  1. Alongside some great ammonites I found these three strange things amongst the Jurassic Whitby Mudstone, none of which I recognise. Any help is much appreciated.
  2. This is a shot of a conglomeration of fossils in mudstone from the Verde Formation of central Arizona. This formation is a graben of jumbled types -- sandstone, limestone, mudstone, basalt, etc. These were in layers along a dry streambed. Any assistance with what they are would be appreciated. I'm assuming they are Pennsylvanian period, given the lack of crinoids. Locally, the redwall limestone is Mississippian, and contains abundant crinoids. The Martin limestones are Devonian, and have few fossils. I assume the pictured fossils are more recent than either of these. I'm especially curious abo
  3. I found this in Eastern Colorado between Denver and Ft Morgan I thought it was mudstone, and had a lapidary cut it so I could see a cross section wondering if it could possibly be coprolite this piece is 5x4x4 inches -12x10x10 cm and if it doesn't show well in the images, it is twisted in appearance

    Mudstones?

    Hello all- I live in NC, the far Western part, but spend a lot of time in TN, at a man-made lake that was constructed as part of the TVA project, beginning in the 30s. The rocks and scenery around there have been stirred up and relocated with the construction of the lake, so it’s kind of difficult to say what ought to be where. That said, they consist mostly of rather uninteresting dolomite and quartzite in the forested areas, and then huge beach expanses of orange-tan to red to purple and even bluish clay-type slate or shale material that has hardened in spots to near-ro

    Brachiopods

    One from yesterday. What we call Michigan Devonian mud stone. I would like info on the large Brachiopod type, Mucrospirifer ? I do realize it is partially missing. I am not sure if sodium bicarbonate will clean up a lot of areas? Or how much it is worth doing. images 2-3 I call the bottom side, showing material under the holes. Thanks.

    Trace fossils? Coral? Anemone? Worms?!?

    Hey there! This is my first post on The Fossil Forum. I don't have a lot of knowledge about fossils, but I sure do know how to find them. Hopefully these aren't too obvious and boring, but I'm incredibly curious anyway. I found these near Sheep Bridge north of Phoenix, Arizona. Here the Verde river has cut through deep layers of ancient lava, sandstone, mudstone, etc. I was exploring for crystals up on a steep hill along the river's canyon walls when I came across a whole lot of these things. They are very fragile and I didn't want to break apart some of the 2-3 foot wide boulders of th
  7. Does anyone have any tips or tricks for how to keep mudstone from cracking and delaminating as it dries out? I recently went to Clarkia in Idaho and came back with a few fossils, including a flower, wrapping them in newspaper and putting them in the fridge as was suggested. They are beginning to crack and delaminate. I was hoping someone could help me think of a way to keep them solid before the leaves are broken. Thank you.
  8. Hello everyone, I was able to make a run down to the Conasauga River trilobite hunting site yesterday that was suggested to me in another thread. I didn't have an overabundance of time, but within five minutes of arriving, I found the specimen in the attached photo. It's not perfect, but it's the first time I've ever found a fossil out in the wild. Thank you to everyone for pointing me in the right direction. Now, since my time was a bit limited, I collected a five gallon bucket of the mudstone found there to look through it later. Now, some pieces seem easier to split

    Fish fossil identification

    Could you please identify these fish fossils?
  10. Paulie777

    Would this rock have fossils?

    This is a very large boulder and it is layered. I took off a few layers and found nothing. I was wondering how old this boulder is and should I keep digging into it. Thanks for your help in advance.

    Leptaena

    I collected this Leptaena brachiopod from the red brown mudstone resting three feet above the top of the first out crop of breccia limestone. The location is above the rest-stop on highway 89 S before Riceville Rd. The formation is the lower part of the Kibbey. Leptaena Brachiopods dominate along with three types of bryozoa and crinoids. Also found clams and a part of a plant fossil. The setting was once a lagoon.
  12. Hi everyone! For the last few months I have been finding lots of fossil imprints in mixed chert cobble on a artist residency/farm in Kingsbury, Texas near Seguin (in Guadeloupe county). They are digging up some of the cobble/gravel to line the roads and walkways on the farm, which means that everything gets spread out nicely! Plus there is the 'quarry' itself. The USGS map says that the area is Wilcox Group, undivided, and/or Willis Formation, and I am looking at mudstone, chert, a little bit of sandstone, gravel, some petrified wood. In terms of age I think it matches up with Eoce

    Pseudo or other?

