Prognathodon anceps vs. Prognathodon giganteus: What is the difference?
Praefectus posted a topic in General Fossil Discussion
I have been reading up on Moroccan mosasaurs and one point of confusion that I have run into is differentiating teeth from Prognathodon anceps and Prognathodon giganteus. There seems to be a great deal of overlap in their descriptions and occasional contradictions in the scientific literature. The first issue I’ve noticed is that there seems to be a great deal of confusion over what to even call the two species. Leiodon anceps (Owen, 1841-1845) was based on two tooth fragments and a section of jawbone. The genus was renamed Liodon by Agassiz (1846) because the- 10 replies

So I decided that I would finally make a point of documenting some of these back country field excursions, and made a Youtube channel to keep the videos all in one place. Here's a a rather ordinary extraction of a placenticeras ammonite found the day before we did a little field work with some paleontologists. The GoPro is a fun addition to my kit, and makes it a lot easier to document the actual process of finding and extracting these things in the field. Anyway, I'll let the video speak for itself - enjoy! (click the image to open video link)

The giant mosasaur Prognathodon is now known from Denmark!
The Amateur Paleontologist posted a topic in Fossil News
A paper was recently published announcing the presence of Prognathodon in the Late Cretaceous chalk of Denmark. Prognathodon was a large, predatory mosasaur, well-known in the USA and Morocco, but known from other places e.g., the Netherlands. This new study is especially quite a big deal, because mosasaur fossils are incredibly rare in the Danish chalks. Prognathodon is now the 4th mosasaur known from the Late Cretaceous of Denmark, along with Mosasaurus, Plioplatecarpus and Carinodens. The Danish material is represented by two teeth - one of them being from the foss- 1 reply

There is a new Moroccan Mosasaur described here: https://www.sciencedirect.com/science/article/abs/pii/S0195667121001294?via%3Dihub It is called Pluridens serpentis. I suspect pictures of it's skull may already have been shown on this thread under another identification. It is known from two skulls and mandibles.

Hello all, Found these really cool fossils (some weeks ago). The fossils are from the Cretaceous period (shallow marine environment covered Limburg - part of the Netherlands). The fossils are from the upper upper Campanian and lower Maastrichtien (73-69 and/or 72-69 and/or 72-68 mya). I and my girlfriend were searching for fossils and walking in a forest when we found two VERY LARGE echinoids (Echinocorys scutata (Leske, 1778). These are really big and the best ones I have in my collection (one is 9 a 10 cm). The other one is also really big, somewhat flatter,

From the album: Delaware Fossils
Vertebrae from either a stingray or skate. Found in close proximity to each other at a site where such things are rare, so probably from the same animal. L:arger one is about 3cm wide. Found at Reedy Point, C and D Canal, Delaware. Maastrichtian. -
Yesterday: fossil hunting with my girlfriend in Limburg. Many Cretaceous limestones and good fossil specimens! Including a really big and complete Pycnodonte vesicularis (Lamarck, 1806). My second biggest Pycnodonte. Many belemnites (including a real cool black one!), two pieces (including a big one) from the same genus (Pycnodonte) and one sea urchin Echinocorys sp. or Echinocorys scutata (Leske, 1778). Also one recent cow/bovid tooth and a piece of vase. The two photo's on the right are from another (earlier) trip (fossils are on the ground in a field. Finds: one sea

Last January 12, I found some Exogyra sp. oysters in a limestone Late Campanian / Early Maastrichtian strata (SE Pyrenees, Catalonia, Spain), who turned to show abundant beekite rings. I owe to @abyssunder my knowledge of this mineral phenomenon, which, in my area,occurs mainly over laminar-type shells like oysters' (It can occur on other fossils, though). Have you fossils with beekite rings ?

Morocco keeps delivering cool new discoveries. A new small Mosasaur is described in the attached publication, its Xenodens calminechari from the upper Maastrichtian phosphates of Morocco. Paywalled https://www.sciencedirect.com/science/article/abs/pii/S0195667121000112 Teeth form a unique dental battery in which short, laterally compressed and hooked teeth formed a saw-like blade. @jnoun11 Has anyone seen teeth like these or have them in their collection?

Late Cretaceous chalk in North America
The Amateur Paleontologist posted a topic in General Fossil Discussion
Hey everyone I know I've been lately rather inactive on TFF; I was held back by fieldwork and other reasons (though do expect some posts about the fieldwork next weekend ). But anyway, onto what I came to talk about... Would anyone know of some good exposures of Late Cretaceous chalk in Canada or USA? I'm thinking specifically about Campanian chalk or, even better, Maastrichtian chalk.. It would be great if the exposed chalk is very fossiliferous, of course. Thanks for any help! -Christian -

ziggycardon posted a topic in Europe
Hi everyone. I was hoping some of our European members might be able to help me out a little. I am currently at home due to depression, burn-out and severe anxiety attacks all related due to the COVID-19 situation (I work in a essential store and I belong to the risk groups, so after 6 months the stress finally became too much). Long story short, I haven’t left the house since march (except for work), the only 4 times I left was because I had to go to the doctor. But now I am at home and I am currently in therapy with a psychologist and the natural next step is to finally ventu -
The treasure of the Reedy Point Spoils is in the micros! This is one of over 100 micros I collected in one day just surface collecting after the spoils area was freshly cleared of vegetation -- and freshly cleared of much of the remaining matrix. Of all of those micro fossils, this is the only one of this species and very possibly the only one I have found in 16 years of collecting at that site. The Reedy Point Spoils is a 220+ acre dredge deposit from the Chesapeake and Delaware Canal. The matrix is a combination of material from the Mt Laurel and Navesink Formations, which are no

This topic is a short continuation of my previous topic on my Squalicorax collection, which can be seen here: This time I have chosen to show my Pseudocorax teeth. As with the Squalicorax teeth, I am open for trades and buying new additions. The oldest examples of Pseudocorax in my collection come from the Lower Campanian. Like the Squalicorax genus, they start off as a genus with very small teeth.

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

Hi everybody! Last month i saw this tooth on sale and it was love at first sight But from the beginning i understood that what it was and how it be presented are not on the same page... Luckily i know the seller pretty well and we trust each other...so i asked info before make the purchase...He told me that his provider (directly from Morocco) told him that the tooth was a Dyrosaurus phosphaticus but that he was not confident about the ID...the moroccan provider told to my friend/seller that was the first time that he saw a totth like that and its first idea of ID was D.

The first Hadrosauridae from the Maastrichtian of Morocco is described in this paper. Pretty cool, its a lambeosaurine called Ajnabia odysseus. From Ouled Abdoun Basin. Its also the first named hadrosaur from Africa. Hopefully will see some teeth on the market.
