Hauterivian dinosaurs

Wuerhosaurus is an extinct genus of stegosaurine stegosaur dinosaurs from the Early Cretaceous of China. The genus contains two species, Wuerhosaurus homheni, the type species named in 1973, and Wuerhosaurus ordosensis, named in 1993. It is one of the youngest (most recent) known stegosaurs in the fossil record, alongside Mongolostegus and Yanbeilong.

Albalophosaurus (meaning 'white crest lizard') is a genus of marginocephalian ornithischian dinosaur that lived in Japan during the Early Cretaceous. The type species is Albalophosaurus yamaguchiorum.

Phuwiangosaurus (meaning "Phu Wiang lizard") is a genus of titanosauriform dinosaur from the Early Cretaceous (Valanginian-Hauterivian) Sao Khua Formation of Thailand. The type species, P. sirindhornae, was described by Martin, Buffetaut, and Suteethorn in a 1993 press release and was formally named in 1994. The species was named to honor Princess Maha Chakri Sirindhorn of Thailand, who was interested in the geology and palaeontology of Thailand, while the genus was named after the Phu Wiang area, where the fossil was discovered. The precise affinities of Phuwiangosaurus among titanosauriform

Volgatitan (meaning "Volga giant") is a genus of titanosaurian sauropod dinosaur from the Early Cretaceous of the Ulyanovsk Oblast, Russia. The type and only species is Volgatitan simbirskiensis, known from seven from a single individual. It is the oldest known titanosaur from the northern hemisphere, and is considered important for being related to the Lognkosauria, a group known only from South America later in the Late Cretaceous. It was first described in November 2018 by Russian palaeontologists Alexander Averianov and Vladimir Efimov. It is estimated to have weighed about .

Vectipelta (meaning "Isle of Wight shield") is an extinct genus of ankylosaurian dinosaur recovered from the Early Cretaceous Wessex Formation of England. The genus contains a single species, V. barretti, known from a partial skeleton including several osteoderms. It was historically known as the "Spearpoint ankylosaur" prior to its description.

Xunmenglong (from ) is a genus of compsognathid theropod dinosaur from the Huajiying Formation of Hebei Province, China. The type and only species is Xunmenglong yinliangis. The holotype material consists of a pelvis, tail base and hindlimbs that had previously been part of a chimera containing three different animals. The animal is described as being the smallest known member of Compsognathidae, being about the size of the sub-adult Scipionyx holotype specimen, or approximately in length.

Thecospondylus (THEEK-o-SPON-di-lus, "sheath vertebra") is a dubious genus of dinosaur from the Early Cretaceous of England. Scientists are unsure as to whether Thecospondylus was a saurischian or an ornithischian.

Tietasaura (meaning "Tieta lizard") is an extinct genus of elasmarian ornithopod dinosaur from the Early Cretaceous Marfim Formation of Brazil. The genus contains a single species, T. derbyiana, known from a single incomplete femur. Tietasaura is notable for being the first ornithischian dinosaur ever named from Brazil.
