Trimucrodon is a genus of ornithischian dinosaur from the Late Jurassic Lourinhã Formation of Portugal. The type, and currently only, species is T. cuneatus.
Neuquensaurus is a genus of saltasaurid sauropod dinosaur that lived in the Late Cretaceous, about 80 million years ago in Argentina in South America. Its fossils were recovered from outcrops of the Anacleto Formation around Cinco Saltos, near the Neuquén river from which its name is derived.
Pular is a massive stratovolcano located in the Antofagasta Region of northern Chile, about 15 km west of the border with Argentina, which in this area is a straight line between the summits of Socompa volcano and Cerro del Rincón. Pular, along with Cerro Pajonales, forms a high volcanic ridge, which runs in a generally north-east to south-west direction for 12 km (7 mi). Southward, following the same direction as the ridge, lies Socompa volcano. The ridge's crest forms a drainage divide between Salar de Atacama basin and Salar de Pular basin. This latter is a bowl-shaped basin enclosed on the east by Aracar volcano.
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 Arén Formation or Arén Sandstone is a geological formation in the Tremp-Graus Basin around Arén, Catalonia, Spain whose strata date back to the Late Cretaceous. Dinosaur remains are among the fossils that have been recovered from the formation. The formation dates to the Campanian to Maastrichtian and underlies the Tremp Group.
The Viñita Formation is a geological formation in Coquimbo, Chile, whose strata date back to the Late Cretaceous. Dinosaur remains are among the fossils that have been recovered from the formation.
The Los Blanquitos Formation is a geological formation in Salta Province, Argentina whose strata date back to the Campanian age of the Late Cretaceous Period. Dinosaur remains are among the fossils that have been recovered from the formation. The formation consists of friable, micaceous, grayish-red sandstones with quartz pebbles containing small carbonate veins. In the base of this layer the remains of a titanosaurid dinosaur were discovered. Above the layer with bones appears a lens of thick, greenish-gray, calcareous, very hard sandstone with pebbles and gravel. The bones were covered by a "halo" of the same rock but of greenish or grayish color, especially visible because the normal sediment is red. The bed thickness is 1.5 metres (4.9 ft).
The Guichón Formation is a Late Cretaceous geologic formation of the Paysandú Group in Uruguay. Dinosaur remains are among the fossils that have been recovered from the formation.
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 Puerto Yeruá Formation is a Late Cretaceous geologic formation in the Paraná Basin, pertaining to Entre Ríos Province, Argentina. Dinosaur remains are among the fossils that have been recovered from the formation, as well as egg fragments and fossilized wood.
The Tereñes Formation or Tereñes Marl is a Late Jurassic (Kimmeridgian) geologic formation in Asturias, Spain. The grey marls of the formation were deposited in a lagoonal environment at a muddy coast along a temporary inland sea. The lower section of the formation comprises silty and chalky sandstones with desiccation cracks and ripple marks, then becomes a bituminous, prominently ostracod-bearing, pelecypod shell chalk, lime chalk marl and marl. Fossil tracks have been reported from the formation.
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.
The Vilquechico Formation is a Late Campanian to Late Maastrichtian geologic formation in southern Peru. Fossil ornithopod tracks have been reported from the formation. The formation overlies the Ayabacas Formation and is overlain by the Auzangate Formation.
Atacamatitan is a genus of titanosaurian sauropod dinosaurs from the Late Cretaceous Tolar Formation of Chile.
Jorquera is a caldera in Chile, 70 kilometres (43 mi) southeast of Copiapo.
Estratos de Pupunahue is the name given to the sedimentary strata of Oligocene-Miocene age that crop out in Pupunahue and Mulpún near Valdivia, Chile. Outside this locality Estratos de Pupunahue extends below the surface over a larger area. The thickness of the strata varies from a few meters to 530 meters. The strata were initially described by Henning Illies. The strata are made up of conglomerate, sandstone and mudstone. The clast of the conglomerates are made up of metamorphic rock and the disposition of the conglomerates varies from clast-supported to matrix-supported. The sandstone and mudstone contain layers of lignite coal that exceed 30 cm in thickness.
Caldera Basin is a sedimentary basin located in the coast of northern Chile west of Copiapó. The basin has a fill of marine sediments of Late Cenozoic age. With a north-south extension of 43 kilometres (27 mi) and an east-west width of 20 kilometres (12 mi) the basin occupies an area between the coast and the Chilean Coast Range and between the port of Caldera and the mouth of Copiapó River. The sedimentary fill rests on metamorphic rocks of Paleozoic age and on plutonic rocks of Mesozoic age.
Mininco Formation is a geological formation composed of sediments that deposited during the Pliocene in central Chile. Near Angol the formation reaches thicknesses of up to 300 m. The upper strata of the formation contain tuff layers and coal beds that are rich in leaf fossils. Other fossils that have been found in the formation include fresh-water diatoms and bivalves.
Caleta Chonos Formation is a geological formation of Oligocene age located around Chacao Channel in southern Chile. The formation overlies Bahía Mansa Metamorphic Complex and is overlain by the Ancud Volcanic Complex. It crops out in northwestern Chiloé Island in the isthmus of Lacuy Peninsula.
The Pajarito Mountains are a small mountain range in the Atacama Desert of Chile on the west coast of South America. Together with Paico Peak they divide the Algarrobal Basin into two hydrological units.
