I would like to know the approximate age of the fossilized Great White teeth pictured in my hand that I have found over the course of the last 9 months at Holden Beach North Carolina. (since August of 2022) These were found in addition to many other fossilized teeth that I have captured in additional pictures found below. Thank You

Sharks of Same Era - Goblin and Crows - Any bigger species at that time?
Skeetersaurus posted a topic in Questions & Answers
Been a minute since posting but here's my question: I have found many Crow (squalicorax) and Goblin (Mitsukurina owstoni) teeth in a particular area and was wondering if I could expect any larger shark teeth to be found in the same immediate area? Any info is appreciated ☺️ ><^;>- 2 replies

From the album: Texas Turonian (Cretaceous)
Squalicorax cf. falcatus Turonian Texas Variation within Squalicorax falcatus. Since they all came from the same locality, odds are overwhelmingly favorable that they all represent the exact same taxon. Squalicorax exhibits great variation within the same species, and, of course, by tooth position in the mouth.-

Discovering the Kamp Ranch Limestone: Ptychodus Frenzy
EPIKLULSXDDDDD posted a topic in Fossil Hunting Trips
This month I decided to take on the challenge of finding my first Kamp Ranch sites. It's not the easiest thing to do since, to my knowledge, the elusive layer is not mapped anywhere. I spent a lot of time scouring the waterways of North Texas and by the end, I came up with two distant potential spots for a couple days worth of hunting. I traveled to the first site one sunny morning and after a long walk, I finally made it to the water's edge where I met endless limestone slabs filled with Collignoniceras woollgari impressions, meaning I was just in the right place. I readied my roc- 7 replies

I think North Texans will relate when I say that now and then, the urge to take a drive out to the NSR and spend the day hunting some Campanian gravel bars can spontaneously take complete hold. I had one of those moments just after the series of heavy rains and powerful winds our region encountered some days ago. Previously, my luck with weather at the NSR had been rather poor. Each time, the temps were either nearing a hundred degrees or only just above freezing, making a full on adventure crossing muddy waters and crawling atop unshaded gravel beds too much to handle. I had yet to experience

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

On Wednesday, November 30th, I took yet another trip to my micromorph spot in the Graysonites wacoense Zone of the Grayson Marl Formation, Washita Group of north Texas (Lower Cenomanian, ~97mya), laterally equivalent to the Waco Pit in the Del Rio Fm. further south. This time I focused mainly on looking for shark teeth which was a massive success, and I ended up finding a few new species to add to my faunal list for this location as well. The first find of the day was this nice small lateral Cretalamna catoxodon (Otodontidae) shark tooth, the most common shark species at this site:- 22 replies

A Day of Micromorph Ammonites, Shark Teeth, and Urchins in the Grayson Marl Formation of North Texas
Aidan Campos posted a topic in Fossil Hunting Trips
Here are just some of my finds from a day spent in the Graysonites wacoense Zone, Grayson Marl Formation, Washita Group of north Texas (Lower Cenomanian, ~97mya) last Sunday, November 13th. This is my second visit to the site, which is equivalent to and faunally almost identical to the Del Rio micromorph exposures of further south, today only present at a couple sites in the DFW area. Starting off with the first find which happened to be my first complete (sans spines and Aristotle’s lantern of course), and largest Goniophorus scotti (Goniophoridae) urchin:- 10 replies

Recently got back from a trip on Holden Beach, and just WOW. Words can't describe the uniqueness of being able to find Mosasaur teeth next to Megalodon teeth. The recent Hurricane brought in many new fossils and I had quite good luck. Here are some photos of the trip, I will post a picture showing all of my best finds shortly, but for now enjoy! First, here are some of the Squalicorax pristodontus teeth I collected. These were relatively common.

a nice find of Squalicorax with verts from the german campanian
rocket posted a topic in Fossil News
Year ago two friends of mine found some nice teeth and vertebraes from Squalicorax. As they were found close together - what is very unusual - we decided to write a small paper about it. We came to the solution that the verts and teeth belong to the skull-region of the shark. Finds like this are very rare, not many published till now. Journal was "APH" (www.ap-h.de), founded in Hannover. A nice Paper (now existing 50 Years!), 4 issues a year full of papers about northern germany fossils and more 49-61 (Raquet).pdf- 2 replies

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

WOW, what a day! Today I had the pleasure of finally meeting @Jared C after over a year of reading his trip reports and admiring all of the incredible finds he's made exploring the Cretaceous formations of Central Texas. We have a lot in common: both of us are pursuing a career in paleontology, are both (almost) the same age, and are both attending universities in-state that are only an hour and a half away from each other. Needless to say, I can't believe it took us this long to finally go on a hunt together. Jared drove up from his new place in College Station this morning to me

Looking for Ptychodus and Squalicorax teeth
Meganeura posted a topic in Member Fossil Trades Bulletin Board
Hey everyone! I’m looking to trade various Florida fossils such as Lemon shark, Carcharhinus, Tiger, and Hemipristis Serra teeth, soft shelled turtle shell, sting Ray mouth plates and barbs, etc. for a Ptychodus or a Squalicorax tooth! Feel free to send me a message if you want pictures or have requests! -
From the album: Sharks
Just a handful of Cretaceous species, most from North Texas. The sea that bisected North America ~85 million years ago played host to a diverse and burgeoning ecosystem that supported many species of sharks. It was likely due to specialization that allowed these sharks to all live in the same place and time. -

Reconstructed tooth set from a "Crow" shark - Squalicorax (could be S. falcatus) - illustrating the variety of tooth positions. Anterior teeth have erect, triangular cusps. Lateral teeth and posteriors are more common and have an increasingly posteriorly slanted crown, resembling the teeth of modern tiger sharks. -

Hello forum members! With the new Coronavirus raging across the world, I thought it would be nice to start some kind of advent calendar, using my own Squalicorax collection. Everyday I will post one or multiple Squalicorax teeth from one location. Let's see what ends sooner, my collection or the virus outbreak. I will start with the oldest tooth from the Albian substage and end with the teeth from the uppermost substage; the Maastrichtian. The first one is the oldest and also one of the smallest teeth in my collection. Unfortunately it is so sma
