][7]

Sachs et al. (2024) reclassified Enaliosuchus "schroederi" into the new genus and species Enalioetes schroederi.[2]

Description

The genus is among the most recent metriorhynchids known and one of the best preserved Cretaceous members of its group, preserving much of the skull as well as parts of the neck.[2]
