I think all of you soft-body enthusiasts will enjoy this. I purchased a TRIARTHRUS from the famous Walcott-Rust quarry on ebay and paid a princely sum for it. Not as princely as most of these are......but princely for me. I think that the reason I won it was that it is not fully prepped and doesn't show as nicely as it could. I primarily went for it because it was 3.5cm long, whereas most of these specimens are less than 1cm. Also.....it's in a ventral position and thus shows the appendages quite well It gets even better. When I received the specimen, and examined it under a loupe.....I saw gills! On the close-up you can see the articulation of the biramous appendages with the gill filaments strung out from one. Tom

Thanks Pete.
The close-up was taken using my new Dino-Scope digital camera. I love it. Sure beats holding my old camera up to the microscope's eyepiece.
Thank you Santa!
Tom

Absolutely stunning. With this sort of preservation, I'm always amazed that you only really get arthropods here and at Beecher's, etc. (I know there's more in a couple of the new sites, though). It must have been a really limited ecosystem. But then, who cares, when you've got gills? ;D
