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 ...

Odontochile
''Odontochile'' is a genus of trilobites in the order Phacopida, family Dalmanitidae.Struve, W. Suborder Phacopina, p. O471-O472. ''in'' Moore, R.C. (ed.). Treatise on Invertebrate Paleontology. Part O – Arthropoda (Trilobitomorpha). 1959 These trilobites were fast-moving low-level epifauna and detritivore. They lived in the Devonian period, from 414 to 391 million years ago. Distribution Silurian of China; Silurian to Devonian of Australia and the United States; Devonian of Algeria, Canada, the Czech Republic, France, Germany, Kazakhstan, Morocco and Spain. Description ''Odontochile'' is genus of trilobites with a large (about long), moderately vaulted exoskeleton with an inverted egg-shaped outline (about 1.6× longer than wide). Its headshield (or cephalon) is semicircular, with long (genal) spines extending from the side of the cephalon back to the tailshield (or pygidium). The frontal margin of the cephalon is semicircular to parabolic, and lacks an anterior exten ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Climatius
''Climatius'' (from el, κλίμα , 'gradation') is an extinct genus of spiny shark. Fossils have been found in both Europe and North America. ''Climatius'' was an active swimmer, judging from its powerful caudal fin and abundant stabilizing fins, and probably preyed on other fish and crustaceans. Its lower jaw was lined with sharp teeth which were replaced when worn, but the upper jaw had no teeth. It had large eyes, suggesting that it hunted by sight. It was a small fish, at , and to discourage predators, ''Climatius'' sported fifteen sharp spines. There was one spine each on the paired pelvic and pectoral fins, and on the aingle anal and two dorsal fins, and a four pairs without fins on the fish's underside.
