Geological Formation
A geological formation, or simply formation, is a body of rock having a consistent set of physical characteristics ( lithology) that distinguishes it from adjacent bodies of rock, and which occupies a particular position in the layers of rock exposed in a geographical region (the stratigraphic column). It is the fundamental unit of lithostratigraphy, the study of strata or rock layers. A formation must be large enough that it can be mapped at the surface or traced in the subsurface. Formations are otherwise not defined by the thickness of their rock strata, which can vary widely. They are usually, but not universally, tabular in form. They may consist of a single lithology (rock type), or of alternating beds of two or more lithologies, or even a heterogeneous mixture of lithologies, so long as this distinguishes them from adjacent bodies of rock. The concept of a geologic formation goes back to the beginnings of modern scientific geology. The term was used by Abraham Gottlob Wer ...

Eubrontes
''Eubrontes'' is the name of fossilised dinosaur footprints dating from the Late Triassic and Early Jurassic. They have been identified from France, Poland, Slovakia, Czech Republic, Italy, Spain, Sweden, Australia (Queensland), USA, India and China. ''Eubrontes'' is the name of the footprints, identified by their shape, and not of the genus or genera that made them, which is as yet unknown but is presumed to be similar to ''Coelophysis'' or ''Dilophosaurus''. They are most famous for their discovery in the Connecticut River Valley of Massachusetts in the early 19th century. They, among other footprints, were the first known non-avian dinosaur tracks to be discovered in North America, though they were initially thought to have been made by large birds. Discovery and identity The footprints were first described by Edward Hitchcock, a professor of Amherst College, who thought they were made by a large bird. He originally assigned them to ichnotaxon ''Ornithichnites'' in 1836, then ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Geologic Formations Of China
Geology () is a branch of natural science concerned with Earth and other astronomical objects, the features or rocks of which it is composed, and the processes by which they change over time. Modern geology significantly overlaps all other Earth sciences, including hydrology, and so is treated as one major aspect of integrated Earth system science and planetary science. Geology describes the structure of the Earth on and beneath its surface, and the processes that have shaped that structure. It also provides tools to determine the relative and absolute ages of rocks found in a given location, and also to describe the histories of those rocks. By combining these tools, geologists are able to chronicle the geological history of the Earth as a whole, and also to demonstrate the age of the Earth. Geology provides the primary evidence for plate tectonics, the evolutionary history of life, and the Earth's past climates. Geologists broadly study the properties and processes of E ...

Minisauripus
''Minisauripus'' is an ichnogenus of dinosaur footprint. ''Minisauripus'' is regarded as the smallest pre KT-extinction dinosaur ever discovered. It was less than 20 cm (7.8 inches) long. Its footprints have been found in the Jinju Formation and the Feitianshan Formation The Feitianshan Formation is a geological formation Formation may refer to: Linguistics * Back-formation, the process of creating a new lexeme by removing or affixes * Word formation, the creation of a new word by adding affixes Mathematics a ..., a low-energy lake formation. Its footprints were found within the vicinity of those of the larger '' Jialingpus''. Identification Based on the trackways, ''Minisauripus'' was possibly a hatchling theropod. However, ichnopalaeontologists aren't sure if it belonged to an actual juvenile dinosaur. The ''Minisauripus'' tracks show three distinct toes, unlike the tracks of similar-sized small dromaeosaurids such as '' Dromaeosauripus rarus'', which are didactyl, with t ...

''Minisauripus'' is an ichnogenus of dinosaur footprint. ''Minisauripus'' is regarded as the smallest pre KT-extinction dinosaur ever discovered. It was less than 20 cm (7.8 inches) long. Its footprints have been found in the Jinju Formation and the Feitianshan Formation, a low-energy lake formation. Its footprints were found within the vicinity of those of the larger '' Jialingpus''. Identification Based on the trackways, ''Minisauripus'' was possibly a hatchling theropod. However, ichnopalaeontologists aren't sure if it belonged to an actual juvenile dinosaur. The ''Minisauripus'' tracks show three distinct toes, unlike the tracks of similar-sized small dromaeosaurids such as '' Dromaeosauripus rarus'', which are didactyl, with the "killer claw" on the inner toe being held off the ground and thus not preserved in the trackway.

Jialingpus
''Jialingpus'' is an ichnogenus of dinosaur, likely a theropod. Its footprints have been found in the Feitianshan Formation, a low-energy lake formation. Holotype is SCFP-24, which was found in Late Jurassic ( Oxfordian)-aged Yuechi tracksite at Huanglong, China.

Early Cretaceous
The Early Cretaceous ( geochronological name) or the Lower Cretaceous (chronostratigraphic name), is the earlier or lower of the two major divisions of the Cretaceous. It is usually considered to stretch from 145 Ma to 100.5 Ma. Geology Proposals for the exact age of the Barremian-Aptian boundary ranged from 126 to 117 Ma until recently (as of 2019), but based on drillholes in Svalbard the defining early Aptian Oceanic Anoxic Event 1a (OAE1a) was carbon isotope dated to 123.1±0.3 Ma, limiting the possible range for the boundary to c. 122–121 Ma. There is a possible link between this anoxic event and a series of Early Cretaceous large igneous provinces (LIP). The Ontong Java-Manihiki-Hikurangi large igneous province, emplaced in the South Pacific at c. 120 Ma, is by far the largest LIP in Earth's history. The Ontong Java Plateau today covers an area of 1,860,000 km2. In the Indian Ocean another LIP began to form at c. 120 Ma, the Kerguelen P ...

Ichnotaxon
An ichnotaxon (plural ichnotaxa) is "a taxon based on the fossilized work of an organism", i.e. the non-human equivalent of an artifact. ''Ichnotaxa'' comes from the Greek ίχνος, ''ichnos'' meaning ''track'' and ταξις, ''taxis'' meaning ''ordering''.Definition o'ichno'at dictionary.com. Ichnotaxa are names used to identify and distinguish morphologically distinctive ichnofossils, more commonly known as trace fossils. They are assigned genus and species ranks by ichnologists, much like organisms in Linnaean taxonomy. These are known as ichnogenera and ichnospecies, respectively. "Ichnogenus" and "ichnospecies" are commonly abbreviated as "igen." and "isp.". The binomial names of ichnospecies and their genera are to be written in italics. Most researchers classify trace fossils only as far as the ichnogenus rank, based upon trace fossils that resemble each other in morphology but have subtle differences. Some authors have constructed detailed hierarchies up to ichnosupe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
