Abstract

Turiasaurs are large-bodied eusauropods found in Early Jurassic to Early Cretaceous deposits across Gondwana and Laurasia. However, their early history is poorly known. Here, we report a lower-middle Bathonian turiasaur tooth from the Jaisalmer Basin in western India. Morphologically, the tooth is heart-shaped, typical of turiasaurs, and bears resemblance to a maxillary tooth. Although this is not the first turiasaur tooth reported from the basin, it represents the oldest occurrence of the clade in the Indian Subcontinent, approximately coeval with the oldest known turiasaurs elsewhere in Gondwana, advancing our spatio-temporal understanding of sauropod diversity in the Middle Jurassic.
