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

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.

Last week I was hunting in my usual location in Allegheny County Pennsylvania (Glenshaw Formation) and found that several of my specimens have splotches of what appears to be pyrite crystals. With some of the broken fossils I could see that even the insides contained gold-colored pyrite. On the other side of these plates were what looked like rootlets covered in a pale green mineral. Is this pale green mineral pyrite as well? Is there some way I could test this? Thanks for the help.

Hello all, I recently ordered a big piece of Wheeler Shale and have had loads of fun splitting the rock and finding Trilobites. I've got a nice complete specimen of each of the common species (Kingii, Wheeleri, Interstricta) as well as a ton of molts, cephalons, and pygidiums. I am a new prepper and thought this would be a good way to start, though my dream is to eventually learn how to do Moroccan or Russian trilobites. I've been practicing on the molts and parts of the trilos, but the head I am prepping currently looks like it is pyritized. It's got a few pyrite pieces on it, but

Curious about iron and pyrite in the Hell Creek Formation
Maniraptora posted a topic in Questions & Answers
Hey all! When I went on a collecting trip in the Hell Creek Formation in Montana, there were many iron concretions, and I've noticed that some specimens from there appear to be iron-stained. This makes me wonder if pyrite could be among the minerals involved in fossil preservation there. Are some of the bones found in the Hell Creek pyritized, and how could those be distinguished from others preserved differently? If so, do those Hell Creek specimens ever develop "pyrite disease," and what would be the warning signs to look out for? Thanks so much for sharing your knowledge! -
Found this at warden point, Sheppey. Wondering if it was a seed?

Found this at the weekend on Charmouth beach, the black flakes look like scales or possibly bone. We looked at hundreds of bits that morning but nothing else like this, any ideas?

3 New Spots; 30 Days; 300 Million Combined Years of Mosasaurs, Sharks, and Mysteries to Discover
EPIKLULSXDDDDD posted a topic in Fossil Hunting Trips
Apologies for the dramatic title. I thought it sounded cool and stuck with it even though 90 + 80 + 80 is only 250 . Anyways... This past 30 days, I decided to make it a point to check out some new spots. I won't be living in Austin soon, so I thought it would be good to branch out and scout some new locations with potential. I've found lots of creek-worn mosasaur bits and pieces over the past year. I'm ready to find things in situ, and, one day, something articulated. It's a tall order, I know, but I feel like it's the next step and really the ultimate goal I've always had. So, th -
Hello, in my quest for jet and amber I came across this piece this week in an old mine. This is the first time that I have found a piece of good jet covered with its bark totally pyritized over several millimeters. I find the result very pleasant but I fear for its stability in the months or years to come! This dates from the Turonian and the abandoned mine is in Languedoc Roussillon in France!

Back in January I decided to check out the Ammonite Beach at Lake Texoma for the first time. The site is well known for its giant Duck Creek ammonites that can be found scattered all over the shoreline. The weather was surprisingly not that bad despite it being the winter. The water level was quite low and there was plenty of good ground to search along. During my time there, I had some success in finding my own ammonites which gave me an excuse to finally put my rock hammer to use. I stumbled upon some echinoids, but none of them were in all that great of condition, so I might need to head ba

Hello, I've recently collected some fossil wood from the London Clay. However, I have heard that it is prone to pyrite 'disease'. I've cleaned the wood with water, and plan to keep them with packets of silica gel to reduce humidity. Will this be enough to prevent pyrite oxidation occuring? I've just attached some photos of some of the wood that it can be seen on. There is also this white-coloured material on this bone. Is that anything to be concerned about? Many thanks

Found these two fossils? In some limestone brickwork. What are they?

One is pyritized and I have no clue what it is. The other I’m thinking is a plant? Found alongside loads of crinoids -
Where to get Paraloid B72 in DFW and Other Questions
EPIKLULSXDDDDD posted a topic in Fossil Preparation
I've been recently looking into working with b72 for preserving and strengthening some of the pyrite and coal fossils I have. At the moment, I have a few questions regarding this topic: 1) For DFW folk, do you recommend any stores that sell b72 in the DFW area? For others, do you recommend any reputable online stores that ship it? 2) Should I store acetone in the original container I purchased it in? What is the safest part of the house to keep it? 3) What are any general tips/tricks you wish you knew before you started using b72? Feel free to answer as few of -
This one has been sitting in my "interesting but I have no clue" pile for a while. When I found it, I was splitting limestone laying in the stream. I've found that when you split limestone, immediately after splitting you'll get a couple moments of a sharp looking specimen before things start to oxidize. The limestone is a very dark gray, or almost black color. You either see black limestone or white calcite pieces while splitting. I split this particular piece open and right in the middle was a 3-4 cm long, 8 mm wide gold looking rectangle in the middle of the flat broken limeston

I would be grateful for help with identification of this ammonite. It is Sinemurian and found in Gloucestershire.

Hey everyone! I thought I'd share a few of my finds from the past couple months and get yall's opinions. Over winter break, I went back home to North Texas and did some searching around Ammonite Beach at Texoma and the NSR with my family. At Texoma I had a nice time hammering out a few ammonites, collecting teeth, and surprisingly finding lots of smaller, pyritized ammonites that I did not expect to be there. The NSR was a bit slower, but I at least got a nice Squalicorax as shown in the pics below. Since school has started, I've been down in Austin. I've been finding the usual stuff, but the

Pyrite Decay in Crinoids from Corey's Bluff, Crawfordsville Indiana?
Mochaccino posted a topic in Questions & Answers
Hello all, I hear that crinoids from a site known as "Corey's Bluff" of Crawfordsville, Indiana tend to be susceptible to pyrite decay. I don't know if this is a pattern but I've noticed a few crinoids from this location having black spots that I'm told are pyrite. Could I ask any members who've dealt with these crinoids or heard of this speak about their experiences? I noticed @Harry Pristis for one has some very nice crinoids from this site with such spots. I'd really appreciate any and all thoughts. Thank you. -
Hello, I went on a trip to Lyme Regis, U.K. last week and came back with some lovely pyrite ammonites and a small ichthyosaurs vertebrae. However we also found this. I’m not sure it’s a full pyrite piece (6cmx6cm) as there is an impression of an ammonite however there are these pyrite cone shapes. Are these just Echinoids Or have I got really lucky with some shark teeth? (very unlikely I know!). I only came across this last one via the National History Museum fossil app which has a picture of a Hybodus delabechei teeth and it looks very similar from a top down view on to the tooth

Hello, I'm looking at this ~5cm Ohio Silica Shale Paraspirifer bownockeri. I was wondering if such bright gold coloration indicates "enhancement" of the pyrite by harsh prep, acid treatment or brass wire brush? Or is this just the natural color of some specimens? Many pyritized Paraspirifers I see are more grey or silvery (though I have indeed seen such gold ones). Other pyritized fossils as well seem to typically be more the silver/grey color, and as far as I can tell Pyrite itself is generally paler than a vibrant gold. Thanks.
