Donodontidae is an extinct family of cladotherian mammals known from the Late Jurassic and Early Cretaceous of North Africa.
A pair of sharp keels, the paracristid and protocristid, project away from the protoconid and sharply curve lingually to meet the paraconid and metaconid, respectively.
The tip of the paraconid also sends down a smaller keel along its mesiolingual surface, adjacent to cusp e.[1] The upper molars, which are only known in Donodon and Stylodens, are semi-triangular.
Prototribosphenida is the mammalian subgroup containing Tribosphenida (true Laurasian tribosphenic mammals) and certain close relatives such as amphitheriids and peramurids.
[4] African cladotherians are widely distributed and taxonomically diverse, suggesting that the early evolution of Cladotheria was not restricted to Laurasia as commonly believed.
