Looks like a leaf.......?


Becky Benfer

Recommended Posts

Found in a river near the north central part of Ohio. It looks like a full leaf to me. Can there actually be a fossilized leaf? I could google it I guess but I’d rather have your opinion and find out what it really is. Thanks for all information!

Yes.

Unfortunately this is not one of them.

There is a sight in northern Idaho where freshly exposed fossil leaves look as if they just fell from the tree.

Edit: I've never been there, but they claim the sight seen at the site is a dirt motorcycle racetrack.

I agree, not a fossil, unfortunately. 

Here is a geologic map of Ohio, to help identify what age the outcrops in the area found are.

It will tell you if that age had any plants that would have had broad leaves.   

I'm unfortunately not seeing anything on your rock that looks like a leaf. :unsure:

If it was found in the Ordovician, Devonian  or Silurian, then leaf is for all practical purposes eliminated. To the east of these areas plant fossils can be found.  If interested, check out this  paper:

@Becky Benfer Leaves similar to the types found on today's broadleaf shrubs and trees pretty much did not exist until the Cretaceous. Ohio's bedrock is older than that. You can't have fossils of what didn't exist yet. Ferns, conifers and gingko can possibly be found, but birch, maple, oak and such were still in the future. Younger bedrock is not found in Ohio possibly because it was high ground at the time and being eroded and the sediment carried to lower elevations, but I'm not sure that the jury is in on that yet. It may have been deposited and eroded, or simply just never deposited.

 

P.S. -- You're doing it right. If you don't know, ask. Those who ask get answers.

Liverworts were among the first to crawl from the sea like around Ordovician/Silurian and they are fairly broad for their size.

Yes, but they lack venation if I'm not mistaken and are more closely related to mosses and ferns than deciduous plants.

You see - I’m actually struggling with this one area because I found something there once that was plant related. So I keep going back to it hoping to find something else related to it.  I’ll post a pic of what I found prior to this. Can you help me with I should look for in relation to this? 
Thank you -

Only if telling you that I don't think it looks like a plant fossil helps.

Oh my.... you don’t think it is one? What does it look like to you? I was told mammoth tooth originally so I took it to a local arrowhead/fossil club. They decided it was a type of plant ( I can never remember the name. There were 2 types - one started with a “$” and the other I’ve forgotten. But they decided it was part of a stem of a plant. ) They said the plants at that time were MUCH larger than they are today.

My first guess would be mud stone. I really wouldn't have a guess what  plant fossil anyone thought it looked like.

I wrote it down and packed it away with the rock but I don’t think mudstone was their thought. Thanks however, I’ll be sure to compare it with other mudstone pictures.
