First hunting trip of the year and its a home run!
hadrosauridae posted a topic in Fossil Hunting Trips
Well, 2 days ago I was freezing my butt off in Chicago and today its almost 90 degrees here in Oklahoma! But warm dry weather is perfect hunting time, so I headed out to a ranch I started searching last year. After many hours of walking and eyeballing every bit of rock exposure, something finally caught my eye. I immediately recognized the bone structure, marked the spot and kept searching. More and more bits started to show up and I immediately recognized the "figure 8" shaped that is distinctive of the sail spines of Dimetrodon! This is the animal I have been hoping to find since I began my research into Oklahoma fossil locations. I was super excited. These were found on surface as "float", so I marked every spot with engineer tape. When I couldnt find any more, I stood back and looked at a perfect triangle pointing to the highest spot where I found material, and it was also several bits together. So now I have an arrow pointing to my dig site. My only hope is that I am just finding the tips (since almost all of it was sail spine bits) and the rest of it is still in the ground waiting. Fingers crossed. Even if this is the only parts left, I'm still super excited. Most were sail spine bits and some were BIG, huge compared to what I saw on my day of digging in the Craddock bone bed in Texas. Also a few other bits that might be pieces of rib or limbs. Also, 2 bits of Orthocanthus shark headspine (actually the first items I saw) and 2 coprolites including 1 that has visible bone bits in it! @thelivingdead531 I know its been 3 years, but I'm a heck of a lot closer to finding that Ddon tooth I promised you! My field collection collection Dimetrodon sail spine bit That distinctive shape for sail spine! and another one Everything brought home Not a great pic, but the light spots are bits of bone in this coprolite. Othocanthus spine pieces. Ortho head spine showing denticles 2nd ortho head spine with denticles

My latests hunts to my Permian sites have been slim. Still trying to narrow down the producing layer(s), but my test excavations have been dry so far. If you remember in my last thread, one of my spots was almost buried by overburden from a dozer work above. I had a strong hunch that there would be fossils in those debris pile and I just needed some rain to start washing it down. I was right! We have been getting quite a bit of rain lately and its helping uncover more. Last week I found a couple pieces of an Orthocanthus texensis (Permian age shark) head spine. I have found many pieces like this at this site, but these 2 parts went together making about a 3 inch long section. My biggest piece yet! Today, 2 more pieces were found. This section had lovely denticles! While cleaning and talking about them with my son, I got out the last section to explain the how the complete spine would look with the smooth lower, and barbed upper pieces.... AND THEY FIT TOGETHER! What made is more amazing was that the base section was found very high on the pile, and the barbed section was at the bottom. The break on the tip is recent, and I have hope I might still find the last 1.25 inches to make this 100% complete. I might just try digging and sifting for it. Its a narrow water-dug path these came from. The base section was wedged sideways up high, maybe the tip was flushed all the way down along with the most recent find.

I had the pleasure of arranging a special fossil hunt to the Red Beds of Texas - a famous Permian site that was originally described by Copes in 1870's and later by Romer. It's an old quarry on private land that we were able to take a group of 10 to hunt on. And I was corrected by our guide that it was really not so much a "hunt" as a "collect" because the fossils were literally EVERYWHERE! You could sit in a 10 foot radius circle and be picking up vertebrate material all day long! We collected for about 5 hours and everyone came away with some fabulous fossils. Lots of amphibian skull pieces, sometimes with jaws and teeth sockets, vertebrae, lots of little toe bones, shark teeth and spines and much more. Most were small things, but occasionally you'd fine a nice big vert or piece of bone. Full Dimetrodon skeletons have been recovered from this site as well as amphibian Eryops and others. Here are some of my favorites from the "collection"! Dimetrodon toe bone: 3/8 inch Amphibian Eryops Toe bone: 1 inch Eryops ungal (toe bone) 1/2 inch Eryops jaw and tooth sockets - 1 inch Amphibian skull fragment (the biggest bit I found - 1 1/2 inches) Eryops Tooth: 1/4 inch Another jaw fragment - 1/2 inch An unknown tooth: 1/8 inch Orthocanthus shark tooth (Fresh water shark - there were HUNDREDS if not thousands of these teeth, but rarely do you find a complete one. Some were big, almost an inch, but this one was 1/4 inch) The blue color is amazing Some awesome little amphibian tooth plates, all around 1 inch This one has little teeth that look like hersheys kisses! smaller one - 1/2 inch my best vertebra (found about 4 but most were crunchy). 3/4 inch A lungfish tooth 1/2 inch Lots of other bits and pieces of bones and spines: This is a Dimetrodon sail spine fragment. Some of the others found even better bits. 1/2 inch Edaphosaurus spine spur (a different type of Dimetrodon). Size 1 inch I can't wait to go back out again - I hope to find a Dimetrodon claw (a couple of the group did). Next time!!
