Perhaps the most definitive, lasting project I've had during my short time in paleo is the excavation and study of a basal mosasaur skeleton my step brother and I found in September of 2021 (If you missed it, it's in my blogs on my profile). The site is on a fairly inconspicuous outcrop of the Eagle Ford formation, in a zone that's atypical for the upper eagle ford, as the rock itself is very condensed compared to what is usual for the upper kef. Notably, while Mosasaur material is very, very rare in the kef (kef is an abbreviation for the Eagle Ford formation), it pokes out with greater frequ

From the album: Post Oak Creek
P. atcoensis was a rare species of durophagous shark that lived during the Late Cretaceous. Its contemporary P. whipplei was far more abundant and tended to have a higher, bullet-shaped crown; this disparity in morpholgy suggests they may have preyed on different things. From Shawn Hamm's thesis: "Diagnosis. Tooth Crown high and rounded, oriented 90° to the margin area in the medial files; crown crossed by six to eight thick, chevron-shaped parallel ridges; lateral files have moderately high crowns with four to five parallel ridges; posterior teeth are low crowned with two to three ridg -

@Uncle Siphuncle has a great saying that I think of often - "To the motivated go the spoils". To embody that sort of spirit, I have focused my efforts into some hard to reach places in less than ideal conditions, and not always to success. But, now and then it pays off... I was back home for the holidays, with ample Cretaceous strata in every direction. I have been looking forward to this planned week and a half bonanza for months. With the Ochem monkey off my back, my thoughts were now more pleasantly filled with Cretaceous sea life again. Finding it easy to wake due to the

Eagle Ford Shale with Teeth from Central Texas
Jackito posted a topic in Member Fossil Trades Bulletin Board
I have some extra shale pieces I'd like to trade. The shale is from Central Texas, and is cenomanian/turonian. Pliosaur, plesiasaur, mosasaur, and coniasaur is possible but really rare. The most common teeth are shark and fish and assorted bits. I've seen very few invertebrate material. Mainly shell and shell hash. The piece I have for trade has a two nice teeth showing on top, two ptychodus on the sides, a fish vertebra, and some fish teeth showing. There might be a couple more shark teeth and lots of smaller fish teeth inside the rock. Check out my trip reports and you can see mo- 1 reply

Well, it's taken me a lot longer than I thought it would to write the second part of this trip report, mostly because I've been busy with school and several trips to other places across Texas collecting fossils, but also because I must have made about nine trips to the particular Eagle Ford formation creek site I wrote about in the first post. I've got a lot I could say, but I'll narrow it down to just the most exciting finds - I've still got another trip report covering two trips I took to Jacksboro/Mineral Wells and Post Oak Creek to write as soon as I'm done with this one! I'll

New Year’s Hunt- first finds of the year! (Ptychodus heavy!)
PaleoPastels posted a topic in Fossil Hunting Trips
Hey forum! No long story this time- it was New Years Day and I decided to hit up my special Eagle Ford spot off the beaten path to start the year off. That day was of my most productive creek crawling adventures in this specific spot yet! I’m already focused on pursuing my education goals this year as well. First: I want to show off my new exciting lucky shark tooth hunting shirt! I drew, on digital, “Prehistoric Sharks of Texas” and slapped it onto a tee. The tag is my autograph printed on the back of the neck which feels surreal! The teeth were hand-drawn by me over layers of- 6 replies

I need an expert's eye on this one . Looks like a fragment of an ptychodus shark tooth embedded in this sandstone. I didn't knew what I have until I posted it on a fossil group on Facebook and some experts told me that it is an ptychodus shark tooth fragment. It was found on beach at the gulf of kutch(65-2mya) late cretaceous-tertiary. I founded that this shark lived during the late cretaceous period and the sediments from where it was found dated the same age.

I found this Ptychodus marginalis on a sandbar on a river this spring after a large flood. The river cuts through the lower Smoky Hill Chalk of Northwest Kansas. After I picked it up, I asked myself "is this real?" It is!!! 54mm across.

This has to be a very brief report, as I have to hop in my car soon to go hunt for my ever elusive Pseudomegachasma tooth - but I discovered a tiny, amazing site on a scout this weekend: The trek had me running into several large homeless camps, so I was a little tense the entire time, but the results were worth it. All of these finds came from a sandstone roof above me. It was like looking up at a church ceiling mural, telling a story of some distant time, except this was a ~95 million year old story, of a seafloor frozen in time. For that reason, I named this site "The Sistine Ce

It's been over a month now since @Jared C and I found the Eagle Ford Xiphactinus. In the weeks that followed our discovery I was able to get in touch with the right people at Baylor University where I go to school and start to organize a retrieval project. Unfortunately I haven't been able to make it back to the site since then as all involved will have to wait for the wheels of bureaucracy to turn enough for us to have the proper permission necessary to return. So I was left with a problem: my first visit to the Eagle Ford turned out so well that I wanted nothing more than to go back, but I c

As it looks like I won't be able to make it back out to Charleston for quite a while, I was wondering what the fossil hunting scene looks like here in Texas. I've heard that there's some miocene material to be had around Galveston and Bolivar, and I've heard about the Eagle Ford Formation and Post Oak Creek, but I haven't come across a whole lot of information. I do know there are some invertebrate fossils along the Brazos, but I'm not super big on snails. I'm in the Houston area, so a day trip down to the coast is definitely feasible, but I need to do some more research before I commit to mak

Please identify this tooth Found in cretaceous, turonian sandy-limestone in Poland (Górka Pychowicka, Cracow). This rock is amazing, on left there's Ptychodus decurrens tooth too.
