The purpose of this general is to encourage people to go /out/ and find cool fossils and artifacts. This thread is also a place to share our own collections and things we find when we are /out/ hunting.

Rules are as follows,
>To just post and discuss fossils and other related geological subjects.
>When you post about a fossil in your collection, please label it with what formation it is from, what it is, and where in the world it is from.
>If you don't know where it originated or the species that is ok, just label it as so
>You can post rocks and minerals as long a they are ones that you have found while /out/

Sorry for the lack of a post/new thread, Life has been far too hectic to keep up with this thread on the past few months and my last trip fossil hunting was last November. Pic related is a segment of fish spines that have feeding traces on them. I should hopefully be making another trip up to the Dallas area to do some more hunting soon.

You always gotta wonder what happened when you see stuff like that

>>2812196 (OP)
I did some work as a construction materials testing tech and got to go to some nice middle of nowhere places in S/SE new york and I'd find cool rocks every now and again on nature preserves in the upturned piles of earth

>>2812868

>>2812869
Found this while doing soil density testing at the catskills watershelf facility

>>2812869
Found this one at the Ashokan resevoir on a bridge job

>>2812196 (OP)
Oh wow, a prehistoric Kit-Kat such a nice find OP.

Nice Metamorphic rocks anon

More fish fossils this time around. Here's what looks to be a section of vertebra and tail fin of a nice sized fish but there's too little to tell what species it is from for me to say what fish it belongs too. Britton Formation, Eagle Ford Group, Denton Co. Texas

Dinosaur anon reporting in, the season has started and Im doing a multi day in the oldman formation this weekend. These daspletosaurus teeth are from last weekend.

>>2815795
what's the process for determining what species those teeth came from?

>>2815819
not him but it's usually a matter of knowing what animals have been found in the formation and then going by size. In the oldman formation there's only one theropod dinosaur of that size.

You can also tell that the teeth belong to a tyrannosaurid by their thickness and shape, but that's just a matter of looking at lots of different dinosaur teeth to learn.

Montana rock hound here. Looking to find a general rock identification book. There a couple on Amazon but I'm wondering if you guys had any recommendations? Colored pages are a plus, with detailed explanations. Don't need locations just how to id. Thanks guys.

>>2812196 (OP)
What kind of rock is this?

>>2817175
looks like meteorite or lava. Is it magnetic?

I wish we had cool shit or go find out in the outback.

t.Australian

>>2817199
Not magnetic, heavy as heck to comparable rocks its size.

>>2817239
"Heck"

Honest to God, fucking kys your fucking bitch made homosexual zoomer.

>>2817322
Youre on one dude, we said heck in the 90s.

>>2817239
inconclusive then. I'd take it to an expert at a rock shop or museum. Might be a meteorite but I can't rule out lava if it's not magnetic.

>>2817175
Hard to say without breaking off a chunk to see unweathered surfaces. It could be a pyrite or hematite nodule. Or depending on where you found it there's a very good chance it's a big chunk of smelter slag that has been bouncing around in a river for the last hundred years.

AI says its petrified wood

>starts fossils and artefacts general
>doesn't call it /fag/
Are you fags even trying?

is this part of an arrow head? i genuinely can't tell.

it was out in the middle of a prairie with no other rocks around it for several hundreds of feet.

>>2817679
not a great pic but it doesn't appear to be worked. The flakes are very worn and random, and most of them don't break the rind. My guess would be natural.
The bottom edge is shaped like a thumb scraper, but again doesn't appear to be worked. A better focused pic would give more info, but it doesn't look like an artifact to me.

>>2817330
No, if you were trying to be funny you'd say H. E. DOUBLE HOCKEY STICKS. you on the other hand are a faggot and a larping zoomer.

>>2817949
he's right
heck is a GenXism
holy heckterines is another one from that age so long ago. Watch Napoleon Dynamite, it breaks down the 1980's and 90's white boy vernacular quite accurately

"decroded piece of crap" is my favorite genX phrase.

>>2817949
Not wanting to swear is a sign of maturity, youre letting politics or whatever zoomer stuff live in your head rent free and effect your day to day engagement online. Chill bro.

Anyone know what this is yet?

>>2818565
Vesicular basalt.

>>2818565
Crack it open.

>>2818578
don't do this, it releases mustard gas.

found this sitting right in the middle of a trail. Is this an omarolluk or a nutting stone?

My bet is on an omar because I live in a glacial area and it makes more sense to be sitting in the middle of a trail with decent foot traffic, but I realize that I don't really know how to tell the difference between the two. How does one tell?

Nice little quartz cluster I found on my walk today. One even shows some twining

What think are beryl in schist along with a little bit of hornblende

Found this close to naturally occurring amethyst and quartz, any idea what it might be?
Sorry for the bad quality image.

No idea what this one could be.
It was covered in red rust when I found it, so I left it marinating in sulfuric acid for the night. Before, it looked almost golden under the crust, but now it's clearly metallic grey.
It's also very dense and heavy, more so than iron by my rough estimate. Also, it's non-magnetic.

Maybe a more educated anon would know more. I'm completely clueless about geology.

>>2820498
If it was rusting and it's not magnetic then it's a random piece of corroded steel or hematite. Try to draw with it on a hard surface, if it leaves behind a red streak then it's hematite

>>2820498
iron pyrite, specifically marcasite.

>>2820638
>>2820675
My hiking buddy was convinced it was a meteorite kek
But yeah, most likely it's just marcasite. Thank ye kindly for the prompt responses.

>>2820679
it's a cool piece. Nice find

New to this. Found this piece of pottery or something in a field, east coast USA. Anyone got an idea of what it could be?

>>2821469
Back

>>2821469
Looks like a piece of pottery

>>2821469
whiskey jug, late 1800's- early 1900's

My collection of fossilized shark teeth found on a Florida beach on the Gulf of America.

some gold from old mines in colorado

>>2823699

>>2823699
Shit man I wand gold too

>>2823706
I've collected quite a lot of it over the years.

>>2823709

>>2823709
Almost enough for a pizza

>>2823717
a very expensive pizza. Or a couple hundred dominos two toppings.

>>2815795
some awesome teeth anon, I'll be continuing my college education in Kassas starting in august, I'll need to make a trip to the Dakotas to check out the Hell Creek Fm and see if I can't get my hands on some Theropod teeth.
>>2817230
Not sure where in Aus you live but theres a guy on Instagram that does a lot of hunting there his user is @trav_fossils, Hope this helps
>>2823060
Nice Collection of teeth, more than I've ever found on the beach
>>2823699
I'd love to have a chunk of quartz with raw gold in it myself, what part of Co are you from?

Here's an interesting find from the backlog of photos, some type of lobster or shrimp in a concretion that looks to be fully intact with its claw. Unknow sp, Britton Fm, Eagle Ford group, Denton Co. Texas

>>2825403
Thank you! I found them, on Venice Beach Florida.

Thoughts on this? It looks like something but I'm not sure what it could be.

>>2825712
I'm not particularly sure, possibly a banded sandstone
>>2825403
Here's another find form the same site, this is more than one fossil. Some type of burrow, probably lobster, that has fish cales and ammonites in it. Britton Formation, Eagle Ford group, Denton Co. Texas

>>2817679
The material on top looks good for knapping and there's a couple flake scar ridges, so this might be a primary flake (a product of taking the cortex off a rock). But the picture isn't great so it's very tough to tell.

>>2818763
Have you tried nutting in it?

>>2829093
thought about it

>>2818763
too big to be a nutting stone
