If you put enough blubber around it it will float. Jim

Scott: No, far as I know, the whalebone comes from Miocene period sandstones and has been found in situ, though the only examples I've found in the Miocene rocks ( Sharktooth Hill) are permineralized not agatized. No dino bone in rocks of that age ( about 20-22 million years old). I have been curious though, as to whether the agatized whale bone is actually older than Miocene as whales became common in the late Eocene, not all that many millions of years after the dinos ( dino bone maybe 65 million years old, Eocene period about 50 million years ago). I've always wondered exactly where the agatized bone comes from and if they are leftovers from earlier whale species. Rocks that are beach finds are just difficult to date. Funny though, all the brecciated stone canyon type jasper found on the beaches right with the whalebone is Jurassic age stuff.
I have hunted these same Jurassic age cherts on old inland beaches up at Creston, CA but no whalebone in the deposits out there that I've seen. Just another mystery I guess. maybe one of our fossil guys knows more about the agatized bone.....Mel

Ok, so everyone agrees that they do not float but it seems like there would be a big difference between a bone that is holding weight above ground and one that is basically holding the shape of the mammal and muscle attaching points. A lot of strength required but in a different way.
After that went through my mind I got to thinking about the, probably hundreds of thousands of different dino bone structures, and it may be impossible to figure it out without chemical analysis or carbon dating. Jim

I found several piece of this stuff - can't quite put a finger on exactly what it is. Definitely agatized - jasperized but has an appearance that resembles granite in places. This cab is from rough that seems to be the less-pitted of the pieces. Not sure if it's attractive enough to continue to work with it haha. ![](http://aquariagraphics.net/rocks2/IMAG0637.jpg) ![](http://aquariagraphics.net/rocks2/IMAG0635.jpg)

Great shine on an interesting cab. Sure looks to be related to the same material that yields the fluorite mine plume. Folks call the plume there agate but to me a lot of it s more of a plume jasper, as it's opaque. Even the pieces that have more agate in them are not all that transparent but some of the plumes are really well developed so that kind of makes up for it.....Mel

Not to change the subject but, Scott, this is a whale vertebra collected from Shark Tooth Hill in California. ![](http://i907.photobucket.com/albums/ac274/jakesrocks/Dons%20Fossils/101E0251.jpg) Them's some purdy stones Tommy.

A lot of strength required but in a different way. Not, if it's petrified. Then it's all the same specific gravity, no matter what the original use for the bone was.

Hahaha yes she did didn't she? ![:P](//storage.proboards.com/forum/images/smiley/tongue.png) I think that goes both ways though... That was one of the pieces I was finding on the hill right outside the fluorite mine canyon.

Holly molly Garfuncle that one face has the ENTIRE COLOR SPECTRUM. Half a slab of that would be like ten other slabs put together. Your luck runeth over. Jim

Wow Tommy that one's a beauty. More color than I'm used to seeing plus the dots, the red moss and the plume too. Got a little bit of everything in one stone. That one should make some outrageous cabs. Great find!.....Mel

![](http://aquariagraphics.net/rocks2/IMAG0635.jpg) Tommy, that is such a sweet stone!! Great job on it! And this one - ![](http://www.aquariagraphics.net/rocks2/IMAG0659.jpg) This is the one you and Eva got, when we went back up the canyon to pry rocks off the hill? When you said you were going to stay at the car and rest?! This one is off the charts freakin' awesome! Yeah, I think you may be able to do something with that.... I just can't get over the mix of colors and shapes.

If you have a UV light, try it on those. Yellow can be an indicator of radioactivity. Clear areas will almost certainly light up under UV, but the yellow may give you a surprise.

Hahaha don’t think I like them kind of surprises.
I’m getting way far out of my expertise on this but since this was found in close proximity to the fluorite mine what are the chances that the purple is fluorite? I know the most of the fluorite that Jean was finding was transparent crystal form and this is not obviously.

LOL Tommy. I doubt if there would be a dangerous level of radiation present. But just to be on the safe side, you might want to store those outside of your house. If I still lived over there, I'd check them for you. I have cabs of yellow material from the Kramer Hills area that give a very low level reading. Had them for years and I ain't dead yet.
Then again, there may not be any radiation present in your pieces. Other things can cause that beautiful yellow color.

And this rock came from CA? Wow! And what was Scott doing all this time? Where is he now? That stone was 500 yards from the parking area for the entrance to the fluorite mine canyon. It's been there thru 50+ years of intensive rockhounding, just waiting for our friend Tommy to take it. Tommy was a manimal that weekend. The energizer bunny working every nook and cranny. The work paid off in this gorgeous stone ![](http://www.aquariagraphics.net/rocks2/IMAG0659.jpg)
