Location: Missouri Age: Pennsylvanian Stratigraphy: Iola formation Hello! Here is an odd find from the other day on this Paraconularia sp. fragment (lower half). I am not sure what organism left it but I was wondering if anyone on here recognized it as anything. I was thinking possible gastropod but I know other boring organisms existed back then. There is a small odd indent near the base of the boring that perplexes me, making it hard for me to visualize where the organism would have been/moved while feasting.

I keep finding these strange black marks. At first I thought it was a break line between two plates, but now I'm not so sure. They are always exactly 5 mm wide and 1 mm thick and they usually have a thin, lighter line in the middle. Is this a trace fossil of some kind? worm ? alga? Period: Ordovician Formation: Nicolet River formation Location: Quebec Here are two examples, A and B: A – In the first and second pictures, you can clearly see the dark line it is partly hidden in the rock, and the thickness is evident in the second picture. B – In this plate, the dark line is not flat and seems to go over some brachiopods.

what causes this pattern in sandstone im familiar with the classic vertical scolithus sandstone but they are usually all over the rock in this case its only a tiny area in an otherwise plain rock and they are very tightly packed the total size of the rock is ~20x15x10 cm

Hello, I wanted to share a find from my last trip into the Alberta badlands near Drumheller. I believe it to be an Albertosaurus print(s?), and the local museum will send a technician to confirm. I haven't found any records of tracks found in this area, at least that still seem to be in layer. The shelf I found this on painted quite a picture. About 2 meters away were a grouping of crustacean(I think) burrow ichnofossils. This makes me believe the area was likely an intertidal zone and I pictured the albertosaurus walking through the area at low tide. Sometimes it's fun to picture the scene as it could have been.

What am I looking at? Fossil? Old bones? Animal? Plant? Sea creature?
Kalei posted a topic in Fossil ID
Hello! I inherited someone’s rock collection and this sandstone rock was in it. It has a cast of what looks to be some type of tunnel system and then it has a small fan like animal/plant “trace” about 4cm. I thought at first it was a fossil, but after looking at it under some microscopes I’m not positive now. I don’t actually know what a fossil this small looks like under a microscope (20x-100x). I unfortunately have no idea where this rock came from so I don’t expect an exact species, but if someone could tell me if it is a fossil or just old bones and what category it could be (plant, animal, bug, sea creature, etc.) that would be helpful! As far as I can tell there are three “branches” and a “fan” matrix on both sides, however the right side is mostly eroded away. The left side is mostly intact and it looks to have a spot with something on it. I thought this was just a piece of rock still stuck to it, but after looking under the microscope it’s definitely made of the same material as the rest of the structure. However, the spot looks like it’s darker in color. It also has an interesting “stem” or “head” area that after looking at it for so long has started to look like a pirate’s skull lol so I’ve dubbed it the “pirate’s head”. Anyways, I focused on the branches, left fan, and pirate’s head in the close ups and tried to get the best contrast possible. I also included some very up close looks any the pirate’s head so you can better tell what the mineral structure looks like. Sorry about all the photos, I figured as much documentation of it would be in determining at least what type of life form this was. Thank you in advance for whatever help you can give me! -Kalei cast tunnel? Fossil/old bones? Fan structure branches Pirate’s head/stem

Okay so I found this specimen at the Taughannock Falls in Ithaca New York. I found it at the edge of the gorge which consists of shale, composed of slit and clay that fell onto lime mud and hardened into rock. I've done some research and it appears to be a Brittle star trace fossil formed by their arm grazing the sand floor. Although, these Brittle Star fish traces are known as "Pteridichnites biseriatus" and they have only been discovered so far in upper Devonian shales out in western and eastern Virginia. I'm not an expert but to my knowledge the Ithaca geological formation is Devonian and was slowly covered by sand. Is it possible that the Brittle Star fish once roamed in the ancient sea now known as "Taughannock falls" today? Because a research team is trying to find this specimen and they are wondering if anyone has discovered it. Edit: Im referring to the dotted trackway. check this link out for more information. http://www.wvgs.wvnet.edu/www/news/Pteridichnites.htm

Had some help with the ID on these. Apparently they are fossilized Ghost Shrimp burrows. Probably Eocene period based on the Matilija Formation Sandston but possibly Miocene. Also some Turritella shells too. Specifically in the Rattlesnake Canyon tributary of Matilija Canyon in the Los Padres Mountains of Southern California. TTT

I've had some great hikes this month with such a variety of finds. I walked several miles rock hounding and my legs were tired. I sat down to hydrate and debate if I should continue when I looked down and right in front of me was the cutest little fern. I was lucky enough to find the matching halves in the same spot! Just the energy I needed to keep going!

Here’s one for our resident ichnologists. This is far out of my league to id. Found in Branson MO, it’s limestone. Bunch of ripples where I found this. I don’t know Branson strat, so unfortunately that’s the most info I can give you. The trace in question is roughly 1 cm wide. Thanks in advance!

Hi everyone! I believe I have found trilobite (or other arthropod) tracks. Photographing was challenging. They are not the best but I believe visible enough to identify…hopefully! I found this in Crawford County, IN. Any help is appreciated!

A Wealth of Trace Fossils from Saskatoon, Saskatchewan!
Pseudogygites posted a topic in Fossil Hunting Trips
Another day of great finds in Saskatoon! This time, some trace fossils. With my wonderful collaboration with the University of Saskatchewan's Museum of Natural Sciences still continuing, recently I have been very lucky to make multiple trips out to a beautiful site just outside the city of Saskatoon where massive deposits of glacial lake silt are exposed. This silt produces pristine grass and other plant fossils in abundance (I'd like to make a post about them soon as well), but also seems to be teeming with various invertebrate trace fossils. All are very small (under 1 centimetre wide). I've attached some of my best pictures below. 1 - 6: Overlapping Planolites sp. closeups 7 - 11: Edaphichnium sp. 12 - 14: Taenidium sp. closeups 15 - 16: Taenidium sp. wide shots 17: Taenidium sp. closeup

Hey gang, Going thru chucking things out of the garage piles and noticed this good sized, highly weathered chunk of bone which has some parallel grooves/marks that I'm interpreting as possible shark bites. Want to confirm that assumption and ask if that is the case, could the upper 3 somewhat parallel lines and the 2 lower lines be single bites showing 3 teeth and 2 teeth respectively? The one mark on the upper left seems to be slightly curved so would that be consistent with a different angle/different shaped tooth position? Just wondering what you all think? Regards, Chris

Hi everyone. I was up in northwest Pennsylvania a few days ago seeing some friends and found this wild thing on their property. It's not my usual hunting grounds and I wasn't particularly looking for fossils at the time, so I never bothered to do research on the area. What I can tell you is that it was found in northern Crawford County, PA, which I believe is Devonian (but may also be Mississippian). Nearby were some brachiopods in sandstone. If extra pictures are needed, just let me know. Please help!

Found on a spoil pile in the Mazonia wildlife management area, northern Illinois. I've found a couple other cool trace fossils in the area. Is this one ?
