Welcome to Pioneer Fossils!

A Certificate of Authenticity, which has a photo on it of the exact item you purchased, will accompany the specimen.

Here is a superb, museum-grade fish fossil plate from the world-famous fossil beds of Fossil Lake, Green River Formation, Wyoming. From the Eocene, 52 million years ago.

There are 3 fish, all top grade, with no paint or restoration on any of them.  None were inlaid, all are naturally from this plate (in-Situ).  The plate itself is called the Capping layer. It is a thin layer on the top and bottom of the other layers.  The rock here is so hard that only the best preparators can correctly prepare these fish without damaging them, and preparation takes much longer than fish from other layers.

The 3 fish are 2 Mioplosus and 1 Knightia eocaena.  The largest 2 are Mioplosus, measuring 7.2" and 5.6" respectively from tip to tip. The Knightia is about 3.5 inches. The plate is about 10.9" by 9.6", and it weighs 7 lbs. 15.45 oz. (just below 8 lbs.).

All 3 fish look gorgeous, all the details are splendid.  Skulls, vertebraes and other bones, fins, fin rays, etc. are great. Though the larger Mioplosus has its mouth closed, you can still see some of its sharp teeth with a loupe.  In fact, both Mioplosus show some sharp little teeth.

The back side has multiple thicknesses (photo).  This is fairly common with ultra-hard capping layer rock. It is extremely hard and sturdy.

A very important addition to any fossil collection, or conversation piece.

This item, along with all items we sell, is intended for responsible adults. Please keep out of reach of young children.

We will ship this only to the United States.  We are not responsible if the buyer reships it somewhere else, after receiving it from us. Our responsibility ends at the destination we ship it to.  If you take it out of the United States, you are on your own.

COMBINED SHIPPING:  We make every effort to combine shipping costs and we refund any overpayment back to you, on the same day we ship the item.  We have given hundreds of partial refunds for combined shipping savings.  We will do our best to combine purchases to save shipping costs. In some cases, that is easy, in some cases, not as much.  Our items are of vastly different sizes and weights, but we never use shipping as a profit center.  We would rather refund the shipping overpayment back to you, and have a happy buyer.

We are happy to enclose a COA (Certificate of Authenticity).  Some words of caution about COA’s: Do not let them become a substitute for learning about the specimens. We have been working with fossils and minerals for many years, and we have seen hundreds of very nice-looking COA’s, some that are wrong, mis-describing a specimen.

Have you ever received a Certificate of Authenticity (COA) that had no photo on it of the item you purchased?  A COA should be specific to one particular specimen,  with a photo of the item on it.  At Pioneer Fossils, all of our fossils and minerals that come with a COA, have a photo of the exact item you just purchased.  It can never be transferred to a different specimen.
