In a previous post i showed some finds from the British Coal Measures of Derbyshire , this is a small nodule from there it measures 21mm long x 12mm wide and the longest pinnule is just 4mm . I have tried to show it's size in these 4 pictures. and just so you don't get bored looking at the same fossil here is a.... Asterophyllites Equisetiformis Cheers John

A friend of mine(yes, it really is a friend, not just me lol)apparently got these in a box of stuff, and they were labeled as being from mosasaurs. He asked if they were coprolites, but i don't know exactly how they were described. I told him no, I don't think any coprolites would be so smooth, even, and without any imperfections(I'm sure there are some like that out there, but that must be pretty rare. A random group of coprolites aren't going to all be like that, I'd imagine). I told him I don't really know and that id ask, but my best guess would be either gastroliths, or nodules. I don't think mosasaurs have gastroliths, but plesiosaurs do, and the ID of mosasaur seems bunk anyway, no matter what they are. As far as nodules, I don't know if nodules are found in that kind of site, so yeah......does anyone have any idea? Oh yeah, they're from Khouribga, Morocco.

Well, here’s another that we found today on the James River in Virginia. It’s 2.5 inches. At least I know this one isn’t asphalt!

I dont know if this is the appropriate place to ask but I thought I would go to the source to ask. Looking for people that have some crab from NZ that they wouldn't mind working a deal. trade or sell. PM me if you or someone you know can help. It's one of the fossils I'm looking to add to the collection and since I love to prep it should be a win win.

I recently bought a few collections/accumulations of Mazon Creek fossils. One of them seems to have been a collection of all fauna. After sorting out all the pecopteris ferns and such, I am left with a pile of what seems to be mostly fauna. I am not very familiar with them and don't have very much time right now to figure out the classifications. So I thought maybe someone here would like to work out some sort of trade in exchange for ID'ing these nodules for me? There are shrimp, worms, maybe a few more unusual plants, and stuff I have no idea on. I think I have about 50 nodules. PM me if you are interested, thanks!

We went up to Terre Haute, IN for a wedding this past weekend. I was looking forward to us being able to actually hunt for some fossils of our own as I had read online about Fowler Park/Griffin Bike Park and its nodules. I decided to check out the park rules after we got up there and lo and behold, Vigo County doesn't allow fossil collecting. I didn't want to set a bad example for my daughter so we refrained, much to our dismay. On the way home we stopped at an antique mall and happened to find someone selling jars of split nodules! So, we didn't come home empty-handed after all. Below are the better pieces that were in our jar. I used this guide and decided we had some pecopteris and macroneuropteris, but I'm not sure what all of them are, especially the blobby thing on the upper right. See detail photos of blob.

I just got all these fossils in bulk and was wondering if these IDs are correct. Sorry for the long post. The IDs came mixed up so please correct me if you see any that are wrong. All collected in Yorkshire. Hildoceras Bifrons with shell structure showing? Hildoceras Bifrons on a small nodule Hildoceras Bifrons with some pyrite. Arnioceras Block Catacoeloceras Grammoceras Large Repaired Pseudoloceras Pos and Neg X2 Eleganticeras Androgynoceras Boneblock with Ichthyosaur ribs and verts on the side.

Hey Everyone! Happy new year! A nodule from South Pit 11 Mazonia area split and can't figure out what it is? Millipede? Shrimp tale? I have the Wittrey book I've been looking through and I see similar features on multiple animals from his pictures. Thanks for your help!

I have some nodules I found already opened that have rounded raised or flat curved lines that go against the rest of the directional patterns of the nodule. They seem to be found in oblong or curved shaped nodules. I didn't know if these were actually fossils or just geologic formations. Again, I am afraid to get rid of anything for fear of rejecting an actual fossil in ignorance.

After freezing and thawing, I broke open some nodules from Mazonia Lakes that have some interesting patterns inside of them. These are nodules that did not show any signs of opening along any natural cleavage. The first nodule broke in half vertically when the shape (oblong oval) suggested it would open horizontally. The white material seems very thin and reflective, it reminds me of a plastic decal..Any ideas of what they could be?
-
I see these quite often embedded in limestone. I am just curious what this mineral is. Rusty in color and sometime in a molten shape rather than round.
-
I found some already opened nodules that I cleaned up. I wasn't sure if these were fossils or just mineral deposits.

Found in a house clearance in the UK so have absolutely no idea where the fossil originates from.
Spaniel posted a topic in Fossil ID
Hi, never posted before so please bare with. Found this fossil in a house clearance (Uk). It's sandy in colour across the surface and an off white (chalky) colour in exposed areas. Have included a tape measure in the pics for length (approx 10 inches). both sides (as shown) are deeply textured and it measures 3.1/4 in depth at its deepest but does taper down. (Hopefully shown in pics). Would really appreciate some help with this. PS each "segment" is divided by a very thin, but clear ridge/seam. Thanks all for your help Any more info required, I will do my best. Many thanks.

