The Indian Mesozoic dinosaur record is famous for documenting significant aspects of dinosaur evolution during the Triassic, Jurassic and Cretaceous periods. The Cenomanian–Turonian Nimar Sandstone, Lower Narmada valley, has produced fragmentary skeletal remains of Sauropoda indet. The Maastrichtian Lameta Formation has yielded at least 6 valid sauropod taxa and indeterminate titanosaurid remains, and at least 11 named (but likely oversplit) theropod taxa, i.e., 3 smaller-bodied species and 8 medium-to-large sized theropods. Apart from skeletal remains, Infra- and Intertrappean beds of peninsular India have yielded more than 10,000 dinosaur eggs belonging to 5 oofamilies and 15 oospecies. Most of the Indian ootaxa show distinct affinities with the Late Cretaceous ootaxa of four other continental areas – Spain, France, Argentina and Morocco. The presence of the two dominant oofamilies, Fusioolithidae and Megaloolithidae, in the Infra- and Intertrappean localities of peninsular India and three different continents (South America, Europe and Africa) further shows an ancient Gondwanan affinity and basic terrestrial association among these three landmasses. Based on the phylogenetic analysis of skeletal material, the most plausible pathway of dinosaur dispersal between India and Madagascar took place during the Late Cretaceous. The other conceivable dispersal pathway for the small animals was between India and Asia by means of the Kohistan Dras Volcanic Arc or a northeast pathway through Somalia, while the very large vertebrates, like theropod dinosaurs, may have emerged as a component of a ‘Pan Gondwanan’ model.

Several specimens derived from the Missourian (Pennsylvanian) deposits of the Glass Mountains (SW Texas, USA) are identified as Yuanophylloides Fomichev, 1953. Some species that earlier authors included in the genera Campophyllum Milne-Edwards and Haime, 1852, Bothrophyllum Trautschold, 1879, and Neokoninckophyllum Fomichev, 1939 are re-identified as belonging to Yuanophylloides. In addition to the type genus, a new subgenus Patulaxis of Yuanophylloides with the type species Y. (P.) molestus sp. nov. and the new species Y. (P.) parcus and Y. (P.) laxus are introduced. Re-identification of the upper Serpukhovian Campophyllum kansasense Miller and Gurley, 1893 as Yuanophylloides renders untenable the origin of that genus in the Donets Basin. The circum- Laurussia warm current is suggested as having carried Yuanophylloides larvae from the North American superprovince to the Paleotethyan superprovince. This genus supplements the group of genera suggested by Fedorowski (2023) as having originated in the North American superprovince and migrating to the Paleotethyan superprovince. Together, these genera demonstrate the importance of taxonomic investigation to establish paleobiogeography as a constrain on global (i.e., tectonic scale) environmental reconstructions.