    I have been looking at this and can't decide if it's something or not. I leave it to the experts. Personally I thought concretion until I saw the belt. It looks like a squashed acorn, but I don't believe there were oaks in Lower Cretaceous. Thoughts? No, it's not a human artifact.

    Fossil rich matrix

    Just a post to show what this garden patch is made of. This is a typical bucket full of chunks turned up by the plow last year. This patch will be finally tilled this year and seeded over. (might come back later, tho) I guess this is called mudstone as it is just a solid glob of fossils. Here are some pics of one of the chunks before, and after splitting. Very busy in there and quite difficult to get it to split where you want, partly due to being exposed (partially) for a year. Working on the new plow, hope to bust up a new patch in the coming week. Regards.
  18. Hi guys, a friend of mine is setting up a little prep workshop for us to use and asked me to find out about what sort of gritscan be used (we'll mainly be prepping teeth, scales bones etc. from a relatively soft mudstone), I know nothing about air -abrasion so was wondering if anyone could give me any advice, any help would be greatly appreciated!

    Peace River Plant Impression?

    A friend and I went out on the Peace River yesterday. The river is the lowest I've seen...32" below normal, so much of the bank was exposed. In the area we were hunting, I decided to check out the mudstone bank...located between layers of limestone, and in separating a layer, I came the smaller impressions below. It looks so plant like to me: reminds me of the edges of hydrilla, but am so unsure what it could be. I included a close up so the finely tapered ends would show, as well as the somewhat ovoid edge impressions. I was excited, but I also know looks are deceiving. ( when I was first l
  20. Hi, Bit of a geological question here, I recently took this photo of some of the Upper Hamstead Member strata exposed on a headland at Bouldnor Cliff whilst out collecting. I really like this spot as the colour variation in the beds is really interesting. I've heard that the colour mottling in mudstones such as these can be indicative of the paleo-environmental conditions they were deposited in. Generally speaking these muds were deposited in ponds, lakes, and sluggish waterways on a low lying coastal plain. However, would it be correct to presume the redder areas indicate more ar

    Bivalve with foot?

    Sorry for the shadow/light. The whole fossil is about an inch long. Is that the foot sticking out at top left? Or do you think it's just that the rest of the shell was broken off and never became part of the fossil? It's very soft mudstone (can scratch it with my fingernail), but I know soft parts don't tend to get preserved. This is another beach fossil, so I don't know anything about the age.

    Trace fossil or jellyfish

    Hi, I'd appreciate some help with this one, it's got me completely foxed and I can't find anything similar online. The matrix is a mudstone, it was a loose rock in a stream, the rocks in the area are all Brigantian (Upper Visean) - Carboniferous Cyclothem deposits (Northumberland, UK). There were 3 of these, all about an inch long, oval shaped, but fairly irregular, with faint radial lines/corrugations from a central 'spine'. They are three dimensional about a quarter of an inch thick. Small spiriferid brachiopod shell fragments in the same rock are undeformed, so I think the irregular shape i
  23. Hi everyone! I was playing around with some matrix fragments from the phosphate deposits of Morocco and decided to give it a dip in water to see what would happen. What surprised me is how quickly the pieces crumbled into tiny clumps. Practically 80% of the matrix was gone in less than 10 seconds, dissolved by the water. I could very well have picked up a piece from dried mud and it would give similar results. I always thought the Moroccan stuff was a kind of sandstone, but what I saw suggests it is more of a clay-type rock? Then again, can the m
  24. I went to visit my family south of Rochester, NY a couple of weeks ago. They own property which includes a creek emptying into Canandaigua Lake. Here are some pics and finds. There are public sites very close with similar fauna, including Green's Landing, and Barnes' Gully/Onanda Park. Eldredgeops Rana strophomenid Amboecoelia umbonata strophemenid brachiopod (not concava--its a flat one)
