Hi. Everyone thanks. Need some advice on some large 40+ lb clusters of fossilferious agate
Austin2000 posted a topic in Fossil ID
Hello everyone and thank you for letting me join the forum I believe I had joined before and I couldn't find my account for some reason it's been some years so I guess it got deleted and also I'm using my phone because back in January the apartment building I lived in burnt down and I'm staying at this motel which happens to be on a gold mine for fossils Well my question is this on the formations of the fossils in the limestone mainly the hotter limestone which is probably the older one like the green and the greenish blue and the gray I have several large pieces that look like they you know might be fun to do but I'm wondering on which way to approach it I got to get some vinegar and some baking soda and some Lodge tubs probably at the dollar store and let him soap for a few days and also I mean what's inside these formations I mean would there be like any like crystallization from the act because there's a few of them that which are crystallized which would be agate I think I'm not sure I'm a tool and die person so I mean this is new to me so please bear with me Also when I was collecting these you'll see by the pictures I mean I got a few of them because like I said I'm stuck in a hotel and only thing to do is walk up and down the river and I found some triangular ones which are also extremely heavy and I think they're also like the green Crystal type ones inside I'm not sure has anybody seen these before and they have some pretty good fossils on them on the outside in depth are about probably a half inch into out you know and on the smaller one just seems to be like guidelines on how do I guess clean it I mean that's kind of odd so to speak I mean it's like paint by number well if anybody has any input please let me know thanks again for the joint I'll try not to add so many pictures next time -
When I found this fossil, it was kind of a big, oblong, sparkling rock. I ran cold water over it and noticed that it started losing some of its size. Needless to say, this is what I have. I had to use my phone's camera so this is the best I can do with the pics. To me it looks like he is trying to swallow something.

I found this fossil on my property at top of Laurelas Grade in Hidden Hills off Carmel Valley Rd. state of Calif. It appears to be some kind of fish. Can anyone give any more information on what this could be? Entire size of rock is approx 6" wide. I have found lots of mollusk type fossils but never a fish. thanks kathleen

Hello from an Ozark Quarry needing advice on Ancient Ripple Marks.
OzarkQuarry posted a topic in Member Introductions
Hello~ I am excited to be part of this forum. Thank you! My husband and I have sandstone bluffs on our property in SE Missouri that he hand-cuts boulders into slabs and wall stone. In this process, he has uncovered some beautiful ripple mark stones. We do not yet have a market for these fossils and often they end up going out on pallets of stone. I have started to take pictures of these individual pieces and was hoping for guidance on marketing and pricing. I have been searching and I can't find any information on how to price these or even what to call them (I tried naming my pictures-hopefully this is correct). I've looked on different fossil websites and I don't see them for sale. There seems to be plenty of blogs that mention these and I was able to find this forum with FossilNerd posting. I will follow up there next! Any help is really appreciated. Thank you~- 1 reply

Found this about 10’-12’ deep while digging a soil sample in Rancho Palos Verdes, CA. I’m located on the peninsula, 575 feet above sea level. Object weighs 2.5 lbs and is pretty solid. Noticed a very small shell imprint. Ignore dark colors, it was damp from cleaning. any ideas on what it might be?

I found this rock in the middle of ARIZONA, Gila County, USA. I've found thousands of fossils in Central Arizona & have identified most, but not sure on some of them, this being one;) It weighs in at approximately 135 lbs or just over 61 Kilos & my back's still feeling that one. Thanks, Joshua

Hi everyone, I'm Roger. I need some advices to proceed with the preparation of vertebrate material from Cretaceous marine sandstones of the Parras Basin in northeastern Mexico. I have some isolated mosasaurid centra with adhered matrix (mainly sandstone, as well shale) and some tiny shark teeth embedded in sandstone. I seek to use chemical methods. I have heard of the use of dimethyl sulfoxide but have never actually used it, if anyone has experience with this reagent I would love to hear your feedback. I am not opposed to working with mechanical methods, but I do not have the necessary tools, in Mexico that market is somewhat limited and expensive, because it must be imported. Any comments are welcome, thanks in advance!

