Species

Haematosaurus is an extinct genus of teleosaurid thalattosuchian. Fossils have been found from Boulogne-sur-Mer in northern France of Jurassic age. [1] It was originally thought to be a plesiosaur, and the type species was initially assigned to the genus Plesiosaurus in 1874, although it was later reassigned to the new genus in 1934. [2] [3] It is now known to have been a marine crocodylomorph. [4] Due to the fragmentary nature of the material associated with the genus, it is currently regarded as a nomen dubium .

Liopleurodon is a genus of large, carnivorous marine reptile belonging to the Pliosauroidea, a clade of short-necked plesiosaurs. The two species of Liopleurodon lived from the Callovian Stage of the Middle Jurassic to the Kimmeridgian stage of the Late Jurassic Period. It was the apex predator of the Middle to Late Jurassic seas that covered Europe. The largest species, L. ferox, is estimated to have grown up to 6.4 metres (21 ft) in length.

<i>Cetiosaurus</i> genus of sauropod dinosaur

Cetiosaurus meaning 'whale lizard', from the Greek keteios/κήτειος meaning 'sea monster' and sauros/σαυρος meaning 'lizard', is a herbivorous sauropod dinosaur from the Middle Jurassic Period, living about 167 million years ago in what is now Europe.

<i>Teinurosaurus</i> genus of reptiles (fossil)

Teinurosaurus is a genus of carnivorous theropod dinosaur. Teinurosaurus lived during the Late Jurassic in what is now Portugal. The type species is Teinurosaurus sauvagei. It's been estimated to be 11.4 m in length and 3.6 tonnes in weight.

Morinosaurus was a genus of sauropod dinosaur from an unnamed formation of Kimmeridgian-age Upper Jurassic rocks from Boulogne-sur-Mer, Départment du Pas-de-Calais, France. It is an obscure tooth genus sometimes referred to the Lower Cretaceous English wastebasket taxon Pelorosaurus.

<i>Neosodon</i> genus of reptiles (fossil)

Neosodon was a genus of sauropod dinosaur from the Late Tithonian-age Upper Jurassic Sables et Gres a Trigonia gibbosa of Départment du Pas-de-Calais, France. It has never been formally given a species name, but is often seen as N. praecursor, which actually comes from a different animal. Often in the past, it had been assigned to the wastebasket taxon Pelorosaurus, but restudy has suggested that it could be related to Turiasaurus, a roughly-contemporaneous giant Spanish sauropod. It is only known from six teeth.

Erectopus is a basal allosauroid theropod from the Lower Cretaceous of France.

<i>Machimosaurus</i> Genus of reptiles

Machimosaurus is an extinct genus of teleosaurid crocodyliform from the Late Jurassic and Early Cretaceous. The type species, Machimosaurus hugii, was found in Switzerland. Other fossils have been found in England, France, Germany, Portugal, Switzerland and Tunisia. Machimosaurus rex is the largest named teleosaurid and thalattosuchian, with an estimated length of approximately 7.2 metres ,. Machimosaurus is the largest known crocodyliform of the Jurassic.

Azilal Formation

The Azilal Formation, also known as Toundute Continental Series and Wazzant Formation, is a geological unit in the Azilal & Ouarzazate provinces of the High Atlas of Morocco, that cover the middle Toarcian to early Aalenian stages of the Jurassic Period. It is a terrestrial deposit which overlies marine dolomites of equivalent age to the Budoš Limestone of Montenegro or the Marne di Monte Serrone of Italy. Dinosaur remains, such the Sauropod Tazoudasaurus and the Basal Ceratosaur Berberosaurus are known from the unit, along with several undescribed genera. The Units inside the group have been considered individual on the past, being a division of the so-called "Couches rouges", and subdivided by a supposed geological scale. The strata of the group extends towards the Central High Atlas, covering different anticlines, and topographic accidents along the range of the Mountains. Although new studies have suggested that the strata is coeval in age, and should be referred to as a unique unit. The Group is believed to have been a mostly deltaic, and river channels filled a succession of seashore and inland environments, covering the late Liassic coast of modern northern Africa. Based on observed halokinetic strata, the Tazoult Ridge evolved as a Salt Wall forming a 20 km long NE-SW trending structural and sedimentary high for at least 20 million years, between Pliensbachian-Bajocian periods. This emerged small landmass generated a great local Diapir, with continuous Diapirism until the end of the Aalenian.
