Odontopleurids are known from the middle Ordovician?

Yes, they evolved in the Middle Cambrian and died out in the Devonian extinction event(as did all trilobite orders except the proetids). I have found Primaspis and Acidaspis from my local Shermanian(Mid Ord) and Edenian(Late Ord) rocks.

I found this little bit of a phragmocone in the same outcrop of the Ridley Limestone that I found the Trilobite...

So I've convinced my dog to take care of his umm, responsibilities :roll: around an area where the Ridley crops out down the street from my house. I get to look at rocks while he's sniffing around, along with the little out crop in my yard I get a little mini-hunt most days. All of the fossils from the Ridley in this thread have been found here, the first 5 in this thread and a few others scattered throughout the thread.

Well we set out for our walk yesterday and I caught the faint scent of a skunk, kept on walking, the wind was blowing right towards us and the next whiff stopped me in my tracks so I knew there was one close by. It was about ten feet in front of us and I kid you not it was an orangish color with a white stripe and few spots of black. I had my camera but thought it wise to turn and run home! When I got there I jumped in the car hoping it was still there to get pics. it was and that's when I realized the thing was probably rabid, it would kind of waddle a few steps then kind of flop around, it was strange. It was headed away from me and I got a couple of very bad shots.

Anway... my whole point in telling the story is that I was going back to take better pics. of the fossils I'm going to post, so excuse the pics. and i won't be able to go back until I can get the appropriate authorities out here to take care of the poor thing.:talker:
