I'm a rookie. This is my second post. I've been out on two "expeditions" and made some interesting finds. When I picked up this fossil?, I noticed it was caulked on the back side, I found that perplexing. North East Texas, Fannin County, Eagle Ford Group, Ozan Formation, North Sulfur River Bed. It appears to be a vertebra. Please help identify. Thanks!

On Sunday afternoon I went out with Keith Minor to a North Texas site exposing the lower Arcadia Park formation and (possibly?) the top of the Britton Formation (lower Turonian, upper Cenomanian respectively). The hunt almost never happened after various storm cells were menacing us and the high winds were thrusting cranes into sky scrapers and whipping up emphysema inducing dust clouds. Yet, even though everyone around us was getting Kansas blown at them, we were only exposed to the high winds and rain so cold and blown so hard that it felt almost like hail. But that lasted for only a few minutes, leaving the rest of the day to muck around in the Turonian while the winds blew most of the clouds away by hunt’s end. The Kamp Ranch Limestone is exposed very nicely at the site, as well as meters of shale beds above and below it, making a short study of the successive stratification obligatory. FIG 1: The roughly 38 cm (15 inch) thick Kamp Ranch jutting out amongst the soft shale and clay above and below it. The clouds foretell the showers to befall us. (ID request incoming)

A few weeks ago I was working an exposure of the middle Turonian Kamp Ranch member of the Arcadia Park Formation in North Texas, using a chisel and the natural bedding planes to pull up slabs. I had been there less than 15 minutes and had only found one small, broken tooth amongst shell hash when I found this almost perfect medium sized Cretodus crassidens. I also found some smaller shark teeth including Ptychodus sp., miscellaneous vertebrate material, and ammonites of possibly multiple species. So far this specimen is my largest from the site The first thing I noticed about it was the white color of most of the enamel and strange patterns covering the exposed tooth. It looked like it had been recently exposed and weathered, but since it was only exposed by me pulling up slabs that is not possible. All the other teeth I found there didn’t have this type of preservation but had the normal brown enamel. I have searched for pictures of any other teeth with patterns like this, but so far nothing. I prepared it out of the rock and can see that the patterns occur on both the front and back of the blade and root. It is 35 mm diagonal and 25 mm root width. It was resting just a few millimeters above a large inoceramid shell. The tooth is perfect except that the tip of the left cusp broke off before fossilization. There are certain areas where the blade isn’t white and there are no patterns, but for the most part the pattern covers the tooth. I was also able to rub off a bit of the white with my finger, but it seems that the patterns are embedded in the tooth itself since it is also on the root. Here are some pictures. I am hoping the origin of these patterns can be explained and any links and/or pictures of other teeth like this can be provided. The first three are before prep and the rest are after. Thanks in advance! FIG 1. FIG 2.

I recently went hunting for my first time in the Turonian Arcadia Park Formation, an Eagle Ford group shale formation in North Texas. I found some great fossils, but many of them are fragile. I found a Worthoceras sp. specimen in matrix that seems to be on the verge of falling apart, and a very small Metoicoceras sp. specimen in a similar situation. They both have the nacreous shell preserved. Many of the other ammonites that I found tend to flake bits of the white shell while I am handling them. What can I use to consolidate the specimens so that they don’t fall apart and so that the shell doesn’t flake off? Will the consolidants dampen the beautiful iridescence of the shells? Here the two most fragile specimens, the Worthoceras sp. and the small Metoicoceras sp.: FIG 1: Worthoceras sp. FIG 2: Metoicoceras sp.

I know this is a concretion, but I think it is so cool looking. It has weathered so differently than almost any other concretion I have ever seen. Most layers of this type of material come off in a lot thicker layers. It is possible that is just how it weathered, but I am wondering if there is more to it than that. The layers are so thin and fine. I found yesterday while out hunting in a new favorite spot in the Britton Formation of the Eagle Ford group in Collin county Texas with Joe AKA @Fruitbat. The area I found it in is full of concretions. Many of them have fossils inside of them, but they’re a dark, brick red. The fossils are generally cepholopods, both ammonite and baculite, Inoceramus clams, other pelecypods and gastropods. This concretion is from a layer above the brick red concretion layer I think. I have concretions from all over. Some are cool colors and shapes and some have fossils inside, like my Mazon fossils and also Carboniferous ones I collected in Oklahoma. Also those that I’ve collected in the North Sulfur River and Britton Formation, but this one is unique it it’s own class. Any thoughts on it would be appreciated. It seems like concretions come up so often we ought to have a concretion section on TFF. Of course most of them come up in the fossil ID section. Anyone know the term for this type of concretion? I assume it formed by repeated thin layers being added on slowly over time, which now are eroding away. Thing is I didn’t find any others like it. I’ve been to the area 3 times in the last week. Why would just one concretion be like that? Side 1 Side 2 One of the long edges. The other is flat and solid looking rock, kind of like the bottom end of this one. End 1 different angle that looks a lot like wood, but must be just cool layering and weathering effects. End 2 the typical layered concretion look.

Here is a prep I did of a Notopocorystes (=Ferroranina dichrous) nodule (Eagle Ford Group, Late-Cretaceous, Texas) that I got from @Suvi in a fossil trade. This particular specimen had its limitations in terms of missing legs and parts of carapace. I think it is a molt (note what looks like disarticulated ventral exoskeleton on left of top center photo). Luckily, she included several more nodules that may have more complete specimens. This was a good practice one.

Would this be a mosasaur limb bone? Also I found this tiny crab looking thing? From the eagle ford of far north central Texas. 86-92 mya. Thanks
