Lameta Formation (India)

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. [1] 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. [2]

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. [3]

Lithology

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. [4] [5]

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 . [6] Mammals are also known form the formation, such as the possibly late surviving Avashishta , the possibly youngest know stegosaurian Deltapodus , madtsoiid snakes and other fossils.

<i>Rajasaurus</i> Abelisaurid dinosaur genus from Late Cretaceous India

Rajasaurus is a genus of carnivorous abelisaurid theropod dinosaur from the Late Cretaceous of India, containing one species: Rajasaurus narmadensis. The bones were excavated from the Lameta Formation in the Gujarat state of Western India, probably inhabiting what is now the Narmada River Valley. It was formally described by palaeontologist Jeffrey A. Wilson and colleagues in 2003 based on a partial skeleton comprising the braincase, spine, hip bone, legs, and tail–a first for an Indian theropod. The dinosaur likely measured 6.6 metres (22 ft), and had a single horn on the forehead which was probably used for display and head-butting. Like other abelisaurids, Rajasaurus was probably an ambush predator.

<i>Jainosaurus</i> Extinct genus of dinosaurs

Jainosaurus is a genus of titanosaurian sauropod dinosaur of India and wider Asia, which lived in the Maastrichtian. It is thought to have been about the same size as its contemporary relative Isisaurus, measuring 18 metres (59 ft) long and weighing 15 metric tons. The humerus of the type specimen is 134 centimetres long.

<i>Dravidosaurus</i> Extinct species of reptile

Dravidosaurus is a controversial taxon of Late Cretaceous reptiles, variously interpreted as either a ornithischian dinosaur or a plesiosaur. The genus contains a single species, D. blanfordi, known from mostly poorly preserved fossils from the Coniacian of southern India.

O. barasimlensis is known from five dorsal vertebrae, and O. mobilis from four smaller vertebrae, found at the same location.

<span class="mw-page-title-main">Judith River Formation</span> Fossil-bearing geologic formation in Montana, part of the Judith River Group

The Judith River Formation is a fossil-bearing geologic formation in Montana, and is part of the Judith River Group. It dates to the Late Cretaceous, between 79 and 75.3 million years ago, corresponding to the "Judithian" land vertebrate age. It was laid down during the same time period as portions of the Two Medicine Formation of Montana and the Oldman Formation of Alberta. It is an historically important formation, explored by early American paleontologists such as Edward Drinker Cope, who named several dinosaurs from scrappy remains found here on his 1876 expedition. Modern work has found nearly complete skeletons of the hadrosaurid Brachylophosaurus.

<i>Madtsoia</i> Extinct genus of snakes

Madtsoia is an extinct genus of madtsoiid snakes. It is known from the Eocene of Argentina, the Paleocene of Brazil, the Late Cretaceous (Maastrichtian) of India, and the Late Cretaceous (Maastrichtian) of Madagascar. The type species was the largest with an estimated length of 9–10 m (30–33 ft), and the other three species were smaller. A 5.1 m (17 ft) long M. madagascariensis would have weighed 50 kg (110 lb), but an isolated specimen suggests that this species reached 8 m (26 ft) in maximum length.

<span class="mw-page-title-main">Javelina Formation</span> Geological formation in Texas, USA

The Javelina Formation is a geological formation in Texas. Dating has shown that the strata date to the Maastrichtian stage of the Late Cretaceous, approximately 70 to 66.5 million years old. The middle part of the formation has been dated to about 69 million years ago plus or minus 1 million years and the top situated near the Cretaceous–Paleogene boundary, dated to 66 Ma ago. Dinosaur remains are among the fossils that have been recovered from the formation.

Bahariasauridae is a potential family of averostran theropods that might include a handful of African and South American genera, such as Aoniraptor, Bahariasaurus, Deltadromeus, and Gualicho. The placement of these theropods is controversial, with some studies placing them as basal ceratosaurs possibly related to Noasauridae, others classifying them as megaraptorans, basal neovenatorids, or basal coelurosaurs. There is also a possibility the group might not be monophyletic, as a monograph on the vertebrate diversity in the Kem Kem Beds published in 2020 found Bahariasaurus to be nomen dubium. In the same paper Deltadromeus is classified as an noasaurid, a result also recovered by some previous studies. A 2024 phylogenetic analysis found Aoniraptor, Bahariasaurus, Deltadromeus, and Gualicho to form a monophyletic clade as the sister taxon to Elaphrosaurus near the base of Ceratosauria.

The Intertrappean Beds are a Late Cretaceous and Early Paleocene geologic formation in India. The beds are found as interbeds between Deccan Traps layers, including the slightly older Lameta Formation. The formation spans the Cretaceous–Paleogene boundary, with a stratigraphic range of only a few hundred thousand years before and after the boundary, and a significant debate exists about whether specific sites belong to the Cretaceous or the Paleocene.

<i>Rahiolisaurus</i> Genus of abelisaurid dinosaur from the Late Cretaceous period

Rahiolisaurus is a genus of abelisaurid theropod dinosaur which existed in India during the Late Cretaceous period. It was described in 2010, based on fossils recovered from the Lameta Formation in the Indian state of Gujarat. These fossils include elements from at least seven different individuals and are believed to have been from the Maastrichtian stage, sometime between 70 and 66 million years ago, making it one of the last non-avian dinosaurs known in the fossil record. Despite representing a variety of different growth stages, all recovered fossils from the locality indicate a single species, the type species Rahiolisaurus gujaratensis.

Deccanolestes is a scansorial, basal Euarchontan from the Late Cretaceous (Maastrichtian) and Paleocene Intertrappean Beds of Andhra Pradesh, India. It may be closely related to Sahnitherium. Deccanolestes has been referred to Palaeoryctidae in the past, but recent evidence has shown that it is either the most basal Euarchontan, as the earliest known Adapisoriculid, or as a stem-afrotherian.

<i>Camarillasaurus</i> Extinct genus of dinosaurs

Camarillasaurus is a genus of theropod dinosaur from the Early Cretaceous period (Barremian) of Camarillas, Teruel Province, in what is now northeastern Spain. Described in 2014, it was originally identified as a ceratosaurian theropod, but later studies suggested affinities to the Spinosauridae. If it does represent a spinosaur, Camarillasaurus would be one of several spinosaurid taxa known from the Iberian peninsula, the others being Iberospinus, Protathlitis, ‘’Baryonyx’’, Riojavenatrix, and Vallibonavenatrix.

Avashishta bacharamensis is an extinct genus of a possibly late surviving haramiyid from the Maastrichtian Lameta formation of India. It is known from a solitary molariform tooth. It might represent the last known non-mammalian synapsid.
