Been a bit since I posted anything, but now's the time. A few years ago, I bought some shale from U-Dig fossils & have played around with it here & there since then. Ended up with some odd shaped pieces and several tiny little trilobite bits, but nothing major. Earlier this morning I was poking around at one of the odd shaped pieces & noticed a partial circle shape sticking out. Viewing with a jewelers loupe I noticed a crack next to it that ran over the top so I started trying to widen it. Suddenly I heard a click & the top section popped up a bit. When I removed it, I found both the positive & negative of a full trilobite (just slightly disarticulated). Measuring 3 cm long by 1.75 cm wide. Used my dino-lite for the pics, but had to turn off the built in led's & use an led flashlight at a angle to do it properly. It's close to the same hue as the shale at this point. 1st pic is the positive & 2nd is the negative imprint. Not sure what species it is & wish the pics were clearer, but I don't want to try cleaning it for fear of ruining it.

Accomplishing the impossible means only that the boss will add it to your regular duties.

Both? There's only one there, just a positive & negative impression image. :ironic:

But thanks for the I.D
