Just a note that James Cullison's 1944 monograph on the rocks and fauna of the upper Lower Ordovician of Missouri and Arkansas is now freely available for download or perusal at https://archive.org/details/paper-cullison-1944-the-stratigraphy-of-some-lower-ordovician-formations-of-the This publication has always been devilishly tough to get a hold of. A nice systematic paleontology section deals with the many gastropods and other mollusks as well as the less diverse brachiopods, trilobites, and sponges. The monograph covers the following formations as currently accepted in Missour-

Help request! I am putting together a tool for judging rock age based on very crude, whole-rock, hand-sample observations of fossil faunas/floras -- the types of observations a child or beginner could successfully make. I view this as a complement to the very fine, species-level identifications commonly employed as index fossils for individual stages, biozones, etc. Attached is what I've got so far, but I can clearly use help with corals, mollusks, plants, vertebrates, ichnofossils, and the post-Paleozoic In the attached file, vibrant orange indicates times in earth history to com

Hello forum folks I went to DSR again yesterday 10/05/19 as I had another free day to go collecting. I may not being able to fossil hunt until the end of the month so I had to take advantage! I have been noticing the phyllocarids are coming from certain intervals lower in the quarry...could be nothing....could be somthing....before I assumed I figured I should test it. I knew the exact bedding plane my last Echinocaris came from so I planned on opening a shelf on that bedding plane. My thought was if I could find another phyllocarid on that bedding plane maybe it coul

Hi, I found these ammonite specimens in the Oxfordian Ammonitico Rosso facies from the Baleriac Islands, Spain. I know that the preservation state is quite poor but I would like to get some help identifyng the genus and species. I am not familiar with ammonite description but here you have a very basic description of what I see: Specimen 1: No ribs, oxycone/discocone, involut, carinate? Specimen 2 (Taramelliceras sp?): two pair of ribs (primary and secondary), oxycone/discocone, involut Specimen 3: No ribs, discocone, carinate? Specimen 1

Hi all I have been interested in fossils for quite some time, and have been looking to learning about biostratigraphy and sequence stratigraphy such that I one day might be able to pair my passion with my work (geologist). Have a couple of friends that have recommended me a course held by Avada Oil and Gas which can be seen here: http://avadaog.com/applied-biostratigraphy-sequence-stratigraphy/. They have been very satisfied with their training, but I wanted to understand what experience other people might have? Do you know of any other courses? If yes could
