Hi All! Whilst in southern Spain I came across these three very interesting fossils (at least I know one of them is) please could you help identify the other two? #1 This shell like fossil was full of rock, which I managed to remove without damaging the shell. #2 I'm not so sure about this one, it has some interesting mineral going through it and the markings which looks like an arrow with a circle at the base are what caught my eye. #3 And the ammonite, correct me if this is wrong. Thanks in advance for any help that can be given 😁

Found this amongst other critters in the Upper Glen Rose near Spring Branch, TX. I'm at a loss, but I'm thinking it's a worm. Also, I'm not a worm guy. Clues, hints, full-blown answers, and red herrings appreciated. :-)

Good Day, I currently reside in Houston but have roots in West Texas and the Hill Country. Having been away in the intermountain west for the last 23 years, getting back to limestone is a joy! I've been a fossil collector most of my walking life and enjoy thinking about what must have been here and Wow, it is just mind boggling to consider! Rocks and minerals, geology and the world we live in is fascinating from so many perspectives. I'm an environmental scientist by trade and currently work in the transportation sector.

Can anyone tell me? Looks like crinoline to me.

The limestone in Central Texas erodes in such strange ways. I was walking around behind my house after Tuesday’s rain and found this real oddball. I’m pretty sure this is non-biological, but it’s still really neat!

Blair County, Pennsyvlania USA From roadside rubble outside an area quarry in the Keyser/Tonoloway, which is known to have karst features OK, so this isn't a fossil, but it caught my eye while fossil hunting, and I learned something so thought I'd share. One side of this limestone slab has a ton of pebbles glued to it with some sort of mineral layer, with the rough look of partially dried up butterscotch pudding (that's a technical term, right?). I don't see any fossils in this slab. The limestone fizzes, the glue layer does not. Just guessing, it looks like maybe there was at least a crack if not a larger passageway, debris from the "ceiling" accumulated, and later the mineral glue was deposited to glue them in place. Part of me wonders if this might be from the anthropocene, with quarry blasting shaking bits from above and then the mineral glue came along.... or maybe all these pieces were placed loose in a heap, and then the mineral glue came along.... Anyway, is there a technical term for this rock type? While prepping this post, I started wondering if stalagmites are sedimentary rocks, and then found this pretty basic info which explains that sedimentary rocks are divided between clastic sedimentary and chemical sedimentary. I kinda knew that intuitively but never really thought about it or knew the terms. Beyond me sharing my Aha! moment on something so basic, does anyone have a more precise technical term for this slab? Any opinion if if this shows all natural processes (before I came along that is!)

Good afternoon, I found this tooth today digging in a rockshelter near lake Travis. The tooth was found amongst other deer and bison bones about a foot deep. I've read Texas rockshelters in this area house animal remains from roughly 25,000 years ago.

Found this in a central Texas cave and was hoping for a possible ID

I found this odd bone wedged in a crevice as I was descending down the depression. This was found in Travis county
