I found this fossil (?) clam shell on the trail while I was taking a break from Muni. I happened to look down on the ground and saw it among some rocks and dirt.
I think the top brown part is the actual shell, and the tan part is the mud that seeped into the clam after it died, and formed rock when it hardened.
Ooh, good find. It’s relatively intact.
I love finding little things like that when I’m outside. I found a perfectly intact skull while out rabbit hunting once, I boiled and sun-bleached it and it’s been sitting on the top of my dresser for like 2 years. 
We think it’s a dog skull, maybe a coyote.
Very nice.
That’s a great fossil! Do you remember where you were? Since Texas hasn’t been glaciated, the fossil bed it came from is probably close , so you can probably find more fossils near by! Check it out!!!
If you take it to the local college, they may be able to tell you about the organism. Or there my be a paleontology forum where you could post a pic and find out if you’re interested.
Nice clam. I used to find all sorts of fossilized crustaceans along our dirt road, but they paved the road a few years ago, and now all I find are skeletons of frogs, raccoons, boars, and snakes that my cats kill.
Cats killing a boar? What kind of cats do you have!?!
Just an Abominable Tabby and a Saber-toothed Elephantiger 
Yeah, turns out these shells are pretty common. You can actually buy them for around $5/each! Still I was happy to find it.
is this a fossil?
Being that that style of unicycling hasn’t been around long, I would conclude that the guy is not a fossil yet.
yay I´m no fossil
