  1. It'd been awhile since I last joined the Austin Paleo group for one of their field trips, so I was excited to finally catch back up with them at some sites about 3 hrs up north. The plan for the day was to hit up Brady and Santa Anna, but the weather forecast had put things into question. Originally, I had some rather ambitious sites lined up in the Llano Uplift afterwards. The rainy conditions, however, meant the river would be a little too high for walking. After a peaceful morning drive under the guiding light of the full moon, I pulled up to the first location where I was relieved to see things weren't canceled, and Melvin plus the gang were already crawling along the slick exposure of Strawn Group shales (Desmoinesian Series). Upon stepping out of the car, I was suddenly met with a confusing mix of cold drizzly rain and warm gusts of humid wind. It wasn't unbearable though, and I was more so focused on catching up with some familiar faces anyways. The hunting proved a bit treacherous. The ground shimmered with newly formed mud mounds that loved to stick under your shoes. Although it wasn't nearly as bad as wet Grayson/Del Rio matrix (Waco Pit), it was still a strenuous activity, having to climb the hillside in my new platform shoes. Things started off a bit slow. The weather dampened the mood, but with enough effort, people started making some decent finds. I was hopeful to prove my crinoid crown from last year was no fluke, so I went straight to business, closely inspecting every rock for anything out of place. It was a challenge to look for details through the mud. Nevertheless, it was a rich site and everyone kinda knew the spectacular finds would roll out one way or another. After an hour and a half of looking at hash plates and broken brachiopods, I found the first keeper. Especially since it was covered in mud, this guy was tough one to notice. I think 9 times out of 10 I would have walked over it. A small, smashed crinoid crown and arms Nearby I also picked up a small crinoid cup which are always fun to find. As we were wrapping up, I took a gamble wiggling out a mucky mass of what looking like a crinoid arm erupting just from underneath a bigger rock. It didn't take long to figure out it was most definitely a large crinoid crown. The species is hard for me to say, so I am open for suggestion. A large crinoid that took a bit of cleaning. The other side shows some arms, but there is a lot more matrix covering it. With all the rain, Melvin and Ed decided it was wise to skip what would have been a messy parking situation at Santa Anna in favor of an impromptu trip to the beloved Wilson Clay Pit of the Harpersville Fm (Virgilian Series). After about an hour of caravaning northbound, everyone gingerly parked their cars along the gravel margin. It took a bit of teamwork to set up some big rocks for a makeshift bridge across the mote separating us from the gate, but we pulled through. Others gave up a bit too early and decided wet feet for the rest of the day would not dissuade them from taking the shortest route across the puddle . Wilson was a good call as things were surprisingly easy to traverse once inside the quarry. All the rock fragments made for good footing. I had made a couple new friends who happened to be fossil forum lurkers. One of them was named Will, and I decided to help him out with finding some Pennsylvanian shark teeth. Once we located the right rocks, I tried to show him what to keep an eye out for. He was a fast learner and pretty soon we were both consistently spotting little pieces of Petalodus among other cartilaginous vertebrates. Sadly, I didn't find most of my cooler stuff until he was sick of all the hammering and ventured elsewhere to find inverts! The first keeper for me was a mess of associated Archaeocidaris plates and spines. Not nearly as pretty as those of the Brownwood Spillway, but still neat nonetheless. Archaeocidarid plates and spines Not long after, I made a rather unexpected discovery. I guess in the past I wasn't looking at each rock close enough. I had heard of Cladodont sharks being found in Wilson before, but never saw one myself. Over the course of the day, however, I found like 6 of them in varying condition. They are surprisingly common, but go unnoticed because they are usually so tiny. I have seen the species Symmorium reniforeme referenced in Wilson, but I am under the impression that these teeth are now classified as Glikmanius occidentalis. My favorite is the middle one below. Its white coloration makes it almost look like a modern shark tooth on the beach. Cladodont (Glikmanius occidentalis?) shark teeth. Surprisingly common in smaller sizes. "Deltodus" was the second most common shark of the day and I managed to snag one in near perfect condition. "Deltodus" Throughout the day I was really hoping to find a Petalodus as good as the one from last year, but alas it was not meant to be. Still, there were some decent ones that showed themselves now and again. One tooth has some really cool dendritic mineralization on the enamel. Best Petalodus ohioensis of the day. As I was writing the above excerpt on the dendritic Petalodus, I took a second look at it and just noticed a trilobutt on the back of the broken root! First Wilson trilo for me and it's on a Petalodus tooth go figure. I guess there's no other way I'd find one given my vertebrate fixations Trilobutt on Petalodus! It was about sunset when I left. Of course I was one of the last ones there along with Ed and Melvin. I need to work on my controlling my fossil hunting urges for sure. Anyways, it was a nice day for a hunt and definitely something I needed. The 3 hour drive back felt like nothing as all I could think about was what awaited me the next trip out. Thanks for reading!

