Fukuiraptor was a medium-sized megaraptoran theropod dinosaur of the Early Cretaceous epoch that lived in what is now Japan. Fukuiraptor is known from the Kitadani Formation and possibly also the Sebayashi Formation.
Fukuisaurus is a genus of herbivorous ornithopod dinosaur that lived during the Early Cretaceous in what is now Japan. The type species is F. tetoriensis, which was named and described in 2003.
Pukyongosaurus is a genus of titanosauriform dinosaur that lived in South Korea during the Early Cretaceous Period. 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. The 2022 study noted that Pukyongosaurus is probably a somphospondylan.
Dongyangosaurus is a genus of titanosaurian sauropod dinosaur from the Late Cretaceous. The only species is Dongyangosaurus sinensis, from which only a single fragmentary skeleton is known, coming from the Zhejiang province of eastern China. It was described and named by Lü Junchang and colleagues. Like other sauropods, Dongyangosaurus would have been a large quadrupedal herbivore.
The Fukui Prefectural Dinosaur Museum, located in Katsuyama, Fukui, Japan, is one of the leading dinosaur museums in Asia that is renowned for its exhibits of fossil specimens of dinosaurs and paleontological research. It is sited in the Nagaoyama Park near the Kitadani Dinosaur Quarry that the Lower Cretaceous Kitadani Formation of the Tetori Group is cropped out and a large number of dinosaur remains including Fukuiraptor kitadaniensis and Fukuisaurus tetoriensis are found and excavated.
The Kitadani Formation is a unit of Lower Cretaceous sedimentary rock which crops out near the city of Katsuyama in Fukui Prefecture, Japan, and it is the primary source of Cretaceous-aged non-marine vertebrate fossils in Japan. Dinosaur remains are among the fossils that have been recovered from the formation, but it also preserves a diverse assemblage of plants, invertebrates, and other vertebrates. Most, if not all, of the fossil specimens collected from the Kitadani Formation are reposited at the Fukui Prefectural Dinosaur Museum.
Albalophosaurus is a genus of marginocephalian ornithischian dinosaur that lived in Japan during the Early Cretaceous. The type species is Albalophosaurus yamaguchiorum.
The Amagodani Formation is an Early Cretaceous geologic formation in Japan. An indeterminate iguanodontian tooth has been recovered from the formation. as well as indeterminate pterosaur remains. Dinosaur footprints are also known from the formation.
The Kuwajima Formation is an Early Cretaceous geologic formation in Japan. Its precise age is uncertain due to a lack of identifying fossils, and it was previously considered likely Valanginian to Hauterivian in age. However, it is now considered to probably be Barremian in age. Dinosaurs and other vertebrates has been recovered from the Kaseki-kabe "Fossil-bluff" locality in the uppermost part of the formation.
Tambatitanis is an extinct genus of titanosauriform, possibly a titanosaurian, sauropod dinosaur from the Early Cretaceous aged Ohyamashimo Formation of the Sasayama Group. It is known from a single species, Tambatitanis amicitiae, known from a partial skeleton.
Koshisaurus is a monospecific genus of basal hadrosauroid from the Kitadani Formation in Japan. The discovery of the genus suggests that hadrosauroids had higher diversity along the eastern margin of Asia in the Early Cretaceous. "Koshi" means an old Japanese regional name including Fukui prefecture where fossils of the genus were discovered.
Sirindhorna is a genus of hadrosauroid ornithopod dinosaur from Early Cretaceous deposits of northeastern Thailand.
Fukuivenator is an extinct genus of maniraptoran theropod dinosaur from the Early Cretaceous of Japan.
Nipponoolithus is an oogenus of fossil egg native to Japan. It is one of the smallest known dinosaur eggs, and was probably laid by some kind of non-avian maniraptor.
Plagioolithus is an oogenus of fossil egg. It is from the Early Cretaceous of Japan. It was probably laid by a bird, making it the oldest known fossil bird egg.
Sibirotitan is a genus of somphospondyl sauropod from the Ilek Formation of Russia. The type and only species is S. astrosacralis.
Symmetrolestes is an extinct genus of small spalacotheriid mammal from the Early Cretaceous period of Japan. The genus contains one species known as S. parvus, the type fossil is from fluvial deposits located in the Dinosaur Quarry in the Kitadani Formation, near the city of Katsuyama which lies alongside valley of the Sugiyamagawa River. It was described by Tsubamoto and Rougier in 2004. The holotype is kept at the National Science Museum, Tokyo, Japan.
Fukuipteryx is an extinct genus of basal avialan dinosaurs found in Early Cretaceous deposits from Japan's Kitadani Formation. It contains one species, Fukuipteryx prima.
Tyrannomimus is an extinct genus of ornithomimosaurian theropod dinosaurs from the Kitadani Formation of Japan. The type species is Tyrannomimus fukuiensis.
Tedorosaurus is a genus of extinct lizard-like reptile known from Callovian section of the Fukui Prefecture, Japan. This genus is represented by single species Tedorosaurus asuwaeneis. It is the first Mesozoic terrestrial reptile fossil from Japan.
