More Pennsylvanian age flora

Recommended Posts

This is Pennsylvanian age Mazon Creek type material found in Indiana.I have a lot of raw material that has been left outside soaking in water to freeze this winter.I've recently sorted through a lot of this material after Indiana's first extended freezing temperatures.These are some of the pieces that have questionable ID’s.

 

1.Segment of cone bract?

2.Seed or base of a Cyperites leaf or some form of bract?

3.I’ve been finding these small pieces of plant material with finger like projections.Not sure if these are just shredded plant material or something else?

4.Seed?Not sure if there are any distinguishing features that would warrant an ID other than Carpolithus sp.

5.Fern leaf curled up? But what are the spots?

I wish I had time to share some of the more common finds from this round of splits.Some of the rocks that I find split in multiple planes.Here’s an example of a rock that has a Cyclopteris,a Pecopteris and a Macroneuroptis.The Pecopteris and the Macroneuroptis are at right angles to each other.Sorry about the poor photo quality.

I found something similar to #3, the fingerlike projections from my Mazon Creek nodule stash.  I posted a few weeks ago and it was ID'd by RCFossils as 

 

"I think the plant is immature foliage. I would call it Asterophyllites."

 

I think it looks similar to yours.

 

Here's my specimen:

Thanks.You jarred my memory.I have a photo in my collection that is similiar to yours that I labeled as Lepidostrobus.Lepidostrobus.JPG

Here's another cone segment that I've labeled as strobilus.

sphenopsid cone 3 or strobilus.JPG

If this strobilus segment were folded in half then it might look like the photos in #3

Everything seems right.

 

No. 3 looks like plant material to me (I'm not good with Pennsylvanian plants, I really only know Mississippian ones), maybe Annularia?

 

Lepidostrobus looks good on that specimen.

Nice finds, No. 2 looks like it could be a Lepidostrobophyllum sp. and No. 3 looks a Sphenophyllum sp. such as S. cuneifolium.

Regards

Thanks for your replies.I feel confident tagging a couple of these photos with ID's now.
