Your stories are needed for the Digest Newsletter!

     One comment that popped up from a lot of folks at Expo was that people would enjoy seeing more frequent club newsletters. To do that, we need YOUR STORIES - the Digest Newsletter is member driven, and submissions have dropped off in recent years.
     The stories do not need to be fancy ultra-scientific things! Such simple topics as a favorite fossil collecting trip story, or a description of some great fossil find of yours would be just the sort of thing we could use in the newsletter!
     Submit your pictures too - really cool ones just might end up on the cover!
     Please send your submissions to the Newsletter editors, John Catalani or Chris Cozart; alternately you can contact one of the webmasters - our contacts are listed in the lower right corner of this page.
