Bathysuchus
''Bathysuchus'' ("deep water crocodile") is an extinct genus of teleosaurid thalattosuchian from Late Jurassic (Kimmeridgian) deep water marine deposits in England and France. ''Bathysuchus'' displays features that suggest it was more pelagic than other teleosaurids (along with its close relatives within the Aeolodontinae), including smoother skull bones and reduced armour plating, similar to the fully marine metriorhynchids. This was possibly an adaptation to rising sea levels during the Kimmeridgian, as its earlier relatives such as ''Teleosaurus'' were suited for shallow coasts and lagoon environments. Description ''Bathysuchus'' is a very long-snouted (longirostrine) teleosaurid, currently known only from several snouts, the back of the skull, teeth, and a few osteoderms. It is distinguished from other derived teleosaurids in the following characteristics: strongly ventrally deflected anterior margin of the premaxilla; five premaxillary alveoli, the caudal-most being cons ...

Aeolodontinae
Teleosauridae is a family of extinct typically marine crocodylomorphs similar to the modern gharial that lived during the Jurassic period. Teleosaurids were thalattosuchians closely related to the fully aquatic metriorhynchoids, but were less adapted to an open-ocean, pelagic lifestyle. The family was originally coined to include all the semi-aquatic (i.e. non-metriorhynchoid) thalattosuchians and was equivalent to the modern superfamily Teleosauroidea. However, as teleosauroid relationships and diversity was better studied in the 21st century, the division of teleosauroids into two distinct evolutionary lineages led to the establishment of Teleosauridae as a more restrictive family within the group, together with its sister family Machimosauridae. Amongst teleosauroids, teleosaurids were generally smaller and less common than machimosaurids, suggesting the two families occupied different niches, similar to modern species of crocodilians. However, teleosaurids were more diverse ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sericodon
''Sericodon'' is an extinct genus of teleosaurid crocodyliform from the Late Jurassic (Tithonian) of Germany and Switzerland. The genus contains a single species, ''S. jugleri''. ''Sericodon'' was placed in 'Clade T' (Aeolodontinae) and was found to be the sister taxon to ''Bathysuchus'', another teleosaurid. Taxonomy ''Sericodon'' was named for teeth from Late Jurassic deposits in Hanover, Germany, and Solothurn, Switzerland (Reuchenette Formation) by Hermann von Meyer in 1845.Meyer, H, (1845), Note on fossil reptiles: Neües Jahrbuch fur Mineralogie, Geologie und Palaontologie, 1845, p. 308-313. The genus was later synonymized with ''Steneosaurus'' by Steel (1973), but new work suggests it might be a distinct genus after all.Foffa D, Johnson MM, Young MT, Steel L, Brusatte SL. 2019.

Kimmeridge Clay Formation
The Kimmeridge Clay is a sedimentary deposit of fossiliferous marine clay which is of Late Jurassic to lowermost Cretaceous age and occurs in southern and eastern England and in the North Sea. This rock formation is the major source rock for North Sea oil. The fossil fauna of the Kimmeridge Clay includes turtles, crocodiles, sauropods, plesiosaurs, pliosaurs and ichthyosaurs, as well as a number of invertebrate species. Description Kimmeridge Clay is named after the village of Kimmeridge on the Dorset coast of England, where it is well exposed and forms part of the Jurassic Coast World Heritage Site. Onshore, it is of Late Jurassic (Kimmeridgian) age and outcrops across England, in a band stretching from Dorset in the south-west, north-east to North Yorkshire. Offshore, it extends into the Lower Cretaceous (Berriasian Stage) and it is found throughout the Southern, Central and Northern North Sea. The foundations of the Humber Bridge on the southern (Barton) side of the bridge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steneosaurus
''Steneosaurus'' (from el, στενός , 'narrow' and el, σαῦρος , 'lizard') is a dubious genus of teleosaurid crocodyliform from the Middle or Late Jurassic (Callovian or early Oxfordian) of France. The genus has been used as a wastebasket taxon for thalattosuchian fossils for over two centuries, and almost all known historical species of teleosauroid have been included within it at one point. The genus has remained a wastebasket, with numerous species still included under the label ''‘Steneosaurus’'', many of which are unrelated to each other (either paraphyletic or polyphyletic with respect to each other and other genera of teleosauroids). Discovery and assigned species The type species, ''S. rostromajor'', was only formally recognised as such in 2020, and this revision determined the type specimen of ''Steneosaurus'' was undiagnostic, and so declared the genus ''Steneosaurus'' a ''nomen dubium''. The history of this specimen has been detailed in 2017. It ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kimmeridge Bay
Kimmeridge Bay () is a bay on the Isle of Purbeck, a peninsula on the English Channel coast in Dorset, England, close to and southeast of the village of Kimmeridge, on the Smedmore Estate. The area is renowned for its fossils, with The Etches Collection in the village of Kimmeridge displaying fossils found by Steve Etches in the area over a 30-year period. It is a popular place to access the coast for tourists. To the east are the Kimmeridge Ledges, where fossils can be found in the flat clay beds. Overview Kimmeridge Bay forms part of the Jurassic Coast, a World Heritage Site. The coast is also part of a Site of Special Scientific Interest, and the whole area is part of the Dorset Area of Outstanding Natural Beauty. Kimmeridge is the type locality for Kimmeridge clay, the geological formation that covers most of the area. Within the clay are bands of bituminous shale. An oil well has operated on the shore of Kimmeridge Bay since 1959. The bay is roughly semi-circular, fac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dorset
Dorset ( ; archaically: Dorsetshire , ) is a county in South West England on the English Channel coast. The ceremonial county comprises the unitary authority areas of Bournemouth, Christchurch and Poole and Dorset (unitary authority), Dorset. Covering an area of , Dorset borders Devon to the west, Somerset to the north-west, Wiltshire to the north-east, and Hampshire to the east. The county town is Dorchester, Dorset, Dorchester, in the south. After the Local Government Act 1972, reorganisation of local government in 1974, the county border was extended eastward to incorporate the Hampshire towns of Bournemouth and Christchurch. Around half of the population lives in the South East Dorset conurbation, while the rest of the county is largely rural with a low population density. The county has a long history of human settlement stretching back to the Neolithic era. The Roman conquest of Britain, Romans conquered Dorset's indigenous Durotriges, Celtic tribe, and during the Ear ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Richard Lydekker
Richard Lydekker (; 25 July 1849 – 16 April 1915) was an English naturalist, geologist and writer of numerous books on natural history. Biography Richard Lydekker was born at Tavistock Square in London. His father was Gerard Wolfe Lydekker, a barrister-at-law with Dutch ancestry. The family moved to Harpenden Lodge soon after Richard's birth. He was educated at Trinity College, Cambridge, where he took a first-class in the Natural Science tripos (1872). In 1874 he joined the Geological Survey of India and made studies of the vertebrate palaeontology of northern India (especially Kashmir). He remained in this post until the death of his father in 1881. His main work in India was on the Siwalik palaeofauna; it was published in ''Palaeontologia Indica''. He was responsible for the cataloguing of the fossil mammals, reptiles, and birds in the Natural History Museum (10 vols., 1891). He named a variety of taxa including the golden-bellied mangabey; as a taxon authority he is nam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
