Don't know what this is

[Fossils?]

Do you know what these are

[ynot]

Where are they from?

[Fossils?]

they are from grand ledge Michigan. found next to the river

[sixgill pete]

Some type of plant imprints maybe?

[ynot]

Agree with plant material.

Wait for some of those familiar with the area - They may know what plant it is.

[Fossils?]

thanks, does anybody have an idea of the name of the fossil?

Hi, it would be better not to put your fossils in a metal cup because there is a lot of reflection, prefer a mat thing to put them on.

Hi Tony, now, thanks to you, i have 500 points on my member's reputation.

[caldigger]

Thats OK, so long as he didn't ruin your reputation. Lol

[Darko]

Wow wow! They have a very big similiarity with my fossilized plants,almost the same ! 

I can tell you that could be a fossilized bulrush or equisetum sp.

I told u this cause it looks 100 ./. like mine miocene lake fossilized plant material. Very nice finds

Yes, they do look similar, but you also have to take into account that these fossils are probably from the Pennsylvanian, which makes for a difference of approximately 300 million years.

I know but it's still cool.

My guess would be loose cortex from something in the isoetalean clade.

I hope he won't.

The Grand Ledge location is known for some interesting dryland species such as Megalopteris although very rare. It is also known to have lots of Cordaites. I would assume that these are bits of Cordaites leaves.

 

I have several PDFs on Grand Ledge that I've been using for my research project that I can share.

[Stocksdale]

Like I said, I think what you have are Cordaites. But keep an eye out for Megalopteris which has been found at the location and are very rare and we don't know much about them.

 

Here's a couple plates from Arnold's "Preliminary Flora of Michigan Coal Basin" showing Megalopteris and other items from Grand Ledge.

The ones I have are more grass like. Have I IDed them wrong, or is the row like look (sgillaria) something I'm seeing wrong ?

[Rockwood]

I think I may be able to answer my own question now.

The finer veins in Cordaites leaves are punctuated by courser structures.

The fact that these seem to diverge slightly in the post is an indication of it being a leaf.

[Stocksdale]

It really is hard to tell for sure from the photo in this original post. It could also be wood fragments. I just thought with a Cordaites being common from the location that is is likely. 

 

Here's a photo of complete Cordaites leaf. This one is 72 cm long. They are large leaves with parallel veins that get gradually larger toward the end. Also a detail shot showing part of this one. They are usually found in small fragments. 

 

 

 

 

[Stocksdale]

Here's another one that is just a bit of a fragment.

I was a lucky one chosen to dig in Grand Ledge on a lottery once and we acquired quite a bit of fossils with plant material like this.
