Cretaceous trace fossil found in Niagara Falls, Ontario

[Paul Nobes]

Hello everyone, my first post here. Am I correct in calling this a cretaceous trace fossil? Found by me probably 50yrs ago, in a local sandpit, I think, or on Lake Ontario shoreline. Looks to me like images of cobbles from Faringdon, England.

(I've got an odd assortment of interesting rocks, artifacts and fossils from my childhood explorations, but only now trying to learn more about them. ) All help very much appreciated! Hope to learn a lot here. Thank you.

Trace fossil would be my guess, but I don't think there is any rock of Cretaceous age (145-66 million years) in Ontario. The rock there is all much older (generally Devonian and earlier >360 million or so). The Ontario experts will fill you in on more detail.
