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!

I was wondering if anyone knew any good places to hunt fossils or rocks in Minnesota where I live or Wisconsin

I found this fossil / mineral over at Folkestone, and would really appreciate any help in identifying it. It looks like it could be part of a larger organism, but also appears rather crystalline in shape. Does anyone have any ideas on this?
-
The bite mark(lol I know it’s not a bitemark) is an inch long and ONLY that part has crystalline chips in it. Any help would be appreciated.

From the album: Fossil Flourescence
I was playing around with the UV lamp in my lab, seeing what might unexpectedly glow this afternoon. This was a nice surprise. It's an internal mold of Bacculites sp. with sutures that fluoresce orange under 345nm UV light. Bright orange like this usually indicates calcite, a mineral that makes up fossil shells and some modern ones, too. Between the mud-filled chambers, the shell was preserved while the exterior of the cone wore away. The shell material was either calcite to begin with or, more likely, began as aragonite (same chemical compound as calcite, but different crystal structure and g© C. 2020 Heather J M Siple

I tough these two "things" were coprolites (cut and polished), but after taking a look at past discussions here I'm no longer sure. On other other hand, I don't know of minerals that would grow on a spiral. What do you think? Diameter is about 10cm and 5cm, respectively. No idea about provenance - both bought at flea markets in Germany. Thanks in advance
