Όμορφος Halisaurus arambourgi (μοσάσωρας) Δεξί μερικό άνω γνάθου - Όψιμη Κρητιδική - Απολιθωμένα δόντια

Scientific name: Halisaurus aramborgi (Bardet et al., 2004) - Mosasaur Partial Right Maxillary

Location: Oued Zem, Morocco

Geological Formation: Ouled Abdoun Basin (Phosphate beds)

Age: Upper Cretaceous, Maastrichtian stage, (~66 Million Years)

Size: 49,7mm

REF.: #S265

DESCRIPTION:

Top beautiful partial right maxillary with 3 teeth (part of the posterior right maxilla) still preserved in its natural phosphatic matrix. It only has a few small fractures that have been glued and lightly filled, mainly on one of the teeth. But overall, it's a really good specimen. A great example of the dentition of this small lovely mosasaur species.

In the international market is very common to find Mosasaur fossils coming from the Late Cretaceous phosphate quarries of the Ouled Abdoun Basin (Central Morocco).

This quarries have been exploited since the beginning of the past century. Many sellers that sell this fossils do not make a good precise taxonomic identification work.

In these sites there are numerous different genus and species of Mosasaurs described in the enormous assemblage of giant marine reptiles that reigned the seas during the Cretaceous.

The main rich levels in these paleontological taxons are in the deeper stratigraphic levels of the sedimentarian filling of the Ouled Abdoun Basin. The age of these correspond to the Maastrichtian stage, 66 million years ago.

Most of the research carried out on these marine reptiles from Morocco have been performed by French researchers.

Next we list the different Mosasaur species which have been recognised in the phosphate rocks in North Africa:

-Halisaurus aramborgi (Bardet et al., 2005)
-Halisaurus walkeri (Lingham-Solier, 1998)

Longrich et al., 2022
-Prognathodon anceps (Leiodon anceps) - NOW †Thalassotitan atrox
Longrich et al., 2022
-Prognathodon solvay (Dollo, 1889)
-Prognathodon currii (Christiansen & Bonde, 2002)
-Eremiasaurus heterodontus (LeBlanc et al., 2012)
-Mosasaurus beaugei (Arambourg, 1952)
-Mosasaurus hoffmanni (Mantell, 1829)
-Tylosaurus (Marsh, 1872)
-Platecarpus ptychodon (Arambourg, 1954) - NOW Gavialimimus almaghribensis, sp. nov,2020
-Globidens phosphaticus (Bardet et al., 2005)
-Carinodens belgicus (Bardet et al., 2005)

The Ouled Abdoun Basin (or Khouribga Basin), located in the central sector of Morocco, is an enormous sedimentarian basin represented mostly by a vast filling of phosphate sediments. Apart from having a relevant raw material to be extracted, it has a series of very important paleontological sites in which amazing assemblages from big and small marine vertebrates are present. The basin has a so great continuity in its stratigraphic record that both the Upper Cretaceous as well as the two first epochs of the Paleogene (Paleocene and Eocene) can be studied.

The main assemblage of vertebrate fossils of the Paleogene sector present there is composed by sharks, fish, turtles, marine snakes, rays, crocodiles, other types of reptiles and even birds. In the Cretaceous part we can add Mosasaurs, Pterosaurs and Plesiosaurs, including some rare Theropod Dinosaurs as a new Abelisaurid (Chenanisaurus barbaricus), as well as one Hadrosaurid (Ajnabia odysseus). Also present in the Cretaceous a huge diversity of sharks and fishes.
