I wish I could say that I found this one but was able to talk a friend of mine into parting with it. This is an almost complete pygidium of the elusive giant lichid Terataspis. It was found in a remote area of Northern Ontario. The pygidium measures approximately 10 centimeters across.

Haven't posted any trips in a while, although I've been on quite a few in the last while. This trip occurred this morning, about 15 minutes' walk from my backyard. It started with low expectations and ended in high reward. There was an area I've been returning to for the last six years that I've pretty much tapped out. During that span, it has been generous to me, although it is now transitioning into forest. I decided to take a resigned poke at an area next door to it where a new housing development has been in progress for the last year, and like a lot of these new tracts there is a permanent adjoining drainage area that are sometimes spruced up into walking trails and ponds. It was in this area that they also trucked in a substantive amount of limestone, which I'll reasonably assume is Dundee Formation as that would be the cheapest to acquire. Or, it may be Lucas Fm from nearby Ingersoll. Poking around the brutally hard grey limestone riddled with corals, I figured it would be more of the same old, same old of the Dundee. I'm not a coral person, but I did find these ones neat. Some of these were bigger than basketballs. There were at least seven distinct types of coral I encountered. Here's a tiny sample of the ones I snapped pictures of:
