Lohuecosuchus (Lo Hueco Crocodile) is an extinct genus of crocodyliforms related to the current crocodiles. They lived during the Upper Cretaceous (upper Campanian-Lower Maastrichtian) in what is now Spain and southern France.[1] It is a genus closely related to Allodaposuchus, a crocodile that lived in what is now Romania. It was both synchronic and sympatric with another allodaposuchid species, Agaresuchus fontisensis.[2]

Its endocranial anatomy was recently described and 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]
