Acynodon

  1. Acynodon adriaticus
  2. Acynodon iberoccitanus
Early Campanian - Late Maastrichtian 83.5–66 Ma Italy Initially placed within Alligatoridae but has since been reclassified as a more basal globidontan, the oldest and most primitive known to date. Recent studies have since resolved Acynodon as a basal eusuchian crocodylomorph, outside of the Crocodylia crown group, and a close relative to Hylaeochampsa.

  2. Allodaposuchus iberoarmoricanus
84.9–66.043 Ma Spain and France, A genus of average-sized basal eusuchian, growing to around 3 m (9.8 ft) long. The main feature that distinguishes this species from other related crocodylomorphs is the orientation of a groove at the back of the skull called the cranioquadrate passage; unlike the cranioquadrate passages of other crocodylomorphs, which are only visible at the back of the skull, the cranioquadrate passage of this variety is visible when the skull is viewed from the side.

†Dinosaurs

edit

During the Campanian age, a radiation among dinosaur species occurred. In North America, for example, the number of known dinosaur genera rises from 4 at the base of the Campanian to 48 in the upper part. This development is sometimes referred to as the "Campanian Explosion". However, it is not yet clear if the event is artificial, i.e. the low number of genera in the lower Campanian can be caused by a lower preservation chance for fossils in deposits of that age. The generally warm climates and large continental area covered in shallow sea during the Campanian probably favoured the dinosaurs. In the following Maastrichtian stage, the number of North American dinosaur genera found is 30% less than in the upper Campanian.[1]

81 mya Seonso Conglomerate, Boseong, Korean Peninsula Koreanosaurus is likely a burrowing dinosaur. Unlike its orodromine relatives, Koreanosaurus is assumed to have been a quadruped. It reached 2–2.4 meters in body length.

Orodromeus

76.7 mya Montana, USA Orodromeus was a small fast bipedal herbivore that probably coexisted with dinosaurs such as Daspletosaurus and Einiosaurus. Its length was estimated by Horner & Weishampel at 2.5 metres.

74 mya Kirtland Formation, Texas A saurolophine hadrosaur.

Angulomastacator

76.9 mya Aguja Formation, Texas A lambeosaurine.

Aquilarhinus

Aguja Formation, Texas Formerly referred to Kritosaurus and Gryposaurus it might be a much more basal hadrosaurid.

Aralosaurus

Upper Santonian-Lower Campanian boundary 85.8 mya Bostobe Formation, Kazakhstan A basal lambeosaurine hadrosaur, Aralosaurus was about the size of an elephant. Although very little is known about Aralosaurus (only one near complete skull has been found); it was identified by a beak with nearly 1,000 small teeth in 30 rows. The back of an Aralosaurus skull was wide, a feature suggestive of large jaw muscles used to power its chewing apparatus.

Brachylophosaurus

76.5 mya Montana, USA; Alberta, Canada Brachylophosaurus was a basal saurolophine hadrosaur which reached an adult length of 9 meters (30 feet).

Corythosaurus

77-76.5 mya Alberta, Canada A derived lambeosaurine. Corythosaurus weighed in at 4 tonnes and measured roughly 10 metres (33 feet) from nose to tail.

Diclonius

75 mya Montana, USA A dubious genus of hadrosaur known only from dental fossils.

Edmontosaurus

73.0-76.5 mya Canada Edmontosaurus, a saurolophine hadrosaur, included some of the largest ornithischian species, measuring up to 12 metres (39 feet) long and weighing around 4.0 metric tons (4.4 short tons).

Gasparinisaura

85 mya Argentina Gasparinisaura was a small ornithopod of the basal clade Elasmaria. In 2010 Gregory S. Paul estimated the length at 1.7 metres, the weight at thirteen kilogrammes.

Gilmoreosaurus

72 mya Mongolia A relatively large hadrosauromorph.

Gryposaurus

83-75.5 mya Alberta, Canada Gryposaurus was a saurolophine hadrosaur of typical size and shape.

Hadrosaurus

79.5 mya New Jersey, USA One of the most basal hadrosaurids and the namesake genus of the family. It was likely bipedal for the purposes of running, but could use its forelegs to support itself while feeding.

