Hello everyone, thanks for letting me join the site! I'm an amateur fossil hunter from Toronto who has made a few expeditions in the past months. I've found a few fossils of interest that I'd like some help identifying. Below are links to photos of the fossils in question on my iNaturalist page, along with some additional details. Thanks all in advance!


The following were all found along the Don River in Toronto.

This was also found in Toronto, in a clean fill pile. A nice assortment of small invertebrates here.

This one is a real mystery. Also from Toronto, among clean fill. A bone fragment? A piece of vegetation? Coral?

These three were found today in Prince Edward County...

And finally, this Trilobite fragment was found in the vicinity of Arkona.

We prefer that you post the actual photos here.  Links can get broken over time or even link to malware so you probably won’t get much response until you do so.

Welcome to the Forum. :)


It's always better to post photos directly to the Forum. Links go bad, rendering the post useless. :shakehead:

Welcome. Ditto what the others said, pictures are better :)

1. Bryozoan



2. Strophomenid brachiopod(?) -- There is a similar orthid species as well. 



3. Possibly crinoid?



4. Bivalve (either Ambonychia or Byssonichia sp.)



5. Bivalve (cf. Colpomya sp.)



6. Hash plate containing bryozoans, crinoid ossicles, and high-spired gastropod (Lophospira sp.)



7. Possibly trilobite fragment (Isotelus sp.)



8. Possibly Maclurites sp.



9. Nautiloid (taxon eludes me at the moment).



10. Gastropod (possibly Hormotoma sp.)

Thanks everyone for the responses! I will be sure to figure out a way to include the photos in the post directly next time.

I concur with Kane's assessment.
