Cordosphaeridium inodes ssp. longipes
Cordosphaeridium inodes ssp. Iongipes Hansen, 1977
Holotype: Hansen 1977: fig. 17 E
Locus typicus: TUBA 13, Copenhagen, Denmark
Stratum typicum: Xenicodinium lubricum Zonule (Danian)
Age: Early Paleocene
Diagnosis: Hansen 1977, p. 17: Cordosphaeridium inodes (Klumpp 1953) ssp. longpipes
Cordosphaeridium inodes (Klumpp 1953) with an antapical process longer than all other processes.
Description: Hansen 1977, p. 17: Cordosphaeridium inodes (Klumpp 1953) ssp. longpipes
Central body ovoid and strongly fibrous. The periphragm consistsof numerous 0.2-0.4 Ám thick anastomosing fibres. The endophragm seems almost without structures. Processes strongly fibrous and taeniate except the antapical process, which is circular in cross-section. Distally the fibres are split up into single fibres or bundles of fibres. They may be branched, or in few cases fenestrate. Processesclearly arranged in 3 circles corresponding to the precingular-, cingular- and postcingular regions. In the cingular region processes may be placed on low thickenings of the periphragm. Endophragm extruded into the base of the antapical process. Archeopyle type P, generally enlarged. Operculum typically becomes completelydetached.
Stratigraphical occurence: TUBA 13: from 4 to 48.5 m above the Maastrichtian/Danian boundary. Dania: 10 m above the Maastrichtian/Danian boundary. Kjolby GÕrd: from 0.05 m above the Maastrichtian/Danian boundary (upper part of a complex marl layer) to the top of the section. Localities of Skovvav Bro, Karleby Klint, RÕsted, Tustrup Klausholm. California: Upper Dos Palos Shale (Upper Moreno Formation), Danian.
