Well-preserved dinosaurian eggs from the infratrappean limestone of Kheda district, Gujarat are described. The mode of occurrence of these eggs and their distribution pattern suggest them to be autochthonous egg clutches. The distribution of these egg clutches indicates that dinosaurs probably nested in colonies.

Partial Skeletal remains of a juvenile sauropod have been recovered from one of the dinosaur egg clutches found in arenaceous limestone of the Upper Cretaceous Lameta Formation in Dholi Dungri in Panchmahals district, Gujarat. India. The estimated length of the skeleton is 40 cm. It is represented by vertebral column, humerus, scapula, ilium, skull fragments and other indeterminate fragments. This paper records the first find of a juvenile dinosaur in India.- Upper Cretaceous Dinosaur Eggs from New Localities of Gujarat, India

New occurrences of well-preserved dinosaur eggs have been found in the Lameta sediments near Dohad in Panchmahals district, Gujarat. The new localities lie 90 km east of the well-known Balasinor-Rahioli belt, which has the distinction of being one of the few dinosaur nesting sites in the world. The dinosaur eggs are spherical and have nodose ornamentation. Two types of egg shells have been distinguished on the basis of their microstructure. The egg shelIs have affinity towards sauropod types and are comparable to those of Kheda Type-B.- Avian Egg Shells from Pleistocene of Kutch

A well-preserved, nearly complete skeleton of the holostean fish Pycnodus lametae, is described from the freshwater Upper Cretaceous Lameta Formation of Bhatali in Chandrapur district of Maharashtra. Earlier, the genus was known only by its partly-preserved crushed skull. However, isolated crushing teeth are widely known from the Lameta and Interttappean sediments of Peninsular India. Other associated fishes include Holostei: Lepidotes deccanensis, Lepisosteus indicus; Teleostei: Clupeidae, Osteoglossidae, Enchodus, Eoserranus: and myliobatoids including Dasyatis and Igdabatis.Keywords

A diversified palynoassemblage has been recorded from the Singpur intertrappean of Chhindwara District, Madhya Pradesh, that has earlier yielded megafloral remains. The section is strategic as it is located between the Chhindwara-Mandla-Jabalpur(CMJ) sector to the north and Nand-Dongargaon (ND) basin to the south, that have so far produced a majority of the palynologically studied intertrappean sections associated with the Deccan Volcanic Sequence (DVS). In this context the palynological assessment of the Singpur intertrappean is critical for establishing a spatio-temporal correlations of the sediments of the two widely separated volcanic sub-Provinces/regions.The Singpur palynoassemblage shows presence of marker Late Cretaceous (Maastnchtian) palynotaxa viz. Aquilapollemtes bengalensis, Anadnaespontes sp., Gabonisports spp. and Pulcheripollemtes cauvenana associated with primitive stephanocolpate pollen. The appearance of polyaperturate pollen grains in the central India is significant as it suggests the evolutionary trend in the angiosperms during latest Cretaceous. The overall assemblage of the Singpur is indicated to be coeval with the Sindhi intertrappean bed of ND basin, and younger than the dinosaur bearing intertrappean beds of Mohagaon kalan (well section) and Ranipur of CMJ sector in the north. It is also indicated that the famous iridium bearing intertrappean section at Anjar (Kutch) associated with dinosaurs (Titanosaurus indicus) and deposited during 29 R, is older to the Singpur intertrappean bed.

A 164 m thick Deccan volcano sedimentary sequence comprising five flows, separated by four inter-Trap beds and overlying the Lameta Formation, has been encountered in borehole KA-I , drilled by the Directorate of Geology and Mining (DGM) for the coal exploration in Khandala-Ashta area of Wardha District, Maharashtra. Of these, the inter trap between the two lowermost flows has yielded a rich spore-Pollen assemblage that is dominated by angiosperms and pteridophytes. The presence of palynotaxa such as Azolla cretacea, Ariadnaesporites sp., Gabonisporis vigourouxii, Triporoletes reticulatus and Aquilapollenites bengalensis, suggests a Late Cretaceous (Maastrichtian) age for the sediments. The palynomorphs are associated with a rich dinoflagellate assemblage mostly comprising of Palaeoperidinium and Selenopemphix. The study indicates that the changing climatic and depositional scenario owing to Deccan volcanic eruption has possibly offered the suitable ecological niche for the first appearance of dinoflagellates and gradual domination of the angiosperm flora in the non-Marine ecosystem during Late Cretaceous in India.Keywords

Review of the available work on Indian dinosaurs shows that the majority of Indian dinosaur fossils are better known from Late Cretaceous sediments (Lameta and equivalents) than from the older pre-Late Cretaceous sediments or Gondwana Group (Triassic to Late Jurassic). Dinosaur eggs are so far unknown in the pre-Lameta dinosaurbearing sediments represented by Maleri (Carnian), Dharamaram (Norian to Rhaetian) and Kota (Liassic) Formations. Of these, the Kota Formation has yielded near-complete skeletons of Barapasaurus tagorei (a primitive sauropod) and Kotasaurus yamanapalliensis(a transitional prosauropod to early sauropod), which are at present the only two mounted dinosaur skeletons in India.The present article provides a brief historical review of the work on Indian dinosaurs. The stratigraphy, geology and geographical distribution of dinosaur-bearing sediments are discussed. The systematics of the Indian dinosaur species are briefly described. As the present author is mostly involved with the study of Indian Cretaceous dinosaurs and their eggs, it would only be apt in this article to place emphasis on Late Cretaceous dinosaurs and their eggs. A wide diversity is observable in the Indian dinosaur eggs, which are parataxonomically assigned to oofamily Megaoolithidae, Elongatoolithidae and Spheroolithidae. The problems involved in relating the varied Indian egg oospecies to their parent dinosaur are very challenging. However, based on the existing knowledge, the megaloolithid and elongatoolithid eggs can be attributed to titanosaurid and abelisaurid dinosaurs. Nesting behaviour of these dinosaurs is discussed in this paper. Evidences suggest that the environment during Late Cretaceous in India provided an ideal niche for the preferred habitat of these dinosaurs having an acme of their breeding and nesting. However, these reptiles struggled to survive the initial onslaught caused by the Deccan volcanic eruption near the end of Cretaceous.
