Brontomerus
''Brontomerus'' (from Greek ''bronte'' meaning "thunder", and ''merós'' meaning "thigh") is a possibly dubious genus of camarasauromorph sauropod which lived during the early Cretaceous (Aptian or Albian age, approximately 110 million years ago). It was named in 2011 and the type species is ''Brontomerus mcintoshi''. It is probably a fairly basal camarasauromorph, though the taxon is difficult to resolve due to incompleteness of the material. It is most remarkable for its unusual hipbones, which would have supported the largest thigh muscles, proportionally, of any known sauropod. The specific name is in honor of physicist and North American sauropod expert John "Jack" Stanton McIntosh. Description ''Brontomerus'' is known from two fragmentary specimens differing in size, likely a juvenile and an adult. The researchers speculate that the adult may have been the mother of the juvenile. The type specimen, OMNH 66430, is represented by the left ilium of the smaller individual. ...

Somphospondyli
Somphospondyli is an extinct clade of titanosauriform sauropods that lived from the Late Jurassic until the end of the Late Cretaceous, comprising all titanosauriforms more closely related to Titanosauria proper than Brachiosauridae. The remains of somphospondylans have been discovered in all six continents. Classification The group has officially been defined under the PhyloCode as the largest clade containing ''Saltasaurus loricatus'', but not ''Giraffatitan brancai.'' Features found as diagnostic of this clade by Mannion ''et al.'' (2013) include the possession of at least 15 cervical vertebrae; a bevelled radius bone end; sacral vertebrae with camellate internal texture; convex posterior articular surfaces of middle to posterior caudal vertebrae; biconvex distal caudal vertebrae; humerus anterolateral corner "squared"; among multiple others. The following cladogram depicts the reference phylogeny used to defined Somphospondlyi under the PhyloCode The ''International Cod ...

Mike Taylor (paleontologist)
Michael Paul Taylor (born 12 March 1968) is a British computer programmer with a Ph.D. in palaeontology. To date, he has published 18 paleontological papers and is co-credited with naming three genera of dinosaur (''Xenoposeidon'' in 2007 with Darren Naish, ''Brontomerus'' in 2011 with Matt J. Wedel and Richard Cifeli, and ''Haestasaurus'' in 2015 with Paul Upchurch and Phil Mannion). Along with paleontologists Darren Naish and Matt Wedel, he founded the paleontology blog ''Sauropod Vertebra Picture of the Week'', where he blogs as Mike Taylor. He lives in Ruardean Ruardean is a village in the Forest of Dean, Gloucestershire, England, to the North West of Cinderford.

Cedar Mountain Formation
The Cedar Mountain Formation is the name given to a distinctive sedimentary geologic formation in eastern Utah, spanning most of the early and mid-Cretaceous. The formation was named for Cedar Mountain in northern Emery County, Utah, where William Lee Stokes first studied the exposures in 1944. Geology The formation occurs between the underlying Morrison Formation and overlying Naturita Formation (sometimes formerly called the Dakota Formation). It is composed of non-marine sediments, that is, sediments deposited in rivers, lakes and on flood plains. Based on various fossils and radiometric dates, the Cedar Mountain Formation was deposited during the last half of the Early Cretaceous Epoch, about 127 - 98 million years ago (mya). It has lithography similar to the Burro Canyon Formation in the region. Dinosaur fossils occur throughout the formation, but their study has only occurred since the early 1990s. The dinosaurs in the lower part of the formation differ from those in th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Autapomorphy
In phylogenetics, an autapomorphy is a distinctive feature, known as a derived trait, that is unique to a given taxon. That is, it is found only in one taxon, but not found in any others or outgroup taxa, not even those most closely related to the focal taxon (which may be a species, family or in general any clade). It can therefore be considered an apomorphy in relation to a single taxon. The word ''autapomorphy'', first introduced in 1950 by German entomologist Willi Hennig, is derived from the Greek words αὐτός, ''autos'' "self"; ἀπό, ''apo'' "away from"; and μορφή, ''morphḗ'' = "shape". Discussion Because autapomorphies are only present in a single taxon, they do not convey information about relationship. Therefore, autapomorphies are not useful to infer phylogenetic relationships. However, autapomorphy, like synapomorphy and plesiomorphy is a relative concept depending on the taxon in question. An autapomorphy at a given level may well be a synapomorphy a ...

Cladistics
Cladistics (; ) is an approach to biological classification in which organisms are categorized in groups (" clades") based on hypotheses of most recent common ancestry. The evidence for hypothesized relationships is typically shared derived characteristics ( synapomorphies'')'' that are not present in more distant groups and ancestors. However, from an empirical perspective, common ancestors are inferences based on a cladistic hypothesis of relationships of taxa whose character states can be observed. Theoretically, a last common ancestor and all its descendants constitute a (minimal) clade. Importantly, all descendants stay in their overarching ancestral clade. For example, if the terms ''worms'' or ''fishes'' were used within a ''strict'' cladistic framework, these terms would include humans. Many of these terms are normally used paraphyletically, outside of cladistics, e.g. as a ' grade', which are fruitless to precisely delineate, especially when including extinct species. ...

Grand County, Utah
Grand County is a county on the east central edge of the U.S. state of Utah, United States. As of the 2010 United States Census, the population was 9,225. Its county seat and largest city is Moab. History Evidence of indigenous occupation up to 10,000BCE has been previously discovered in Grand County. The present city of Moab is the site of pueblo farming communities of the 11th and 12th centuries. These groups had already vanished from the area when the first European explorers entered the country, with nomadic Ute tribes inhabiting the area at the time of contact. The European-based settlement of the area began with the arrival of Mormon pioneers in 1847. By 1855 they had sent missionary settlers into eastern Utah Territory. An Elk Mountain Mission was established but closed after a few months due to Indian raids. For several decades after that, the future Moab area (known as "Spanish Valley") was visited only by trappers and prospectors. Permanent settlement began in 1877. ...
