Hi all, it's been a minute since I've written a report and I think I'm due To start: This last January I got to be a part of two special discoveries in the marine reptile realm. Though not made directly by me, I'm still glad I got to be there. I'll detail them below: Early January: Last summer, I spent two weeks in North Dakota on the Hell Creek formation, and made some lifelong friends. Two of them (Harry and Piper) arranged a trip down from North Dakota and Florida, respectively, upon the discovery of cheap flight tickets, with the intent of catching up and taki

Unbelievable pterosaur diversity in this part of North Africa. This paper describes a unique small, long-beaked pterosaur from the Kem Kem Group of Morocco. Does not appear to be named. Paywalled https://www.sciencedirect.com/science/article/abs/pii/S0195667120303293

Is this really a mosquito, does anyone know it's taxonomy and does someone know the same for the spider ? This one looks like a genuine amber

Some Say Lightning Doesn't Strike the Same Place Twice...
EPIKLULSXDDDDD posted a topic in Fossil Hunting Trips
Return to the Badlands of North Texas At long last, rain graced the lands of North Texas this past week. For many of us, that meant it was time to finally crawl out of bed and beat the crowd to that one particular site desperately needing a refresh. In my case, I set on my way to explore a newer spot in the Grayson Marl while the ground was still nice and muddy. I'd been to this place once before, but it had already been thoroughly picked over. It's a popular site, but even then, it managed to pull through and produce some fine specimens for me to take home. With that in mind, I su- 8 replies

Here's a tooth I bought at the gem show back in the days when Moroccan vertebrate stuff was starting to appear at Tucson and other shows. I've been meaning to show it to people for years. It's from the Kem Kem Beds (Cenomanian), Taouz area, Morocco. It's about 61mm long with cutting edges that appear to be slightly crenulated rather than finely-serrated. It's oval in cross-section on the root end but the crown becomes blade-like toward the tip so it is somewhat labiolingually compressed. I assume it's a crocodile tooth but thought it might have a small chance at being from a di

Here's a specimen bought at the gem show back in the days when Moroccan vertebrate stuff was starting to appear at Tucson and other shows. It's from the Kem Kem Beds (Cenomanian), Taouz area, Morocco like that other crocodile-like tooth I showed here several days ago.. This one is just under 2 3/8 inches (59mm) long with long folds/ridges of what appears to be enamel along its length so I think it's a tooth. Some of the folds end part of the way to the tip. There are spots where these folds are chipped revealing a rather smooth layer. It shows wear at the tip. I think it's so

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
