Data for: Giant longirostrine crocodylians from the Early Miocene of Pakistan: new material and taxonomical review

This study, based on previously undescribed crocodile remains from the Early Miocene of the Bugti Hills (Balochistan, Pakistan), reveals the existence of at least three distinct species. It confirms the validity of the species initially identified as \"Gavialis\" pachyrhynchus, establishing it as the sister taxon to the massive Miocene crocodile Rhamphosuchus crassidens. Consequently, it is reclassified as Rhamphosuchus pachyrhynchus. Additionally, \"Gharialis\" curvirostris is now acknowledged as a valid species under the new genus name Pseudogavialis, closely related to Gavialis. Another set of remains represents a third species, although the poor preservation hinders precise identification. The phylogenetic relationships between Tomistoma and Gavialis are one of the most debated issues in crocodylian phylogeny. Molecular analyses suggest a sister-taxa relationship dating back to the Early Miocene, while morphological analyses place Gavialis at the base of the tree, diverging from thoraco..., , , # Data for: Giant longirostrine crocodylians from the Early Miocene of Pakistan: new material and taxonomical review

## Description of the data and file structure

The fossil crocodylian material of the Bugti Hills studied in this work was collected during the 1995 and 1996 expeditions of the “Mission Paléontologique Française au Baloutchistan” (MPFB). The material (more than 350 fragments, with more than 120 of mandibles, maxillae, and premaxillae) was collected from the level 0 (Rupelian, Lower Oligocene), level 4 (Aquitanian, Lower Miocene), but also from the levels 5 and 6 (Fig. 1B.; Burdigalian, Lower Miocene; Welcomme et al. 2001). The material, although fragmentary, is well preserved overall, and the studied specimens are listed in Courville et al. (2025, Table 1). The fossils are only slightly deformed, but often embedded in compact ferruginous sandstones typical of the \"Bugti Bone Bed\" levels (...,