Today, I found one small piece of fossil-like thing in a sandstone rock. I found it in a valley, where there is one small river with rocks which contain many brachiopods, coral, favosites fossils. But this one is different, it is in one piece of soft sandstone rock, others are in harder rocks. Western boarder of the great basin of Sichuan, China. petal_20221129_222903.mp4

From the album: Permian
Some of the famous Texas "red beds" deposited during the Early Permian in streams and rivers, seen near Seymour, TX (member of the Clear Fork Group). Iron in the sand oxidized, giving the stones their eponymous color.-

This ‘fossil’ was found on a river gravel bar in Southern Minnesota. Sedimentary layers in the area include Wisconsin lobe glacial till and cretaceous mudstone/sandstone. The centre of this specimen seems to be just sedimentary material that is slightly harder than the surrounding material filling the core. The outer shell seems to be rock. I am totally stumped. eems to be rock. I am totally stumped.

Hi I found this petrified log of some sort in a sandstone cliff near Inverness Cape Breton Island and am wondering if anyone here knows what it would have been interesting looking pattern around the outside its how I would imagine the bark of a giant fern/ palm tree trunk would have looked long ago , also does anyone know how I could clean it up and bring out more of the bark like texture without damaging the fossil?

My father pointed this possible trackway on a sandstone paving stone on his front walk. I don't know the source of the rock. It looks clearer in person than on the images. There are several possible tracks in sequence- I took a picture of the only one that looks mostly complete (last image, with quarter). Other pavers in the path have odd marks that look sort of like drag marks from vegetation, bubbles, or worm or crab tracks. (not pictured on this post). What do you all think?

If this topic was posted in the wrong place feel free to pull out the whips and chains. These are being found at deposit of petrified wood in south Alabama. Silicification strata sure looks favorable in situ-clay, then 1 foot of wet sand and rounded quartzite, then the wood. No limb nots, most of it has straight parallel bands like a vascular plant. Occasionally some samples with annual rings. Complete logs are rare, most are segments from 5 to 50 pounds. It seems related to Tallahatta silicified sand(stone). And it seems to have silicified grey sand in it. Thanks in advance.

Hello everyone, I am currently staying at the Mountain Lake Biological Station in Giles County Virginia doing research on evolution (on living animals not fossils) and yesterday I decided to take a walk around mountain lake. This lake and the hotel next to it was actually the location that the movie Dirty Dancing was filmed in but due to natural geological processes the lake is now almost completely drained. This draining has revealed a lot of the sandstone and limestone that once made up the lake bed. I was not going here looking for fossils but when I sat down to rest I saw the Pygidium of a trilobite! I am pretty sure that this trilobite is probably of Silurian age but could also be from the Ordovician. I am not sure if its genus can be identified but I thought it was a cool find nonetheless and worth sharing. I will be returning to the bank to see if I find anything else and will post them in this thread if I do.

Found this piece associated with weathering bone chunks embedded in sandstone. My first thought was nose horn but the horn portion looks like it might be a sandstone cast of the inside of the horn. Location Glendive montana, hell creek. What do you guys think?

I have read the bits here and elsewhere about DMSO. I'm not that serious and I'm not sure that's what I'd want anyway. Being new and my first post, I hope it's in the right place. I have some sandstone which was a big clump. Fairly beat up from being in Lake Michigan. I looked and decided to crack it open and see what's inside. Now I have a few pieces and I see some interesting fossils, but they look like the same material, nearly, as the surrounding sandstone. I can only guess that if I try to dissolve the sandstone, I'll probably also dissolve the fossils? These look like shells or outer shells of assorted ancient sea life. With a smaller chunk, I've been putting it into a campfire burner two nights after the fire is going down. I figured heat cracked rocks from archaeology why not try some baked sandstone? Here's a before which hopefully will show what I have. I have some tools, chisels, and a couple of old dental picks. I'm not sure if that's the right way to go. And I wonder if some solvent, over a period of time, sitting out in the garage, might work on the sandstone? Again the acid idea doesn't seem like a good one, whether it's Hydrochloric acid or acetic or something else, the fossils seem like the material is too similar and I'll just end up with a bucket of mush? Anyone with some experience have a starting point to share? Thanks

Can someone please help me identify this. I don't know how old it is. I found this in Rockford Illinois, I found this in a roadcut. A fossil I found near it lived in the Ordovician period.

