daves64 Posted February 23, 2019 Share Posted February 23, 2019 I recently got an "enhanced grab bag" of fossil matrix. The matrix is from NC, the enhanced portion is shark teeth added in from SC & FL. This large chunk of something was in with it. At first I thought a nice big bone piece, after cleaning it up, not sure if it's bone or some sort of mineral deposit. Pics 1 $ 2 are of the sides, 3 is the narrow "top" & 4 is the split bottom section. The remaining pics will follow. It was just under 17 cm long until I cut about 2 cm or so off the narrow end, 3.5 cm wide & 4.5 cm thick. In the split section & 1 end there are several small crystals embedded in the openings. Red, green, yellow, clear. I can take pics of some of them if needed. 1 Accomplishing the impossible means only that the boss will add it to your regular duties.

daves64 Posted February 23, 2019 Author Share Posted February 23, 2019 Pics 5 & 6 are the ends. 5 is where I cut & sanded it to try to get a better idea of what I have. 6 shows some of the crystals. 7 is a close up of the split area & 8 is a close up of the outside. 1 Accomplishing the impossible means only that the boss will add it to your regular duties.

daves64 Posted February 23, 2019 Author Share Posted February 23, 2019 The 50, 100 & 200x labeled pics are from the same spot on one of the pieces that broke off while cutting, making it a fresh break. The 200x 2 & 200x 3 are from slightly different spots on the same piece 1 Accomplishing the impossible means only that the boss will add it to your regular duties.

ynot Posted February 23, 2019 Share Posted February 23, 2019 A piece of volcanic rock with micro geodes. If You can get some close up shots of the "geodes" it may be possible to make some IDd of the crystals. 2 Darwin said: " Man sprang from monkeys."

ynot Posted February 23, 2019 Share Posted February 23, 2019 Red pieces are probably garnets. Clear yellowish are maybe calcite (could be quartz).

daves64 Posted February 23, 2019 Author Share Posted February 23, 2019 Found this on the web. Polished volcanic rock with Peridot, maybe that's the green. The rock itself looks like the sanded/polished end of mine. 2 Accomplishing the impossible means only that the boss will add it to your regular duties.

daves64 Posted February 23, 2019 Author Share Posted February 23, 2019 Got one of the clear crystals out of the end & put a drop of vinegar on it. It didn't seem to notice it at all... 0 reaction. So I'm thinking quartz on those. 1 Accomplishing the impossible means only that the boss will add it to your regular duties. Link to comment Share on other sites More sharing options...

daves64 Posted February 23, 2019 Author Share Posted February 23, 2019 Highest magnification I can manage with the Dinolite.. 225x Very touchy focus at that point. Some of the grains looks like pyrite, one area has a rainbow effect, one shot of some other grains & the last pic actually looks a lot like a close up of cloudy amber, which is odd. These are all from piece's I cut off, completely raw, no sanding. All but the last are from the broken part, the last pic is an area that I cut. I cut the thing with a hobby hacksaw (a bit of work). 1 Accomplishing the impossible means only that the boss will add it to your regular duties.

LordTrilobite Posted February 23, 2019 Share Posted February 23, 2019 Can't comment on the minerals, but that's definitely a piece of bone. 1 Olof Moleman AKA Lord Trilobite Link to comment Share on other sites More sharing options...
M Harvey Posted February 23, 2019 Share Posted February 23, 2019 The cell structure is bone. Size and shape suggest a Mosasaur splenial but it is anyone's guess. Without knowing the location and age, it has very little scientific value, but could make some nice jewelry.. 1 Link to comment Share on other sites More sharing options...

daves64 Posted February 24, 2019 Author Share Posted February 24, 2019 Heard back from the seller. I sent a pic of the bone with the email. "The bone in the picture you have below is most likely part of a whale rib bone. I fossil hunt in North Carolina, so the bone is likely Miocene or Pliocene in age. The whale bone I collect comes from a creek in Greenville, North Carolina" So, does that clear things up a bit? 1 Accomplishing the impossible means only that the boss will add it to your regular duties.

That makes sense to me, I went fossil hunting there back in 2017 and found a ton of whale bone similar to yours. Here's what I found after scouting out an entry point to the creek before I even got the sieves out from the truck. Link to comment Share on other sites More sharing options...

Olivine is a very high pressure, high temperature mineral usually in ultramafic lavas from the mantle. If this is olivine, then the piece has to be some kind of lava. In that case, I’d say vesicular lava like this https://duckduckgo.com/?q=vesicular+lava&t=iphone&iax=images&ia=images&iai=http%3A%2F%2Fupload.wikimedia.org%2Fwikipedia%2Fcommons%2Fd%2Fd6%2FVessicularBasalt1.JPG Each dot is 50,000,000 years: Hadean............Archean..............................Proterozoic.......................................Phanerozoic...........

I’m pretty sure the green sand is glauconite. There’s a lot of glauconite and garnet sand in the creek. 1 Link to comment Share on other sites More sharing options...
