Trilobits and something fishy?

[Darbi]

Hello! I have been lurking on this Forum for a while because I was very busy lately and still is!

 

I found few fossils and I thought it might be trilobits- pieces of trilobite and also something else that I thought it seems 'fishy' and somewhat resemble a fish spine. These fossils are not found in situ but the bedrocks are Silurian. If they are trilobites, it would be my first time found one!

 

I found this on the beach of Lake Erie, just east of Toledo, Ohio two weeks ago. Approximately half centimeter.

 

 

Yesterday, I found this fossil on the beach of Lake Michigan in Kenosha, Wisconsin - just north of Illinois state line.

 

It looks like a cross section of a trilobite to me. Approximately a centimeter and half wide.

 

Unknown and resembles a fish spine, approximately two centimeters long. 

 

Thank you in advance and I am looking forward to seeing the responses!

The first is a partial trilobite pygidium. The second is a thoracic segment of a trilobite. The "fish spine" is more likely a cross section of perhaps a brachiopod, hard to tell from the picture though.

Congratulations on your first “trilobits”!

Yay! My first trilobite I found! As for 'fish spine', I will have to get out my microscope for better pictures, but I'm currently on a work trip and then will be on vacation. It will be a little while before I get home for better pictures. Thank you for your response!

Thanks! Now I just need to find a complete one or at least mostly complete one.
