Taxa named by Kenneth Carpenter

Gojirasaurus is a genus of coelophysoid theropod dinosaur named after the giant monster movie character Godzilla. It lived in the Late Triassic Period, containing a single known species, Gojirasaurus quayi.

Hesperosaurus (from Ancient Greek ἕσπερος (hésperos), meaning "western", and σαῦρος (saûros), meaning "lizard") is a herbivorous stegosaurian dinosaur from the Kimmeridgian age of the Jurassic period, approximately 156 million years ago.

Cedarosaurus (meaning "Cedar lizard" - named after the Cedar Mountain Formation, in which it was discovered) is a genus of nasal-crested macronarian sauropod dinosaur from the Early Cretaceous Period (Valanginian). The fossils were discovered in 1996 in eastern Utah within the rocks of the Yellow Cat Member of the Cedar Mountain Formation. It was officially named and described by Tidwell, Carpenter and Brooks in 1999. It shows similarities to the brachiosaurid Eucamerotus from the Wessex Formation of southern England, as well as to Brachiosaurus from the Morrison Formation.

Animantarx ( ; meaning 'living citadel') is a genus of nodosaurid ankylosaurian dinosaur from the Early and Late Cretaceous of western North America. Like other nodosaurs, it would have been a slow-moving quadrupedal herbivore covered in heavy armor scutes, but without a tail club. The skull measures approximately 25 cm (10 inches) in length, suggesting the animal as a whole was no more than 3 meters (10 feet) long.

The key rebbachisaurid features are the spinopostzygapophyseal laminae that extends dorsomedially from the postzygapophyses to join and form the postspinal lamina, and the pneumatic neural spine and arch. Other rebbachisaurid features include the rather simple ("attenuated") structure of the neural spine and the respective inclinations of the centrodiapophyseal lamina and the postzygodiapophyseal l

Gargoyleosaurus (meaning "gargoyle lizard") is one of the earliest ankylosaurs known from reasonably complete fossil remains. The holotype was discovered in 1995 at the Bone Cabin Quarry West locality, in Albany County, Wyoming in exposures of the Upper Jurassic (Kimmeridgian to Tithonian stages) Morrison Formation.

Tanycolagreus is a genus of coelurosaurian theropod dinosaur from the Late Jurassic (Kimmeridgian to Tithonian) of the U.S. states of Wyoming, Utah, and Colorado.

Mymoorapelta (Meaning "Shield from the Mygatt-Moore Quarry" after a combination of the names of the discoverers of the Mygatt-Moore Quarry that fossils were originally collected from, and the Greek word πέλτα, meaning "shield") is a nodosaurid ankylosaur from the Late Jurassic (Kimmeridgian-Tithonian, around 155 to 150 million years ago) Morrison Formation (Brushy Basin Member) of western Colorado and central Utah, USA. The animal is known from a single species, Mymoorapelta maysi, and few specimens are known. The most complete specimen is the holotype individual from the Mygatt-Moore Quarry,

Niobrarasaurus (meaning "Niobrara lizard") is an extinct genus of nodosaurid ankylosaurian dinosaur which lived during the Late Cretaceous, around 87 to 82 million years ago. Its fossils were found in the Smoky Hill Chalk Member of the Niobrara Formation, in western Kansas, which would have been near the middle of the Western Interior Seaway during the Late Cretaceous. It was probably closely related to Nodosaurus.

thumb|Holotype skull of Libonectes morgani Libonectes is an extinct genus of sauropterygian reptile belonging to the plesiosaur order. It is known from specimens found in the Britton Formation of Texas (USA) and the Akrabou Formation of Morocco, which have been dated to the lower Turonian stage of the late Cretaceous period.

Cedarpelta is an extinct genus of basal ankylosaurid dinosaur from Utah that lived during the Late Cretaceous period (Cenomanian to lower Turonian stage, 98.2 to 93 Ma) in what is now the Mussentuchit Member of the Cedar Mountain Formation. The type and only species, Cedarpelta bilbeyhallorum, is known from multiple specimens including partial skulls and postcranial material. It was named in 2001 by Kenneth Carpenter, James Kirkland, Don Burge, and John Bird. Cedarpelta has an estimated length of 7 metres (23 feet) and weight of 5 tonnes (11,023 lbs). The skull of Cedarpelta lacks extensi

