Argentinosaurus is a genus of giant sauropod dinosaur that lived during the Late Cretaceous period in what is now Argentina. Although it is only known from fragmentary remains, Argentinosaurus is one of the largest known land animals of all time, perhaps the largest, measuring 30–35 metres (98–115 ft) long and weighing 65–80 tonnes. It was a member of Titanosauria, the dominant group of sauropods during the Cretaceous. It is widely regarded by many paleontologists as the biggest dinosaur ever, and perhaps lengthwise the longest animal ever, though both claims have no concrete evidence yet.
Mamenchisaurus is a genus of sauropod dinosaur known for their remarkably long necks which made up nearly half the total body length. Numerous species have been assigned to the genus; however, many of these might be questionable. Fossils have been found in the Sichuan Basin and Yunnan Province in China. Several species are from the Upper Shaximiao Formation whose geologic age is uncertain. However, evidence suggests that this be no earlier than the Oxfordian stage of the Late Jurassic. M. sinocanadorum dates to the Oxfordian stage and M. anyuensis to the Aptian stage of the Early Cretaceous around 114.4 mya. Most species were medium to large size sauropods, around 15 to 26 meters in length and possibly up to 35 meters (115 ft) based on two undescribed vertebrae.
Giganotosaurus is a genus of theropod dinosaur that lived in what is now Argentina, during the early Cenomanian age of the Late Cretaceous period, approximately 99.6 to 95 million years ago. The holotype specimen was discovered in the Candeleros Formation of Patagonia in 1993 and is almost 70% complete. The animal was named Giganotosaurus carolinii in 1995; the genus name translates to "giant southern lizard", and the specific name honors the discoverer, Rubén D. Carolini. A dentary bone, a tooth, and some tracks, discovered before the holotype, were later assigned to this animal. The genus attracted much interest and became part of a scientific debate about the maximum sizes of theropod dinosaurs.
Carcharodontosaurus is a genus of carnivorous theropod dinosaur that lived in North Africa from about 99 to 94 million years ago during the Albian and Cenomanian stages of the Late Cretaceous. Fossils of the genus were first described from Algeria by French paleontologists Charles Depéret and Justin Savornin as Megalosaurus saharicus. However, these fossils have since been lost and were too fragmentary to constitute a valid new species. Many additional remains were collected by crews of German paleontologist Ernst Stromer during a 1914 expedition to Egypt. Stromer did not report this discovery until 1931, in which he dubbed the novel genus Carcharodontosaurus, making the type species C. saharicus. Unfortunately, this specimen was destroyed during the Second World War. In 1996 a nearly complete skull of C. saharicus was found in the Kem Kem Beds of Morocco, the first well-preserved specimen to be found in almost a century, and designated the neotype. Another species was unearthed in sediments from the Echkar Formation of northern Niger. It was named C. iguidensis in 2007.
Suchomimus is a genus of spinosaurid dinosaur that lived between 125 and 112 million years ago in what is now Niger, West Africa, during the Aptian to early Albian stages of the Early Cretaceous period. It was named and described by paleontologist Paul Sereno and colleagues in 1998, based on a partial skeleton from the Elrhaz Formation. Suchomimus's long and shallow skull, similar to that of a crocodile, earns it its generic name, while the specific name Suchomimus tenerensis alludes to the locality of its first remains, the Ténéré Desert.
Euhelopus is a genus of sauropod dinosaur that lived between 145 and 133 million years ago during the Berriasian and Valanginian stages of the Early Cretaceous in what is now Shandong Province in China. It was a large quadrupedal herbivore. Like sauropods such as brachiosaurs and titanosaurs, Euhelopus had longer forelegs than hind legs. This discovery was paleontologically significant because it represented the first dinosaur scientifically investigated from China: seen in 1913, rediscovered in 1922, and excavated in 1923 and studied by T'an during the same year. Unlike most sauropod specimens, it has a relatively complete skull.
Huabeisaurus was a genus of dinosaur from the Late Cretaceous. It was a sauropod which lived in what is present-day northern China. The type species, Huabeisaurus allocotus, was first described by Pang Qiqing and Cheng Zhengwu in 2000. Huabeisaurus is known from numerous remains found in the 1990s, which include teeth, partial limbs and vertebrae. Due to its relative completeness, Huabeisaurus represents a significant taxon for understanding sauropod evolution in Asia. Huabeisaurus comes from Kangdailiang and Houyu, Zhaojiagou Town, Tianzhen County, Shanxi province, China. The holotype was found in the unnamed upper member of the Huiquanpu Formation, which is Late Cretaceous (?Cenomanian–?Campanian) in age based on ostracods, charophytes, and fission-track dating.
Pellegrinisaurus is a genus of titanosaurian sauropod dinosaur that lived in South America during the Late Cretaceous period. The holotype was found in the Allen Formation, Argentina.
