fossilrange and spatial distribution

The range indicated in the earlier version, the entire Cambrian (542-488 Mya) is much too wide, and includes the Fortunian and Tomotian (542-526 Mya), which is before the first trilobite recorded, and the Middle and Upper Cambrian (513-488 Mya), which is after the latest occurence of any Olenellina. I have some difficulty pinpointing the exact age of the "Middle and Upper Olenellus-zone", that the Treatise indicates for Olenellus (Mesonacis), but I believe it is contained within the Botonian (516-513 Mya). This is consistent with the age given for the Emu Bay Lagerstaette in Australia.

The spatial distribution indicated in the earlier version (Wales and Australia) is much to narrow, since the Treatise mentions North-America (excluding Greenland) and United Kingdom (North-Western Scotland). I did not check if Wales and Australia are correct citations, so I will maintain them, but add the spatial distribution from the Treatise. Dwergenpaartje (talk) 14:41, 9 March 2012 (UTC)[reply]

I asked the original creator of the page to explain the source for the supposed occurence of Mesonacis in Australia and Wales. Regrettably, I did not get an answer, so I assume this editor is no longer active. I've been checking the internet to see if I could verify the occurence in Australia, but have not found it. I will thus remove Australia and Wales from the fossil range. Dwergenpaartje (talk) 13:26, 11 March 2012 (UTC)[reply]
