Kemp, A. Journal of Vertebrate Paleontology. vol, 21. issue 1. 2001. pg 13-23. It is known only from Oligocene and Miocene-aged sediments in Australia, although phylogenetic evidence supports it having first diverged from its closest relative, Neoceratodus, during the Late Jurassic or Early Cretaceous period. 4 species are known from this genus:

†Mioceratodus anemosyrus †Mioceratodus diaphorus †Mioceratodus gregoryi †Mioceratodus poastrus
