Hello folks,
I took my first long walk on the shore of Lake Ontario 2 days ago, generally looking for rocks to tumble, and I also found this. Usually the fossils along this area are jumbled up "death plates" of many little shell pieces in basic gray basalt (I think). this one stood out for size and detail, plus the cavities inside the shell never filled with the base rock, so they have some druzy in them:

I'm a complete novice when it comes to fossils, so if anyone can identify what this is, I'd appreciate it!

Thanks,
Andy III

With the sharp, well-defined edges and chambers, I thought I was looking at something like a cross-section of a snail shell. Thanks, Andy III

Looks like a fragment of some kind of Cephalopod, like a nautilus or ammonite.

rocknrob: That was one heck of a windstorm that thankfully missed me. I guess Seatac almost hit 60mph gusts. I bet those were some fun landings Nov 20, 2024 21:55:16 GMT -5
