Zapsalis
''Zapsalis'' is a genus of dromaeosaurine theropod dinosaurs. It is a tooth taxon, often considered dubious because of the fragmentary nature of the fossils, which include teeth but no other remains. Etymology The generic name is derived from Greek ''za~'', "thorough", and ''psalis'', "pair of scissors". The specific name means "abrading" in Latin. History and classification Fossils of ''Zapsalis'' were first described by American paleontologist Edward Drinker Cope in 1876 but as species of the large carnivorous theropod ''Laelaps'' (now ''Dryptosaurus'').Cope, E. D. (1876). Descriptions of some vertebrate remains from the Fort Union beds of Montana. ''Proceedings of the Academy of natural Sciences of Philadelphia'', 248-261. Cope erected 2 species, ''Laelaps explanatus'' and ''L. laevifrons'', the former based on a collection of 27 teeth and the latter based on a single tooth. It wasn't until later in 1876 that Cope made the genus ''Zapsalis'', with ''Z. abradens'' as the t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saurornitholestes Langstoni
''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 name ...

Judith River Formation
The Judith River Formation is a fossil-bearing geologic formation in Montana, and is part of the Judith River Group. It dates to the Late Cretaceous, between 79 and 75.3 million years ago, corresponding to the "Judithian" land vertebrate age. It was laid down during the same time period as portions of the Two Medicine Formation of MontanaSullivan, R.M. and Lucas, S. G. (2006).

Paronychodon
''Paronychodon'' (meaning "beside claw tooth") was a theropod dinosaur genus. It is a tooth taxon, often considered dubious because of the fragmentary nature of the fossils, which include "buckets" of teeth from many disparate times and places but no other remains, and should be considered a form taxon. The type species, named by Edward Drinker Cope in 1876,Cope, E.D., 1876, "Descriptions of some vertebrate remains from the Fort Union Beds of Montana", ''Proceedings of the Academy of Natural Sciences of Philadelphia'', 28: 248-261 is ''Paronychodon lacustris'', from the Judith River Formation of Montana, dating to 75 million years ago, during the Campanian stage. The holotype is specimen AMNH 3018. It is a tooth about one centimetre long, elongated, recurved, lacking serrations, possessing low vertical ridges and with a D-shaped cross-section, the inner side being flattened. Cope at first thought the tooth belonged to a plesiosaur, but in the same year realised it represented a ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dinosaur Park Formation
The Dinosaur Park Formation is the uppermost member of the Belly River Group (also known as the Judith River Group), a major geologic unit in southern Alberta. It was deposited during the Campanian stage of the Late Cretaceous, between about 76.5 and 74.4 million years ago. It was deposited in alluvial and coastal plain environments, and it is bounded by the nonmarine Oldman Formation below it and the marine Bearpaw Formation above it.Eberth, D.A. 2005. The geology. In: Currie, P.J., and Koppelhus, E.B. (eds), Dinosaur Provincial Park: A Spectacular Ancient Ecosystem Revealed. Indiana University Press: Bloomington and Indianapolis, p.54-82. . The Dinosaur Park Formation contains dense concentrations of dinosaur skeletons, both articulated and disarticulated, which are often found with preserved remains of soft tissues. Remains of other animals such as fish, turtles, and crocodilians, as well as plant remains, are also abundant. The formation has been named after Dinosaur Pr ...

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 ce ...

Derek Larson
Derek is a masculine given name. It is the English language short form of ''Diederik'', the Low Franconian form of the name Theodoric. Theodoric is an old Germanic name with an original meaning of "people- ruler". Common variants of the name are Derrek, Derick, Dereck, Derrick, and Deric. Low German and Dutch short forms of Diederik are Dik, Dirck, and Dirk. History The English form of the name arises in the 15th century, via import from the Low Countries. The native English (Anglo-Saxon) form of the name was ''Deoric'' or ''Deodric'', from Old English ''Þēodrīc'', but this name had fallen out of use in the medieval period. During the Late Middle Ages, there was intense contact between the territories adjacent to the North Sea, in particular due to the activities of the Hanseatic League. As a result, there was a lot of cross-pollination between Low German, Dutch, English, Danish and Norwegian. The given name ''Derk'' is found in records of the Low Countries from the ...

Julia Sankey
Julia is usually a feminine given name. It is a Latinate feminine form of the name Julio and Julius. (For further details on etymology, see the Wiktionary entry "Julius".) The given name ''Julia'' had been in use throughout Late Antiquity (e.g. Julia of Corsica) but became rare during the Middle Ages, and was revived only with the Italian Renaissance. It became common in the English-speaking world only in the 18th century. Today, it is frequently used throughout the world. Statistics Julia was the 10th most popular name for girls born in the United States in 2007 and the 88th most popular name for women in the 1990 census there. It has been among the top 150 names given to girls in the United States for the past 100 years. It was the 89th most popular name for girls born in England and Wales in 2007; the 94th most popular name for girls born in Scotland in 2007; the 13th most popular name for girls born in Spain in 2006; the 5th most popular name for girls born in Sweden ...

Dromaeosaurus
''Dromaeosaurus'' (, "running lizard") is a genus of dromaeosaurid theropod dinosaur which lived during the Late Cretaceous period (middle late Campanian and Maastrichtian), sometime between 80 and 69 million years ago, in Alberta, Canada and the western United States. The type species is ''Dromaeosaurus albertensis'', which was described by William Diller Matthew and Barnum Brown in 1922. Its fossils were unearthed in the Dinosaur Park Formation. Teeth attributed to this genus have been found in the Prince Creek Formation. ''Dromaeosaurus'' is the type genus of both Dromaeosauridae and Dromaeosaurinae, which include many genera with similar characteristics to ''Dromaeosaurus'' such as possibly its closest relative ''Dakotaraptor''. ''Dromaeosaurus'' was heavily built, more so than other dromaeosaurs that are similar in size, like ''Velociraptor''. Discovery and naming Despite receiving widespread attention in popular books on dinosaurs, and the usage of a complete mounted skelet ...

Aublysodon
''Aublysodon'' (“backwards-flowing tooth") is a genus of carnivorous dinosaurs known only from the Judith River Formation in Montana, which has been dated to the late Campanian age of the late Cretaceous period (about 75 million years ago). The only currently recognized species, ''Aublysodon mirandus'', was named by paleontologist Joseph Leidy in 1868. It is now considered dubious, because the type specimen consists only of an isolated premaxillary (front) tooth. Although this specimen is now lost, similar teeth have been found in many US states, western Canada, and Asia. These teeth almost certainly belong to juvenile tyrannosaurine tyrannosaurids, but most have not been identified to species level. However, it is likely that the type tooth (and therefore the name ''Aublysodon mirandus'' itself) belongs to one of the species in the genus ''Daspletosaurus'', which was present in contemporary formations, and which matches specific details of the original tooth. The synapomorphies ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deinodon
''Deinodon'' (Greek for "terrible tooth") is a dubious tyrannosaurid dinosaur genus containing a single species, ''Deinodon horridus''. ''D. horridus'' is known only from a set of teeth found in the Late Cretaceous Judith River Formation of Montana and named by paleontologist Joseph Leidy in 1856.Leidy, J. (1856). "Notices of the remains of extinct reptiles and fishes, discovered by Dr. F.V. Hayden in the badlands of the Judith River, Nebraska Territory." ''Proc. Acad. Nat. Sci.'', 8(2): 72. These were the first tyrannosaurid remains to be described and had been collected by Ferdinand Vandeveer Hayden. The teeth of ''Deinodon'' were slightly heterodont, and the holotype of ''Aublysodon'' can probably be assigned to ''Deinodon''. History and classification It is likely that the fossilized teeth of ''D. horridus'' belonged to the dinosaur later identified as ''Gorgosaurus libratus''. In a 1922 study, William Diller Matthew & Barnum Brown found that the teeth of ''D. horridus'' and ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
