Theropoda
Theropoda (; ), whose members are known as theropods, is a dinosaur clade that is characterized by hollow bones and three toes and claws on each limb. Theropods are generally classed as a group of saurischian dinosaurs. They were ancestrally carnivorous, although a number of theropod groups evolved to become herbivores and omnivores. Theropods first appeared during the Carnian age of the late Triassic Period (geology), period 231.4 million years ago (Year#SI prefix multipliers, Ma) and included all the large terrestrial carnivores from the Early Jurassic until at least the close of the Cretaceous, about 66 Ma. In the Jurassic, birds evolved from small specialized coelurosaurian theropods, and are today represented by about 10,500 living species. Biology Diet and teeth Theropods exhibit a wide range of diets, from insectivores to herbivores and carnivores. Strict carnivory has always been considered the ancestral diet for theropods as a group, and a wider variety of di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Castellar Formation
The El Castellar Formation is a geological formation in La Rioja and Teruel, Spain whose strata date back to the possibly the Valanginian to the Barremian stages of the Early Cretaceous. Dinosaur remains are among the fossils that have been recovered from the formation.Weishampel, David B; et al. (2004). "Dinosaur distribution (Early Cretaceous, Europe)."

Cadomin Formation
The Cadomin Formation is a stratigraphic unit of Early Cretaceous (Barremian to Aptian) age in the western part of the Western Canada Sedimentary Basin. It is extends from southeastern British Columbia through western Alberta to northeastern British Columbia, and it contains significant reservoirs of natural gas in some areas. It was named after the mining town of Cadomin, which is an acronym of "Canadian Dominion Mining". Stratigraphy The Cadomin Formation is of Early Cretaceous (Barremian to Aptian) age. It is the basal unit of the Bullhead Group in northeastern British Columbia and of the Blairmore Group in Alberta. The formation is a distinctive marker horizon, and it was sometimes called the "coal conglomerate" because it was useful as a reference point for locating the coal seams of the underlying Mist Mountain Formation and the overlying Gething Formation.McLean, J.R. 1977.

Broome Sandstone
The Broome Sandstone, formerly known as the Broome Beds, is an Early Cretaceous geologic formation found in Western Australia, and formerly considered part of Dampier Group. Fossil sauropod tracks, belonging to an unknown ichnotaxon, and stegosaur tracks belonging to the ichnogenus and species '' Garbina roeorum'' have been reported from the formation.Weishampel, ''et al''.

Botucatu Formation
The Botucatu Formation is an Aptian geologic formation of the Paraná and Pelotas Basins in southern Brazil and northern Uruguay. The formation is composed of quartzitic sandstones, deposited in an eolian environment.Petrolli & Pimentel, 2014, p.1 Fossil theropod tracks have been reported from the formation.Weishampel, et al. (2004). "Dinosaur distribution." Pp. 517-607. Description The sandstone is fine-textured and well sorted, containing no pebbles; its colour is occasionally white, yellowish, and reddish, but more commonly it is pinkish. Nearly always it is silicified and therefore compact and hard. The formation was deposited in an arid desert environment, characterized by sabkhas and wadis.Leonardi, 1994, p.50 Fossil content Among the following fossils were reported from the Botucatu Formation: [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boonton Formation
The Boonton Formation is a mapped bedrock unit in New Jersey, formerly divided between the Boonton and Whitehall beds of the defunct Brunswick Formation. It is named for the town of Boonton, New Jersey, which is near where its type section was described by paleontologist Paul E. Olsen. Description The Boonton Formation is composed of reddish-brown to reddish-purple fine grained sandstone, as well as red, gray, purple, and black siltstone and mudstone. Siltstone and mudstone layers can be calcareous and feature dolomitic concretions. A well known fossil fish bed is known to exist in a carbonate rich siltstone near the top of the formation. Additionally, cross-bedded conglomerate layers interfinger with beds of the formation, usually bearing clasts of gneiss and granite.

Triassic
The Triassic ( ) is a geologic period and system which spans 50.6 million years from the end of the Permian Period 251.902 million years ago ( Mya), to the beginning of the Jurassic Period 201.36 Mya. The Triassic is the first and shortest period of the Mesozoic Era. Both the start and end of the period are marked by major extinction events. The Triassic Period is subdivided into three epochs: Early Triassic, Middle Triassic and Late Triassic. The Triassic began in the wake of the Permian–Triassic extinction event, which left the Earth's biosphere impoverished; it was well into the middle of the Triassic before life recovered its former diversity. Three categories of organisms can be distinguished in the Triassic record: survivors from the extinction event, new groups that flourished briefly, and other new groups that went on to dominate the Mesozoic Era. Reptiles, especially archosaurs, were the chief terrestrial vertebrates during this time. A specialized subgroup of archo ...

Coelophysoid
Coelophysoidea were common dinosaurs of the Late Triassic and Early Jurassic periods. They were widespread geographically, probably living on all continents. Coelophysoids were all slender, carnivorous forms with a superficial similarity to the coelurosaurs, with which they were formerly classified, and some species had delicate cranial crests. Sizes range from about 1 to 6 m in length. It is unknown what kind of external covering coelophysoids had, and various artists have portrayed them as either scaly or feathered. Some species may have lived in packs, as inferred from sites where numerous individuals have been found together. Examples of coelophysoids include ''Coelophysis'', ''Procompsognathus'' and '' Liliensternus''. Most dinosaurs formerly referred to as being in the dubious taxon "Podokesauridae" are now classified as coelophysoids. Classification Despite their very early occurrence in the fossil record, coelophysoids have a number of derived features that separate th ...

Bohdašín Formation
The Bohdašín Formation (Czech: ''Bohdašínské souvrství'') is a geologic unit of Late Triassic age (about 210 Ma), located in the Czech Republic. A small tridactyl footprint of a coelophysoid theropod or an indeterminate dinosauromorph was found around 1995 near Červený Kostelec in these strata. It was classified as ichnogenus ''Eubrontes''. In 2011, another dinosaur footprint was discovered (in Botanical garden of Prague, but on the stone slab carried from this quarry), this time classified as ichnogenus ''Anomoepus ''Anomoepus'' is the name assigned to several fossil footprints first reported from Early Jurassic beds of the Connecticut River Valley, Massachusetts, USA in 1802.
