The Lameta Formation, also known as the Infratrappean Beds (not to be confused with the contemporaneous Intertrappean Beds), is a sedimentary geological formation found in Madhya Pradesh, Gujarat, Maharashtra, Telangana, and Andhra Pradesh, India, associated with the Deccan Traps.{{Cite journal |last1=Wilson Mantilla |first1=Gregory P. |last2=Renne |first2=Paul R. |last3=Samant |first3=Bandana |last4=Mohabey |first4=Dhananjay M. |last5=Dhobale |first5=Anup |last6=Tholt |first6=Andrew J. |last7=Tobin |first7=Thomas S. |last8=Widdowson |first8=Mike |last9=Anantharaman |first9=S. |last10=Dassarma |first10=Dilip Chandra |last11=Wilson Mantilla |first11=Jeffrey A. |date=2022-04-01 |title=New mammals from the Naskal intertrappean site and the age of India's earliest eutherians |url=https://www.sciencedirect.com/science/article/pii/S003101822200027X |journal=Palaeogeography, Palaeoclimatology, Palaeoecology |volume=591 |pages=110857 |doi=10.1016/j.palaeo.2022.110857 |bibcode=2022PPP...59110857W |issn=0031-0182|url-access=subscription }} It is of the Maastrichtian age (Late Cretaceous), and is notable for its dinosaur fossils.

History

The first fossils found in the Lameta Formation were discovered between 1917 and 1919.F. v. Huene and C. A. Matley, (1933), "The Cretaceous Saurischia and Ornithischia of the Central Provinces of India", Palaeontologica Indica (New Series), Memoirs of the Geological Survey of India 21(1): 1-74

The Lameta Formation was first identified in 1981 by geologists working for the Geological Survey of India (GSI), G. N. Dwivedi and Dhananjay Mahendrakumar Mohabey, after being given limestone structures–later recognised as dinosaur eggs–by workers of the ACC Cement Quarry in the village of Rahioli near the city Balasinor in the Gujarat state of western India.{{cite journal |last1=Wilson |first1=J.

Lithology

File:Rajasaurus en las traps del decán.jpg of the Deccan trap illustrating the paleoenvironment of Lameta formation]]

The formation is underlain by the Lower Cretaceous sedimentary "Upper Gondwana Sequence" also known as the Jabalpur Formation, and is overlain by the Deccan Traps basalt. The Lameta Formation is only exposed at the surface as small isolated outcrops associated with the Satpura Fault. The lithology of the formation, depending on the outcrop, consists of alternating clay, siltstone and sandstone facies, deposited in fluvial and lacustrine conditions. The environment at the time of deposition has alternatively been considered semi-arid, or tropical humid.{{Cite journal|last1=Srivastava|first1=Ashok K.|last2=Mankar|first2=Rupesh S.|date=January 2015|title=Lithofacies architecture and depositional environment of Late Cretaceous Lameta Formation, central India|url=http://link.springer.com/10.1007/s12517-013-1192-y|journal=Arabian Journal of Geosciences|language=en|volume=8|issue=1|pages=207–226|doi=10.1007/s12517-013-1192-y|bibcode=2015ArJG....8..207S |s2cid=67851941 |issn=1866-7511|url-access=subscription}}{{Cite journal|last1=Kumari|first1=Anjali|last2=Singh|first2=Seema|last3=Khosla|first3=Ashu|date=January 2021|title=Palaeosols and palaeoclimate reconstruction of the Maastrichtian Lameta Formation, Central India|url=https://linkinghub.elsevier.com/retrieve/pii/S0195667120303189|journal=Cretaceous Research|language=en|volume=117|pages=104632|doi=10.1016/j.cretres.2020.104632|bibcode=2021CrRes.11704632K |s2cid=224946979 |url-access=subscription}}

Fossil content

Many dubious names have been created for isolated bones, but several genera of dinosaurs from these rocks are well-supported, including the titanosaur sauropods Isisaurus and Jainosaurus and the Abelisaurs Indosaurus, Indosuchus, and Rajasaurus

and Noasaurids Laevisuchus.Weishampel et al., 2004, pp.517-606 Synapsids are also known form the formation, such as the possibly late surviving Avashishta,possibly the last known non- mammalian synapsid the possibly youngest known stegosaurian ichnogenus Deltapodus, madtsoiid snakes and other fossils.
