Lavocatodus is an extinct genus of lungfish from Africa. The type species L. giganteus lived in Mali between the Maastrichtian age of the Late Cretaceous and the Lutetian age of the Eocene.[2] Two other possible species, L.? humei and L.? protopteroides, are known from the Campanian Quseir Formation in Egypt,[3] but their taxonomic position within the genus is uncertain.[1] Some researchers included Lavocatodus within the family Lepidosirenidae,[2][3] but Longrich (2017) recovered both Lavocatodus and Xenoceratodus within a separate family Lavocatodidae.[1]
