With the exception of one of these lovely specimens, they are all Cambrian-age (543-490 mya). This would represent the oldest fossils I own. And here's a link to his eBay - he has some lovely specimens up for sale, he is courteous and fast. Best of all, unlike so many sellers on auction sites, he knows his stuff so never a worry about being sold fakes (a very big problem on sites like eBay).
This will have to tide me over until the big quarry dig in a few weeks. On to the pictures!