    Is this a fossil foot?

    I found this near Logan utah, I have another “bone” fossil I found there that I would like to post also. A hater told me it was natural who looked at it in person. I just want to know. I am a proud rock hound. This seems odd to me. I found several horn coral fossils and sea life proof near by. This would have been near a lake bonneville shore at some point. The surrounding seems very sedimentary while the inside seems agatized. Following what looks to be an actual foot and not a print seems you can see the actual outline of how a toe was curled into the mud. There looks to be a total of 3 toes but doesn’t look to be all forward facing by Dino prints I’ve seen so maybe big bird or just the way it laid to rest. I need help please!

    Fossilized mud?

    Collected this a few years ago on the bank of Trinity river near the surface. There was a layer of sorts of this and that's where this concretion was containing a little Baculite poking out. So I'm assuming this is result of some evaporate process and this is gypsum but how did it come about? Was the concretion sitting in shallow muddy water? Hoping someone can explain the process that produced this.
  4. Pottsville Formation, Alabama I would like to peek under the mud on the specimen in the first pic to determine if it is a compression fossil. This film on this particular sample seems brittle so I have to be careful. I can see pigmentation under some of the mud - that is where I want to work. Ideas? I hope I’m using these terms (carbon film, compression fossil) properly. I included other pics of other specimens that have carbon film or some type of mineral imprint (not sure what the term for this is) that I am to cleaning, sorting and comparing to potential compression fossils from Carboniferous. I was initially ignoring the specimens that look like pattern could be iron staining- thinking all were Liesegang rings, but I’m not sure that explains all of them.

    Is this a septarian nodule?

    Is this a septarian nodule? If not, what else could it be? Found in Germany. 4 centimeters.

    Best Tool for Cleaning Mud ?

    The best tools for cleaning dust and rock from artifacts are Chisels and Brushes , and what to do when the conditions are wet ?
  7. We've been having a warm spell here in southern Germany for almost a week now, which gave me the chance to check out my favorite spot in the ditch in the Danube Valley where the Kimmeridgian ammonites can be found. I had done a drive-by about ten days ago to check it out, but although the snow was almost gone at the Lake of Constance where I live, it was still piled up to half a meter in the valley. But like I already mentioned, the temps have been well up over freezing for a good week now, so I figured I'd have another go. Knowing that the spot I wanted to work at was in a hollow, I took along a large measuring cup in order to bail out and was prepared to make dams and sluices. So I was looking forward to a mud bath and that's just what it turned out to be. It was worth it in the end as you shall see and besides, anything is better than being cooped up at home because of you-know-what. I took these shots when I arrived, so you can see what I had to cope with. The layer I want to get at is under a foot of water at this point. Here's my trusty measuring cup after the bail-out and a bit of shoveling and hacking. So now I could get to work at the layer. And here come the first ammonites. These ones are small and hard to see because of the mud. Continued...

  9. I've tried everything I can think of to remove this mud that is caked on so many of my newly acquired specimens. Every time I use my brush to remove the mud the fossils beneath become horribly disfigured. Any ideas for how to remove the mud and keep the fossil intact at the same time? I can't use water because the rock is soft and cracks when wet. Any brush recommendations? Currently I am using a standard paintbrush.

    Muddy limestone

    I have some fossilsfrom kinnekulle. That when wet can be little muddy. I try to clean it with a toothbrush but it wont clean and it looks like this after. Any ideas? theres a picture of a orthoceras being wet and dry. So you can see how its not good looking when dry.

    Fossil IDs (if possible)

    I like collecting fossils, but I usually am not sure what my finds are. Please, could you help me identify these fossils? I noted down some possibilities down below. 1 - could be a late Albian ammonite from central Serbia, but I am not entirely sure. Acquired in Serbia. 2 - Found at Southerndown, Wales. Could it be a tree root or something in the region of that? It has a cross-hatched pattern if you look closely. 3 & 4 - A shell I found at Penarth, Wales but I am not entirely sure what it is called. 5 - A bone I found in the mud at Tites Point, Severn, Gloucestershire. maybe a birds? 6 - Some shells I found in mudstone at Charmouth, England. Was found in the same stone as 7. 7 - wood I found at Charmouth? It was very crumbly and delicate. 8 - A Trilobite fragment possibly, Llanfawr quarries, Wales. 9 - A bivalve I found in Southerndown. Not sure what it is though.
