Cookie Cutter Matrix Curiosities


Recommended Posts

Posted (edited)

Going through the "things" I got out of Jeff's (jcbshark) Cookie Cutter Shark matrix, there are a few items I just don't know about.

First is a little tooth with odd forking crown. Scale is mm.

Second is a group of small shells. I saw recently that someone was selling the same on EBay as fossil shells from "Cookie Cutter matrix". Are these actual fossils or modern shells?

And lastly, there are quite a few of these in the mix. What are they and is it something I should consider collectable (meaning a fossil of some sort)?

Not familiar with the looks of these little guys. All are about 1/4" or smaller.

The small tooth looks like a pinfish tooth, Lagodon sp. Most of the shells are fossil shells, but there are some recent fresh water clam shells mixed in this matrix.

behind the trailer, my desert
Them red clay piles are heaven on earth
I get my rocks off, bulldozers and dirt

The little "bubbly balls" are interesting...makes me think they were created by a crustacean. Some crabs make little balls of sand while burrowing.

The bottom 'bubbly' pics. Look like forams.

I've been encountering these tiny lumpies as well. I noted that a broken one appeared to have minute crystals inside (can't lay my hands on it to photograph). Here is one that had a natural hole revealing a cavity inside. Two shots - one poorly exposed and the other better, but poorly framed. I was trying to think of a method to split a few in half to view the interiors, but so far have not thought of a practical means.

We have had some discussion in the past about the 'bubbly things'. Some members have suggested forams, and some have felt that they are calcite. I have a few that I have photographed, and some pictures of the insides full of elongated crystals. I will try to find and post the picture as soon as I can find it. It seems the jury is still out on these odd finds. They are very prevalent in Jeff's CC matrix, and I haven't seen them in any other matrix that I have gone thru.

Here is one photo...

Thanks, your photo is very like the broken one I encountered.

Oh cool, Mini-Me geodes. It'll take a really small rock saw for these.

Excellent photo Julianna! I too have wondered what these "lumpy" things were.
