New Finds From Mount Carmel And St. Clair


Shamalama

Recommended Posts

I took advantage of the good weather on Saturday (although perhaps I should have waited until Sunday when the weather was in the 70's) and drove up towards Mount Carmel and Shamokin Pennsylvania to look at some of the coal mine dumps in their area. These rocks are north and west of St. Clair and have a different color and preservation.

My first stop was at a dump next to the road I was taking to get to Mt. Carmel near a small village called Gilberton north of St. Clair. The dump here has a lot of Sandstone and Conglomerate as well as some Shale. I was finding some fossils but not too much until I found my first recognizable bark fossils.

An odd looking texture, not sure what this is

Not finding too much else I headed towards Mount Carmel passing through Ashland (home of the Pinoeer Tunnel, an attraction that lets you ride in carts into an old underground coal mine) and Centralia (famous for the coal seam fire that exists under the town that started in 1962 and still persists to today). At this site I found more plant fossils as well as a few bark impressions.

Some nice large Neuropteris (possibly gigantea?)

My first Lepidodendron bark.. I'll have to compare it to the vast collection Bruno has posted to determine species.

One other interesting find was this branch with "thorns" along the side. I think I read somewhere this is a climbing branch or vine for some species. It could also just be a denuded branch for some other species.

I had some time left in the day and decided to hit a different mine dump near St. Clair on the way home. This is in an area that is currently being reclaimed so it's best to hit it on the weekends when they aren't working. The rocks are not the typical deep black with white ferns and the flora is slightly different too. Probably from a different layer in the Llwellyn formation.

Could this be a cone?

Neuropteris branch

Some kind of decorticated branch, not sure what all the pits are from, rotting or maybe animal feeding?

This is what a reclaimed area looks like, they regrade and add some topsoil and then plant with grasses.

A Panorama of St. Clair (looking south) from the top of the mine dumps. The shopping center at the bottom of the picture used to be mine dumps but they were removed as part of the reclamation process. There are still some dumps behind it but they will be gone soon. You can see a reclaimed area in the upper left section of the photo.

Very cool fossils. I have seen those hills and had no idea that they were tailings from coal mines. A friend told me what they were when I was up there visiting. B)B)B):)

It's my bone!!!

Wow!! Great finds. The pine cone and neuropteris are sweet. Good luck on your next hunt.

Really neat stuff Shamalama. It's amazing how many different things you can find in one of those piles!

If you believe everything you read, perhaps it's time for you to stop reading...

Thanks for the comments, guys!

Bruno, You mean to say that all those little lines on the leaf were hairs of some sort? :o Too cool! :jig:

Here are a couple of high resolution closeups of the leaves:

Yes Dave ,these lines are hairs typically ,there is also little leaf side at the base of large pinnae....look this draw by professor Laveine

In northern France , Macroneuropteris is a very rare plant in 20 years of collecting I have found only 3 specimens ....by cons in the St Clair aeras in U.S, she seems very abundant ....various collections of Dave seem to prove !

Does Steve from U.K and Romans from Ukraine have found this species ?

Hi Dave, I'm really glad to see your hunting success, congratulations! I know well that finding on the tips is really hard job.

Very good Neuropteris leaves preservation. Unfortunately I never found such kind of neuropteris here and very interesting to see it. As for your 'odd looking texture' I would IDed it as a fern stem (??) or very decorticated lep bark.

Hi Bruno, unfortunately I didn't. Very impressive Dave's finds, well done! Roman

Dave..... Nice fossils looking good, and thanks for the location pics, they are always nice to see.....I could be quite happy wandering round your spoil heaps.... although rain sometimes helps me spot stuff ....I may miss that...lol

Bruno.....I have something the right 'shape', but looking at the reconstruction, the veination looks different, what do you think?

Hi Steve

the veination looks very different ,there is no hair ,the edge is slightly wavy,the shape is very variable ,it is an heteromorphic leaf

I think to a terminal leaf Neuropteris heterophylla
