Horseshoe Canyon Formation
The Horseshoe Canyon Formation is a stratigraphic unit of the Western Canada Sedimentary Basin in southwestern Alberta. It takes its name from Horseshoe Canyon, an area of badlands near Drumheller. The Horseshoe Canyon Formation is part of the Edmonton Group and is up to thick. It is of Late Cretaceous age, Campanian to early Maastrichtian stage (Edmontonian Land-Mammal Age), and is composed of mudstone, sandstone, carbonaceous shales, and coal seams. A variety of depositional environments are represented in the succession, including floodplains, estuarine channels, and coal swamps, which have yielded a diversity of fossil material. Tidally-influenced estuarine point bar deposits are easily recognizable as Inclined Heterolithic Stratification (IHS). Brackish-water trace fossil assemblages occur within these bar deposits and demonstrate periodic incursion of marine waters into the estuaries. The Horseshoe Canyon Formation crops out extensively in the area around Drumheller, as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dromaeosauridae
Dromaeosauridae () is a family of feathered theropod dinosaurs. They were generally small to medium-sized feathered carnivores that flourished in the Cretaceous Period. The name Dromaeosauridae means 'running lizards', from Greek ('), meaning 'runner', and ('), meaning 'lizard'. In informal usage, they are often called raptors (after ''Velociraptor''), a term popularized by the film ''Jurassic Park''; a few types include the term "raptor" directly in their name and have come to emphasize their bird-like appearance and speculated bird-like behavior. Dromaeosaurid fossils have been found across the globe in North America, Europe, Africa, Asia, South America and Antarctica, with some fossils giving credence to the possibility that they inhabited Australia as well. They first appeared in the mid-Jurassic Period (late Bathonian stage, about 167 million years ago) and survived until the end of the Cretaceous (Maastrichtian stage, 66 ma), existing until the Cretaceous–Paleogene ...

Saurornitholestinae
Saurornitholestinae is a subfamily of the theropod group Dromaeosauridae. The saurornitholestines currently include three monotypic genera: '' Atrociraptor marshalli'', ''Bambiraptor feinbergi'', and ''Saurornitholestes langstoni''. All are medium-sized dromaeosaurs from the Late Cretaceous of western North America. The group was originally recognized by Longrich and Currie as the sister taxon to a clade formed by the Dromaeosaurinae and Velociraptorinae. However, not all phylogenetic analyses recover this group and/or with the same proposed genera. Classification Below are the results for the Eudromaeosauria phylogeny based on the phylogenetic analysis conducted by Jasinski and colleagues in 2020 during the description of ''Dineobellator''. The group was recovered, but this time with the exclusion of '' Bambiraptor'': See also * Timeline of dromaeosaurid research This timeline of dromaeosaurid research is a chronological listing of events in the history of paleontology focu ...

Timeline Of Dromaeosaurid Research
This timeline of dromaeosaurid research is a chronological listing of events in the history of paleontology focused on the dromaeosaurids, a group of sickle-clawed, bird-like theropod dinosaurs including animals like ''Velociraptor''. Since the Native Americans of Montana used the sediments of the Cloverly Formation to produce pigments, they may have encountered remains of the dromaeosaurid ''Deinonychus'' hundreds of years before these fossils came to the attention of formally trained scientists. In 1922 Matthew and Brown named the new genus and species '' Dromaeosaurus albertensis'', considering it a new type within the family Deinodontidae, a now-defunct family name that once applied to the tyrannosaurs. Not long after, ''Velociraptor'' was discovered in Mongolia by the Central Asiatic Expedition. Dromaeosaur research was fairly quiet until the 1960s, when John Ostrom described the new genus and species ''Deinonychus antirrhopus''. This discovery played a major role in sett ...

Acheroraptor
''Acheroraptor'' is an extinct genus of dromaeosaurid theropod dinosaur known from the latest Maastrichtian Hell Creek Formation of Montana, United States. It contains a single species, ''Acheroraptor temertyorum''. ''A. temertyorum'' is one of the two geologically youngest known species of dromaeosaurids, the other being ''Dakotaraptor'', which is also known from Hell Creek. A basal cousin of ''Velociraptor'', ''Acheroraptor'' is known from upper and lower jaw material. Discovery and naming ''Acheroraptor'' was first described and named by David C. Evans, Derek W. Larson and Philip J. Currie in 2013 and the type species is ''Acheroraptor temertyorum''. The generic name is derived from the Greek Ἀχέρων, ''Acheron'', "underworld", in reference to the provenance from the Hell Creek Formation, and the Latin ''raptor'', "thief". The specific name honours James and Louise Temerty, the chairman of Northland Power and the ROM Board of Governors and his wife, who have suppor ...

Saurornitholestes
''Saurornitholestes'' ("lizard-bird thief") is a genus of carnivorous dromaeosaurid theropod dinosaur from the late Cretaceous of Canada (Alberta) and the United States (Montana, New Mexico, Alabama, North Carolina, and South Carolina). Two species have been named: ''Saurornitholestes langstoni'' in 1978 and ''Saurornitholestes sullivani'' in 2015. ''Saurornitholestes'' was a small bipedal meat-eating dinosaur, equipped with a sickle-claw on the foot. Discovery and naming In 1974 Canadian amateur paleontologist Irene Vanderloh discovered the skeleton of a small theropod near Steveville in Alberta. She showed it to John Storer of the Provincial Museum of Alberta, who brought it to the attention of Hans-Dieter Sues. In 1978 Sues named and described the specimen as the type species ''Saurornitholestes langstoni''. The generic name is in reference to the Saurornithoididae, due to the resemblance with this group that is today seen as part of the Troodontidae, and combines their nam ...

Velociraptorinae
Velociraptorinae is a subfamily of the theropod group Dromaeosauridae. The earliest velociraptorines are probably ''Nuthetes'' from the United Kingdom, and possibly ''Deinonychus'' from North America. However, several indeterminate velociraptorines have also been discovered, dating to the Kimmeridgian stage, in the Late Jurassic Period. These fossils were discovered in the Langenberg quarry, Oker near Goslar, Germany.van der Lubbe, T., Richter, U. and Knotschke, N. (2009).Velociraptorine dromaeosaurid teeth from the Kimmeridgian (Late Jurassic) of Germany" ''Acta Palaeontologica Polonica'', 54(3): 401-408. Description While most velociraptorines were generally small animals, at least one species may have achieved gigantic sizes comparable to those found among the dromaeosaurines. So far, this unnamed giant velociraptorine is known only from isolated teeth found on the Isle of Wight, England. The teeth belong to an animal the size of dromaeosaurines of the genus ''Utahraptor'', but ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Philip J
Philip, also Phillip, is a male given name, derived from the Greek (''Philippos'', lit. "horse-loving" or "fond of horses"), from a compound of (''philos'', "dear", "loved", "loving") and (''hippos'', "horse"). Prominent Philips who popularized the name include kings of Macedonia and one of the apostles of early Christianity. ''Philip'' has many alternative spellings. One derivation often used as a surname is Phillips. It was also found during ancient Greek times with two Ps as Philippides and Philippos. It has many diminutive (or even hypocoristic) forms including Phil, Philly, Lip, Pip, Pep or Peps. There are also feminine forms such as Philippine and Philippa. Antiquity Kings of Macedon * Philip I of Macedon * Philip II of Macedon, father of Alexander the Great * Philip III of Macedon, half-brother of Alexander the Great * Philip IV of Macedon * Philip V of Macedon New Testament * Philip the Apostle * Philip the Evangelist Others * Philippus of Croton (c. 6th cent ...
