Albian dinosaurs

Deinonychus ( ; ) is a genus of dromaeosaurid theropod dinosaur with one described species, Deinonychus antirrhopus. This species, which could grow up to long, lived during the Early and Late Cretaceous Period, about 115–93.9 million years ago (from the mid-Aptian to Cenomanian stages). Fossils have been recovered from the U.S. states of Montana, Utah, Wyoming, and Oklahoma, in rocks of the Cloverly Formation and Antlers Formation, though teeth that may belong to Deinonychus have been found much farther east in Maryland.

Acrocanthosaurus ( ; ) is a genus of carcharodontosaurid dinosaurs that existed in what is now North America during the Barremian and early Cenomanian stages of the Early Cretaceous and Late Cretaceous, from 125 to 99.6 million years ago. Like most dinosaur genera, Acrocanthosaurus contains only a single species, A. atokensis. It had a continent-wide range, with fossil remains known from the U.S. states of Oklahoma, Texas, and Wyoming in the west and Maryland in the east. However, most of these remains are assigned to the species based on the assumption that Acrocanthosaurus is the only large

Suchomimus is a genus of large theropod dinosaur that lived in what is now Niger during the Aptian to Albian stages of the Early Cretaceous period, 112 million years ago. The only known species is S. tenerensis, originally described in 1998 by paleontologist Paul Sereno and colleagues from several fossils discovered one year earlier in the Elrhaz Formation. Although these fossils come from multiple specimens, they represent one of the most anatomically well-documented spinosaurids. The animal's generic name, which means "crocodile mimic", alludes to its elongated skull and piscivorous adaptati

Irritator is a genus of spinosaurid dinosaur that lived in what is now Brazil during the Albian stage of the Early Cretaceous Period, about 113 to 110 million years ago. It is known from a nearly complete skull found in the Romualdo Formation of the Araripe Basin. Fossil dealers had acquired this skull and sold it to the State Museum of Natural History Stuttgart. In 1996, the specimen became the holotype of the type species Irritator challengeri. The genus name comes from the word "irritation", reflecting the feelings of paleontologists who found the skull had been heavily damaged and altered

Leaellynasaura (meaning "Leaellyn's lizard") is a genus of small herbivorous ornithischian dinosaurs from the late Aptian to early Albian stage of the Early Cretaceous, around 118-110 million years ago. It was first discovered in Dinosaur Cove, Australia. The only known species is Leaellynasaura amicagraphica. It was described in 1989, and named after Leaellyn Rich, the daughter of the Australian palaeontologist couple Tom Rich and Patricia Vickers-Rich who discovered it. The specific name, amicagraphica, translates to "friend writing" and honours both the Friends of the Museum of Victoria and

Acanthopholis (; meaning "spiny scales") is a genus of ankylosaurian dinosaur in the family Nodosauridae that lived during the Late Cretaceous Period of England. A single species, A. horrida, exists.

Tenontosaurus ( ; ) is a genus of iguanodontian ornithopod dinosaur. It had an unusually long, broad tail, which like its back was stiffened with a network of bony tendons. The genus is known from the late Aptian to Albian ages of the Early Cretaceous period sediments of western North America, dating between 115 and 108 million years ago. It contains two species, Tenontosaurus tilletti (described by John Ostrom in 1970) and Tenontosaurus dossi (described by Winkler, Murry, and Jacobs in 1997). Many specimens of T. tilletti have been collected from several geological formations throughout

Nigersaurus () is a genus of rebbachisaurid sauropod dinosaur that lived during the middle Cretaceous period, about 115 to 105 million years ago. It was discovered in the Elrhaz Formation in an area called Gadoufaoua, in Niger. Fossils of this dinosaur were first described in 1976, but it was only named Nigersaurus taqueti in 1999 after further and more complete remains were found and described. The genus name means "Niger reptile", and the specific name honours the palaeontologist Philippe Taquet, who discovered the first remains.

Muttaburrasaurus was a genus of herbivorous iguanodontian ornithopod dinosaur that lived in what is now north-eastern Australia sometime between 112 and 103 million years ago during the early Cretaceous period. It has been recovered in some analyses as a member of the iguanodontian clade Rhabdodontomorpha, or alternately as a member of Elasmaria. After Kunbarrasaurus, it is Australia's most completely known dinosaur from skeletal remains. It was named after Muttaburra, the site in Queensland, Australia, where it was found. The dinosaur was selected from twelve candidates to become the official

Agustinia () is a genus of sauropod dinosaur from the Early Cretaceous of South America. The genus contains a single species, A. ligabuei, known from a single specimen that was recovered from the Lohan Cura Formation of Neuquén Province in Argentina. It lived about 116–108 million years ago, in the Aptian–Albian stages of the Early Cretaceous Period.

