    Brachiopod? Or USS Enterprise?

    Found near Altoona, Clinton Group, Silurian. Is it a brachiopod? And what are the vibrant yellow and red parts? Is it from mineralization? Thank you.

    Fossil Fern

    First Post! I looked up online where I could possibly find fossils in Rhode Island, and I think I found one of the more popular sites. Unfortunately I visited the site during high tide, but I was able to discover a fossil fern. I ended up leaving the fossil at the site since I don't think I could have kept it. Attached below is an image of the fossil fern I discovered. From my experience at this location, you do not need tools to break apart the shale because the shale at this locality is extremely fragile. A small hammer and chisel could be handy to pry apart more stubborn rocks.

    Impression? Trace fossil?

    I’m an intern in the history collections department of a museum and the soon-to-be ex-husband of a geologist just donated six boxes of fossils, rocks, and minerals to us. Unfortunately I am the only person working in collections, and I really specialize in history. I don’t have any fossil knowledge at all, aside from the research I’ve done the past few days, and we don’t have a lot of information about the specimens donated. All we know is that some came from Germany and some came from various US states (but we don’t know which ones) and I believe many of them were found in the 80s based on th

    Texas Plesiosaur Vertebra?

    After finding my pyritized ichthyosaur vertebra in the Grayson Formation last Friday, I decided that it was time to revisit previous exposures I had first discovered three years ago with a fresh set of eyes. I made a trip to several of those spots the following Saturday and one of the fossils I found is another vertebra. I initially wrote it off as a fish vertebra because it was so thick, then decided it wasn't flaky enough to be fish and the two holes on one side meant it must be a shark centrum, then thought maybe it could be an ichthyosaur caudal, and as of now I think it might be a plesios

    Heteraster cf. texanus

    From the album: Texas Albian (Cretaceous)

    Heteraster cf. texanus Albian Texas Found at the legendary "anti-wishing well" - a site shared by my step brother and I. It's a tiny prolific exposure of comanche peak shale behind a little waterfall in a beautiful area with excellent rock climbing and great memories.

    Possible Phytosaur tooth?

    Went fossil hunting in the cumnock formation of North Carolina and as I was rinsing some of my dirty fossils one of them caught my eye. The curved shape is what threw me off and reminded me of a tooth. I double checked on here and saw another person that had something that looked similar to this and was a tooth. But just be sure, wanted to see what you guys think. Your input is appreciated! (Bottom picture is the confirmed Phytosaur tooth)
  7. Hi everyone, I'm a first time fossil hunter and I went up to Turimetta head north of Sydney with a friend to try our luck. We found a few things splitting shale, and I was wondering what exactly they were - I understand that they're all probably plant material, if they are fossils, but wasn't sure exactly what type of plant they were from. Hopefully someone can help. Thank you in advance!
  8. Hello, NW Indiana here. They were doing some digging and in the sandy glacial deposit ish layers, I was finding some heavier sandstone conglomerates with Devonian era fossils(crinoids, shells etc) , and I also found some shales, they appear to be newer but I’m not 100% sure. Most are pretty flakey, haven’t found anything fossil wise inside (that could indicate a time frame better) but one of them did have a strange triangular shape inside. My question is, is it possible for other rocks to be in this type of shale? And that is just potentially what it is? Is it potentially something else? I bro
  9. Over the last 10 days I have made three trips to an outcrop in NY that exposes some Silurian material. After doing some research on the stratigraphic beds that occur in this unit I decided to head out and give it a shot. As soon as I showed up on the first day I found a negative of a complete Dalmanites sp. trilobite on a large boulder that someone decided to leave behind. I did not see any more than partials and brachiopods for the rest of the first day. I had much more success on the second and third day. Plenty more not pictured such as corals, brachiopods, and trilobite partials. Spent som

    Shale/mudstone fossil or mineral?

    I am back with another one I cant quite work out! Being quite amateur I am still learning, so apologies if I'm mistaken on rock type etc. This was found on the jurassic coast of the UK, on the beach near Charmouth and is in shale/mudstone so already trying to break apart as you can see. I've been wondering if it's a sponge or root of some kind, or just mineral like pyrite as it has a goldy metallic sheen in some light, although it seems too brittle for that and has got what looks like more calci(?) layers when I look at the ends. Any help from all of you lovely lot would be grea
  12. Last week took me back to my home state of Ohio in order to attend a conference. On the way home, I stopped at the Paulding Fossil Gardens to play in the Silica Shale for awhile before returning to the white landscape of Minnesota. There are a few unknowns that I ran across and am hoping for a little help! @Peat Burns These tiny squiggles are on top of a bryozoan covered brachiopod. The pores of the bryozoan can be seen. IDed as Microconchids. I thought this was a bryozoan until I looked at the enlarged picture. Now I feel it is crinoidal, but what?

