Had me some "Stromatolite" and didn't even know it...... Did some research on it and the age is supposedly the oldest fossils on earth (Or close)...They go from 1.5 billion to 3.4 billion years old....(How cool is that)... Was going to cut it and (or) work it,I think I will leave it alone     |

About a 45 minute drive from where I am living now (where I used to live) there is an area where you can pick up pickup loads of the stuff that has the swirls on the outside of it. A lot of the people in the towns of Greybull and Basin have areas in their yards stacked full of it and some of the pieces would take two people to carry them. We set a new mail box post and stacked a bunch of pieces around it for added support. The pieces with the swirls on the outside are impressive
I think there are a couple of pieces laying around here so if I can find one I will send it to you. It either is or is close to the longest living thing on the planet because they are still alive and well ......... somewhere that I can not remember.

Agreed. Pretty cool to have something so old in my home. Besides us!

there is still a living colony in Australia. Shark Bay if I remember right.
Also worth noting that not all stromatolite is super old. I think some of Wyoming's is "only" about 100 million years old. Amazing stuff!

I believe the Providence Mountains in the Mojave are entirely capped with a not very attractive version.

Silicified Stromatoporoid Chert from Tennessee! Ordovician in age (around 450 million years ago). Technically, it is called Bigby/Cannon Chert because it comes from a limestone formation of the same name. Knaps great when the banding is fully silicified!    Michael |

You can see in the cross section it is not very impressive unless it is totally agatized.  Way cool as a yard rock though with all the swirls.  Jim |

Nice chunk you've got there fossilman. It's quite common over our way.   Sometimes get some pretty good colors in them. These are Eocene, from what is probably a beach deposit. Russ |
