mystery fossil

[Acuesquefossil]

Found this at hogs back falls in Ottawa lodged under a very big rock not buried , I’m thinking lodged there during the very high waters in spring that’s why it looks so clean, it looks like a crab sitting an a pc of wood imo. Any knowledge would be greatly appreciated and any further cleaning duties you could suggest please let me know

Hello, and welcome to the forum. I've never had any luck at Hog's Back Falls, but it's a lovely park.

 

I'm not seeing a fossil here, unfortunately, but a very weathered rock (possibly limestone). Just about all of Ottawa is Ordovician in age, so too old for crabs and wood. There are, however, some great spots for finding trilobites and graptolites, although those spots are diminishing, harder to access, or built over.

Thanks for the info dude.