Hypacrosaurus

75-67 mya Alberta, Canada A derived lambeosaurine, Hypacrosaurus is most easily distinguished from other hollow-crested duckbills by its tall neural spines and the form of its crest. The neural spines, which project from the top of the vertebrae, are 5 to 7 times the height of the body of their respective vertebrae in the back,[4] which would have given it a tall back in profile. The skull's hollow crest is like that of Corythosaurus, but is more pointed along its top, not as tall, wider side to side, and has a small bony point at the rear

Hypsibema

North Carolina and Missouri, USA A large hadrosauroid known only by a couple of vertebrae.

Kritosaurus

73 mya North America The type specimen of Kritosaurus navajovius is only represented by a partial skull and lower jaws, and associated postcranial remains.

Lambeosaurus

76-75 mya Alberta, Canada A derived lambeosaurine hadrosaur, namesake genus of the subfamily.

Lophorhothon

80 mya Alabama, USA A genus of hadrosauromorphs.

Malefica

Aguja Formation, Texas A basal hadrosaur.

Maiasaura

76.7 mya Montana, USA Maiasaura was a large basal saurolophine hadrosaur, attaining an adult length of about 9 metres (30 feet) and had the typical hadrosaurid flat beak and a thick nose. It had a small, spiky crest in front of its eyes. The crest may have been used in headbutting contests between males during the breeding season.

Matheronodon

Late Campanian, 74–72 mya Grès à Reptiles Formation, France. A rhabdodontid.

Microhadrosaurus

China A possibly dubious genus of hadrosaur known by a partial lower jaw from a juvenile.

Mochlodon

Austria A rhabdodontid.

Naashoibitosaurus

73 mya New Mexico, USA Naashoibitosaurus, a saurolophine hadrosaur, based as it is on a single partial skeleton, is not well known in terms of anatomy. Its skull, the most thoroughly described portion, has a low nasal crest that peaks in front of the eyes, but does not strongly arch as in Gryposaurus.

Nipponosaurus

80 mya Sakhalin island A lambeosaurine hadrosaur known from subadult remains.

Ornatops

78 mya New Mexico, USA A genus of basal saurolophine hadrosaur.

Parasaurolophus

76.5-73 mya Alberta, Canada; New Mexico and Utah, USA A large derived lambeosaurine hadrosaur.

Probrachylophosaurus

79 mya Montana, USA; Alberta, Canada A large basal saurolophine hadrosaur which reached an adult length of over 9 meters (30 feet).

Prosaurolophus

76-75 mya Alberta, Canada Prosaurolophus was a large-headed duckbill; the most complete described specimen has a skull around 0.9 meters (3.0 feet) long on a ~8.5 meter long skeleton (~28 ft).[2] It had a small, stout, triangular crest in front of the eyes; the sides of this crest were concave, forming depressions. The upper arm was relatively short.

Pteropelyx

75 mya Montana, USA A dubious genus of lambeosaurine hadrosaurs. Historically, several species were assigned to it, all based on extremely fragmentary remains, but there is no evidence to support these assignments.

Rhabdodon

72 mya France; Spain; Haţeg Island, Romania It is unclear whether it was an iguanodont or a hypsilophodont, and may be a "missing link" between the two. Current evidence indicates it is an iguanodont similar to Tenontosaurus.

Saurolophus

69.5-68.5 mya North America, Asia Saurolophus is known from material including nearly complete skeletons, giving researchers a clear picture of its bony anatomy. S. osborni, the rarer Albertan species, was around 9.8 meters (32 feet) long, with its skull a meter long (3.3 feet). Its weight is estimated at 1.9 tonnes (2.1 tons). S. angustirostris, the Mongolian species, was larger; the type skeleton is roughly 12 meters (39 feet) long, and larger remains are reported.

Sektensaurus

~76–72 mya Lago Colhué Huapí Formation, Golfo San Jorge Basin, Patagonia, Argentina A genus of ornithopod dinosaur, possibly an elasmarian. Sektensaurus is the first known non-hadrosauroid ornithopod of central Patagonia.

Shantungosaurus

72 mya China A very large saurolophine hadrosaur closely related to Edmontosaurus, it is one of the longest and largest known hadrosaurids and possibly the largest non-sauropod dinosaur; the composite skeleton of a medium-sized individual mounted at the Geological Institute of China in Beijing measures 14.72 metres (48.3 feet) in length.

Stephanosaurus

76–75 mya Dinosaur Park Formation, Alberta A dubious genus of hadrosaurid dinosaur with a complicated taxonomic history.

72–71 mya China A genus of hadrosauromorph dinosaur.
