Location is in Missouri The area is dated to the Pennsylvanian Formation: ???? Hello! it is I once again I was curious on what this might be as it looks different from what I usually see in this type shale I have found Pyrite Calamites in shale but they usually don't have this texture so I was unsure of what exactly it may be. Zoomed in picture of the texture: Other side of this shale: Not Sure if these will help with the ID but here is the picture with the end pieces visible also for those interested here is the pyritized calamite I found near this:

This is said to be a coconut tree fossil. It’s from Liaoning, China. I don’t think Liaoning has coconut tree, rather does it look like a palm tree?

A friend asked me if this might be a fossil. I don’t know but I do know where to ask! The piece is heavy and will just barely take a scratch from a high-carbon steel pick. Thanks in advance!

I found this fossil??? on the Creek Trail at World’s End State Park in northern Pennsylvania. They are 3” and 2” in length. It doesn’t seem to fit with the other Devonian fossils I found. Were there plants at that time? Also does anyone know what type of rock this is? Have I been fooled and it’s just marks from chisels? There is also one very similar to this in the small museum in that area. I think it was a scout project and labeled “Unidentified”

Please advise what type of animal is this: it could be a trilobite, brachiopod or plant-animal. N.2 N.3 N.4 - this is most likely a small trilobite ( 1 cm) N.5 N.6 N.7 -left side segment N.8 - here I put some oil on this segment for better visibility

I am quite sure this is a tree/gymnosperm Is it a lepidodendron. It was found in the screameston coal member carboniferous, Northumberland England.

Hi. We found this amongst the mortality plates. It is an ordovician exposure along the water in Green Bay Wisconsin. Can anyone help us Id? There are two of these in this plate. I've never seen anything this delicate looking in any of the other specimens.

Hello wonderful fossil-people! If you and you're gang enjoy solving a groovy mystery, I have a post for you! This rock was found in an area of Northern Arizona that is very well know for producing lots and lots of bryozoan, brachiopod, and crinoid fossils, as well as crystals and geodes. The bit of rock in question was found in the side of what appears to be a broken geode. There is a triangular fragment of stone that does not match the material surrounding it. There is also a white discoloration encompassing the triangle that I've highlighted in green on one of the photos below. The colors in the 3rd photo are a little more true to what it looks like in real life. The geode is kind of a pink-ish color and the triangle "fossil" is a dark brown/reddish color. Given the abundance of marine fossils found in the same location, I wonder if this is also fossil. It just seems so out of place in this rock. I have oodles of bryozoan, brachiopod, & crinoids that I've found in the same location and I can share pictures of these, if it somehow helps So what do you think, fossil or random bit of stone? If it is a fossil give me your best guess as to what it might be... or even give me your worst guess. I'm not picky lol.

i usally find these in white on a gravel bar in louisiana , this was the first one i found in red and the biggest one i have , is it rare to find in diffrent colors ?

Found this in The Netherlands, Maasvlakte. Probably petrified wood, but not sure what kind?

I have this piece of chalcedony that I polished years ago in a tumbler. I always thought inclusions were automatically mineral or geologic but a recent thread said that is not always the case so I am wondering if any of these inclusions are biologic, thanks for your help. Oh and there is also an air bubble (last photo) not sure if that means anything

Hi, what is the identification of this fossil in my collection. It seems like a very good specimen.

