The Patcham Formation or Pachchham Formation is a Bathonian geologic formation of Patcham Island, Kutch district, Gujarat, India. Dinosaur remains are among the fossils that have been recovered from the formation, although none have yet been referred to a specific genus. [1]
The Indroda Dinosaur and Fossil Park in Gandhinagar, Gujarat, India, is a park that houses fossilized remains and petrified eggs of dinosaurs. It is a man-made fossil park and not the actual nesting grounds where the dinosaurs lived. The eggs and fossils on display here are from the world's 3rd-largest dinosaur fossil excavation site and 2nd-largest hatchery at Raiyoli, Balasinor, Gujarat. The Park was set up by the Geological Survey of India and is the only dinosaur museum in the country.
Macronaria is a clade of sauropod dinosaurs. Macronarians are named after the large diameter of the nasal opening of their skull, known as the external naris, which exceeded the size of the orbit, the skull opening where the eye is located. Fossil evidence suggests that macronarian dinosaurs lived from the Middle Jurassic (Bathonian) through the Late Cretaceous (Maastrichtian). Macronarians have been found globally, including discoveries in Argentina, the United States, Portugal, China, and Tanzania. Like other sauropods, they are known to have inhabited primarily terrestrial areas, and little evidence exists to suggest that they spent much time in coastal environments. Macronarians are diagnosed through their distinct characters on their skulls, as well as appendicular and vertebral characters. Macronaria is composed of several subclades and families notably including Camarasauridae and Titanosauriformes, among several others. Titanosauriforms are particularly well known for being some of the largest terrestrial animals to ever exist.
The Lameta Formation, also known as the Infratrappean Beds, is a sedimentary geological formation found in Madhya Pradesh, Gujarat, Maharashtra, Telangana, and Andhra Pradesh, India, associated with the Deccan Traps. It is of the Maastrichtian age, and is notable for its dinosaur fossils.
The Inferior Oolite is a sequence of Jurassic age sedimentary rocks in Europe. It was deposited during the Middle Jurassic. The Inferior Oolite Group as more recently defined is a Jurassic lithostratigraphic group in southern and eastern England. It has been variously known in the past as the Under Oolite, the Inferior Oolite, the Inferior Oolite Series and the Redbourne Group.
The Forest Marble is a geological formation in England. Part of the Great Oolite Group, it dates to the late Bathonian stage of the Middle Jurassic.
The Isalo III Formation is a geological formation in Madagascar, off the eastern coast of Africa. It dates back to the Middle Jurassic. The use of the term "Isalo III" is somewhat controversial as the two prior units Isalo I and II are Triassic cross-bedded sandstone units that form a continuous depositional sequence, while the "Isalo III" sandstones are not part of the same depositional sequence, and were deposited considerably later. and are perhaps better treated as part of several separate formations. It is traditionally divided into two subunits the lower, Bajocian aged Isalo IIIa unit also known as the Beronono Formation and the upper, Bathonian aged Isalo IIIb unit also known as the Sakaraha Formation or Sakahara Formation. The Sakaraha Formation consists of sandstones, marls and carbonates and represents a coastal plain environment, and is laterally equivalent to the predominantly carbonate Bemaraha Formation, which represents a coastal barrier lagoon complex. The formation is found in the northwest and in the southeast of the country and has provided a variety of fossils.
The Alcobaça Formation, previously known as the Guimarota Formation and also known as the Consolação Unit, is a geological formation in Portugal. It dates back to the Kimmeridgian stage of the Late Jurassic. It is an important source of information on the diversity of Late Jurassic mammals. Many of the fossils were collected from the now disused and flooded Camadas de Guimarota coal mine.
The Chari Formation is a Jurassic geologic formation in Gujarat, western India. Dinosaur remains are among the fossils that have been recovered from the formation, although none have yet been referred to a specific genus. The ammonite Reineckeia has also been found here. The skulls of two marine crocodiles have also been found and have been putatively identified as Steneosaurus.
The Kaladongar Formation is the oldest Mesozoic geologic formation of the Kachchh basin. It is found in Patcham Island, Kachchh, Gujarat, India. It is made up of limestone and sandstone. It was later intruded by an olivine gabbroic intrusion which baked and shattered the overlying Limestone. Dinosaur remains are among the fossils that have been recovered from the formation, although none have yet been referred to a specific genus.
The Valtos Sandstone Formation is a Middle Jurassic (Bathonian) formation found in the Inner Hebrides of Scotland. It is the thickest member of the Great Estuarine Group. The lithology consists of sets of approximately 6 metre thick cross bedded sandstone, capped by thin shelly limestones containing bivalves of the genus Neomiodon Dinosaur remains are among the fossils that have been recovered from the formation, although none have yet been referred to a specific genus.
The Tilougguit Formation, also known as the Tillouguit Formation, is an Early Bathonian geologic formation in Morocco. An indeterminate sauropod is known from the formation
The Katrol Formation is a Mesozoic geologic formation in India. Fossil Dinosaur tracks have been reported from the formation. An indeterminate ophthalmosaurid ichthyosaur is also known from the formation in the Kutch district.
The Bhuj Formation is a Mesozoic geologic formation in India. Fossil sauropod tracks and tracks from the ichnogenera Skolithos, Diplocraterion, Pholeus and Planolites have been reported from the formation.
Dacryomya, or the pointed nutclam is an extinct genus of small-sized saltwater clams, marine bivalve molluscs in the nutclam family Nuculanidae. The size and shape of the shells of species in this genus are reminiscent of broad apple pips.
The Rutland Formation is a geologic formation in England. It preserves fossils dating back to the late Bajocian to Bathonian stages in the Jurassic period, about 169 million years ago. It is the lateral equivalent of the Sharp's Hill Formation and the Fuller's Earth Formation. The "Rutland Dinosaur" specimen of Cetiosaurus is known from the formation.
The Chipping Norton Limestone is a geological formation in the Cotswolds, England. It preserves fossils dating back to the Bathonian. Including those of dinosaurs Cetiosaurus, Megalosaurus and Cruxicheiros as well as the Tritylodontid Stereognathus. It primarily consists of ooidal limestone.
The Moskvoretskaya Formation is a Middle Jurassic geologic formation in the European part of Russia. It consists of continental claystones, siltstones and sandstones deposited in karstified segments of underlying Middle Carboniferous limestone, that would have formed underground aquifers.
The Jaisalmer Formation is a Middle to Late Jurassic-aged geologic formation located in India near the city of Jaisalmer that consists mainly of marine deposits. The formation was first identified and defined by geologist Richard Dixon Oldham in 1886.
Tharosaurus is an extinct genus of dicraeosaurid sauropod dinosaur from the Middle Jurassic Jaisalmer Formation of India. The genus contains a single species, T. indicus, known from several vertebrae and a rib. Tharosaurus represents the earliest diplodocoid currently known and the first described from India.
The Khadir Formation is a geological formation in India. It is of Middle Jurassic age. Dinosaur bones are among the fossils recovered from the formation.
