With things slow in the fossils and history forum I will start posting some pics of things in my collection.

First is a crushed shell of Stenolobulites sinuosus from the Permian Meade Peak Member of the Phosphoria Formation. Also what was referred to Cornaptychus back in 1964, is it a Jaw Operculum or Bivalve?

:smile:

For those with access, here is the article (or the first page for the rest of us) by Closs, Gordon and Yochelson describing the cornaptychi. The genus Pseudogastrioceras has now been referred to Stenolobulites.

I thought I had a paper stating they were bivalves but I must have been dreaming. :oops: They do have the morphology for aptychi.

Stemmatoceras aff. S. albertense, a Jurassic (Bajocian) ammonite. The flat spot in the center is a vein of calcite. The hole next to it is a geode, formed inside the shell chambers which have been destroyed by all the crystallization.

A few old pics from back in '88

Helpers I had in the field back then.

And a photo of my Father in a Trilobite quarry.

Those ammonites are Prionocyclus macombi, that was a little glory hole I took my two brothers and their kids to, they can still be found but not alot congregated in a small spot like that.

We were digging for Modocia typicalis trilobites in the Marjum Formation, dig all day for 1 or 2 but there were alot of little agnostids. The trilobites found in that quarry split on their ventral side so you have to glue the two split pieces back together and prep down from the top to get to the fossil, very time consuming, but well worth it.
