  1. Saturday the Paleontological Society of Austin visited the "Waco Pit". For those of you who are not familiar this is a very large borrow pit from which the US Army Corp of Engineers dug material for the building of the Lake Waco Dam here in Central Texas. The pit exposes the Del Rio clay which is part of the Washita Group, Lower Cretaceous (earliest Cenomanian Stage). What makes the pit special is that it produces a really interesting micro fauna along with the normal sized fossils common at other locations. The microfauna includes lots of tiny pyritized ammonites and other mollusks. When we (daughter and a friend) left Austin it was drizzling and foggy but despite the serious threat of storms we stayed dry the whole time. In fact the cloud cover and breeze made for a nice day. But lord it was still muddy. The clay sticks to everything and for every ten steps you pick up 10 pounds of muck. As you try to pick up the little micros they would get covered in mud and you just hoped the ball of clay you slipped into a bag still had the fossil with it. Rinsing it all off after getting home was fun since it was like finding them again. Sorry I don't have location shots. Being covered in muck I was hesitant to even touch the camera. Here are some photos of the variety of stuff. My two best finds are the nice shark tooth and the Rhyncholite. But there are also plenty of good to decent ammonites and other shells.
  2. Two experienced veterans here took me to one of their favorite collecting spots and together we searched the area and came up with many fine specimens of ammonites, clams and gastropods that defined the food chain and some of the more common species. Being new to this I would have to rely on them or others for proper identification, but the ecology of the site became crystal clear to me as I implemented my survey technique. Unfortunately my site photos were accidentally erased on my camera but I will take and post more on my future visits. The site is dominated by a gently sloped mesa capped by an upper Cretaceous shale interlaced with calcite crystals. These are contained in rusty brown clay ironstone and limestone concretions. The soil is very sandy and easy digging. Buried very shallow under it are brown to gray nodules about 30-5- cm in diameter. These are easy to split open with hammer strokes and contain large numbers of molluscs and ammonites. A 3 meter by 3 meter area was examined down to about 10cm and contained a single outcrop of shale and limestone which was broken down to 3cm pieces. Anything of significance was examined and representative samples collected to be photographed and examined for identification. Any help others can provide in identification is appreciated. Photos follow.
  3. Made it for another dig in the South Pit of Hungry Hollow! I decided to check the bottom of the hills and found 2 rather small but beautiful enrolled trilobites. It's amazing to me that they even made it to the bottom as they would have had to avoid a bizzilion cracks to get there. I guess I was meant to find them. In the first photo you will see the smallest one circled on the top left. The second photo is him - isn't he cute?? That's pretty much my find for the day - nothing too spectacular but all the small stuff I am compelled to pick up and bring home with me. I don't know what it is about those crinoid sections that fascinate me so much. Especially the unusual ones with the little spikes and scalloped holes in the middle. It's still cool enough to enjoy the day and it has been dry enough for both pits, however it rained a lot yesterday so I imagine it will take a few more days to dry things up again. Once the really warm weather comes I may not be digging quite as much so I am taking advantage of this time now!
  4. Ventured out this morning for a little bit. It was a windy day for sure. My first find of the day was hiding from me (hence the title)... You never know if what you find will actually be whole or not. In this instance, it was actually 2 ammonites. Venturing on I took a few shots of this and that...for those who have never been to the lake, these are in slabs all over the place...They are pretty in color. Here's a few more of my finds from the day. And here's a few from a couple hours after work one day that I went exploring. Just thought I would share...
  5. Good'ol Rio Puerco

    Well, once again (as you will see, I spend much time here ) I was back in the Puerco. I was on a mission for a nice romaniceras mexicanum (which I did not find). My search brought some nice gastropods... ...and some very cool ammonites! This find made my day (though, it will take another trip to get it home)!... ...all the more reason to go back.
  6. Good Ol' Rio Puerco

    It had been a while, but I finally got out for some collecting last weekend. Some friends and I camped out in the Cretaceous Marine outcrops of the Rio Puerco. The morning started out with small handful of ptychodus teeth. The rest of the day was filled with some nice spathites and coilopoceras ammonites. Good friends, great day, excellent finds! At night we got the black light out... love this little guy. Can't wait to get back! Happy Spring!!!
  7. Pennsylvanian Fossils And More