Harpactognathus (meaning "seizing/grasping jaw") is a genus of pterosaur, a group of extinct flying reptiles, that lived during the Kimmeridgian stage of the Late Jurassic period in what is now Wyoming, United States. Harpactognathus is confidently known from a single, incomplete rostrum (front of the skull) found in 1996 at the Bone Cabin Quarry, though an incomplete mandible (lower jaw bone) and humerus (upper arm bone) from the quarry have tentatively been referred to the genus. The rostrum was described by paleontologist Kenneth Carpenter and colleagues in 2003, who named the type and only

Alcovasaurus is an extinct genus of herbivorous stegosaurian dinosaurs that lived in the Late Jurassic. It was found in the Morrison Formation of Wyoming, United States. The genus contains a single species, Alcovasaurus longispinus, originally assigned to the genus Stegosaurus. It is likely a member of the Dacentrurinae, and has been referred to the genus Miragaia by some authors.

Plesiopleurodon (/ˌpliːsiəˈplʊərədɒn/; , meaning "near to", pleuro, meaning "side", and don, meaning "tooth") is an extinct genus of Mesozoic marine reptiles, belonging to the Sauropterygia, known from the Late Cretaceous of North America. It was named by Kenneth Carpenter based on a complete skull with a mandible, cervical vertebra, and a coracoid. In naming the specimen, Carpenter noted "Of all known pliosauroids, Plesiopleurodon wellesi most closely resembles Liopleurodon ferox from the Oxfordian of Europe, hence the generic reference." It was initially described as a pliosauroid due to it

Pectinodon is a genus of troodontid theropod dinosaurs from the end of the Maastrichtian age of the Late Cretaceous period (66 mya). It currently contains a single valid species, Pectinodon bakkeri (sometimes classified as Troodon bakkeri), known only from teeth.

Cedrorestes is a genus of iguanodontian dinosaur from the Early Cretaceous of Utah. It is based on an incomplete skeleton which was found in the Valanginian-age Yellow Cat Member of the Cedar Mountain Formation.

Theiophytalia is a genus of herbivorous iguanodontian dinosaur from the lower Cretaceous period (Aptian-Albian stage, about 112 million years ago) of Colorado, USA. It contains a single species, T. kerri.

Venenosaurus ( ) is a genus of sauropod dinosaur that lived in what is now Utah during the Early Cretaceous. Its type and only species is Venenosaurus dicrocei. Fossils of Venenosaurus were first discovered in 1998, by Denver Museum of Natural History volunteer Anthony DiCroce, and described as a new genus and species in 2001 by Virginia Tidwell and colleagues, who named the species for DiCroce. Venenosaurus was a relatively small sauropod, and was similar to Cedarosaurus, another sauropod from the Early Cretaceous of Utah.

Uteodon (meaning "Ute tooth") is a genus of herbivorous iguanodontian dinosaur. It is a basal iguanodontian which lived during the late Jurassic period (Tithonian age) in what is now Uintah County, Utah. It is known from the middle of the Brushy Basin Member, Morrison Formation. The genus was named by Andrew T. McDonald in 2011 and the type species is U. aphanoecetes. ==History== The holotype specimen, CM 11337 (a virtually complete skeleton minus the skull and tail), was assigned to Camptosaurus medius (Marsh, 1894) by Charles W. Gilmore in 1925. When C. medius was synonymised with Camptosaur

Planicoxa is a genus of advanced iguanodontian dinosaur from the Early Cretaceous of North America. It is known from the partial skeletons of several individual specimens. Its fossils were discovered in Utah, United States.

Peloroplites (meaning "monstrous heavy one") is a monospecific genus of nodosaurid dinosaur from Utah that lived during the Late Cretaceous (Cenomanian to lower Turonian stage, 98.2 to 93 Ma) in what is now the Mussentuchit Member of the Cedar Mountain Formation. The type and only species, Peloroplites cedrimontanus, is known from a partial skull and postcranial skeleton. It was named in 2008 by Kenneth Carpenter and colleagues. Peloroplites was 6 metres (20 feet) long and weighed 2 tonnes (4,410 lbs), making it one of the largest known nodosaurids, and came from a time when ankylosaurids and

Callawayasaurus is a genus of plesiosaur from the family Elasmosauridae. When the holotype was first described by Samuel Paul Welles in 1962, it was described as Alzadasaurus colombiensis before being moved into its current genus by Kenneth Carpenter in 1999.
