Suchosaurus is a spinosaurid dinosaur from Cretaceous England and Portugal, originally believed to be a genus of crocodile. The type material, consisting of teeth, was used by British palaeontologist Richard Owen to name the species S. cultridens in 1841. Later in 1897, French palaeontologist Henri-Émile Sauvage named a second species, S. girardi, based on two fragments from the mandible and one tooth discovered in Portugal. Suchosaurus is possibly a senior synonym of the contemporary spinosaurid Baryonyx, but is usually considered a dubious name due to the paucity of its remains, and is considered an indeterminate baryonychine. In the Wadhurst Clay Formation of what is now southern England, Suchosaurus lived alongside other dinosaurs, as well as plesiosaurs, mammals, and crocodyliforms.
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 1994.

The Marnes de Dives is a geological formation in Normandy, France. It dates back to the upper part of the Callovian stage of the Middle Jurassic. And is partially equivalent to the Oxford Clay in England. It predominantly consists of ooidal marl, rich in pyrite and lignite, interbedded with thin limestone horizons. It is best exposed at the base of the Falaises des Vaches Noires as well as the foreshore at low tide. It is known for its fossils, notably those of ammonites, marine crocodiles and fragmentary remains of dinosaurs, mostly theropods.
The Tiourarén Formation is a geological formation in the Agadez Region of Niger whose strata were originally thought to be Early Cretaceous. However, re-interpretation of the sediments showed that they are probably Middle or Late Jurassic (Bathonian-Oxfordian) in age. Other works suggested it reaches the Barremian. It is the uppermost unit of the Irhazer Group. Dinosaur remains & other vertebrates are among the fossils that have been recovered from the formation. Originally part of the "Argiles de l'Ihrazer", the Tiouaren Formation primarily comprises reddish to purple siltstones with occasional marls, limestones, and scarce channel sandstones.
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 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.
The Caranguejeira Conglomerate is an Aptian to Cenomanian geologic formation in Portugal. Dinosaur remains diagnostic to the genus level are among the fossils that have been recovered from the formation.
The Moreno Formation is a Mesozoic geologic formation located in San Joaquin Valley (California).
Dinosaur remains diagnostic to the genus level are among the fossils that have been recovered from the formation.
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 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.
The Irhazer Shale or Irhazer II Formation is a Middle Jurassic geologic formation of the Irhazer Group in the Agadez Region of Niger. Fossil ornithopod tracks have been reported from the formation. The dinosaur Spinophorosaurus is known from the formation.
The following outline is provided as an overview of and topical guide to dinosaurs:
Somalirhynchia africana is a species of extinct, medium-sized brachiopod, a marine rhynchonellate lampshell in the family Tetrarhynchiidae. It is roughly the size and shape of a 1-inch (25 mm) toy marble, and has about 29 ribs fanning out from the hinge.
The Bull Run Formation is a Late Triassic (Norian) stratigraphic unit in the eastern United States. Fossil fish bones and scales have been found in outcrops of the formation's Groveton Member in Manassas National Battlefield Park. Indeterminate fossil ornithischian tracks have been reported from the formation.
The De Queen Formation, formerly known as the DeQueen Limestone Member is a Mesozoic geological formation located in southwestern Arkansas and southeastern Oklahoma in the United States. Fossil sauropod and theropod tracks have been reported from the formation. It preserves fossils dating back to the Cretaceous period, particularly the Albian age.
The La Casita Formation is a geologic formation in Mexico. It preserves fossils dating back to the Kimmeridgian to lowermost Berriasian. It is laterally equivalent to the La Caja Formation and the Pimienta Formation. The ichthyosaurs Jabalisaurus and Acuetzpalin are known from the formation, as well as the metriorhynchid Dakosaurus and indeterminate pliosaurs.
This list of dinosaur-bearing rock formations is a list of geologic formations in which dinosaur fossils have been documented.
The Bulldog Shale is a formation of Early Cretaceous age that forms part of the Marree Subgroup of the Rolling Downs Group, located in the Eromanga Basin of South Australia, Queensland and New South Wales.
