Today's photograph is for you paleo-geeks ... this nice crinoid stem is from a formation I forget the name of along the western flank of the Sacramento Mountains in New Mexico. If you have some knowledge about crinoids in general, or something specific about this one, please share in the comments. I forgot I had this photo until just now.
