Fig 7. Scanning Electron Micrographs ofMegaloolithus jabulpurensis (VPL/CCE—5C) eggshells. A, Fan shaped spherolith (SP) and pore canal (PC). B, Spongy layer of the spherolith magnified showing arcuate accretion lines and various fracture patterns. C, Spongy layer further magnified to show the typical “Herring-Bone” Pattern. D, Inner eggshell surface showing mamillae with resorption crater (RC). E, a pair of partly silicified fan-shaped speroliths with basal knobs. F, Basal knob (BK) magnified to show radiating patterns.

Crocodilian Nest in a Late Cretaceous Sauropod Hatchery from the Type Lameta Ghat Locality, Jabalpur, India
The well-known Late Cretaceous Lameta Ghat locality (Jabalpur, India) provides a window of opportunity to study a large stable, near shore sandy beach, which was widely used by sauropod dinosaurs as a hatchery. In this paper, we revisit the eggs and eggshell fragments previously assigned to lizards from this locality and reassign them to crocodylomorphs. Several features point to a crocodilian ...
متن کاملA Sauropod Braincase from the Pab Formation (Upper Cretaceous, Maastrichtian) of Balochistan, Pakistan
Recent geological and paleontological exploration in the Pab Formation (Upper Cretaceous) of Balochistan Province has uncovered new terrestrial vertebrate remains. Together with Cretaceous vertebrates from India, the Pab vertebrates provide information about the paleobiogeographic history of Indo-Pakistan during its northward migration towards Asia. Vertebrate remains collected from several loc...
متن کاملNeurocranial Osteology and Neuroanatomy of a Late Cretaceous Titanosaurian Sauropod from Spain (Ampelosaurus sp.)
Titanosaurians were a flourishing group of sauropod dinosaurs during Cretaceous times. Fossils of titanosaurians have been found on all continents and their remains are abundant in a number of Late Cretaceous sites. Nonetheless, the cranial anatomy of titanosaurians is still very poorly known. The Spanish latest Cretaceous locality of "Lo Hueco" yielded a relatively well preserved, titanosauria...
متن کاملA new Argentinean nesting site showing neosauropod dinosaur reproduction in a Cretaceous hydrothermal environment.
Although several late Cretaceous sauropod colonial nesting sites have been discovered nearly on every continent during the last few decades, no studies have been performed to determine the factors that underpinned the choice of these specific sites. Here, we report the first definitive evidence of a group of sauropods that nested repetitively and purposely at a Cretaceous hydrothermal site at S...
متن کاملReassessment of the Sauropod Dinosaur Jainosaurus (=“antarctosaurus”) Septentrionalis from the Upper Cretaceous of India
Early evaluations of sauropod diversity in the Cretaceous of India recognized three genera, “Titanosaurus,” Antarctosaurus, and Laplatasaurus, each of which was thought to have closely related species on other southern landmasses. Recent systematic work has challenged the validity of the genus “Titanosaurus” and the supposed close relationship between its constituent species, particularly those...
