Remarks about age Poleta formation and its biozonation
[edit]The Poleta formation is contains fragments of two Laurentian biozones: the upper part of the Nevadella Zone, and also the smaller lower part of Bonnia-Olenellus Zone (= Olenellus Zone). The Nevadella Zone is correlated with the Atdabanian and lowermost Botomian, the Bonnia-Olenellus Zone is correlated with the Botomian and Toyonian Stages. The beds of Poleta formation with its helicoplacoids are in limit of the Nevadella Zone and aged upper Atdabanian. Greenland Sirius Passet lagerstatte is correlated to Laurentian Nevadella Zone.
Or now it is considered that all Poleta formation is Olenellus Zone, Dyeran?

The base of the Poleta Fm. date to the Olenellus Zone and aged Dyeran Stage. It is the private point of view of Adam M. English and Loren E. Babcock or it is fact which is recognized by the majority of researchers? What happened? The volume of the Olenellus Zone and Dyeran has been increased or correlation of the Poleta Formation has been reconsidered? As far as I know it is the first publication of such point of view, therefore this idea is not tested by the scientific community and possible can be not considered as reliable and priority.

Stewart Hollingsworth includes lower Poleta Formation and its index trilobites into Montezuman Stage. http://gsa.confex.com/gsa/2008CD/finalprogram/abstract_134944.htm Aleksey (Alnagov (talk) 16:18, 8 June 2010 (UTC))
- On re-inspection, the authors state:
| “ | Nevadia parvoconica (Fig. 4b, 4c) is the most common trilobite in the lower 88 m of the middle member of the Poleta Formation. Its presence indicates a correlation with the Nevadella trilobite zone (Cambrian Stage 3, equivalent to Montezuman Stage of historic Laurentian nomenclature; Hollingsworth, 2005; Fig. 3). Nevadella eucharis is the most common trilobite above 88 m and its presence indicates a correlation with the Olenellus trilobite zone (Cambrian Stage 3, equivalent to the Dyeran Stage of historic Laurentian nomenclature, Hollingsworth, 2005; Fig. 3). | ” |
