I've remember the BC Rockies and have pinned several pictures to my Geology board at:

Such as:

And Ammonites:

And quite a few others.

Though, I don't know if you can see them without being a member of Pinterest??

From what I remember of the Nanaimo Group sediment from which the coal was mined it is a complex of deltaic sediments and turbidity flows that was deposited primarily in the Cretaceous, but also into the Paleocene. The source was to the west - a geo-anticlinal terrain which buckled up over the subduction zone. So much the lower section of sediments at Nanaimo are of the right age for ammonites. You just have to find the more marine sediments in the Group. A blogger I follow wrote about it a couple of years ago:

And he has other posts that cover Vancouver Island that you might find interesting.

That post about Nanaimo was pretty good-the First Nations people of this area still create petroglyphs but use a Dremel now, there are a few at the salmon hatchery we visit regularly. The fossils of this area are interesting, I thought we should have a fairly good selection given the coal mining that helped create so much of this particular area!

I'll have to try those Pintrest when I am on my PC, for some reads my iPad doesn't even want to copy them to open. Weird! I think we've seen a few fern and very simple fossils but nothing like we have seen when we walk along creek beds in either the BC Rockies or over in Alberta in the Crowsnest area. Nothing huge, mind you but enough to to get the kids excited!!