    This post will have several posts underneath due to having larger photos this time around. February was my birthday month and what better way to celebrate my birthday than to convince the family to go fossil hunting with me right?! We headed to the Jacksboro Spillway for a day of hunting. Roz was already there when we arrived and as usual it's always nice to see her. This was the first time that I have ever been to the spillway and it's always a treat/shock when you arrive somewhere you've never been before because 1) you never know what you will find, and 2) you have to adjust yourself to finding the type of fossils that are in the area. In this instance, it was Pennsylvanian fossils, and I am used to searching for fossils from the Cretaceous era so adjustment in the eyes was definitely a must. This is a sample of what I found: It was a beautiful day and I consider myself fortunate just to have had my family hunting with me. The next day, my actual birthday, fossil hunting was not necessarily on the agenda, but I couldn't go the day without finding at least one fossil, so I convinced my husband to take me for a quick trip to the lake (Texoma) and in less than 45 minutes this is what I found: So considering I did pretty good. On to the next trip:
  8. In the Blue Hill Shale Member of the Carlile Shale formation, you can sometimes find concretions that have very colorfully preserved ammonites. The concretions are usually about the size of a golf ball to baseball. They are smacked with a hammer to see if there is something inside, as many are empty. The concretions are extremely hard, but there is usually a weak spot between the ammonite and the super hard limestone. I recently picked up a CP air scribe, so I thought I'd try it out on a "mud ball" that had a little of a Scaphites carlilensis exposed. The outside of the concretion that is light gray is fairly soft. The dark gray interior is too hard to do much with. I found that if I worked on a part for a while with the scribe, a crack finally developed somewhere on the concretion. After working on the one in the lower part of the first photo, I found that it had another ammonite right next to it. This one was a Prionotropis hyatti. After a lot of work removing matrix, finding a couple tiny "extra ammonites" in the same ball, and gluing parts back together I finally arrived at the finished product. The camera does not do the color justice. The purpleish, pinkish, reddish, rainbows just don't show up well, but as you probably gathered from this long post, I'm kind of happy with the results!!

  9. i am going fossil hunting in Montana in June. i am wondering if there are any sites that yield good ammonite fossils in the eastern part of Montana(around Glendive, Baker etc.). if anybody could provide me with any information, that would be great
  10. Im looking for any information regarding Ammonite aptychi Lower Jurassic (Torcian) near whitby North Yorkshire Coast . Is this a certain type of Ammonite you can find bit confused im afraid. Have wrote it down for things to look out for on my next visit.
  11. Hey all, After a horrible busy year @ work .. I finally got the chance to go for a few quick trips. For me this means the awesome beach of Cap Blanc Nez, France. Not too much wind, a lot of ppl that searched during summer .. I wasn't expecting much, it was as important to be out oce more then to collect .. I'm sure you know that feeling :-) It's about a 50min drive from my place .. so I mostly go for a morning or more rarely some afternoon. Depending on the tide and, oh yes, my work. This is from 2 times 3-4hours searching. I have to say, the second trip, there was at least 200 people looking for fossils. It's a popular place for excursions from schools and universities. As was that day .. Nevertheless, it helps if you know what you are looking for (this being one of fossil' hunters most important keep-in-minds). These just came out of paper last days.. I hope I'll get to show you the preps of these ..we'll see... There are Ammonites Belemites Fish vertebrea Hamites sp. Turitella sp. Shark tooth Inoceramus sp.(and others) petrified wood (partially pyritised) .. Edit: Finds are Albian and Cenoman of age (middle-Cretaceous)

  14. Went hunting in TXI cement quarry with the Dallas (TX) Paleontological society a couple weeks ago. I never seem to find good teeth in the Atco so I started looking for anything interesting in the big piles of Eagleford shale. Found these tiny pyritized ammonites, which are pretty cool... All the photos were taken with my iphone through a binoc scope, which works pretty well, apparently. Most of them are less than a centimeter in diameter.
