ID help. Henderson Harbor NY Lake Ontario

[Drufeus]

I found these today in Henderson Harbor NY along the shore. One looks like a plant of some kind and the other a cephalopods of some kind? No clue as I've never found something like this and can't find anything similar online for the plant like one. Any help would be amazing and thank you!

Bryozoans?

And the nautiloid Spyroceras.

Welcome to the Forum!
The first one might be a bryozoan (as Adam suggested), the second one is clearly an orthoconic cephalopod.

[Drufeus]

Thanks to both of you!! I have more section to the Othoconic Cephalopod but not as exposed and am afraid to chisel around damage it. Bryozoan makes sense after now researching it more. Thanks again and believe I am hooked!! Plus my 2 year old loves throwing rocks so will be fun to have him out and about.

Makes more sense than spiroceras. The other radiates out from a point but it's hard to see.

 

@Drufeus. Do you know the geologic age of Henderson Harbor rocks?

Not Spiroceras! 

Spyroceras.

Like this one from @Jeffrey Pin the members gallery.

Devonian, Lebanon, New York.

Not too sure but the research I have just read is around the Devonian Period and some Late Cambrian. I'm completely new to this with 0 knowledge about it. Hope this helps.

I tried to figure out looking at geologic maps but it's a difficult area to pinpoint and the maps are complicated to the point where I gave up. What county is it in?

I'm trying to deal with this page:

@Tidgy's Dad. I didn't see the sections when I first viewed the cephalopod so may very well be spyroceras.

Jefferson County and thanks for the continued help. And I was on that page too. Mind hurt so much I poured a bourbon.

From what I can gather the area is Ordovician. I really like your cephalopod!

[Fossildude19]

Looks like that area is mostly Ordovician in age. 
That would make the cephalopod more likely to be Michelinoceras sp. . 

Spyroceras was a Devonian genus.   

 

EDIT: Welcome to the Forum.  

Nice finds - thanks for posting them. 

 

[Drufeus]

So I decided to gently tap away at the other section.
