New Members Garter Snake Posted March 23, 2021 New Members Share Posted March 23, 2021 I've been trying to identify multiple fossils found recently in deposits associated with the Glenns Ferry/Poison Creek formations of Lake Idaho. Here are a couple of photos of fossil jaw bones with teeth collected recently and an aggregate fossil containing petrified wood, fish bones, veterbrae and a jaw. I believe the large jaws are from Mylocheilus robustus. The smaller jaws, I am unsure of. Collected near Grand View, ID and all fossils were associated with Oolite deposits. 1 Link to comment Share on other sites More sharing options...

Oregon1955 Posted March 23, 2021 Share Posted March 23, 2021 Pliocene I believe. I did some collecting in Lake Idaho deposits in far eastern Oregon when I was a boy. Some really beautiful red glossy fossilized fish bones very much like those in this post. I believe there are some previous posts here on TFF on finds from ancient Lake Idaho.

New Members Garter Snake Posted March 23, 2021 Author New Members Share Posted March 23, 2021 From my reading, Lake Idaho was around at varying levels from 12 million years ago until 2 million years ago. The large bones are 2-4 mya. Link to comment Share on other sites More sharing options...
New Members Garter Snake Posted March 23, 2021 Author New Members Share Posted March 23, 2021 I have a question. I found some fossils I wasn't able to identify. They have the great desert varnish on them. They are also associated with Lake Idaho/Oolite/Poison Creek formation. Can anyone identify them? The photos are the same pieces flipped over. They might just be rocks. Link to comment Share on other sites More sharing options...
