Paleontology or palaeontology is the study of prehistoric life forms on Earth through the examination of plant and animal fossils. This includes the study of body fossils, tracks (ichnites), burrows, cast-off parts, fossilised feces (coprolites), palynomorphs and chemical residues. Because humans have encountered fossils for millennia, paleontology has a long history both before and after becoming formalized as a science. This article records significant discoveries and events related to paleontology that occurred or were published in the year 1824.Angusaurus
Angusaurus is an extinct genus of trematosaurian temnospondyl within the family Trematosauridae.Bayin-Gobi Formation
The Bayin-Gobi Formation or Bayingebi Formation (simplified Chinese: 巴音戈壁组; traditional Chinese: 巴音戈壁組; pinyin: Bāyīn Gēbì Zǔ) is a geological formation in Inner Mongolia, north China, whose strata date back to the Early Cretaceous period.
Dinosaur remains are among the fossils that have been recovered from the formation.Delapparentia
Delapparentia is a genus of iguanodont dinosaur from the Early Cretaceous period of Galve, Teruel Province, Spain. It may be a synonym of Iguanodon bernissartensis.Gasosaurus
Gasosaurus (simplified Chinese: 气龙; traditional Chinese: 氣龍) () is a genus of tetanuran theropod that lived approximately 171.6 to 161.2 million years ago during the middle of the Jurassic Period. The name "Gasosaurus" is derived from the English "gasoline" and the Greek σαῦρος/sauros ("lizard / generic reptile"). Only one species is currently recognised, G. constructus, from which the specific name honours the gasoline company that found the Dashanpu fossil quarry in Sichuan Province, China, now named as the Lower Shaximiao Formation.Guegoolithus
Guegoolithus is an oogenus of fossil egg from the early Cretaceous of Spain. It is classified in the oofamily Spheroolithidae, and was probably laid by an ornithopod dinosaur.Kelmayisaurus
Kelmayisaurus is an extinct genus of carcharodontosaurid theropod dinosaur from the early Cretaceous. It was roughly 9–11 meters (30–36 feet) Its name refers to the petroleum-producing city of Karamay in the Xinjiang province of western China near where it was found.Kretzoiarctos beatrix
Kretzoiarctos beatrix is an extinct bear from the European Miocene and an ancestor of the extant giant panda.Neochoristodera
Neochoristodera is a lineage of specialised crocodile-like fully aquatic choristodere reptiles. Noted for their long jaws and large size, these animals were predominant across the northern hemisphere (and possibly Australasia), occurring in freshwater and coastal environments across the Cretaceous and early Cenozoic.Nyctiphruretidae
Nyctiphruretidae is an extinct family of hallucicranian parareptiles known from the late Early to the late Middle Permian of European Russia and south-central United States.Nyctiphruretidae was named by Michael S. Y. Lee (1997) together with the order Nyctiphruretia to include the type species Nyctiphruretus acudens known from several Middle Permian locations in European Russia. While the family was defined to be monotypic, the order was defined to include both nyctiphruretids and nycteroleterids. However, recent cladistic analyses suggest that nycteroleterids are more closely related to the Pareiasauria instead, thus making Nyctiphruretus the only genus of its order. In 2014, MacDougall & Reisz described and named a second genus of Nyctiphruretidae, Abyssomedon, from the middle Leonardian stage of the late Early Permian of Comanche County, Oklahoma, south-central United States. It contains a single species, A. williamsi, which represents the first nyctiphruretid known from North America, and the oldest species of the family.Nyctiphruretus
Nyctiphruretus (meaning "Guardian of the Night") is an extinct genus of nyctiphruretid parareptile known from the Guadalupian series (middle Permian) of European Russia.