    Unusual Carboniferous Plant Fossil

    Howdy! This specimen comes from the Pennsylvanian Period, Conemaugh Group, Glenshaw Formation, in the Mason Shales below Brush Creek Limestone. The area has a lot of Pecopteroids, Neuropteroids and Calamites. However, I've been informed that it is not Calamites. I should also note that this piece was part of a larger fossil cast that was crumbling apart when I found it, and unfortunately, I was unable to save the rest of it. The last picture is the back side. All help is appreciated and thanks in advance!
  14. I found some pyritized plants a few days ago and noticed that one looks like a stem with seed pods. The fossil measures 2 cm and is from the Glenshaw Formation of Beaver County Pennsylvania. I'm nearly certain that what looks like a stem is a stem, but what are the three round things seemingly attached? Help is appreciated, thanks.

    Plant fossil ID

    Hey new member, Found this fossil at work. It is in shale rock and there is what appears to be ferns through the layers. There have been a fair few big and small. Found in Queensland Australia

    Is this a Calamite?

    I collected a number of these as a kid some 50 years ago. Only one is like this. I just thought I should try and identify it. I had always assumed it was a small tree trunk. Seems to match pictures of a calamite trunks (a new thing to me) with the distinctive ties at regular intervals. It comes from the old mining town of Brownhills UK. Coal, sand and clay were mined there. This came from the edges of an open pit clay mine. I went back to the site a few years ago but it's reclaimed now. You could still dig small holes and find fragments. So my kids found some. You just needed a bucket of

    Yunnanozoon or something else?

    The longest one is roughly 2cm long. I’ve counted 12 on the rock, which itself is about 5cm long. All I know is that it’s from the Maotianshan shales in China. I was told it’s a Yunnanozoon, but I believe this is incorrect as the person I got it from is often wrong with their identifications.

    Odd shapes in shale

    Few weeks ago started breaking open some pieces of shale. I've found lots of trilobite fragments that I'll post later, but what's intriguing me is these small bits of things that I find quite a lot. I can't find anything on what they might be and my closest guess is perhaps some bits of crinoids? Does anyone have more experience than me with such things?

    Is This a Cambrian Monoplacophoran?

    Hi I came across this while hunting for trilobites at a commercial Cambrian shale quarry in Utah near Delta and was wondering if it was a monoplacophoran or something else or just an odd rock formation. The shape is concave and about 2 inches in diameter. Any help would be much appreciated. Thank you!

    Unfortunately I don’t have any provenance for this rock. I bought it years ago screwed to a piece of driftwood for my fish tank. When the driftwood had withered away to a twig, I was throwing it away, but noticed the fossil traces on the rock and kept it. Came across it a few weeks ago, and started messing with it. The fish store was local, and I would assume that this was created by a somewhat local person (in east TN), but I don’t know. The top of the “calyx” is translucent from the underside. Not the softest limestone I’ve found…I can see signs of bryozoans and brachiopods, but it’s hard t

    Insect fossil?

    Hello My first post, Nice to meet you all, in advance. I am an amateur geology enthusiast/fossil hunter. Purely as a hobby and for my personal enjoyment. I found this stone in a very unusual place, stuck in the tire of a piece of construction equipment in The Netherlands close to Rotterdam. Pure random chance. Not where I would normally hunt. Unfortunately, this piece of mobile equipement could be used all over the country so it is impossible to say exactly what its origins are. It looks to me, to be a piece of shale or oil shale that has spent a considerable amount of
  24. Being a Colorado native, I have taken multiple trips to the public-access Florissant Fossil Quarry located near Florissant Fossil Beds National Monument in Florissant, Teller County, Colorado. This quarry provides fossil collectors fantastic access to the shale layers of the Florissant Formation, a late Eocene (Priabonian, ~34 million years old give or take) lagerstatte known for its diverse fauna of fossil insects, in addition to plants, gastropods, and very rarely vertebrates. Most fossils occur in very thinly laminated ashy grey shales. Other lithologies present include well-sorted tan cour
