Dinosaur genera

Halticosaurus (pron.:"HAL-tick-oh-SORE-us") is a dubious genus of theropod dinosaur from the late Triassic period (middle Norian stage, around 215.6–208 million years ago). It is known from a single fragmentary fossil specimen of the species H. longotarsus, found in the Middle Stubensandstein formation of what is present-day Germany The only known specimen was poorly preserved and may have been put together from bones of unrelated animals. Further research would be required to determine which of the bones belonged together, and what kind of theropod Halticosaurus was. However, most of the

Changchunsaurus (meaning "Changchun lizard") is an extinct genus of small herbivorous neornithischian dinosaur from Early or Late Cretaceous deposits of Gongzhuling, Jilin, China. It is the first named dinosaur genus from that region.

Baotianmansaurus is an extinct genus of somphospondylian sauropod. Its fossils were discovered in the Late Cretaceous Gaogou Formation of Henan Province, China. The type and only species is B. henanensis — named after the province in which it was found. ==Discovery and naming== The fossils of Baotianmansaurus were discovered at a locality called Neixiang, near Nanyang City in the Henan Province of China. This locality is part of the Baotianman National Nature Reserve corresponds to the rocks of the Gaogou Formation. Dinosaur body fossils in this formation are rare, but a wide variety of egg fo

It has never been formally given a species name, but is often seen as N. praecursor, which actually comes from a different animal. Often in the past, it had been assigned to the wastebasket taxon Pelorosaurus, but restudy has suggested that it could be related to Turiasaurus, a roughly contemporaneous giant Spanish sauropod. It is only known from six teeth.

While no skull was recovered, the specimen (BVP-112) is known from a fair amount of post-cranial material that shows it was a fairly derived oviraptorosaur (slightly more advanced than Nomingia), of superfamily Caenagnathoidea. Lü et al. (2003, 2005) describe it as an oviraptorid, but it could be a caenagnathid .

It is known from the Bayanshiree Formation of Mongolia, and its fossils were found between 2002 and 2003 during field expeditions. Erketu was first described in 2006 and later on in 2010 due to some cervicals that were left behind in the expedition. This genus represents the first sauropod described from the Bayanshiree Formation. The elongated cervical vertebrae indicate that it probably had the longest neck relative to its

It was a member of Abelisauridae, closely related to genera such as Carnotaurus. The only known remains of this genus are leg bones which share certain similarities to a variety of abelisaurids. However, these bones lack unique features, which may render Quilmesaurus a nomen vanum (more commonly known as a nomen dubium, or "dubious name").

Pamparaptor (, meaning "thief of the Pampas") is an extinct genus of paravian theropod dinosaur from the Late Cretaceous Portezuelo Formation of the Neuquén province in Argentine Patagonia. Its precise classification is uncertain, but the authors who described this taxon have argued that it is a dromaeosaurid. The genus contains a single species, P. micros (from the Greek word for "small"), which is known from a single specimen consisting of a mostly complete and fully-articulated left foot, which preserves the iconic dromaeosaur-like "killing claw". ==Discovery== The type and only specimen of

Ziapelta is an extinct genus of ankylosaurid. Its fossils have been found in the Hunter Wash and De-na-zin members of the Kirtland Formation of Upper Cretaceous (Campanian) New Mexico. It was named in 2014, in a research paper led by ankylosaur researcher Victoria Arbour. There is a single species in the genus, Ziapelta sanjuanensis. The genus is named after the Zia sun symbol, a stylized sun with four groups of rays, having religious significance to the Zia people of New Mexico, and the iconic symbol on the state flag of New Mexico, and pelta (Latin), a small shield, in reference to the osteo

The type and only known species is A. hutchisoni; the type specimen consists only of a broken . It constitutes the oldest known lambeosaur remains from North America, as well as the only known lambeosaur species from the Wahweap Formation, of which it pertains to the Upper Member. Among its relatives, it seems to be particularly similar to Parasaurolophus, rather than animals like Lambeosaurus; phylogenetic analysis confirms this, finding it

Tazoudasaurus is a genus of gravisaurian (probably vulcanodontid) sauropod dinosaurs from the late Early Jurassic (Toarcian). It was recovered in the "Toundoute Continental Series" (Azilal Formation), located in the High Atlas Mountains of Morocco in North Africa.
