Gable Creek Formation
The Gable Creek Formation is a sedimentary rock Geological formation, formation from the Albian age of the Early Cretaceous. The formation is in Wheeler County, Oregon, Wheeler County, Oregon of the United States of America and is intertongued with the similarly aged Hudspeth Formation. The formation mostly consists of fluvial-deltaic Sandstone, sandstones and Conglomerate (geology), conglomerates. Marine fossils can be found throughout the formation including various species of ammonites, clams and other mollusks. The Gable Creek Formation gets its name from Gable Creek, a creek that runs through much of the formation.

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 (geology), 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Turritella
''Turritella'' is a genus of medium-sized sea snails with an Operculum (gastropod), operculum, marine (ocean), marine gastropod mollusc, mollusks in the family Turritellidae.Vos, C.; Gofas, S. (2013). Turritella Lamarck, 1799.

The name ''Turritella'' comes from the Latin word ''turritus'' meaning "turreted" or "towered" and the diminutive suffix ''-ella''.

Natica
''Natica'' is a genus of small to medium-sized predatory sea snails, marine gastropods in the subfamily Naticinae of the family Naticidae, the moon snails. The genus was erected by Giovanni Antonio Scopoli in 1777.Gofas, S. (2011). Natica Scopoli, 1777.

Lunatia
''Lunatia'' is a genus of predatory sea snails, marine gastropod mollusks in the family Naticidae, the moon snails.Bouchet, P. (2012). Lunatia. Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=150577 on 2012-07-12 The species in this genus have been brought in synonymy mostly with ''Euspira'' Torigoe & Inaba (2011) provided a rather arbitrary assignment of species to respectively ''Euspira'' and ''Lunatia'' and this has been at one time uploaded in the WoRMS classification. However this is not based on any in-depth phylogenetic analysis and has proved inconsistent when some closely related European species (e.g. Euspira guillemini, E. macilenta) were then not congeneric. Until a substantiated phylogenetic hypothesis is published for the group, ''Lunatia'' is here considered a junior subjective synonym of ''Euspira'' and all the species accepted under ''Euspira'', following in this Marincowich (1977), Kabat (1991) and t ...

Tragodesmoceras
''Tragodesmoceras'' is a large moderately involute ammonite with deeply embracing whorls that are higher than wide, a steep sided umbilicus and a narrowly rounded venter. Ornament consists of primary ribs that begin at the umbilical shoulder and smaller secondary ribs that begin mid flank. Ribs are sigmodal, periodically thickened and bent forward on the outer flank to cross the venter as chevrons. The suture has a broad trifid lateral lobe. Species include ''Tregodesmoceras clypealoides'' (type), known from western Europe and the U.S., ''Tragodesmosderas bassi'', known from Arizona and Kansas, and ''Tragodesoceras socorroense'' known from Arizona and New Mexico. The related '' Muniericeras'' is more evolute in form, but otherwise similar. References * W.J. Arkell, et al., 1957.
