Bright Angel Shale - Thorax images from our SW site in Arizona

[Arizona Chris]

Greetings everyone,

 

Finally finished our write up on the section illustrating images of the thorax components we found of the rare lower middle cambrian trilobite Zacanthoides walapai at our unique site south of the Grand Canyon near Ashfork.  Although we wished for more complete specimens, a scan of the literature shows that most finds are very fragmentary on this species, and to be able to illustrate some additional specimens in good detail was sheer pleasure for us!  We have found only 3 or 4 other localities outside the Canyon of Bright Angel Shale, and this is the ONLY one with Zacanthoides.  Thank you all again for your interest and past comments on our work in the BAS, and we hope to keep posting more images in the future.

Keep digging - maybe there are spots where you can dig out larger chunks with a better chance of finding a complete one? I have been collecting at my local Cretaceous site for just about 9 years now and finally found a complete Uintacrinus with head and arms just recently (after a number of partials and nearly-completes).