VIDEO: Ethiopian Amber ("Tertiary Sediments", 23-16 Ma)
Barrelcactusaddict posted a gallery image in Member Collections
From the album: Fossil Amber and Copal: Worldwide Localities
Ethiopian Amber Wenchit River Valley North Shewa Zone, Amhara Region, Ethiopia “Tertiary Sediments” (23-16 Ma) Lighting: 140lm LED Longwave UV (365nm) Specimens: Spec. A (Marcasite): 11.2g / 27x20x31mm (in image) Spec. B (Large Yellow): 8.0g / 41x30x20mm Spec. C (Flow Lines): 8.4g / 34x31x20mm Spec. D (Run [Large Half]): 5.3g / 24x21x17mm Spec. E (Run [Small Half]): 2.8g / 23x19x14mm Spec. F (Green Flow): 5.7g / 26x25x20mm Spec. G (Green Angular): 3.1g / 27x20x15mm Spec. H (Umber [Large Half]): 3.3g / 26x18x17mm Spec. I (Umber [Small Half]): 2.2g / 22x12x12mm *With the exception of Specimens D and E, all present slight matrix on the exterior, consisting primarily of siltstone. Specimen A has a large cluster of iron sulfide mineral concretions on its rear side, accounting for the majority of the piece's weight. Mining, Properties: While there are several other amber and copal deposits on the African continent, Ethiopian amber deposits discovered back in 2010 have proven to be the most productive: on average, at least 20kg is mined by the locals every year. The amber is hard, and ranges in color from dark brown, red, and yellow, as well as varying shades of green; the green coloration is a natural base color, although a green fluorescence can be seen in some Ethiopian material when exposed to high-intensity LED light or sunlight: similar green fluorescent response is seen in some Dominican, Mexican, and Myanmar ambers. The green base coloration seen in some Ethiopian amber was likely caused by significant pressure and heat: volcanic layers of basalt of varying thickness overlie and underlie the deposits, and acted as a natural autoclave. The size of recovered amber specimens ranges anywhere from 5-25cm in size. Geology and Age of Deposits: Amber is found in sandstone and siltstone layers along the valley walls of the Wenchit, Jemma, and Mugher rivers; the amber-bearing layers were originally attributed to the Debre Libanos Sandstone, a Cretaceous geological Formation within the Blue Nile Basin 200-500m thick: this assignment was based on local observations, a geological map, and fossil spore identification. However, due to incorrectly-dated and some then-unidentified fossil spores, as well as arthropod and plant inclusions from genera with living relatives, the amber is believed to be Early Miocene in age. The amber occurs not in the Debre Libanos Sandstone, but in Tertiary sediments comprised of siltstone and sandstone situated between basalt layers, which often display columnar jointing. These basalt flows vary in age from Early Oligocene (~30 Ma) to Quaternary (2.58 Ma to Recent). Inclusions, Botanical Source: Ethiopian amber is frequently rich in inclusions, especially bacteria and fungal spores; plant inclusions include liverworts, various angiosperms, and rare examples of mosses and lichens; arthropods are abundant, including mites, spiders, and over 13 families of hexapods (e.g., beetles, flies, ants, etc.). Comparing the spectrographic results of Ethiopian amber with Dominican and Mexican ambers, has shown that this is a Class Ic resin, most likely produced by a member of the Fabaceae family; fossil leaves and flower parts of trees belonging to the Hymenaea genus have been found in this amber, adding weight to the chemical analysis’ findings.
