Abstract

Titanosaur sauropods are a common component of the Upper Cretaceous fauna of the Serra da Galga Formation, Tria<^>ngulo Mineiro region, Minas Gerais, Brazil. Among these, three distinct tooth morpho-types are recognized and described here. One of the teeth represents the largest titanosaur tooth ever found, whereas others correspond to possible juveniles. This diversity of morphologies, sizes, and ontogenetic stages shows that the Serra da Galga environment supported a diverse titanosaur fauna. & COPY; 2023 Elsevier Ltd. All rights reserved. (AU)