After cleaning off some already opened nodules and freezing a few dozen others I have a few that might be fossils. (I haven't been too good at figuring what is and is not a fossil so I'm not feeling very confident.) The first nodule pictured I cleaned in vinegar and am thinking is a jellyfish? The second I found as is and haven't found anything that looks like it. I checked out The Mazon Creek Fossil Flora by Jack Wittry and Richardson's Guide to the Fossil Fauna of Mazon Creek from the library to help better understand this but I still see a lot of confusing images in my nodules. I don't know if those are the famous jellyfish blobs or just nothing. I have another sample of a nodule I split that may be a fossil, I will attach the photos next. Thanks for your help.

Hi all, today I went to Mazon Creek for the first time and did pretty well! I brought home around 60 or so nodules. I already found a few that were split open while looking around. These might be just some odd mineralization but it doesn't hurt to try! Found in the south unit. Also, if anyone knows how to clean these I would appreciate any advice. Thanks!
-
Okay, today I have four more nodules to check. Again, some may be unfossiliferous. I'm expecting a few more jellies, and maybe a rock or two. One might be iron concretion, because of the crocodile skin pattern. Some , may need to be cleaned of calcite, the one from my last post is still being cleaned. If any more pictures are needed just let me know. Thanks and good luck!

So I bought thirteen Mazon creek nodules for 99 cents (am I allowed to say that?) and two fossils are apparent. The rest might be just rocks but I don't know enough to say that confidently, so for the next while I'm going to post them and I hope you all can tell me if I missed a fossil. Here are four, two is the most promising. Also, are those bumps that are on most anything?Thank you and good luck!

More Mazon stuff. I really appreciate the ID's people have supplied. Every one helps me understand what these things look like and how to ID them myself. 1 2 3 4 5 6 7 8 9

Here are the first of many broken nodules I found from the Mazon Creek formation. I want to start this by saying that one of my favorite parts about fossil hunting is taking an odd looking rock home, pouring over books and online photos until the moment hits when I can say without a doubt what species it is from. With these Mazon Creek fossils I stare blankly from the photos online to my rock smudges and nothing comes to mind. So any help with these would be greatly appreciated, I am really excited about them, the carboniferous is one of my favorite time periods, but you wont hurt my feelings if you tell me I have a great gravel collection. Sorry for not including a scale; if it will help with any of them i can go back and put some in. (The last 2 dont appear to be from nodules) 1 2 3 4 5 6 7

Last Thursday decided to get out to Pit 11, Mazonia South Unit, Illinois for a day of collecting nodules and fossils. We've had a lot of rain and Thursday was clear. With all the rain, nodules are easier to see when wet as they jump out as a bright red compared to the green forest floor. And the rain hopefully erodes some fresh nods out of the ground. I sometimes go on foot for collecting but thought I would break out the kayak to get to where I need to go more efficiently. The woods are getting quite overgrown already but I haven't been out much this season yet so I had to make do. Its pretty physical climbing through the woods, up and down hills, looking for the bright red rocks. I usually start at the bottom of hills and scour for an area with concentrated concretions and work my way up the hills scanning for fossils and nice shaped nodules to bring back for the freeze/thaw. Here's an area where you can see some of the iron concretions/pieces. This is a good place to start really scanning. Not more than 30 minutes into the hunt I spotted this! I usually don't find much of anything with detail or size when it comes to already opened nodules at Pit 11 but this one was a prize for me! I was out there for about a good 4 hours hiking, climbing, slipping, falling, army crawling, etc. on the search for nodules. I collected some fern pieces, a couple big jellyfish, and the nice neuropteris. I also collected about 1/2 of a 5 gallon bucket of nodules that are currently soaking for their first freeze/thaw cycle in a few days. A great day in the woods lookin for fossils! Here's the finds for the day cleaned up.

Is there any value in splitting chert nodules? I have a double nodule from near Fredericksburg TX appx 16" long that I am curious to look into. One end has a 1/2" hole with a chert stem sticking out that is pretty interesting. If it is worth the effort, what method would be best used?
-
Wouldnt it be great if all the nodules ive found over the last year were to prep themselves! Its gonna take me years plus a few new tools I think to get through this lot!! But on the plus side, who knows what treasures I mightifind inside them! :-D
-
Found a bunch of these things the other day while fossil hunting in southern NV. They reminded me of burnt/rusty pieces of popcorn (with crystals)! I know these are likely not of fossil origin, but I thought someone on here might be able to identify what they are. They resemble the "pyrite nodules" depicted in the Smithsonian Handbooks Rocks & Minerals guide. Any thoughts? Thank you, Zach

What is the best way to prep siderite fossils from Mazon Creek. Can tou clean them with hydrogen peroxide, or vinegar? Is the ph or acidity to volatile? Any and all help is greatly appreciated!
