The early Cambrian helcionelloid mollusc Anabarella Vostokova

  title={The early Cambrian helcionelloid mollusc Anabarella Vostokova},
  author={Alexander P. Gubanov and John S. Peel},
One of the oldest known helcionelloid molluscs, Anabarella Vostokova, is redescribed on the basis of type material from the lower Cambrian of north Siberia. Published records of the type species, Anabarella plana Vostokova, show a very wide range in morphology, but studies of variation through ontogeny and in taphonomy confirm assignment to a single variable species. Other described species are reviewed.

Shell microstructures of the helcionelloid mollusc Anabarella australis from the lower Cambrian (Series 2) Xinji Formation of North China
Although various types of shell microstructures are documented from Cambrian molluscs, the precise organization and mineralogical composition of Terreneuvian molluscs are relatively unknown.
Totoralia, a new conical-shaped mollusk from the middle Cambrian of western Argentina
The new genus Totoralia from the late middle Cambrian of El Totoral (Mendoza Province, western Argentina) is described, a delicate, high, bilaterally symmetrical cone with a sub-central apex and five to seven prominent comarginal corrugations that resembles the Cambrian helcionellids Scenella and Palaeacmaea.
Early Cambrian Mollusc Watsonella crosbyi: A Potential GSSP Index Fossil for the Base of the Cambrian Stage 2

Oelandiella, the earliest Cambrian helcionelloid mollusc from Siberia
The helcionelloid molluscs Oelandiella korobkoviO. sibirica Vostokova are redescribed on the basis of type material from the lowest Cambrian of northern Siberia. Oelandiella is reinstated as a
Paleoecology and distribution of the Early Cambrian rostroconch Watsonella crosbyi Grabau
Watsonella crosbyi Grabau, 1900, a senior synonym of Heraultipegma varensalense (Cobbold, 1935) and H. yannense He and Yang, 1982, is the oldest known rostroconch. The species ranges through most of
Biostratigraphy of the Vendian-Cambrian beds and the lower Cambrian boundary in Siberia
Abstract General agreement exists that the position of the base of the Cambrian (Precambrian–Cambrian boundary) should coincide with a biostratigraphic marker that can be widely traced and is linked
Age constraints from small shelly fossils on the early Cambrian terminal Cadomian Phase in Iberia
Abstract The records of biotic and biogeochemical events around the Proterozoic-Cambrian transition are well preserved in sedimentary rock successions in Iberia. Until recently, sparsely
Cladistic perspectives on early bivalve evolution
Parsimony analysis suggests derivation of the Bivalvia from monoplacophorans rather than from rostroconchs, and indicates that a phylogenetic classification of the Heteroconchia can be achieved by erecting the superorder Nuculaniformii nov.
