Hey check out this petrified log.





80+ cm tall and probably about 1000 lbs. It hasn't budged from this spot in the 5 or so years I've known about it and I don't imagine it'll be moving any time soon. It's deep down a rough, limited access road & halfway down the side of a particularly steep hill on extremely loose, sandy soil. I'd love to know what species of extinct tree this used to be.

I spend a lot of time working in the area surrounding two relatively popular rockhounding sites and have been picking up neat looking stones for years. I recently met someone who's an avid rockhounder who has taught me that I have agate, jasper and opal coming out my rear end.

Also a biologist by trade, and I watch this clip at least 3 times every time I visit this thread and it doesn't get old or less relatable. I've had avid rockhounds on my crew that I inevitably embarrass myself in front of. I have no idea if this is jasper but yes I did collect 3 buckets full. I thought this was agate? What do you mean calcite? I filled my whole truck bed with it!

Now that all the rockhounders have left for greener pastures grad school months ago I am still regularly finding rocks in every vehicle/around the lab/in every equipment storage area/in my loving apartment somehow. It's like a disease.

Wanna see the saddest thing you've ever witnessed in your life?

I hauled this massive stone 1.5km and about 300m up a mountain, it weighs about 25lbs and is 24cm in length. Home free, about 2 meters from the UTV, I had to cross a pasture fence and wanted use of my hands to not nick my new pants so I dropped the rock on the other side of the fence without thinking, and now I have three rocks where once I only had one.

Prepare to cry, i sure did



Anyone have a clue what this might be?

Oh boy, it ain't boring.


All photos of the break surface are oriented with the fossil imprint facing upward.



I cleaned it up a bit and got some better photos, here's an album: https://imgur.com/a/zfm84mz

I'm pretty curious what those black dendritic markings are. I borrowed a book on fossils from the library and I've been seeing a lot of similar markings on photos of ammonite fossils but I'm still leaning toward the larger fossil being something in the plant kingdom, though I could also see it being crustaceans or a trilobite of some sort.

For more context, I found it in the Bilk Creek Mountains in NW Nevada at about 6000' elevation. The rock is somewhat brittle with fragments chipping away if I don't handle it gingerly enough. Here's a pretty unhelpful video from the approx. location it was found