Last weekend I took advantage of the warm weather to visit my favorite exposure of the Llewellyn Formation in Eastern Pennsylvania and collect some Late Pennsylvanian plants. I had not been to this site in some time but I was inspired to visit it again by some recent Llewellyn Formation fern finds by @frankh8147. I had the site to myself except for the noise of nearby ATVs and BMX bikes whose riders were also seeking to take advantage of the great weather. Despite temperatures in the fifties, there was still snow on the ground. I spent about 4 hours digging out and splitting large blocks of shale. What I like about this site is that you don't get the mash of dozens of plants on top of each other. Although the dark color shale makes it sometimes hard to see the plants, when you find a clearly visible example, the plant tends to be well preserved. As I am learning, this site seems to also have a wonderful diversity of Late Pennsylvanian flora. Overall the trip was a great success until the end of the day. As I was attempting to carry down my collecting bin with all of my finds, I tripped and crashed the bin into a large rock. While I survived the fall with only a couple scraps on my hand, the bin was totally destroyed and so too were most of my better finds. A view of the site Calamites appears to be the dominant flora at the site. Here is a large Calamites cistii trunk with my hand for scale Unfortunately the block was full of cracks and did not hold up, but I did find these cool smaller pith casts inside it I also found a really large block with several whorls of Asterophyllites equisetiformis. Unfortunately the piece was at the bottom of my bin and was totally obliterated during the fall. Here is all that I was able to save The first of several new finds for me were this partial and this immature Calamites cone (Calamostachys sp.)! Some of my favorite finds at this site are the remnants of lycophytes. I am yet to find an outer bark impression, but I have found several pieces showing the subepidermal surface. Here is an example of Sigillaria tessellata Cyperites bicarinatus Lycopodites meekii Lepidostrobophyllum lanceolatus Lepidodendron sp. Branches I thought this Sphenophyllum longifolium whorl was pretty cool due to its size and shape of the leaves Here are some of my better fern finds I was really excited to find my first ever Mariopteris decipiens with a partial Lepidodendron sp. branch on the piece too Cyathocarpus arborea This Cyathocarpus arborea would have been one of my best fern finds ever, but it too fell victim to my fall and did not survive. At least I have a photo! Laveineopteris rarinervis Neuropteris flexuosa I am still working on identifications for the rest. Last, but certainly not least, are a couple of mystery fossils. This plant appears to be vine-like with alternating leaves on either side. I have seen nothing like it in the literature . This plant is almost whisker-like, with thin radiating leaves that do not appear to connect to any central point I hope to make it back out to this site soon and hopefully continue finding new flora to add to the collection. Fingers crossed that I don't fall again!

Hi! I've been a great admirer of this forum for years. The counter-septarian structure thread... *chef's kiss* My brother-in-law sent me this picture and asked if I thought it might be a dinosaur fossil. I told him probably not, but that I knew just where to ask to find out what it is, or might be. All I have is this photo, but based on the circular kitchen-thing it's sitting on I'm guessing maybe around 8-10" in size. My uninformed guess is it's a plant stem if it's anything. I'd love to read your educated guesses. THANKS!!!

Hey everybody, this is a possible fossil I found in June of 2010. The matrix is roughly 6 1/2 CM long, and it was found in Arlington, Virginia in a small stream by an apartment building. If I could get any identification ideas on it I'd be really grateful, even if it isn't a fossil!

After searching through a couple of publications on Pennsylvanian plants, I am a bit stumped on what this plant could be. It is certainly not the classic fern or horsetail that one often collects from the Llewellyn Formation of Eastern Pennsylvania. The preservation is ok - not perfect, but better than some plant material I have collected from this site. I unfortunately broke the piece trying to transport it out of the site. Here is an attempted close-up of the individual leaves and their venation Here is the negative with some more preserved venation Any help is greatly appreciated. Thank you!

This past Saturday I collected some Late Pennsylvanian ferns and plants from an exposure of the Llewellyn Formation in Eastern Pennsylvania. I got lucky and found some new things to add to my collection, including the following. I am not quite sure what they are. My guess is that they are associated with a lycopod - possibly the terminal shoot of a lycopod branch where the Cyperites leaves come off. I did find Lepidodendron branches and Cyperites bicarinatus at this site. These fossils are really small - only about 1.5cm to 4cm in length. I also found this fossil that looks a little different than the other five- more cone-like, but I doubt it is a cone. It is also much longer than the other fossils, measuring about 7cm in length. The fossil continues underneath the rock chip- I tried to expose it more but the rock started to separate along the fossil so I stopped. Any help is greatly appreciated. Thank you!

A couple of finds from the Whitby area. Does this plant fossil have enough diagnostic features for an identification? Secondly, my daughter has been desperate to find some ichthyosaur material for ages now. She was so happy to find this, at first glance I thought it was just another piece of septarian nodule but on closer examination I think she’s probably right about it being bone, albeit likely an unidentifiable chunk. Still, she’s happy and it’s going in the ichthyosaur cabinet as her first find
