Abstract

Four types of thin eggshells of dinosaurian and avian affinities are reported from the intertrappean sequences of Mohgaon-Kalan, Chhindwara District, Madhya Pradesh and the Lameta Formation of Dongargaon, Chadrapur District, Maharashtra, Central India. The morphological and microstructural characters of these 'very thin' eggshells namely (?) Hypselosaurus, indeterminate dinosaurian type and two types of avian eggshells are comparable with those from the Late Maastrichtain, Aix-en-Provence, France and some Mongolian eggshells. However, the abnormally thin nature of eggshells and the conspicuous absence of resorption craters shows that these eggs were under extreme environmental stress, primarily due to Deccan volcanism.
