Shell ridges or animal scales ?

[Rocky Stoner]

Hi folks, another discovery in my garden.

I haven't seen this size or type of segmented surface before.

It doesn't really look like a shell as it has a wavy contour that I hope you can see in the pics.

 

Thanks,

Looks very 'leaf' like?

I agree, and had that in my descriptor initially but ruled it out having not found any plant matter yet at this locale.

Could be the first though.

I want to find a trilobite so bad, I think I'm seeing them in my sleep.

 

I'd like to include this mornings find to this post if its OK.

The next pic looks sort of like a crawdad tail with a longitudinal ridge.

Any ideas what it might be part of ? The one pic is a bit blurred, hope you can make it out.

Thank you much !

Hi, I found another example of the original feature in question.

This one might be a better representation. Just want to confirm ... plant, or ????

Thanks again.

... and a couple more, showing some nice bryozoans for kicks.

I'd say plant as well.

I'm not convinced these are even all the same thing. The first fossil could easily be the shell of a number of Ordovician nautiloids but not enough of it is there to say which. The last image could be broken pieces of bryozoans and before that maybe brachiopod pieces. I don't know any plants that look like that but maybe some of you who know the material from that area could be more specific about what plants you have in mind.

I do not see any plant material in these hash plates either.

I also would not expect to see plant in that type of rock. (marine shell hash,)
