Hi TFF, Last week the GF and I went for the holy trio (geological wise ), the turonian, cenomanian and albian. It's simply amazing that in a relatively short stretch of cliffs you can find all three. Driving our way there it seemed like the UK also had some decent weather that day as it was quite visible. We first hit the turonian. On the way there you can find santonian(?) deposits which produce some nice flint urchins. I'm usually looking for big ammonites like lewesiceras or mammites. Only two small examples were found that we did not take home. In

Fossil hunting weekend to Falaises des Vaches Noires (Jurassic of France) + museum visit
ziggycardon posted a topic in Fossil Hunting Trips
Hi everyone! Last week we went on a weekend trip with our fossil club the BVP to go on a fossil hunt to the jurassic clay cliffs "Falaises de Vaches Noires" between Houlgate & Villers-Sur-Mer in Normandy, France. https://www.paleontica.org/locations/fossil/68 The famous cliffs of Vaches Noires date back to the Jurassic period, and span both the Callovian & Oxfordian stages (166 - 157 mya) and the Cretaceous period spanning the Cenomanian (100 - 94 mya). Back in the jurassic this area was a rich marine environment and fossils that can be found here are man- 30 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

The Kem Kem Beds are full of poorly understood Dinosaurs but the isolated material that wind up in collections are beautiful. The Beds consist of three formations: Ifezouane, Aoufous and Akrabou. I believe the first one is your primary Dinosaur producing layer in the Cenomanian age. The teeth that we see bombarding us at shows and online give us clues to the spectacular dinosaurs that roamed that region. Claws give us another perspective and by associating them to other regions we obtain more hints of what they looked like. A Dinosaur that no one needs introduction is Spinosaurus. I

Last weekend was an extended weekend and good weather forecast, that means a few field trips to the French coast for us The first trip was Friday, we got there early in the morning and planned to hunt the Turonian part of the coast. There was a lot of sand on the beaches so we didn’t find much, but quality is better than quantity and Natalie scored 2! Ptychodus teeth. I only found an ammonite that proved to be incomplete after extracting it :/ and a flint echinoid on the way back to the car. On Monday we tried our luck in the Cenomanian and Albian part of the site. Again lots o

Here are some of my finds from spending a few hours on Wednesday, October 26th, in the Graysonites wacoense Zone of the Grayson Formation, Washita Group of north Texas (Early Cenomanian, ~97mya). This particular site exposes a micromorph layer full of thousands of tiny dwarfed Mariella bosquensis and M. rhacioformis ammonites plus a wealth of other taxa like various urchins, brittlestar fragments, shark teeth, many gastropods & pelecypods, etc. Those familiar with the Del Rio exposures of further south in central Texas (particularly the now closed-to-public Waco Pit in McLennan County), sh

Teeth, Ammonites, and Crabs: A Day in the Upper Britton of North Texas
Aidan Campos posted a topic in Fossil Hunting Trips
On Wednesday, October 12th, I took another trip to a nearby favorite spot of mine that I found a few years ago which exposes the Sciponoceras gracile Zone, Camp Wisdom Member, Upper Britton Formation of the Eagle Ford Group here in Texas (Late Cenomanian-Early Turonian, 92-95mya), and had probably my best hunt from this site, including several different ammonites, a few shark teeth, my first Enchodus, and 26 Ferroranina dichrous crabs! First find was this very nice Yezoites delicatulus (Scaphitidae) ammonite A very worn Ptychodus sp. (Ptychodontidae) shark tooth:- 5 replies

Hello to all forum users! Glad to join you. I would like to share photos of some of my findings. Now there is an opportunity to post only a small part - the topic will be gradually supplemented. So, the finds of marine reptiles from the Cenomanian of the Cretaceous period of Ukraine. Several photos of the crown of the Ichthyosaurus tooth.

This last weekend produced probably the best results I've ever experienced while fossil hunting - these last two days will be hard to beat. Before I get to that though, I do want to include a find from the weekend before (since this is the topic of rarity). It was a local find and a first for the species for me. Not only that, but my first real "heartbreaker". It was bound to happen at some point! Sticking halfway out of the gravel, I instantly recognized a large Ptychodus tooth, of either P. marginalis or P. polygyrus - I couldn't remember at the time which of the two

Two trips, some amazing fossils, and a note to the forum (Middle August, 2022)
Jared C posted a blog entry in Trip Reports
Recently, my good friend Carter ( @Jackito ) found my personal holy grail of Texas Cretaceous sharks - Pseudomegachasma comanchensis While I knew of the existence of the genus here in Texas, I didn't know much about the teeth themselves as I never was really that convinced I'd ever find one. But Carter's find proved it's possible, and what's better... he found it at a site we both knew of! So, we went out together in an effort to find another. What's better is that I had suspicions about that site's age for a while, and the finding of his tooth attests to the late cen- 2 comments

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

Fairly recent bit of opal fossil research
The Amateur Paleontologist posted a topic in General Fossil Discussion
After learning about Weewarrasaurus, I thought it'd be nice to report the 'lesser-known' recent bit of research about the opalised fossil site Lightning Ridge (New South Wales, Australia) It's basically the most up-to-date paper dealing with the geology - including age, stratigraphy and lithology - and vertebrate paleontology. The paper provides many new details about the Griman Creek Formation (GCF), a Cenomanian (mid-Cretaceous) formation which crops out in the area around Lightning Ridge. The GCF is a formation especially known for its diverse vertebrate paleo-ecosystem; of which many spec- 6 replies

I acquired the tooth below a little over a year ago along with some Cretodus crassidens teeth from a Texas collector. They're from a Dallas County, Texas, site that exposes a buffer zone between the Eagle Ford and Woodbine Formations (Cenomanian-Turonian). All of the teeth were identified to me as Cretodus, and that appears to be correct for the others, but I'm pretty sure the ID on this one is incorrect. On further examination, it appears to be a cardabiodontid, though I'm not sure whether Dwardius or Cardabiodon. The slant length is just under 39 mm. @ThePhysicist @siteseer, you

We know very little about the bones of the Carcharodontosaurids in the Kem Kem Group. Here is a paper of a new Carcharodontosaurid from Argentina that is somewhat closely related that we can use to compare bones against.

Hello all I recently bought a tooth from the Kem Kem beds that clearly belongs to the genus Onchopristis. The weird thing about the tooth is that it has two hooks instead of just one. I know the species Onchopristis dunkeli has two (or more) hooks, but I don't find any official rapports metioning them in the Kem Kem beds. The tooth has yet to arrive, but I already wanted to ask the question. What do you think? Is there a chance O. dunkeli occurs in the Kem Kem beds or would it just be a pathological example. I have been searching a long time for a specimen like this. The toot

In lower Cenomanian the strange Ammonite "Mantelliceras" occurs. When you go to "Teutoburger Wald Area" in the north and north-east they are grey and compressed. I will post some over time. In the south, Haarstrang-Region and Ruhrgebiet, they can be very very nice, like this unusual white Mantelliceras dixoni, size is around 6 cm-

Last weekend we have been to the coast of France to look for fossils in the chalk. We found the usual ammonites, but I also saw some fish remains sticking out of a boulder. At first I thought to leave it since it looked very brittle. Natalie convinced me to take my time to try to extract it. She put some paraloid on it in the field and I removed the fossil with a knife. At home she consolidated the matrix and prepped the piece. She sure was right to take the fossil home , it turned out to be a really nice Enchodus Jaw.
