Benthic zone

The benthic zone is the ecological region at the lowest level of a body of water such as an ocean, lake, or stream, including the sediment surface and some sub-surface layers.

See Plectronocerida and Benthic zone

Cambrian

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

See Plectronocerida and Cambrian

Cephalopod

A cephalopod is any member of the molluscan class Cephalopoda (Greek plural κεφαλόποδες,; "head-feet") such as a squid, octopus, cuttlefish, or nautilus.

See Plectronocerida and Cephalopod

Discosorida

Discosorida are an order of cephalopods that lived from the beginning of the Middle Ordovician, through the Silurian, and into the Devonian.

See Plectronocerida and Discosorida

Ellesmerocerida

The Ellesmerocerida is an order of primitive cephalopods belonging to the subclass Nautiloidea with a widespread distribution that lived during the Late Cambrian and Ordovician. Plectronocerida and Ellesmerocerida are Cambrian first appearances and Paraphyletic groups.

See Plectronocerida and Ellesmerocerida

Franconian (stage)

The Franconian is the middle stage of the Upper or Late Cambrian in North America, equivalent to the Chinese Changshanian with a span of nearly 4.5 million years, from about 497 to 492.5 Ma.

See Plectronocerida and Franconian (stage)

Furongian

The Furongian is the fourth and final epoch and series of the Cambrian.

See Plectronocerida and Furongian

Jiagouceras

Jiagouceras is a genus of early primitive cephalopods from the Upper Cambrian of China, assigned to the Plectronoceratidae.

See Plectronocerida and Jiagouceras

Ordovician

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

See Plectronocerida and Ordovician

Paleoceras

Paleoceras is a genus of fossil cephalopods from the Upper Cambrian.

See Plectronocerida and Paleoceras

Paraplectronoceras

Paraplectronoceras is a genus of very early nautiloids from the middle Late Cambrian, named by Chen and Qi, 1979, type species Paraplectronoceras pyriforme, for small, endogastrically curved forms found in the upper Yenchou and Wanwankou members of the Fengshan Formation of northeastern China.

See Plectronocerida and Paraplectronoceras

Phragmocone

The phragmocone is the chambered portion of the shell of a cephalopod.

See Plectronocerida and Phragmocone

Plectronoceras

Plectronoceras is the earliest known shelled cephalopod, dating to the Late Cambrian.

See Plectronocerida and Plectronoceras

Plectronocerida

Plectronocerida is a primitive order from which subsequent cephalopod orders are ultimately derived. Plectronocerida and Plectronocerida are Cambrian animals of Asia, Cambrian animals of North America, Cambrian first appearances, Furongian extinctions, Paraphyletic groups, Prehistoric cephalopod orders and Prehistoric nautiloids.

See Plectronocerida and Plectronocerida

Protactinocerida

Protactinocerida is a proposed order of Late Cambrian nautiloid cephalopods. Plectronocerida and Protactinocerida are Furongian extinctions, Prehistoric cephalopod orders and Prehistoric nautiloids.

See Plectronocerida and Protactinocerida

Siphuncle

The siphuncle is a strand of tissue passing longitudinally through the shell of a cephalopod mollusk.

See Plectronocerida and Siphuncle

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.

See Plectronocerida and Trempealeauan

Yanhecerida

Yanhecerida is a small order of Late Cambrian (mid-Stage 10) nautiloid cephalopods. Plectronocerida and Yanhecerida are Furongian extinctions, Prehistoric cephalopod orders and Prehistoric nautiloids.