Tyrannotitan (; ) is a genus of large theropod dinosaur belonging to the carcharodontosaurid family. It is known from a single species, T. chubutensis, which lived during the Albian stage of the Early Cretaceous period in what is now Argentina. Tyrannotitan is considered to share a close relationship with other prominent South American carcharodontosaurids such as Giganotosaurus and Mapusaurus. Unlike its relatives, it was bulkier and more robust. This taxon is known from two specimens, both of which are highly incomplete.

Alxasaurus (; meaning "Alxa lizard") is a genus of therizinosauroid theropod dinosaurs from the Early Cretaceous (Albian age) Bayin-Gobi Formation of Inner Mongolia. It is known from five specimens, recovered from the Bayin-Gobi in 1988, as part of the China-Canada Dinosaur Project. During their preparation, palaeontologists Dong Zhiming and Dale Russell noted strong similarities to Segnosaurus. In 1993, they described Alxasaurus and named its type species, A. elesitaiensis. While therizinosaurs had previously been tentatively seen as late-surviving basal sauropodomorphs, the description of Al

Atlascopcosaurus () is a genus of herbivorous basal iguanodont dinosaur from the Early Cretaceous Eumeralla Formation of Australia.

Scipionyx ( ) was a genus of theropod dinosaur from the Early Cretaceous Pietraroja Formation of Italy, around 113 million years ago.

Ultrasaurus (meaning "ultra lizard") is a genus of sauropod dinosaur discovered by Haang Mook Kim in South Korea. However, the name was first used unofficially (as a nomen nudum) in 1979 by Jim Jensen to describe a set of giant dinosaur bones he discovered in the United States. Because Kim published the name for his specimen before Jensen could do so officially, George Olshevsky renamed the specimen as Ultrasauros. Jensen's giant sauropod was later found to be a chimera, and the type remains are now assigned to Supersaurus.

Harpymimus is a genus of basal ornithomimosaurian theropod dinosaur from the Early Cretaceous Period of what is now Mongolia. Unlike later, more derived ornithomimosaurs, Harpymimus still possessed teeth, although they appear to have been restricted to the dentary of the lower jaw.

thumb|Astrodon holotype tooth Astrodon is a genus of large herbivorous sauropod dinosaur, measuring in length, in height and in body mass. It lived in what is now the eastern United States during the Early Cretaceous period, and fossils have been found in the Arundel Formation, which has been dated through palynomorphs to the Albian about 112 to 110 million years ago.

Kryptops (meaning "covered face") is an extinct genus of possibly chimeric abelisaurid theropod dinosaurs from the Early Cretaceous of Niger. It is known from a partial maxilla (upper jaw bone) found at the Gadoufaoua locality in the western Ténéré Desert, in rocks of the Aptian–Albian-age Elrhaz Formation. The fossils were collected in 2000 by a University of Chicago expedition to Niger led by American paleontologist Paul Sereno. They were then described in 2008 by Sereno and Steve Brusatte. The genus contains a single species, Kryptops palaios. Sereno and Brusatte referred several postcrania

Borealopelta (meaning 'northern shield') is an extinct genus of herbivorous nodosaurid ankylosaur from the Lower Cretaceous of what is today Alberta, Canada. It contains a single species, B. markmitchelli, named in 2017 by Caleb Brown and colleagues from a well-preserved specimen known as the Suncor nodosaur. Discovered at an oil sands mine north of Fort McMurray, Alberta, the specimen is remarkable for being among the best-preserved dinosaur fossils of its size ever found. It preserved not only the armor (osteoderms) in their life positions, but also remains of their keratin sheaths, overlyin

Patagotitan is a genus of titanosaurian sauropod dinosaur from the Early Cretaceous (Albian stage) Cerro Barcino Formation in Chubut Province, Patagonia, Argentina. The genus contains a single species known from at least six young adult individuals, Patagotitan mayorum, which was first announced in 2014 and then named in 2017 by José Carballido and colleagues. Originally thought to be the largest known titanosaur and land animal overall, preliminary studies and press releases suggested that Patagotitan had an estimated length of and an estimated weight of . Later research revised the length es

Zephyrosaurus (meaning "westward wind lizard") is a genus of orodromine ornithischian dinosaur based on a partial skull and postcranial fragments discovered in the Early Cretaceous (Aptian-Albian) Cloverly Formation of Carbon County, Montana, USA. New remains are under description, and tracks from Maryland and Virginia, also in the US, have been attributed to animals similar to Zephyrosaurus.

