Big guns of the Cambrian Explosion: macroskeletal benthic assemblage in the lower Cambrian Stage 2 of the Olenek Uplift, Arctic Siberia
The basal Cambrian Stage 2 strata of the Olenek Uplift host diverse assemblages of macroscopic fossils, which closely resemble certain small skeletal taxa early reported from this section and typical for the Terreneuvian Epoch. Herein studied macroscopic assemblage includes helcionellid, stenothecid...

| description |
The basal Cambrian Stage 2 strata of the Olenek Uplift host diverse assemblages of macroscopic fossils, which closely resemble certain small skeletal taxa early reported from this section and typical for the Terreneuvian Epoch. Herein studied macroscopic assemblage includes helcionellid, stenothecid and kharkhaniid molluscs, and anabaritids and circothecid hyoliths. Among the assemblage, only anabaritids and some citrcothecid hyoliths exhibit relics of calcite shell, whereas most of the fossils reveal no evidence of rigid biomineralized exoskeleton. Hence, at least these problematic Cambrian organisms had reached macroscopic sizes (up to 35 mm long) and were covered with calcite shells at the very beginning of the Cambrian Age 2. Los estratos basales del Piso cámbrico 2 del Olenek Uplift albergan diversos conjuntos de fósiles macroscópicos, que se asemejan mucho a ciertos pequeños taxones esqueléticos documentados en esta sección y típicos del Terranoviense. En este caso, la asociación macroscópica estudiada incluye moluscos helcionélidos, estenotécidos y kharkhánidos, así como hiolitos de tipo anabarítido y circotécidos. Entre ellos, sólo los anabarítidos y algunos hiolitos circotécidos muestran restos de concha calcítica, mientras que la mayoría de los fósiles carecen de exoesqueleto rígido biomineralizado. Por tanto, al menos estos organismos cámbricos problemáticos habrían alcanzado tamaños macroscópicos (de hasta 35 mm de largo) y estaban cubiertos con conchas calcíticas al principio del Pisp cámbrico 2. |
