I took my first long trip (more than 15 minutes) to search for Permian fossils in the Kaibab Limestone of central Arizona near Pine. I have previously only collected silicified fossils that had been transported south of the Mogollon Rim by streams. The Kaibab is known for two silicified fossils that are great index fossils for the Leonardian (Kungarian) Age across western US: Peniculauris bassi, a brachiopod and Actinocoelia maeadrina, a sponge. At first I was disappointed because I have heard that you could collect hundreds of each type in a short period of time. However I found a couple of sponges with the best 3 D texture that I have seen on the internet. They each are each about 13 cm in length. I will take quality over quantity any day. The Peniculauris bassi brachiopod is about 5 cm wide. I also found some very detailed echinoid spines (3.5 cm field of view). I will have to go back to the top of the Rim to collect more types of fossils. I only have a few hundred square miles of Kaibab to search, exclude that near the Grand Canyon. Good reference on Actinicoelia maeadrina: Griffin LR (1966) Actinocoelia maeandrina Finks, from the Kaibab Limestone of northern Arizona.
