I would but none around here. Closest place I can work with is in Pittsburgh PA. Carnegie natural history museum is there. I have been in touch with the paleontologist from there. If someone near where I live in elk county that I'm not aware of wants to have a sit down is more than welcome to meet with me. I have met with fellow members on here in the past. It was a fun day digging in bennezette that day digging devonian period plants. Plus anyone that does meet with me can dig material with me of carboniferous period. Other area is off limits as in a secret spot for my friend and kids only. My friend is not doing well and only 1-3 months to live based on Drs.

+1 for crinoids! Pretty neat preservation, I've not seen them like that before. The disk shapes are often mistaken for vertebrae because of their discoid shape: They are a sort of spinal column, but not a vertebrate! They belong to the class Crinoidea, a group of marine echinoderms, related to starfish and sea urchins. Lots of people think they're plants, but they're not, just a wiggly waggly prehistoric creature that still exist! The discoid shapes are a part of the stem called a "columnal", which are small tileable shapes that allows them to move around and bend freely.

2nd picture looks to have some interesting textures and the darker band almost looks like carbonaceous plant material. Do you have any sharp clear images of that layer/area? Last 2 photos show you are on to some plant material--nice! Looks like a great place to hunt. You need to put a scale in photos or provide dimensions to help us figure sizes. Bedding/weathered areas look a little loose/sketchy with possible sluff off/rock fall--be safe! Regards, Chris Should have added that the 1st photo doesnt strike me as Calamites but rather a sedimentary/weathering feature. Closeups of the rocks/layering with a scale may suggest otherwise. Those plants did get pretty big...10m common up to 30meters tall... Here's a relatively small 20 cm long section of a find from Whitley County.

Sometimes plant roots will grow into small cracks or crevices in rocks because they tend to retain water and when the plant dies and the rock is exposed to the weather the dead roots fray and resemble hair. If you've ever dug a hole in the ground near bushes or other plants you have probably seen rocks with roots grown into them.

Sorry, should have been more specific. Isn't this the place "Across from Pit 4"? I guess I still think of it as Pit 4. I have never collected Pit 4, but if what you have is predictive... it would be similar to the "Across from Pit 4" locality. Pit 2 and 3 is terrestrial - mostly plants and a rare animal. Cheers, Rich

Can anyone tell me if these are actual fossils or just geological formations, although they look like fossilize plants to me, it would be very surprising to find fossilized plants from the late Ordovician period. both rocks were found in the Nicolet River Formation on the banks of the Richelieu river

None of the leaf tips are clearly visible and I also was undecided among three species of Annularia, therefore the question mark as well as the question marks on the other plants also. All of these specimens are from 1 to 2 centimeters, including the unknown which has at least 1/2 centimeter in thickness as well. I was hoping you or one of the other MC collectors would say "Oh yeah, that's definitely a . . . .", but I guess that's not about to happen. Thanks for taking a look.

The plants look pretty good, although it's hard to see the first Mariopteris. I like them because the pinnules look more ornate than others. Cheers, Rich

I’m thinking this is Stigmaria. Scale bar = 1 cm. Found in the shale below the Brush Creek limestone, a zone with many plants.

Unsure on specific IDs for plants, bad at these. As to your last unknown, I don't see any defining features. I am thinking it is an Essexella.

Ah, ok, didnt realize you talked about fossil plants.

jpc replied to Fletcher's topic in Questions & Answers
Geosciences is one way to go, but biology is just as good. You will certainly need to get some background classes in either or both as part of your plan. It may be a long but rewarding trip. i would actually talk to a few professors whose work you find intetesting be it dinosaurs or brachiopods or plants. They would be able to tell you what you would need to persue your dream. -
Show Us Your Fossils Challenge Mode: Ordered By Geologic Time Period!
siteseer replied to MeargleSchmeargl's topic in General Fossil Discussion
Yes, I didn't think of the Permian as a stumbling block but it can be. You can find Early Permian terrestrial vertebrates from the southwest U.S. and Germany and some plants that age here and there. It's tough to get Late Permian material. Some ammonites have come out of Russia and Timor. -
Thanks yeah I keep all oddities. Sometimes get lucky that it's more than an oddity. I collect mostly plants for 90% of area around here is Carboniferous. Some areas devonian and some in 10,000 yr range hence petrified wood for it takes 10,000 yrs to petrify. But going gold panning in areas of drift material has me stumped on materials for it's not something I usually come across. Sadly I couldn't put an age on that stuff for glacial deposit hit area twice 10,000 and 70,000 yrs ago. New ball game but will get the hang of it. Just got to listen and learn for I can be very stubborn when I'm sick for my head isn't clear. Thanks.

