Gasconadian Stage, the Glossary

Index Gasconadian Stage

The Gasconadian Stage is the 1st stage of the Ordovician geologic period in North America and of the Lower Ordovician Canadian Epoch, coming immediately after the Late Cambrian Trempealeauan and preceding the middle Canadian Demingian Stage.[1]

Cambrian

The Cambrian is the first geological period of the Paleozoic Era, and the Phanerozoic Eon.

Canadian Epoch

The Canadian is the Lower or Early Ordovician in North America.

Clarkoceras

Clarkoceras is a genus of breviconic ellesmerocerid cephalopods, one of only two genera known to have crossed from the Late Cambrian, Trempealeauan, into the Early Ordovician, Gasconadian.

Ectenolites

Ectenolites is a genus of small, slender, cylindrical Ellesmeroceratids that resemble Ellesmeroceras but are smaller and proportionally narrower.

Ellesmeroceras

Ellesmeroceras is the type genus for the Ellesmeroceratidae, a family of primitive nautiloid cephalopods, that is characterized by its small, generally compressed, gradually expanded, orthoconic shell, found in Lower Ordovician marine sediments.

Endocerida

Endocerida is an extinct nautiloid order, a group of cephalopods from the Lower Paleozoic with cone-like deposits in their siphuncle.

New Mexico

New Mexico (Nuevo MéxicoIn Peninsular Spanish, a spelling variant, Méjico, is also used alongside México. According to the Diccionario panhispánico de dudas by Royal Spanish Academy and Association of Academies of the Spanish Language, the spelling version with J is correct; however, the spelling with X is recommended, as it is the one that is used in Mexican Spanish.; Yootó Hahoodzo) is a state in the Southwestern region of the United States.

Ordovician

The Ordovician is a geologic period and system, the second of six periods of the Paleozoic Era.

Tarphycerida

The Tarphycerida were the first of the coiled cephalopods, found in marine sediments from the Lower Ordovician (middle and upper Canad) to the Middle Devonian.

Texas

Texas (Texas or Tejas) is the most populous state in the South Central region of the United States.

Tremadocian

The Tremadocian is the lowest stage of Ordovician. Gasconadian Stage and Tremadocian are Early Ordovician and Ordovician geochronology.

Trempealeauan

The Trempealeauan is the upper or latest stage of the Upper or Late Cambrian in North America, spanning about 4 million years from about 492.5 to 488.3 m.y.a., equivalent to the Fengshanian of China.
