Hi I came across this while hunting for trilobites at a commercial Cambrian shale quarry in Utah near Delta and was wondering if it was a monoplacophoran or something else or just an odd rock formation. The shape is concave and about 2 inches in diameter. Any help would be much appreciated. Thank you!

Hello there! Since the kids are in day camps this week, and my husband was going to see a movie with his friend this afternoon, I took advantage of the available me-time and went for a little fossil hunt at Etobicoke Creek in Mississauga, Ontario (Georgian Bay Formation, Upper Ordovician). I have some ideas about what I've found, but I'd like your opinions, too: Specimen #1: trilobite resting place (Rusophycus, probably made by a Flexicalymene) Specimen #2: I think this is the monoplacophoran Cyrtolites ornatus - it was very flaky and some pieces fell

I'm having difficulty identifying this specimen. I found it in Osagean, probably Visean limestone in Lawrence County, Missouri, associated with various other monoplacophorans, which I believe to be kirengellids or something similar. The last picture is an example of an associated fossil of a similar size, being about 3.2cm from foot to apex. I also found in the same piece of stone a smaller, more rounded specimen, as well as fragments of a third. Stinchcomb and Angeli describe two species that share some characteristics with the fossil in question[1]. Kirengella oregonensis, which is foun
