I cannot stress enough that this is an active quarry with regular blasting and areas that are not entirely safe, so there is no messing around here. Full safety equipment (steel-toed boots, hard-hats, and reflective vests are absolutely mandatory), and it requires signing a legal waiver before entering the site. On the right is the entrance.
I still have a bucket of stuff to go through, and some IDs to put on the finds. In all, it was a fantastic and exciting trip. My thanks to Malcolm for being our gracious and knowledgeable host.
The site boasts a heck of a lot of variety for trilobites alone. Below is a table of identified and described species found in the Verulam Formation by B.A. Liberty (1969) Paleozoic Geology of the Lake Simcoe Area, Ontario. Geological Survey of Canada, Memoirs 355. Since then, Ludvigsen (1979) describes a few others, including Amphilichas (a pygidium of which Malcolm found just this weekend, and is considered a rarity - and never found whole).
