This is a small piece of Turritella Agate from Wyoming. It's full of fossil shells. While this type of material was named years ago after marine fossils, the actual type of fossil was called 'Elimia tenera' according to geology.com. But it is wonderful material for cutting cabochons for jewelry or display. There was a blue pencil mark on one side, mostly erased but should polish off. It measures about 2" x 1 3/4" (not including where it juts out) x 5.8 mm thick. It weighs 37 grams or 1.3 ounces. Ready to be cut and polished into a special jewelry creation. (First Class shipping for less is available on request.)

This slab is a slice of sedimentary rock, a limestone 'Pisolite' (also called an 'Oolite'). According to Dictionary.com, an 'Oolite' is any sedimentary rock, esp limestone, consisting of tiny spherical concentric grains within a fine matrix (from French - 'egg stone'). They are usually up to 2 millimeters in size. When the little egg-like formations are larger than 2 mm, like we see in this material, they are called 'pisolites' (relating to pea size). I have seen these called fossils, but I found data arguing that Pisolites are actually not fossils - we will leave that to the fossil experts; fossil or not, this one is a neat slice of this stone. The material is found in the Bristlecone Pines Forest Reserve area in Bishop, California, so can no longer be collected; thus our understanding is that it is rare. It looks like a nice solid piece, great for cabochons or a display specimen (unpolished as it is, or polished). It is about 3 1/2" x 2" x 5 mm thick, and weight is 57 grams or 2 ounces.

This slab is a slice of Dinosaur Dung, called 'Coprolite' (coprolite comes from two Greek words that basically mean 'dung' and 'stone'). You can see by the photos that it has a number of fractures, so doubtful the buyer could get anything by a few small cabs of out this one; carefully polishing it as a display would probably be ok. But very neat piece unpolished as it is. It measures 4 1/4" x 2 1/4" x just over 6 mm thick, and weighs 81 grams or 2.8 ounces.
