It's been a couple of weeks but it's taken me this long to take all the photos of my fossil finds from my trip to Oklahoma with the Paleontological Society of Austin! Our yearly trek to find Silurian, Devonian and Ordovician finds (not much of that in Texas!) was a great success again, thanks to our OK friends! Since it's just over a 6 hour drive for me, I went up early on Friday to hit a couple of "non field trip" spots before our "real" field trip on Saturday and Sunday. I had heard about a Permian site that I was excited to check out. It's a weird barren moonscape in the middle of a field. It was a bit warm.....and the sun radiating up from the baked clay was....intense. Fortunately a cold front was on the way so I kept reminding myself that the 90's of this Friday would recede into memory. But yeah...it was hot. There were bone bits everywhere....everywhere! But they were pretty crunched up. I didn't find much more than a few not-well preserved vertebrae, some okay bone bits, a few nice little amphib teeth and a couple of quite nice unbroken orthocanthus teeth. Tiny tiny ones, because all the big ones break easily. While I didn't find a lot of quality stuff initially, I did haul out about 60lbs of matrix so I can look through at my leisure at home! I learned a valuable lesson though...take two smaller buckets rather than one large bucket. It's a LOT easier to haul out two 30 lbs instead of one big haul a quarter mile over rough terrain! A little amphibian tooth: EDIT:...I thought these were Amphib teeth, but apparently....they are Orthocanthus Shark coprolites! hahahhha They are 1/4 inch each What is most amazing about these fossils is the color of the preservation. Astounding reds, yellows and purples. The little Orthocanthus shark teeth that were mostly complete. The Permian "moonscape": I decided to hit one other site before I headed to Ada where we were all meeting. It was the Ordivician site that I found a lovely Oklahomacystis echinoderm last year. The cold front had moved in and the temperature dropped almost 20 degrees and was just LOVELY hunting! I didn't find any more Oklahomacystis and wasn't finding much except a few nice brachiopods, but then I saw a crinoid calyx piece upside down (all I saw was the edges but I recognized it as crinoid) picked it up and got a nice surprise!! Too bad it's not the whole thing and just one segment, but I'll take what I get! It's a beauty...the geometric patterning is amazing. It is a Pleurocystites echinoderm. It's 1 1/4 inch wide. Early on Saturday, the whole group goes to Yellow Bluff which is a huge area above a creek and up a hillside. It's a great site with a plethora of fauna. It is completely possible to spend an ENTIRE day there! But first we had to drive through the pasture and the cows! They were nice cows. Yellow Bluff - It is primarily Silurian with a cap of Devonian at the very top of the hill. It is Henryshouse formation (which I keep wanting to call Harryhousen.... hahahha - that's for any of you old school animation lovers out there) And not only were the fossils abundant, so were the Missouri Primroses! A few nice finds in the field- A Gastropod Platyceras, Crinoid cup - I think this might be Ollulocrinus? A pink Brachiopod! Here's that pink brach again: I found a couple of Trilos, nothing quite good (last year I found the best one!!) but I did find one large one which still has lots of matrix on it, an interesting half a one, split vertically, not horizontally and then some others not very well preserved. This is an odd bit of crinoid : not sure what it is: So aside from the above pics of the in situ pieces, my only other really good find was this brachiopod Dictyonella. It was originally thought to have a bryozoan growing on it, but turns out it is actually the pattern of the brachiopod! There was also this cool bryozoan which I thought was a horn coral when I picked it up, only realizing it was bryzoan as I photographed it! It's 1 1/2 inches in size! But I did bring home a bucket of matrix and am having fun going through it, so will post some of those at a later time. Oh, and there were scorpions out and about enjoying the cool weather too. Hopefully no scorps in my bucket of matrix..... if so, now they are Texas Scorps. So Sunday was Black Cat Mountain Day. If you are not familiar with the trilobites from Black Cat Mountain...you are in for a google treat. Of course, finding the rare trilobites is.....rare. But there are plenty of other amazing things to find at Bob's quarry! The Quarry is Devonian with Haragan and Bois D'Arc Formations. But the trilobites are of course, the favorite. While I love the rollers the best (not sure why, I just do) I actually found better "open" ones this time than rollers! All of these are about an inch long. Paciphacops sp. Kainops sp. and not sure what this one is...probably Kainops and a surprising find of a (sadly not complete, but more complete than the typical) Huntoniatonia huntonensis Usually you just find the pygidiums...they are ALL OVER THE PLACE and they get HUGE. The biggest pygidium I found was 2" x 2"...just the trilobutt! It would have been a monster trilo. But the brachiopods are almost as amazing as the trilos. My favorite is this Howollella (I think) covered in Beekite: This is a big silicified Anastrophia (1 inch) An interesting Meristella with some crystals Orthostrophia and a neat coral which I think is Syringaxon perhaps? And one of my favorites to find - straight shelled cephalopods. This by far the most intact one I found. They are usually only three or four chambers but can get to be almost an inch in diameter. This one is 5 inches long And finally , my other favorite find from Black Cat Mountain.....a beautiful bryozoan ring:
