I visited an outcrop of the Jurassic Redwater Member of the Stump Formation and found these. I have been drooling over this outcrop all summer on Google Earth and decided to stop off on the way back from Big Wonderful Wy. this weekend.

Cardioceras hyatti from the C. cordatum zone. The bottom photo shows them as found and the top two show them after being subjected to my preparation skills. Notice also the small marine reptile vert. on the right of the bottom pic. from the same concretion.

Makes you wonder why it will snow in October around here, but in December the ground is bare... maybe that is why there are so many trees :wink: a photo of the Early Ordovician Fillmore Formation. Found today, a rock full of imprints of orthoconic nautiloids, probably Protocycloceras. Also a small orthocone with a few chambers and part of the siphuncle preserved.

I can't believe the clarity of those sutures. They brilliantly demonstrate how in such well preserved specimens they can be used as a 'fingerprint' by experts to identify the species.

Lovely finds.

I hope you are taking some pictures of what the site looks like (not the whole field, but a specific spot that you THINK there may be something of interest) before you start digging and put them up on the screen at TONMOCON III. You always make it look like these interesting finds are just sitting there waiting for someone to stumble on them and I am sure it is not so.

With miles and miles of outcrop, some are just waiting for Me to stumble upon them. This one was found about 2 miles from the truck, close to where the pic below was taken. It really was just sitting there. :wink:
