Algoasaurus is a genus of sauropod dinosaur from the Berriasian-early Valanginian-age Early Cretaceous Upper Kirkwood Formation of Cape Province, South Africa, specifically near a town called Despatch. Only one species, A. bauri, is known.
Alocodon is a genus of ornithischian dinosaur known from multiple teeth from the Middle or Late Jurassic Cabaços Formation of Portugal, and also the Forest Marble and Chipping Norton Formations of England. A single species is known, A. kuehnei.
"Coelosaurus" antiquus is a dubious species of theropod dinosaurs. It was named by Joseph Leidy in 1865 for two tibiae found in the Navesink Formation of New Jersey.
Dryptosauroides is the name given to a dubious genus of dinosaur from the Late Cretaceous. It was a large theropod, possibly belonging to the Abelisauroidea. It has been estimated as 10 meters long and 1.5 tonnes in weight.
The Candeleros Formation is a geologic formation that crops out in the Río Negro, Neuquén, and Mendoza provinces of northern Patagonia, Argentina. It is the oldest formation in the Neuquén Group and belongs to the Rio Limay Subgroup. Formerly that subgroup was treated as a formation, and the Candeleros Formation was known as the Candeleros Member.
The Los Colorados Formation is a sedimentary rock formation of the Ischigualasto-Villa Unión Basin, found in the provinces of San Juan and La Rioja in Argentina. The formation dates back to the Norian age of the Late Triassic.
La Rioja is an autonomous community and province in Spain, in the north of the Iberian Peninsula. Its capital is Logroño. Other cities and towns in the province include Calahorra, Arnedo, Alfaro, Haro, Santo Domingo de la Calzada, and Nájera. It has an estimated population of 315,675 inhabitants, making it the least populated autonomous community of Spain.
The Urbión Group is a geological group in Castile and León and La Rioja, Spain whose strata date back to the Early Cretaceous (late Hauterivian to late Barremian. The formations of the group comprise a sequence of brown limestones in a matrix of black silt, sandstones, claystones and conglomerates deposited under terrestrial conditions, in alluvial fan and fluvial environments.
The Camarillas Formation is a geological formation in the Teruel Province of Aragón, Spain whose strata date back to the Early Cretaceous. The sandstones, mudstones and conglomerates of the formation, that due to syn-sedimentary faulting varies greatly in thickness from 300 to 800 metres, were deposited in fluvial, deltaic and lacustrine environments.
The Enciso Group is a geological formation in La Rioja, Spain whose strata date back to the Early Cretaceous.
The Hornitos Formation is a Campanian geologic formation of the Algarrobal Basin in the Atacama Region of northern Chile. The formation comprises limestones, sandstones, conglomerates, marls and tuff. Dinosaur remains are among the fossils that have been recovered from the formation, including the sauropod Arackar licanantay.
The Villar del Arzobispo Formation is a Late Jurassic to possibly Early Cretaceous geologic formation in eastern Spain. It is equivalent in age to the Lourinhã Formation of Portugal. It was originally thought to date from the Late Tithonian-Middle Berriasian, but more recent work suggests a Kimmeridigan-Late Tithonian, possibly dating to the Early Berriasian in some areas. The Villar del Arzobispo Formation's age in the area of Riodeva in Spain has been dated based on stratigraphic correlations as middle-upper Tithonian, approximately 145-141 million years old. In the area of Galve, the formation potentially dates into the earliest Cretaceous.
The Higueruelas (Spanish) or Higuerueles Formation (Catalan) is a Tithonian geologic formation in the Teruel and Valencia provinces of Spain. Fossil sauropod tracks have been reported from the formation.
Parabrontopodus is an ichnogenus of dinosaur footprint, that was initially described by Lockley et al. in 1994, and was assigned to Sauropoda by Lockley in 2002 and in 2004 by Niedzwiedzki and Pienkowski. Various species through their footprints that are characterized by the association of two impressions left by hand and foot. The acquisition of a specific family is complex, but now in most cases, they have been considered diplodocoids and similar animals. The reason is that their traces left are large, but in proportion to the size, from animals, seem very light because the depth of imprint is low.
Abelichnus is an extinct ichnogenus of dinosaur footprint from the Candeleros Formation and the Rio Limay Formation. The type ichnospecies, Abelichnus astigerrae, was first discovered in Argentina in 1987 and was recorded as the biggest known dinosaur footprint ever discovered. Abelichnus probably grew to a size of 12.5-13 meters long.
Gideonmantellia is an extinct genus of basal ornithopod dinosaur known from the Early Cretaceous Camarillas Formation of Galve, Province of Teruel, Spain. It contains a single species, Gideonmantellia amosanjuanae.
The Piedrahita de Muñó Formation is an Early Cretaceous geologic formation of the Cameros Basin in northern Spain. Fossil theropod tracks have been reported from the formation. Also fossils of Lepidotes sp., Polacanthus sp. and Testudines indet. were found in the formation.
Guegoolithus is an oogenus of fossil egg from the early Cretaceous of Spain. It is classified in the oofamily Spheroolithidae, and was probably laid by an ornithopod dinosaur.
Baryonychinae is an extinct clade or subfamily of spinosaurids from the Early Cretaceous (Valanginian-Albian) of Britain, Portugal, and Niger. The clade was named by Charig & Milner in 1986 and defined by Sereno et al. in 1998 and Holtz et al. in 2004 as all taxa more closely related to Baryonyx walkeri than to Spinosaurus aegyptiacus.
Bonaparteichnium is a dinosaur ichnogenus known from the Candeleros Formation of Neuquén Province, Argentina. It was named by Jorge O. Calvo in a 1991 paper, alongside the other ornithopod ichnogenera Sousaichnium and Limayichnus. The name of the genus honours Argentinian palaeontology José Bonaparte for his contributions to palaeontology in Argentina. The taxon was named for a 60cm footprint of a bipedal ornithopod; the heel of the track is 28cm long, making it 45% of the track. This length, above that expect for an ornithopod foot, along with the width and robustness of the heel, was the distinguishing trait cited in naming the specimen as a new ichnospecies, and is the basis of the species name tali, referring to word "talon" which means heel. In a 1999 paper Calvo would revise his opinion and consider his three ichnogenera to be synonyms. He noted the extreme similarity of the front half of the foot between Bonaparteichnium and Limayichnus, and that the length and size of a heel in a track is dependent on the method of walking; a bipedal animal walking abnormally low to the ground would produce a track such as that used to name Bonaparteichnium even in lack of a large heel as a genuine anatomical feature. He referred to B. tali as a nomen vanum. In a literature review of hadrosaur ichnotaxa, Ignacio Díaz-Martínez and colleagues considered it a nomen dubium as opposed to referring the specimen to Limayichnus, as they also considered that taxon dubious. They noted that Bonaparteichnium can also be considered a taphotaxon, a term proposed by Spencer G. Lucas to refer to invalid taxa who were thought distinct due to taphonomic distortions.
