Abstract

Two almost complete teeth, one anterior and one lateral, of the extinct shark Megascyliorhinus miocaenicus (Antunes & Jonet, 1970) are reported from the early Pliocene of San Quirico d'Orcia, Tuscany, central Italy. The teeth are similar in size and morphology (vertical striations of the crown base, indistinct cutting edge of the crown and accessory cusplets) to conspecific teeth described in literature. This is the first unequivocal report of a rare and enigmatic shark in the Pliocene of central Italy. A Pliocene tooth from Allerona, Umbria, central Italy, formerly assigned to Scyliorhinus sp., may also belong to Megascyliorhinus miocaenicus.
