We report a new occurrence of the phyllodontid teleost fish Egertonia isodonta from the Late Cretaceous Kallamedu Formation of the Cauvery Basin, South India. This is the oldest occurrence of Phyllodontidae in India, and only the second Cretaceous Gondwanan occurrence of this genus, following a toothplate previously described from the Late Cretaceous Maevarano Formation, Madagascar. The presence of phyllodontid fish supports a fluvial-deltaic or brackish environment for the lower part of the Kallamedu Formation, a rich deposit including typically Gondwanan taxa, such as simosuchid crocodiles, bothremydid turtles, and abelisaurid dinosaurs, as well as an anomalous troodontid dinosaur. Egertonia adds another taxon of primarily Laurasian distribution to the Kallamedu fauna and further expands the taxa known from the Late Cretaceous of both India and Madagascar, suggesting a strong degree of faunal similarity between the two land masses nearly twenty million years after their separation.
