Study of Late Triassic Vertebrate Fossils from Tiki Formation, Shahdol District, Madhya Pradesh

Abstract

The objective of the study is to analysis the micro-vertebrate fossil assemblage from Tiki Formation of Late Triassic period and also reveals the significance of paleo-geography and paleo-environment of Tiki Formation, Shahdol District, Madhya Pradesh. Approximately, 1200kg of sample have been collected from Shahdol district, MP. After, washing it properly with water, acetic acid and kerosene, Trinocular Microscope is used for further analysis. Micro-vertebrates which are found in study are Cladodus sp., Actinopterygiian fish, Coelacanthidae fish, Metoposaurian clavicle, Parvodus tikinesis, Archosauriformes indent., Rewacondon tikiensis, Parasuchus hispoli, cynodont, Phytosaur. These faunas are closely resembles with different formation such as Maleri formation in Pranhita-Godavari basin, India, Santa Maria formation of Brazil, Ischiguelasto formation of Argentina, Chinli formation of USA, Dockum fauna of North America with the possibly migration occur during Late Triassic through northern Africa. Thus, it show the global palaeo-biogeographic scenario of Late Triassic time is closely co-relatable Late Triassic taxa in different continents which might have served a relatively rapid intercontinent passage of the vertebrate community extending across the ancient Supercontinent, Pangea.
