Lohuecosuchus (meaning "Lo Hueco crocodile") is an extinct genus of crocodyliforms related to the current crocodiles. It lived during the Late Cretaceous (late Campanian to early Maastrichtian) in what is now Spain and southern France. Fossils of the genus have been recovered from the Villalba de la Sierra Formation at Lo Hueco.[2]

Description[]

The anatomy of the endocranium (braincase) of L. megadontos was found to be similar to crown-crocodylians, revealing that the acute sense of olfaction and low frequency hearing found in living crocodylians likely originated along the stem-line.[3]

Classification[]

Lohuecosuchus is closely related to Allodaposuchus, a crocodile that lived in what is now Romania, and may have been part of the same genus.[4] It was both synchronic and sympatric (lived at the same time and place) with another allodaposuchid species, Agaresuchus fontisensis,[5] which may also be part of Allodaposuchus.[4]
