Lohuecosuchus

Lohuecosuchus (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. 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". Fossils of the genus have been recovered from the Villalba de la Sierra Formation at Lo Hueco.
Description.
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.
