Went looking for ferns and plants today. Spent my lunch hour splitting shale nearby. This one caught my eye. The ghosted pattern around the stem is interesting. I feel like it’s part of it seeing how symmetrical it is. And ideas? Length of the stem part is 2 1/8” (Don’t have a metric ruler handy) To me, the bottom portion is the base, so the shape is confusing.

Location is in Missouri The area is dated to the Pennsylvanian Formation: Muncie Creek Shale I was cracking Open some Concretions I found and this Came out of one! Unfortunately not in One piece. I was fortunate to find almost all of the pieces, including the tip, but do not know what adhesive to use Never the less I would like to know what species this is from! I have found various prehistoric fish parts from the rock Pile this has come from, Such as teeth from Eugeneodontida and Cartilage. The tip

All, I found this fossil in a shale deposit of Pennsylvanian age in Northeastern Oklahoma. The shale is probably Chanute formation and contains other marine fossils. I would appreciate any help with ID. Best wishes.

Hi all, I discovered this rather unusual fossil at an exposure of shale a few feet above the Mahoning coal of the Glenshaw formation, which is Westphalian D in age. I was thinking that it is probably just Lepidostrobophyllum, as the Mahoning coal is pre Carboniferous Rainforest Collapse so lycopod material is relative common within its horizon. For those of you that don’t know, Lepidostrobophyllum is a leaf like part of the Lycopod reproductive cone. However, I have found arthropod material at this exposure before and just wanted to make sure that it is in fact Lepidostrobophyllum and not something else. Thanks in advance

Folks, I found this fossil mollusk from a shale deposit in Northeastern Oklahoma. The shale is of Pennsylvanian age (probably Chanute formation), and contains other marine fossils. I would appreciate any help with ID. Best wishes.

I have finally made the step to find my own fossil beds instead of relying on pay-to-dig type locations. My research has led me to a local formation which will be practically spilling out with permian specimens if I can find it. My problem is finding the very thin fossiliferous layer. I havent had a geology course since high school and I dont recall a whole lot of it. Frankly, I'm having trouble identifying rock types. siltstone, mudcrack, dolomitic mudstone, sandstone, paleosol, shales.... my head is spinning. I understand the grain size differences from sandstone to shale, but what I find in the field is confusing. I find the same appearing rocks with differing characteristics. In one location its a very hard sandstone with no apparent cleavage. In others its a wet, soft sandy-stone that will partially separate along planes. In another it cleave along clean planes but is extremely fragile and disintegrates into pebble size bits. None of these matches the fossil bed description except for the coloration. I understand these are likely different levels of the formation (and completely different "rocks"), but I cant really define what I'm holding. I havent found any fossils in any of the rocks I've search yet in road cuts. I have found some property locations with more possible exposures, I need to get permission to search them.

Hello, I came across this while collecting some rocks to test. I did not take it for a fossil at first, but I am at a loss concerning what could have formed the pattern of the rock. The raised lines which I can only describe as “veiny” are really well defined and contoured. The dimensions are 4cm x 1.75cm x .75cm. I believe the rock is shale and it was found in Northern Mahoning County near Youngstown, Ohio alongside a river. The geologic map suggest that the rocks in the area may be from the Pennsylvanian period. Any help you guys can offer would be appreciated.

Hi all, I didn't see anything about number of photos in each post so I have a few different IDs I am asking for help with, I've read the guidelines and will try to ensure I cover everythnig. These fossils are from North Cowichan on Vancouver Island, BC, Canada. I believe this is the Maple Bay Formation in the Nanaimo Group and is from the Cretaceous period. The rock was very friable/fractured and may fossils were not collectible but I did collect a few and get pics of some in the field. 1. Bactulite? 2. Bryozoan? 3. Ammonite? (8 x 5.5 cm) - I can't quite get a good picture of it but there is an impression of what looks like a ribbed coil ~ 3 cm wide like a segment of ammonite) 4. Brachiopod? (sorry, forgot the ruler in that one but it is ~ 2 cm in diameter) Thanks for any assistance

Went up to Douglas Pass, Colorado today for a hike with my wife. I have always hunted for fossils at the Radar Dome location. Today we decided to scout around for another location to collect. Hiked up a very steep hill to a shale exposure and found this larvae after only 1 minute of looking. We had not come prepared today to collect anything. Will probably head back up next weekend. The larvae is approx 2.25 cm across. There are also some parts of other larvae on the piece.