Aepisaurus (; derived from the Greek: , '''' - 'lofty/high' and , '''' - 'lizard', i.e. "lofty lizard") was a genus of sauropod dinosaur from the Albian-age Lower Cretaceous Grès vert of Département du Vaucluse, France, around 100.5 million years ago. It is an obscure genus from an unknown family, represented by a single humerus, now partly lost. Despite its lack of popularity, or perhaps because of it, it has been misspelled several ways in the scientific literature, with multiple dates given to the year of description as well.

Abydosaurus (meaning "Abydos lizard") is a genus of brachiosaurid sauropod dinosaur known from skull and postcranial material found in upper Lower Cretaceous rocks of northeastern Utah, United States.

Microvenator (meaning "small hunter") is a genus of oviraptorosaurian theropod dinosaur from the Early Cretaceous Cloverly Formation in what is now south central Montana. The holotype fossil is an incomplete skeleton, most likely a juvenile with a length of , and consequently, the adult size remains uncertain. Microvenator is primitive and may be the "sister taxon to all other oviraptorosaurs."

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

Amazonsaurus ( , 'Amazon lizard') is a genus of diplodocoid sauropod dinosaur from the Early Cretaceous Period of what is now South America. It would have been a large-bodied quadrupedal herbivore with a long neck and whiplash tail. Although more derived diplodocoids were some of the longest animals ever to exist, Amazonsaurus was probably not more than 12 meters (40 ft) long. Gregory S. Paul estimated in 2010 its weight at 5000 kg.

Thomas Holtz estimated its length at in 2012.

Anoplosaurus (meaning "unarmored or unarmed lizard") is an extinct genus of herbivorous nodosaurid dinosaur from the Lower Cretaceous (late Albian age) Cambridge Greensand of Cambridgeshire, England. It has in the past been classified with either the armored dinosaurs or the ornithopods, but current thought has been in agreement with the "armored dinosaur" interpretation, placing it in the Ankylosauria.

Auroraceratops, meaning "dawn horned face", is a genus of bipedal basal neoceratopsian dinosaur, from the Early Cretaceous (Aptian age) of north central China. The etymology of the generic name refers to its status as an early ceratopsian and also to Dawn Dodson, wife of Peter Dodson, one of the palaeontologists who described it.

Helioceratops is a genus of herbivorous neoceratopsian dinosaur from the Middle Cretaceous of China.

Aquilops is an early herbivorous ceratopsian dinosaur dating from the Early Cretaceous of North America, approximately 109 million to 104 million years ago. The type species is A. americanus.

The genus contains two species, Z. luoyangensis, named in 2007, and Z. junchangi, named in 2025, both known from a single partial skeleton. Zhongyuansaurus is similar to Gobisaurus, prompting some researchers to regard the genera as synonymous.

Sonorasaurus is a genus of brachiosaurid sauropod dinosaur from the Early to Late Cretaceous (Albian to Cenomanian stages, around 112 to 93 million years ago). Its fossils have been found in southern Arizona, United States. Its name, which means "Sonora lizard", comes from the Sonora River that flows in the Sonoran Desert where its fossils were first found. The type species is S. thompsoni, described by Ratkevich in 1998.

Penelopognathus (meaning "wild duck jaw") is a genus of hadrosauroid dinosaur which lived in the Early Cretaceous Bayin-Gobi Formation in what is now China. The discovery of this taxon contributes to the hypothesis that hadrosauroids originated in Asia. The type species, Penelopognathus weishampeli, named after David Weishampel, was described by Godefroit, Li, and Shang in 2005, based on fragmentary jaw fossils.

Kulceratops is a genus of ceratopsian dinosaur from the Early Cretaceous. It lived in the late Albian stage. It is one of the few ceratopsians known from this period. However, the fossils from this genus have been sparse: only jaw and tooth fragments have been found so far.

The type species is L. liudianensis. Holtz estimated it at and around . Molina-Pérez and Larramendi gave a similar size of and .

genus of neoceratopsian dinosaur (fossil)

Pukyongosaurus (meaning "Pukyong lizard", after the Pukyong National University) is a genus of titanosauriform dinosaur that lived in South Korea during the Early Cretaceous Period (Aptian - Albian). It may have been closely related to Euhelopus, and is known from a series of vertebrae in the neck and back. The characteristics that were originally used to distinguish this genus have been criticized as being either widespread or too poorly preserved to evaluate, rendering the genus an indeterminate nomen dubium among titanosauriforms. A 2022 study noted that Pukyongosaurus is probably a somphos

Erectopus (meaning "upright foot") is an extinct genus of basal allosauroid theropod from the Early Cretaceous La Penthiève Beds Formation of France and also possibly the Cernavodă Formation of southern Romania. The type species is E. superbus, which was initially known as a species of Megalosaurus.
