New to fossil hunting, no idea what these are!

Hi everyone! I am brand new to fossil hunting and have two new fossils that I found today. I know pretty much nothing about them and I’m hoping someone can tell me what they are! They were found on the beach at Lighthouse Park in Port Huron, at Lake Huron/the mouth of the St. Clair River. I’m a little more interested in Fossil #1 (I labeled them in the photos), so there are a few extra photos of that one. Any info at all would be greatly appreciated, I am dying of curiosity!

Not sure about item #1 

Item #2 is a water worn Horn coral. It shows the internal structure.

I agree with Darktooth. I'm not so sure if #1 is a fossil at all. Maybe an extremely worn brachiopod.

Very cool! Thanks so much, guys!