Hi Petrified, you found a stone that stuck out from the ones around it, you took a close look at it and described what you saw, you learned something. Just that it is no fossil egg (which are exceedingly rare) does not mean its junk. Ironstone concretions are not rare, and they are among the most common pseudofossils to get asked about on the forum. But they are often interestingly shaped and nicely coloured. I have collected many just because I liked their look. Plants are great, but dont turn your back on the stones just because the ones you found yet are not museum stuff. They may look good in a garden or flowerpot, like mine do. Best Regards, J

It was the stuff sticking out of end that caught me off guard. Otherwise would of tossed it right away. But after all the replys and information all three are labeled as junk lol. I need to go back to plants everything else is a headache and a half. Learning but slowly in that area but will get there just need to be more interested in it. If interested I learn real quick but not as interested as I should be at the moment. Just a phase. Oh well thanks everyone.

Hi everyone, I am pretty new to fossil hunting, and have just started going for plants. Recently, I visited a site in Ambrige, PA, and found abundant plates containing neuropteris and calamites. I split some leftover shale when I got home and found what looked like dried leaf veins tightly sandwiched between the shale. There are several of these structures that consist of a central vein with smaller veins that branch off. These are not fossilized, and are not a part of the rock, as they can be easily brushed off. I just find it hard to believe that an entire modern leaf could get wedged in there. Are these fossils in the making? Has anyone else encountered this? Thanks in advance!

What factors or interests, influenced the primary focus of your fossil collecting?
Fossildude19 replied to Rock Hound's topic in Member Collections
Always interested in prehistoric things. Found out what was available near me. Started researching and looking hard. Was lucky, and found a few places nearby. Specialized in the local Early Jurassic areas nearby, and collected what I could. (Fishes and plants.) But interest in other fossils grew and have now expanded my collection from what was available locally, to making trips out and about, to find what I like to find. Trilobites, phyllocarids, gastropods and other invertebrates.- 17 replies

Both great points! Virtually all of the hollow enamel-only fossil shark teeth that I have in my collection are teeth that were forming when the shark died. As Coco mentioned shark teeth form "inside out" with the enameled surface being created before the dentine is added inside and completed with a root. Given the number of teeth that a mature shark may have lost in its lifetime--I've seen numbers like 20,000-30,000 (or more) bandied about--finding teeth that were forming in the jaws when the shark died account for a very tiny percentage of the total. Though they are not as impressive as a "complete" tooth, I think they are extra special as you have a little more information available in teeth like these. So there is no possible confusion, the "root marks" as Al Dente mentioned are plant roots (not tooth roots). The scrawled markings on the enamel are where plant roots were in contact with the tooth after it had left the shark's jaw. This is an extra bit of taphonomic information indicating that at one time this tooth was likely buried high and dry where plants could reach their roots down to the tooth and leach some minerals out of the enamel. Actually, it is the symbiotic mycorrhizae that work with the plants to extract minerals from the environment. https://en.wikipedia.org/wiki/Mycorrhiza The tooth is not very tall as you can see the discolored edge where the enamel was stopping and the root would likely have attached so this seems to indicate this might have been a more posterior tooth. Lots to tell from a simple tooth. Cheers. -Ken

You are right; the Cameleolopha bellaplicata oysters occur in the Arcadia Park Formation of the Eagle Ford Group. The upper part of the Arcadia Park Formation from Dallas north to Sherman contain flaggy sandstone layers that often contain oysters, shells and shark teeth. I suspect that the largest sandstone layers are related to the Bells Sandstone Member of the Arcadia Park Formation east of Sherman. The lowest part of the Austin Group is not very productive near Sherman although I did find a fish jaw with teeth in west Plano in what sort of looked like the Atco Formation that is better developed south of Dallas. I don’t remember seeing a single outcrop near Sherman where you could clearly see the Eagle Ford/Austin Group contact. The contact is covered with slope wash and plants. Just south of Center Street in Sherman, the Austin Group is at the top of the bank of Post Oak Creek. The creek bed is in the Arcadia Park Formation. Hike south in Post Oak Creek from Center Street and you will see lots of sandstone with teeth and shells in it; this is probably the source of the teeth in Post Oak Creek further south. In the oyster beds note the colonial corals and the ramose bryozoans that grow on the oysters. South of Sherman and below the Austin Group rocks in McKinney, Frisco, Prosper and Plano you can find multiple flaggy layers with teeth and shells, but very few oysters. A few miles west of Sherman along Choctaw Creek there is a large ledge of Cameleolopha bellaplicata oysters, but the shark teeth in the flaggy layers are nearly absent. I did find a layer of some freestanding lacy bryozoans a few feet below the oyster layer.

This is from my own collection. I like it very much and it is like a peaceful painting to me (a fish swimming in the beautiful water) I know the “plants” are not plants, they are dendrites of manganese. But yesterday I was told that the fish is not a fish either, it might be an impression of some kind of insect Want to know what your guys think. Thank you in advance. (it is from Liaoning, China)

Nice ones! Clean the plants a little. This one may be a rarer one like Mariopteris. Cheers, Rich

Tidgy's Dad replied to bockryan's topic in Fossil Hunting Trips
Yes, it looks like a crinoid holdfast to me, though I'm interested to know what it was holding onto? Love the plants.
