What's covering my plesiosaur vertebra? How to clean
pachy-pleuro-whatnot-odon posted a topic in Fossil Preparation
Hi all, I recently decided to buy the below plesiosaur vertebra after having seen it for a long, long time. It dates to the Callovian of the Oxford Clay and was found at Peterborough. I suspect it may be attributed to Muraenosaurus leedsi, as it comes from a cryptoclidid plesiosaur, but is both larger and more elongate that the typical Oxford Clay Cryptoclidus vertebrae I'm familiar with. Supposedly coming from an old collection, it has a blackened exterior that doesn't cover the entire piece, with the more common buff colour visible underneath. As such, I expecte -
Hello everybody! In continuation of the Frozen Fossils and Frozen Fossils II topics this report covers fossil hunting in real winter, with excavating fossils from under the snow (@JamieLynn might be interested). The trips took place this week when we had a thaw with temperatures raising to +1-2 Celsius after a long period of frost (so that digging became possible). This time I visited the same site as in FF2, which is MUCH poorer than the one covered in FF1, but MIGHT yield more diverse fossils (which was unfortunately not the case).

I’ve been slightly obsessed for a long time now with finding a Whitby cannonball nodule good enough to put the hours of prep work into. I have given up while trying to split many, I have split a lot of empty ones, I have chipped a load while trying to split them. I do have a nice eliganticeras nodule that could potentially polish up but the shape just doesn’t lend itself. I found this at the weekend at Runswick Bay and while it would have been nice to have a split nodule with the positive and negative, I could see the potential in this. The actual ammonite is just a crushed up pyritey me

These are two of my favourites, which I have been working on with my dremel to remove matrix. Parts of both show a fantastic golden pyrite. Sorry the pics don’t show it too well. I suspect the gold is fading however. A few questions: 1. Can I do anything to bring out the gold? Would polishing with a wire dremel head help? 2. What can I do to preserve the gold? Should I coat/seal them? Thanks in advance!

Ive seen pyritized plueroceras ammonites that look golden, like this one, but there is also this one that is the same species from same location with same pyrite but not as shiny, is the difference just one is polished and one is not? Thanks for the help

Found on limestone river bank in Alabama. There were fossils nearby (shark teeth, shells, some kind of vertebrae) but not exactly where these were found. Can’t see in the photo but there are tiny gold looking flakes in it.

My grandmother (rest her soul) was a high school science teacher way back in the day. She was also a SERIOUS rockhound. These days her extensive collection of odds and ends lives in the family attic. I was going through some of the boxes when I stumbled on this gorgeous pyrite encrusted brachiopod. Unfortunately many of the tags and labels for her pieces haven't survived into the present day, so I've been curious about what species this is and where it might be from. I've heard that Ohio has a deposit with lots of pyrite fossils and brachiopods. Anyone know of any other places where such a fos

Hi there, I found this specimen on a hike outside of Denver, Colorado. It was laying in the middle of the trail. It’s about 10cm long. It has grain that looks like wood or layers like mica. It’s also gold and shiny like pyrite or mica. It’s layers are wavy and it leaves a gold dust behind when handled. It’s stunning when the light hits it. Hoping to identify what it is. Thank you! Lisa

It appears to me as a pyritized wood, it gave off the metallic sheen when it's under the light. Pyrite/marcasite are abundant at where I found this and it's from Kiowa formation (Albian). Kiowa formation is primarily an estuarine and shallow sea environment, fossilized wood and plants are occasionally found from there. I found it as a concretion but it crumbled into tiny pieces when I pulled it out of the ground, so this one is the largest and only piece I have now. Do you think it's a pyritized wood?

In 2013 I was visiting around Buffalo and went to a creek that had been recommended. I didn't come across any trilobites but did find other exciting things. Among them were quite a few pyrite nodules I dug out of the creek bank. Must have found 30 of them. All rounded but varied shapes. About the size of a quarter or a little bigger. I have learned that many people have found them. Some close-ups. Many have a hole in them (shown above) and you can just barely see something inside the hole. Early on I broke some of these open and found...

New Jersey Cretaceous Pyritized Lignite Prep
The Jersey Devil posted a topic in General Fossil Discussion
Hi everyone, I would like to hear any recommendations for prepping pyritized lignite. I am about to try the PEG technique that @LoneRanger described in this topic: http://www.thefossilforum.com/index.php?/topic/19304-preserving-lignite-fossils-with-polyethylene-glycol/ This should stabilize the lignite. However, I don’t know if the pyrite will also stabilize. I don’t want it to develop pyrite disease. Would the PEG coating be enough to protect it from air humidity? Thanks a lot! Here is a sample of some of the material I am prepping:- 17 replies

2 inch by 1/2 inch with Crinoids, Bryozoans, more and did not expect to see the 3/8th inch 0.9 cm pyrite on it. Allegan County, Michigan From my dig site Yesterday. I believe it is limestone. Would like the approximate age for the fossils and about when did the pyrite form on it?

Okay, Fool's Gold and Sand Dollars, but hey, I prefer those anyways!!! So yesterday was my birthday and I had a 6 hour drive home from a convention I was working and thought, hey, I'm KIND OF close to a fossil hunting spot I had heard about so I took a short (two hour) detour to check it out to see if I could find anything. And oh my goodness did I. This is a very very small grown over spot in East Texas, down a back road. I came across this beauty first thing but left it since it was too shattered to try to retrieve, so it sits in situ as it should be. I hope nobody ever disturbs it.

Collected in 1994 in Cropwell Bishop Nottinghamshire UK, some Rhaetic pyrite layer pieces from a Gypsum mine. Packed full of bivalves, fish teeth and coprolites. Focusing on this particular find, would anyone know what it may be (1st picture) 1mm scale.

Leicester Pyrite Member. This layer between the Windom and the Geneseo black shale represents a sea of death. I find very few types of fossils in this hard to process layer of solid pyrite. Well preserved cephalopods and Placoderm armor (Placodermi is a class of armored prehistoric fish) are the most common fossils found. This very thin horizon can be easily found in the outcrop if you just look for rust dripping down and staining the grey shales below this pyrite layer. Every year or two, a piece of Leicester Pyrite will fall from its position high up in the outcrop and slide dow

This is my current labelled collection. I have other stuff that I found on a fossil hunting holiday in the South West of England, but I’m very amateur so I don’t actually know the scientific names for a lot of them. Everything on this shelf was found except the teeth on the left and right, which were bought on the Isle of Wight. Essentially everything on this shelf was ID’d by members of this forum, except the pyrite and favositid, which were ID’d by friends, and the igneous rock and ammonites, which I didn’t feel i needed to have ID’d. The ammonites are my pr

Went to a beach in the Whitby area today, it was very slim pickings until my daughter saw the first of these items shining amongst the rocks. I’m guessing some kind of pyrite bivalves? The second item is something I saw on our way off the beach, am I right in thinking they’re crinoid stem sections? Thanks in advance

I recently acquired a collection of assorted rocks and minerals. Many of these specimens are from the 70's, 80's and 90's ( am in the US). In this group there is two ammonite in matrix specimens. I believe they are Russian due to them being pyritized. I am having a difficult time finding info about what species and what value these specimens may have. I go to the Tucson show every year and I don't often see ammonites like this. I was told to come here to find the experts! Thank you for your time, I look forward to posting more