Many fossils of the type species, N. acudens, were found well preserved near the Mezen River of European Russia in various stages of growth. The dentition identified that Nyctiphruretus is a herbivore. Based on the large numbers of individuals found and the sediment that they were found in, it appears that their diet consisted of aquatic plants. Adults discovered averaged 36 cm in length with a 4.4 cm skull that was crushed but recognisable. Nyctiphruretus was first named by Efremov in 1938 and the type species is Nyctiphruretus acudens. In 2002, a second species was named by V. V. Bulanov. N. optabilis is known from a single jaw, also from Russia, Eastern Europe.Lee (1997) named the order Nyctiphruretia and the family Nyctiphruretidae, to include Nyctiphruretus. While the family was defined to be monotypic, the order was defined to include both nyctiphruretids and nycteroleterids. However, recent cladistic analyses suggest that nycteroleterids are more closely related to the Pareiasauria instead, thus making Nyctiphruretus the only genus of its order. In 2014, MacDougall & Reisz described and named a second genus of Nyctiphruretidae, Abyssomedon, from the middle Leonardian stage of the late Early Permian of Comanche County, Oklahoma, south-central United States. It contains a single species, A. williamsi, which represents the first nyctiphruretid known from North America, and the oldest species of the family.Proplanicoxa
Proplanicoxa is a genus of iguanodont dinosaur which existed in what is now England during the Early Cretaceous period (late Barremian stage, around 126 mya).The holotype and only specimen of Proplanicoxa, BMNH R 8649, is composed of thirteen dorsals, a sacrum with ilia, parts of the pubis and ischium. The fossils were found in 1916 by Reginald Walter Hooley on the Isle of Wight from the upper Wessex Formation of England. BMNH R 8649 was originally assigned to Vectisaurus valdensis Hulke 1879 (=Mantellisaurus atherfieldensis) by Galton in 1976. The specimen was assigned to its own genus and species by Kenneth Carpenter and Yusuke Ishida in 2010, and the type species is Proplanicoxa galtoni. The generic name is derived from “before” (pro in Greek) and Planicoxa in reference to the postacetabular process of the ilium trending towards the horizontal as seen even stronger in Planicoxa, and the specific name honors Peter Galton. It may be synonymous with Mantellisaurus.Rupelo Formation
The Rupelo Formation is an Early Cretaceous (Berriasian) geologic formation in the Burgos Province of Castile and León in northern Spain. The formation crops out near the municipality Mambrillas de Lara in the northwesternmost part of the Cameros Basin in the Sierra de la Demanda.Fossil sauropod tracks have been reported from the formation. The formation was deposited under lacustrine conditions in a shallow carbonate lake, with some exposure events in the sedimentary sequence. Imprints of dinosaurs were made in carbonate mud, after they were infilled with marl. Dinosaur tracks have been assigned to sauropods, theropods and ornithopods.The municipality of Mambrillas de Lara has created a dinosaur park.Sellacoxa
Sellacoxa is a genus of iguanodont dinosaur which existed in what is now England during the Early Cretaceous period (lower Valanginian stage, around 140 mya).Identified from a nearly complete right ilium, pubis, ischium, and thirteen articulated posterior dorsals and sacrals (holotype NHMUK R.3788) found in May 1873 by John Hopkinson in the Old Roar Quarry, at Silverhill, near Hastings, from the lower Wadhurst Clay of East Sussex, England, that David Norman (2010) regarded as an individual of Barilium. It was named by Kenneth Carpenter and Yusuke Ishida in 2010 and the type species is Sellacoxa pauli. The generic name means “saddle” (sella in Latin) + “hips” (coxa) in reference to the saddle-shaped ilium, and the specific name honors Gregory S. Paul for recognising that European iguanodont diversity is higher than previously assumed.In a 2013 publication, David Norman did not consider Sellacoxa distinct from Barilium and noted that Carpenter and Ishida overlooked a left ilium, dismissing diagnostic characters of the ilium as a result of distortion.Shuangmiaosaurus
Shuangmiaosaurus is a genus of herbivorous ornithischian dinosaur which lived during the late Albian age of the Early Cretaceous Period, about 100 million years ago. It was an iguanodont euornithopod which lived in China.
The type species, Shuangmiaosaurus gilmorei, was named and described by You Hailu, Ji Qiang Li Jinglu and Li Yinxian in 2003. The generic name refers to the village of Shuangmiao in Beipiao in Liaoning Province, the site of the discovery. The specific name honours the American paleontologist Charles Whitney Gilmore.The holotype, specimen LPM 0165, was found in the Sunjiawan Formation, originally seen as dating to the Late Cretaceous (Cenomanian to Turonian) but today considered to have been somewhat older. It consists of a partial left upper jaw and lower jaw, including the maxilla, part of the praemaxilla, elements of the lacrimal and the dentary.
Shuangmiaosaurus was a rather large euornithopod. In 2010 Gregory S. Paul estimated its length at 7.5 metres, its weight at 2.5 tonnes.Shuangmiaosaurus was originally considered a basal member of the Hadrosauroidea, one closely related to the Hadrosauridae. Subsequent authors, including David B. Norman of Cambridge University, consider it a more basal member of the Iguanodontia outside of the Hadrosauroidea.Simoedosaurus
Simoedosaurus is an extinct reptile known from the Paleocene of North America, Europe and western Asia, and a member of the Choristodera, a group of aquatic reptiles that lived in the Northern Hemisphere from the Jurassic to the early Cenozoic.Szechuanosaurus
Szechuanosaurus ("Szechuan lizard") is an extinct genus of carnivorous theropod dinosaur from the Late Jurassic. Fossils referred to the genus have been found in China, Asia in the Oxfordian (Peng et al., 2005). Its type species is largely based on several undiagnostic teeth from the Shangshaximiao Formation.Theiophytalia
Theiophytalia is a genus of herbivorous iguanodontian dinosaur from the lower Cretaceous period (Aptian-Albian stage, about 112 million years ago) of Colorado, USA.Xinjiangchelyidae
Xinjiangchelyidae is an extinct family of Cryptodira turtles found in Asia and western Europe.