Hexing is an extinct genus of basal ornithomimosaur dinosaur known from the Early Cretaceous of northeastern China. It contains a single species, Hexing qingyi.
Nankangia is an extinct genus of caenagnathoid oviraptorosaurian dinosaur known from the Upper Cretaceous Nanxiong Formation of Nankang County, Ganzhou City of Jiangxi Province, southeastern China. It contains a single species, Nankangia jiangxiensis. N. jiangxiensis coexisted with at least four other caenagnathoids, including but not limited to Corythoraptor, Banji long, Ganzhousaurus nankangensis and Jiangxisaurus ganzhouensis. The relatively short dentary and non-downturned mandibular symphysis of Nankangia suggest that it may have been more herbivorous than carnivorous. Its diet consisted of leaves and seeds.
This glossary explains technical terms commonly employed in the description of dinosaur body fossils. Besides dinosaur-specific terms, it covers terms with wider usage, when these are of central importance in the study of dinosaurs or when their discussion in the context of dinosaurs is beneficial. The glossary does not cover ichnological and bone histological terms, nor does it cover measurements.
Sarmientosaurus is a genus of titanosaurian sauropod dinosaur belonging to the Titanosauria. It lived in what is now South America, specifically Argentina, during the Upper Cretaceous Period about 95 million years ago. The type species is Sarmientosaurus musacchioi.
Magnamanus is an extinct genus of herbivorous iguanodontian dinosaur that lived during the Early Cretaceous in what is now Spain in the Golmayo Formation. It contains a single species, Magnamanus soriaensis.
Shingopana is a genus of titanosaurian sauropod from the Upper Cretaceous Galula Formation of Tanzania. It is known from only the type species, S. songwensis. Gorscak & O'Connor's phylogenetic testing suggest Shingopana is more closely related to the South American titanosaur family of Aeolosaurini than any of the titanosaurs found so far in North & South Africa.
Hesham Sallam is an Egyptian paleontologist and the founder of the Mansoura University Vertebrate Paleontology Center (MUVP-C), the first vertebrate paleontology program in the Middle East. He works as an associate professor at the American University in Cairo and Mansoura University. Sallam led the discovery and description of Mansourasaurus shahinae, a species of sauropod dinosaur from Egypt, which has improved understanding of the prehistory of Africa during the latest Cretaceous period. His work has helped popularize paleontology in Egypt.
The Quseir Formation is a geological formation in the vicinity of the Kharga Oasis in Egypt. It is Campanian In age. The lithology largely consists of soft shale with hard bands of sandstone, siltstone and phosphorite. The environment of deposition was nearshore to freshwater fluvio-lacustrine characterized by moist and aquatic habitats with a tropical warm-humid climate. It is conformably overlain by the marine late Campanian-Maastrichtian Duwi Formation, and unconformably overlies the Turonian Taref Formation. The sauropod dinosaur Mansourasaurus is known from the formation, as well as the proximal fibula of an indeterminate theropod. Additionally the lungfish genera Lavocatodus and Protopterus, the crocodyliform Wahasuchus and the bothremydid turtle Khargachelys are also known.
Mnyamawamtuka is a genus of lithostrotian titanosaur sauropod dinosaur from the Cretaceous Galula Formation in Tanzania. The type and only species is M. moyowamkia.
Abditosaurus is an extinct genus of titanosaurian sauropod dinosaur from the Late Cretaceous (Maastrichtian) Tremp Group of Catalonia, Spain. The type and only species is Abditosaurus kuehnei. Phylogenetic analyses recover it within a clade of South American and African saltasaurines, distinct from other insular dwarf sauropods from the European archipelago. Abditosaurus inhabited the Ibero-Armorican Island, a prehistoric island made up of what is now Spain, Portugal, and southern France, and would have been the largest titanosaur species in its environment.
IberospinusIPA: [aɪbiːʌroʊs̠piːnʊs̠] or IPA: [aɪbiːʌroʊs̠paɪnʌs̠] is an extinct genus of spinosaurid dinosaur from the Early Cretaceous (Barremian) Papo Seco Formation of Portugal. The genus contains a single species, I. natarioi, known from several assorted bones belonging to one individual. Iberospinus represents one of four known spinosaurid taxa from the Iberian Peninsula, the others being Vallibonavenatrix, Camarillasaurus and Protathlitis. It is important for its implications of the geographical origin of Spinosauridae and the suggested presence of an at least semi-aquatic lifestyle early in the evolution of this clade.
Ruixinia is an extinct genus of somphospondylan titanosauriform dinosaur from the Early Cretaceous (Barremian) Yixian Formation of China. The genus contains a single species, Ruixinia zhangi. The Ruixinia holotype is a partial articulated skeleton with the most complete series of caudal vertebrae known from any Asian titanosauriform.
