Baryonychine
Baryonychinae is an extinct clade or subfamily of spinosaurids from the Early Cretaceous (Valanginian-Albian) of Britain, Portugal, and Niger. In 2021, it consisted of six genera: ''Ceratosuchops'', ''Cristatusaurus'', ''Riparovenator'', ''Suchomimus'', '' Suchosaurus'', and ''Baryonyx'', the nominal genus. The clade was named by Charig & Milner in 1986 and defined by Sereno ''et al''. in 1998 and Holtz ''et al.'' in 2004 as all taxa more closely related to ''Baryonyx walkeri'' than to ''Spinosaurus aegyptiacus''. Baryonychines were large, bipedal predators with elongated, crocodile-like skulls and lower jaw tips fanning out into rosettes bearing conical, often unserrated, teeth, and a distinct premaxillary notch. They possessed robust forelimbs supporting three-fingered hands with an enlarged first digit claw, to which the subfamily name indirectly refers. Members of this group, unlike the more derived Spinosaurinae, sported only low sails or none at all. History of discovery ...

Spinosaurid
The Spinosauridae (or spinosaurids) are a clade or family of tetanuran theropod dinosaurs comprising ten to seventeen known genera. They came into prominence during the Cretaceous period. Spinosaurid fossils have been recovered worldwide, including Africa, Europe, South America and Asia. Their remains have generally been attributed to the Early to Mid Cretaceous. Spinosaurids were large bipedal carnivores. Their crocodilian-like skulls were long, low and narrow, bearing conical teeth with reduced or absent serrations. The tips of their upper and lower jaws fanned out into a spoon-shaped structure similar to a rosette, behind which there was a notch in the upper jaw that the expanded tip of the lower jaw fit into. The nostrils of spinosaurids were retracted to a position further back on the head than in most other theropods, and they had bony crests on their heads along the midline of their skulls. Their robust shoulders wielded stocky forelimbs, with three-fingered hands that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Baryonyx
''Baryonyx'' () is a genus of theropod dinosaur which lived in the Barremian stage of the Early Cretaceous period, about 130–125 million years ago. The first skeleton was discovered in 1983 in the Smokejack Clay Pit, of Surrey, England, in sediments of the Weald Clay Formation, and became the holotype specimen of ''Baryonyx walkeri'', named by palaeontologists Alan J. Charig and Angela C. Milner in 1986. The generic name, ''Baryonyx'', means "heavy claw" and alludes to the animal's very large claw on the first finger; the specific name, ''walkeri'', refers to its discoverer, amateur fossil collector William J. Walker. The holotype specimen is one of the most complete theropod skeletons from the UK (and remains the most complete Spinosaurid), and its discovery attracted media attention. Specimens later discovered in other parts of the United Kingdom and Iberia have also been assigned to the genus, though many have since been moved to new genera. The holotype specimen, whic ...

Suchomimus
''Suchomimus'' (meaning "crocodile mimic") is a genus of spinosaurid dinosaur that lived between 125 and 112 million years ago in what is now Niger, during the Aptian to early Albian stages of the Early Cretaceous period. It was named and described by palaeontologist 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. ''Suchomimus'' was a relatively large theropod, reaching in length and weighing . However, the age of the holotype specimen is uncertain, so it is unclear whether this size estimate would have been its maximum. The narrow skull of ''Suchomimus'' was perched on a short neck, and its forelimbs were powerfully built, bearing a giant claw on each thumb. Along the midline of the animal's back ran a low dorsal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vallibonavenatrix
''Vallibonavenatrix'' (meaning "Vallibona huntress" after the town near where its remains were found) is a genus of spinosaurid dinosaur from the Early Cretaceous (Barremian) Arcillas de Morella Formation of Castellón, Spain. The type and only species is ''Vallibonavenatrix cani'', known from a partial skeleton. Discovery and naming During the late 1980s and early 1990s, amateur fossil collector Juan Cano Forner was recovering bones from various localities in Els Ports Natural Park, located in the Province of Castellón, Spain. In one of these—the Santa Águeda locality in the town of Vallibona—he excavated numerous vertebrate remains dating to the Mesozoic era, among which were dinosaur fossils. Forner housed these fossils in a private collection at Sant Mateu, which the Generalitat Valenciana acknowledged as a museographic collection in 1994. In 2007, the Spanish palaeontologist Fernando Gómez-Fernández and colleagues published a provisional description on the pel ...

Suchosaurus Girardi
''Suchosaurus'' (meaning "crocodile lizard") 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. History of discovery In about 1820, British palaeontologist Gideon Mantell acquired teeth discovered near Cuckfield in the Wadhurst Cla ...

Cristatusaurus
''Cristatusaurus'' is a genus of theropod dinosaur that lived during the Early Cretaceous Period of what is now Niger, 112 million years ago. It was a baryonychine member of the Spinosauridae, a group of large bipedal carnivores with well-built forelimbs and elongated, crocodile-like skulls. The type species ''Cristatusaurus lapparenti'' was named in 1998 by scientists Philippe Taquet and Dale Russell, on the basis of jaw bones and some vertebrae. Two claw fossils were also later assigned to ''Cristatusaurus''. The animal's generic name, which means "crested reptile", alludes to a sagittal crest on top of its snout; while the specific name is in honor of the French paleontologist Albert-Félix de Lapparent. ''Cristatusaurus'' is known from the Albian to Aptian Elrhaz Formation, where it would have coexisted with sauropod and iguanodontian dinosaurs, other theropods, and various crocodylomorphs. Originally proposed to be an indeterminate species of ''Baryonyx'', the identity of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Riparovenator
''Riparovenator'' ("riverbank hunter") is a genus of baryonychine spinosaurid dinosaur from the Early Cretaceous (Barremian) period of Britain, the type species is ''Riparovenator milnerae''. Discovery and naming Between 2013 and 2017, spinosaurid fossils were uncovered at the beach near the Chilton Chine before being brought to Dinosaur Isle. Such remains had been generally referred to ''Baryonyx'' but were understood recently to represent two species new to science. In 2021, the type species ''Riparovenator milnerae'' was named and described by a team of palaeontologists including Chris T. Barker, David William Elliot Hone, Darren Naish, Andrea Cau, Jeremy A.F. Lockwood, Brian Foster, Claire E. Clarkin, Philipp Schneider and Neil John Gostling. The generic name is derived from the Latin ''rīpārius'', "of the river bank", and ''vēnātor'', "hunter". The specific name honors Angela Milner, deceased in August 2021. The holotype remains of this taxon consist of IWCMS ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Spinosaurus Aegyptiacus
''Spinosaurus'' (; ) is a genus of spinosaurid dinosaur that lived in what now is North Africa during the Cenomanian to upper Turonian stages of the Late Cretaceous period, about 99 to 93.5 million years ago. The genus was known first from Egyptian remains discovered in 1912 and described by German palaeontologist Ernst Stromer in 1915. The original remains were destroyed in World War II, but additional material came to light in the early 21st century. It is unclear whether one or two species are represented in the fossils reported in the scientific literature. The best known species is ''S. aegyptiacus'' from Egypt, although a potential second species, ''S. maroccanus'', has been recovered from Morocco. The contemporary spinosaurid genus ''Sigilmassasaurus'' has also been synonymized by some authors with ''S. aegyptiacus'', though other researchers propose it to be a distinct taxon. Another possible junior synonym is ''Oxalaia'' from the Alcântara Formation in Brazil. ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
