Genus PLATYSOLENITES

PLATYSOLENITES Eichwald, 1860

Type species: Platysolenites antiquissimus Eichwald, 1860; OD(M).

Platysolenites Eichwald, 1860 (*1086), p. 677. Platysoleniten Pander, 1856 (*2332), explan. of plate 3, fig. 17 on p. 84 (nom. vernac.).

Yanichevskyites Sokolov. 1965 (*3016), p. 82, 84 (name available, ICZN Art. 13 (ii), not described, but refer

ence given to previous description); type species: Serpulites? petropolitanus Yanishevskiy, 1926 (*3415), p. 112; OD(M).

Elongate, straight, cylindrical tubes that may be flattened in preservation, 1 mm to 3 mm in breadth and up to 30 mm or more in length; wall thick, up to 0.9 mm in thickness, of agglutinated small quartz grains, surface with widely spaced transverse grooves or wrin­kles; aperture at the open ends of the tube. L. Cambrian; USSR; Poland; Norway; USA: California.

 

Remarks: Platysolenites has been variously placed with the annelids or echinoderms but was redescribed as a foraminifer by FØyn and Glaessner (1979, *1168, p. 30). They credited the genus to Pander (1851), but we are unable to locate a validation of this name by Pander. Eichwald (1860, *1086, p. 677) described the genus and species, citing "Platysolenites Pand.," giving the reference "Pander die Fische des silurischen Systems 1. c." Pander's "Monographie der fossilen Fische des silurischen Systems der Russisch-Baltischen Gouvernements" was published in 1856 rather than 1851; his plate 3, fig. 17 refers to Platysolenites only in the vernacular, hence has no standing in zoological nomenclature.