First off, sorry for taking a “field photo”. I took a photo of this and then we left it back at the pit (it’s pure chaos trying to keep 3 kids in order lol). We found a good bit of these darker things near the top of a shale pit in Mifflin Co (I think we’re still in Mifflin, if not it’s the southern tip of Centre). That one on the left by itself is around 2 1/2 inches long (~63mm). I tried to do some research and I think there was also some burrows in the shale in that area, but I’m a total noob so maybe I’m just seeing what I want to see (I’ll get photos of them next time we go out). Hopefully that’s enough info to get started. Let me know if I can add anything else or get more photos when we go back!

Listracanthus denticle?, then another or different altogether?
Bonehunter posted a topic in Fossil ID
Hi all! Well, now I am into splitting shale finding conodonts and will post my best ones soon, but I've come across several of these which are comparable to images in the forum and on references to Listracanthus denticles?. It was found in Pennsylvanian Stark shale member in Kansas City two days ago. Is that a fair i.d.? They're are all very similar, but I've found this as well- a "carbonized" film with a structure that doesn't have straight lines, but somewhat veinated? Very difficult to get pics of that so provided several in different light. The first is 27mm long and the black piece is only about 2-3mm at most. Am I on the right track on the first, and any ideas on the second? same, fish fin, plant impression/other? thanks! Bone Then here's the other one- found in a different slab of shale but same level- the bottom "ridge" appears to diverge in the first couple pictures, then there appears to be divergence in the middle in the darker pics. Any thoughts welcomed! Bone

Hi, just wondering what you guys use to extract fossils from shale thanks.

Folks, These photos are from a small section of shale I picked up in Northeastern Oklahoma. The shale contains marine fossils of Pennsylvanian age. I have questions about a couple of the labeled objects. I’m thinking the center one may be a brachiopod (or possibly a bryzoan--it's hard to tell because of the crinoid plate resting above it). The one on the right looks to me like a bryzoan. However, I’m a novice at identification so I’d appreciate any opinions. The putative bryzoan appears to have grown on the crinoid stem. Best wishes.

A while back, @Darktooth and I did a little trading. Somewhere in the mix, he mentioned that his educational outreach (and collection) would benefit from some examples of C. chubutensis. I sent a couple of examples and it seems all that cuspy goodness went to his head. I received a COVID care package from Dave a week or so ago that contained a complete New York fossil trip in a box! I was completely blown away and the objects have given me quite a bit of entertainment. The field-trip-in-a-box was complete with lovely hand written tags, so everything was ready to put right into a large riker box. No way Dave could have known this, but my family has been self-quarantined because my son had a known COVID exposure. This care package has been a welcome distraction, to say the least! My absolute favorite is the Grammysioidea. I'd seen these in past posts and online. They are just as cool in person as in pictures. Thanks for the awesome collection and distraction Dave!

Nodule with embedded object (is it a fossil or mineral accretion?)
Gramps posted a topic in Fossil ID
All, I wonder if someone may have an opinion about the object(s) in the small nodule shown here? The entire nodule is about 0.63 inch wide x 0.75 inch long x 0.5 inch thick (1.6 cm x 1.9 cm x 1.3 cm). It came from an area of shale that is likely of Pennsylvanian age in Northeastern Oklahoma. The shale from this location has many fossil marine invertebrates. I'm assuming its a mineral formation, but any thoughts would be appreciated. It is very hard to get the 3-D relief to show up in photos, so several angles and lighting conditions are shown. Best wishes.

So- been starting to look for my first conodonts in black shale in the Kansas City area and I commonly see what appears to be mineral deposits left when water seeps through layers, then dries, but these are in winterset limestone (as best I can tell) and while they look similar, maybe these are trace fossils? thanks for taking a look!

Marine burrow. Found this down in the Mancos shale, loose. Possibly from the overlying Mesaverde formation. I have seen many burrows in the Mesaverde sandstone. -
