Here, we describe an oxidized mesoeucrocodylian tooth from the Adamantina Formation (Bauru Group) of southern Goiás state in Brazil. Despite poor preservation, several morphological features permit identification as an indeterminate sphagesaurian: bulbous triangular crown with a ‘teardrop-shaped’ cross-section; and strong constriction between the crown and deep root. The Adamantina Formation tooth is not only the first notosuchian recorded from the mid-west region of Brazil, but also represents one of the largest sphagesaurians ever described.
