Folks, I am a newbie and this is my first post. There is a single 12 inch square siltstone tile in my bathroom that has been driving me nuts. It looks like it may include a few examples of a fossilized arthropod of some sort, but then could also just be a product of its lithogenesis… or my imagination, for that matter! Attached are some photos of two of the suspected ‘fossils’ in the tile…but, to be fair it is speculative at this point to call this a fossil unless someone with a lot more experience in this forum can suggest that may indeed be the case. I would love

Ethiopian Amber (Debre Libanos Sandstone; 23-16 Ma)
Barrelcactusaddict posted a gallery image in Members Gallery
From the album: Fossil Amber and Copal: Worldwide Localities
4.7g polished specimen of amber from one of several deposits near Alem Ketema, Amhara Region, Ethiopia; piece measures 35x24x17mm. There is a thin vein of transparent material, while the rest is heavily included with organic detritus; some small fragments of plant material are seen in the transparent portions (see associated photo). The green coloration is partly due to the amber's autofluorescence initiated by the LED light (transmitted) during photography; the clear portions of this specimen present a yellow-green base color in incandescent light, and emit a greenish fluorescence in sunlight© Kaegen Lau

4.7g polished specimen of amber from one of several deposits near Alem Ketema, Amhara Region, Ethiopia; piece measures 35x24x17mm. This view of the specimen displays organic detritus inclusions: in particular, a long fibrous subject (at center, beneath fluorescent layer) can be seen. The green coloration is partly due to the amber's autofluorescence initiated by the LED light (transmitted) during photography; the clear portions of this specimen present a yellow-green base color in incandescent light, and emit a greenish fluorescence in sunlight or LED light.

Hi all! I pulled this fossil out of Red Hill, a Devonian site in central Pennsylvania. I thought it looks like it could possibly be part of a placoderm but I’d love to get some help with further identification. Thanks in advance!

This plate was in with a bunch of other fern fossils I picked up. What all can you tell me you see in it please.

The other day I posted trilobite pics in this ID page thread I just used a beat up drywall saw to cut the section with the trilo out of the slab, then tried to "split" the whacked at the rest of it hoping for more. The siltstone (noncalcareous dolomite maybe?) was so soft it just crumbled. I tried tapping around the edges, which just sort of mashed in, and also tried a chisel, which just took off crumbly flakes (and I wish that was as easy when I try to nap flint). I knew if I found another specimen I'd destroy it trying to get at it, but went for it anyway as a technique-lear

First Trilobite, need help with order or genus.... Alas, it's from the Garbage Formation
SteveE posted a topic in Fossil ID
Not counting lits bits and piece, finally found my first trilobite. It goes to show that you can find fossils in unexpected places, too. I was waiting to meet a friend and was just kicking over rocks in a misc (man made) rubble heap on the edge of town. Then this fragile soft siltstone broke apart badly, right across this beauty. I have no idea what formation it's from, and since its a junk pile along an abandoned RR I can't say for sure that's even from the county (Hollidaysburg, Blair County, PA, USA). About all I can say is it failed the fizz test, and there is a lot of parallel colo -
Former Floridian trying to restart the hobby in the PNW
winnph posted a topic in General Fossil Discussion
Hi everyone, Once upon a time, I was a young college student at UF whose favorite hobby was spending hours trudging through swamps and up and down creekbeds in search of gravel beds and limestone banks. There were no other types of stone worth noting, so every stone was either limestone or imported. Fossils might not always have been easy to find, but when you did find them they generally were sturdy things that were practically falling out soft limestone or clay. My tools were a hand spade and a homemade screen in a wooden frame, that's it. Fast forward a decade (or tw-

This was a prep I've last year, but for some reason I've never posted it on the forum. So I thought I might change that. Last year I was fortunate enough to take a visit to the Ernst Quarries and dig for some shark teeth. Although most of the fossil I've taken home are either bones, four partial regular-sized teeth, and mostly tiny partials (some of which I accidentally damaged while digging ), the biggest find of the day was this large Cosmopolitodus hastalis tooth with its crown partially sticking out of the matrix. When Rob noticed the tooth, he initially estimated it to be ~2 i

I'm having a hard time figuring out the formation of the fossils I found today. The layer is about 4 feet wide. Fresh it appears to be a gray shale. It weathers quickly to a buff very soft siltstone with pale purple swirls. Some fractures show a colorful (red, orange, yellow, black, brown) iron staining. The PA geologic survey map for Altoona marks this as a Brailler formation area but that formation's description doesn't seem to fit what I found. Does this description sound familiar to anyone? If pics would help I can take some tommorow.

Hello all, I found this piece about a couple months ago while searching for dinosaur prints in cretaceous siltstone. I'm not sure what it is, it is raised and could potentially be some type of depositional feature or erosion pattern. What do you think?

I found these hunting for arrowheads in northern Upshur County. They were on the surface downhill from a knoll after recent rainfall. It's a sandy "red dirt" area, with what I think are some scattered hematite and sandstone or siltstone rocks and pieces. Are they fossils? I'm new to fossil and rock hunting. This is my first post
