We recently received an email from the Flint Hills Discover Center in Manhattan Kansas. They are setting up an exibit and requested the use of one of our website images. The only issue was that the image was taken almost 10 years ago, and the native resolution was only 1280 X 960. For most this might be a show stopper. Not for us. Since we seldom collect anything we simply took our best camera back into the field and took the image again. They seemed pleased with the results, and we're definately pleased that they chose to use our image. Sometimes it's better to let things lay.
We made another excursion to the Whetstone mountains, where we looked over outcrops of Mesozoic Limestone, and Permian Colina Limestone. We found a Gastropod that seems to be the same species as a Gastropod we found in the Tucson Mountains. Here are the two images....
Based on that, we believe that this is actually fresh water limstone, and not equivalent to Mural Limestone. Mural limestone appears to be cropping out higher up in the section.
We also looked over outcrops of Colina Limestone and photographed a nice assortment of Permian Gastropods and echinoid debris. All in all it's been a busy time here at Southern Arizona Fossils.
