This is a tusk I prepped a few years ago, sourced from central Alaska. It was in great shape for being a partial, no breaks to repair or even major cracks to fill, all natural besides a little stabilization and polishing to bring out the colors. Really strong vivianite on this one and inside the internal cavity appears to be crystals. It was tricky to get a good photo of them, but see below. I took a few of the inside shots with a UV flashlight as well as just a flash. Vivianite crystals?

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

This just fell into my lap, but I'm having a hard time telling exactly what it is. Seems to have been burrowed in by clams? Worms? Somethingorother. Not my area of expertise, so I rely on y'all. Found in northwestern Natchitoches Parish, Louisiana. Sorry for the lack of scale, but I assure you, those are standard-sized human hands. First four photos are outside, last one is a straight-through cut. Any ideas? Appreciate the help as always!

starting to look for Micro fossils in the Pittsburg Bluff Formation - what is this?
OregonFossil posted a topic in Micro-paleontology
I've looked at a lot of sediment now and I just found this. It is a perfect sphere and semi-clear. Hard but perfectly round. Don't think it's a microfossil, but anyone have a guess as to what it is? It was inside a 3 x 6" piece of the formation. Image about 4-500X. Object cannot be seen with naked eye. -
Even though I fancy myself as a self-collector of fossils, I have always been interested and attended shows as they are excellent learning/networking venues. For the past few years, I have been attending the Quartzsite shows. The first times I attended, I was pretty lost since they are actually a series of shows, some overlapping, some not, at different venues. Very confusing. That's part of the charm though since there is much to like about these shows: they occur at a time of the year (winter) when nothing else is happening in much of the country, you can find excellent bargains, they are pr

Denver Mineral, Fossil Gem & Jewelry Show 2021
Top Trilo posted a topic in General Fossil Discussion
Yesterday (9-11-2021) I went to the Denver fossil show. It was my first time going and I really enjoyed it. Most of the show was minerals and gems and jewelry however there were quite a few fossils. Unfortunately, most were Moroccan. There were some Pleistocene fossils, Meg teeth, USA Dino material and a few other things. Well might as well start with the photos. Let’s start with the few mineral pictures i took. Next up the Moroccan material which dominated the fossils present. -
Are these "black rocks" fossils, pumice, slag? I'm so confused
natwell19 posted a topic in Fossil ID
hello all, I found a lot of this specific type of rock and I thought they could be fossils. Now I'm not so sure. They have what appears to have a spongy inside and flat outside, on the sides that are still there. I tried to take pictures to show them well. A few of the pieces have two "lobes" at one end and the lobes appear to be splitting. They are all the same color, though some are dry and some are damp still. I was trying to figure this out on my own, and I thought it could possibly be coal (if not a fossil), but i really don't know how to test it. My husband did try to light i -
What do you think. Found in James river. Central Virginia

Hi guys, I recently started learning to fossil hunt for my son as he loves dinosaurs and on our first trip we found this in a limestone. I am completely new and really sorry if this borders on an insult to some of your experience but I have no idea whether to crack the rock open and have a look or whether I’d end up breaking a fossil of some kind if I did or whether it is just a mineral running through of some sort! There was a much larger rock with the same streaks but in a diamond shape on the beach so if it is a fossil I’ll be running back there ASAP Tha

These were all found in the same river, over time. It is a river in SE Texas known for fossil finds from large mammals in the Pleistocene. I think due to their river tumbling they are not identifiable, but I just wanted to see if it is possible they could be some type on mineral rather than bones? Pics are front back. We find a lot of petrified wood in the area too, but it normally looks distinct from this. The two on the left almost look like they are variations of the same thing, and the one second from left has some kind of almost enamelish looking stuff in threads on the surface. Non

Are these fossil shells with odd mineralization or a mineral of some sort?
-
I was wondering if someone knows if this is a fossil. Since it might just be a mineral? Anyway it weights 1 kg so its heavy, and also found in the Philippines. Any guess or answer is appreciated

Looking to try a new twist to the blind trade. I propose a blind trade for one item only. It can be a fossil or a mineral. Is anybody out there interested? I only ask no junk/ scraps. One decent item for another.

San Antonio, Tx This one had an odd coloring and texture. Looks like shell and sediment.

I made this a few years ago and I'm not sure if I shared it with the group or not. Its something I came up with and thought it would be cool to frame and hang near my desk. Its not fancy and the verbiage might not be precise but I think you get the Idea Besides fossils, I collect specimen grade seashells, minerals, skulls, and artifacts (I include artifacts into Natural History). I made/printed one off for each collection. Happy Collecting!

I have been finding a lot of these recently. They are waxy to the touch and come in a variety of pale white to orange tinted. Are these pieces of amber or are they some other kind of mineral? Thanks!

What percent of original material is actually preserved in fossils?
Somethingwicked posted a topic in General Fossil Discussion
So, I know fossils are largely replaced by minerals which turn them to stone in the shape of the original (bone, tooth, whatever). But do some minerals survive? For instance, does the original calcium in the tooth or bone remain? What percent of a fossil would you guess is original mineral vs replaced mineral? -
Hi all, I was wondering if anyone was going to the NJ gem, mineral, and fossil show... I’m considering going, but I wouldn’t be super interested if there aren’t many fossil dealers, I was also wondering if anyone knows how many dealers are going to be there. TIA!

Found this in the same location I found the shell fossils in my previous ID post.

Is anyone going to the Denver mineral and fossil show?
thelivingdead531 posted a topic in General Fossil Discussion
Hey everyone! Is anyone going to attend the Denver Mineral and Fossil show this September? It runs from 11-19 September. Now that I live relatively close I want to try to go this year. I would like to meet any of you amazing people if possible there. -
Found in Jackson County Missouri (I didn't find it myself, but I can most likely get more info on location it was found.) I do believe it was found in a dirt road alley. Long dark grey and brown striations, that cannot be scratched with my nail. Then on one side in a few large chunks, an orange/brown (rust colored) residue, that can be scratched off. I thought my pictures were going to look much better than this. So I can get better pictures ASAP if need be. Let me know any other information I need to provide. Thank you for looking! Hope everyone is

Hello, I've been intrigued by this for days, and I am wondering if it is a fossil or not? Found in Northamptonshire, UK, which is mostly Jurassic in age. I've found Bivalves, belemnites and some gastropods in the same area. Sorry there's no scale, its about 5mm. Thanks.

Hi all, I found this in a stream in Eureka, MO, USA. If anyone can help me with identifying, please do!
