it looks like dolomite to me, what's the hardness, around 4?

those ammonites could also be planispiral coiling gastropods, or goniatites (ancestors of the ammonites). Ammonites don't usually have such a tight coiling rate. I would most likely call it a gastropod, especially considering the likely Paleozoic age of the rock; they are quite common in Ordovician - Silurian sediments. The shell is either a pelecypod (clam) or brachiopod, can't tell for sure since one wing is buried in the rock.

from what I can see, the cross sections are mostly pelecypods, plus a few gastropods. No brachiopods there. There's a few sites where you can get stuff like this, but I haven't seen any from TX. Nice looking.

Spectrolite is a gem form of labradorite. Hardness 6. Like spectrolite (and incidentally, all feldspars) if you orient the rough before slabbing, and have large crystals to saw, every slab will have the fire face oriented. I used to orient and slab big Brazilian amazonite crystals for cabbing when I could get them about 20 years ago. They would have a silver sheen in the sea green. Wish I could get those again....

that round white rocks aren't echinoids. I research that group of fossils, and to me it looks like a chunk of howlite. Nice stash

those red jasper berries remind me of the Waco Jasper. Are there parallel bands in it spaced out about 3/4 inch, with perpendicular lines in it?

no surprise there. eBay's corporate attitude was one of the reasons that it chased me off.

I just ordered from Shawn Tuesday night. Friday my parcel arrives, and there's candy in it too. I just wish the stuff that had been drop shipped would show up that fast. (expando drum for cab unit).

when I'm on the road, I bring my cabbing unit along, and often prop it up in the motel bathroom I think that's not so good of a sign

let's see, what sort of ammonite do you want? I have hundreds of them from all over the world. Any particular species, preservation, size, locality, etc?

it might not be completely petrified. I've seen that several times, but it's not really common.

well isn't that a small world! I very much dislike Dallas, the club members are mostly rude and can't handle a fossilman like myself that tends to find all the fossils they missed wandering around I really hated it when I would set up at shows and they wouldn't buy a dang thing but would spend what seemed like hours copying down fossil ID labels so they could go hunt them by thenselves.

I used to buy rough with Mac years ago.
Turns out, according to the lawyer, I need to move back to Dallas during my upcoming divorce. Major bummer.
The Arlington ammonite sites are pretty much played out. I haven't collected them in a good 10 years, too many locals know abotu them.

I know about all the clubs there, I used to be a member in them in the 80's and 90's. I know the Austin area well, I grew up rockhounding here, and could show you a few areas that the city hasn't shut off the collecting in. But Bastrop is new territory to me, I hunted north and west.

Ok, I finally have a new home, I've returned to Austin, where I grew up. Any members down this way that are looking for collecting partners? I hate going out alone, though I've become used to it since the soon to be ex HATED rocks - if I only knew before we got hitched...

when I was a kid, I found a bunch of massive pyrite and molybdenite inside a bunch of used oil drums at an abandoned factory in Pittsburgh near my grandmother's nursing home. That was in the days when the steel industry was still going big there.
