genus of reptiles (fossil)

Adratiklit (meaning "mountain lizard") is an extinct genus of stegosaurian dinosaur that lived on the supercontinent Gondwana during the Middle Jurassic (Bathonian age). The genus contains a single species, Adratiklit boulahfa. Its remains were found in the El Mers III Formation, near Boulemane in north Morocco.

Spicomellus is an extinct genus of unusual early ankylosaurian dinosaur from the El Mers III Formation (Bathonian age) of Morocco. The genus contains a single species, Spicomellus afer, representing the oldest named definitive ankylosaur. The species was initially described in 2021 based on a single rib with fused osteoderms, rendering its life appearance and relationships uncertain. In 2025, several additional bones, including osteoderms and cranial and postcranial remains, were described, revealing that it bears a unique array of spines over the body, including extremely elongated spikes aro

Bashanosaurus (meaning "Bashan lizard") is an extinct genus of stegosaurian dinosaur from the Middle Jurassic (Bathonian age) Shaximiao Formation of Yunyang County, China. The genus contains a single species, Bashanosaurus primitivus, known from incomplete skeletons belonging to three individuals. It is one of the basalmost stegosaurs, as well as one of the oldest known stegosaurs, along with Adratiklit, Isaberrysaura, and Thyreosaurus.

Enigmacursor (meaning "puzzle runner") is an extinct genus of neornithischian dinosaur from the Late Jurassic Morrison Formation of Colorado, United States. The type species is Enigmacursor mollyborthwickae.

Baiyinosaurus (meaning "Baiyin reptile") is an extinct genus of stegosaurian dinosaurs from the Middle Jurassic Wangjiashan Formation of China. The genus contains a single species, B. baojiensis, known from a partial skeleton including cranial bones. The skeletal anatomy of Baiyinosaurus demonstrates transitional features between basal thyreophorans and stegosaurs. While many stegosaurs are known from China, Baiyinosaurus is the only one currently named from Gansu Province.

Comptonatus (meaning "the Compton thunderer") is a genus of ornithopod dinosaur from the early Cretaceous period. Its remains are known from the Wessex Formation in England. The type and only species is C. chasei.

Pendraig (meaning "chief dragon" in Middle Welsh) is a genus of coelophysoid theropod dinosaur from South Wales. It contains one species, Pendraig milnerae, named after Angela Milner. The specimen was discovered in the Pant-y-Ffynnon quarry. In life it would have measured in length.

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.

Ferenceratops is an extinct genus of ceratopsian dinosaurs known from the Late Cretaceous (Maastrichtian) Sânpetru and Densuș-Ciula formations of Romania. The genus contains a single species, Ferenceratops shqiperorum, known from a partial skeleton and pelvis. These fossils, in addition to many other isolated or associated remains, were originally referred to the ornithopod Zalmoxes. Phylogenetic analyses based on new remains of Ajkaceratops suggest Ferenceratops was a close relative of this genus, as part of a distinct lineage of previously unrecognized European ceratopsians.

Brighstoneus (after Brighstone, a village on the Isle of Wight) is a genus of hadrosauriform dinosaur from the Early Cretaceous Wessex Formation of the Isle of Wight, England. The genus contains a single species, Brighstoneus simmondsi, known from a partial skeleton.
