Argana Group (Morocco)

The Argana Group is a Permian to Triassic geological group in the western High Atlas northeast of Agadir, Morocco. [1] Sometimes known as the Argana Formation, it contains eight geological members often divided into three formations. They include the Late Permian Ikakern Formation (members T1-T2), the Early Triassic to Carnian Timezgadiouine Formation (T3-T5), and the Late Triassic Bigoudine Formation (T6-T8). [2] Ornithischian tracks are geographically located in Marrakesh province. [2] Indeterminate theropod remains and tracks are geographically located in Marrakesh province. [2]

<i>Fabrosaurus</i> Extinct genus of ornithischian dinosaurs from the early Jurassic

Fabrosaurus is an extinct genus of plant-eating ornithischian dinosaur, it lived in the Early Jurassic during the Hettangian to Sinemurian stages 199 - 189 mya. It was originally placed within the now obsolete family Fabrosauridae.

<i>Azendohsaurus</i> Genus of herbivorous Triassic reptile

Azendohsaurus is an extinct genus of herbivorous archosauromorph reptile from roughly the late Middle to early Late Triassic Period of Morocco and Madagascar. The type species, Azendohsaurus laaroussii, was described and named by Jean-Michel Dutuit in 1972 based on partial jaw fragments and some teeth from Morocco. A second species from Madagascar, A. madagaskarensis, was first described in 2010 by John J. Flynn and colleagues from a multitude of specimens representing almost the entire skeleton. The generic name "Azendoh lizard" is for the village of Azendoh, a local village near where it was first discovered in the Atlas Mountains. It was a bulky quadruped that unlike other early archosauromorphs had a relatively short tail and robust limbs that were held in an odd mix of sprawled hind limbs and raised forelimbs. It had a long neck and a proportionately small head with remarkably sauropod-like jaws and teeth.

Breviparopus is the name given to an ichnogenus of dinosaur, having been made by an unknown genus of sauropod. As an ichnogenus, the taxon is represented by a 90-metre (295 ft) long series of fossil tracks, or ichnites, found in the spring of 1979 in the Atlas Mountains of present-day Morocco. At the time, this area would have been part of the splitting Gondwana supercontinent. The animal that produced the Breviparopus tracks is rumored to be one of the largest dinosaurs, though its exact size has been the subject of much debate.

<i>Metoposaurus</i> Extinct genus of amphibians

Metoposaurus meaning "front lizard" is an extinct genus of stereospondyl temnospondyl amphibian, known from the Late Triassic of Germany, Italy, Poland, and Portugal. This mostly aquatic animal possessed small, weak limbs, sharp teeth, and a large, flat head. This highly flattened creature mainly fed on fish, which it captured with its wide jaws lined with needle-like teeth. Metoposaurus was up to 3 m long and weighed about 450 kg. Many Metoposaurus mass graves have been found, probably from creatures that grouped together in drying pools during drought.

Arganasaurus is an extinct genus of prehistoric temnospondyl amphibian belonging to the family Metoposauridae that lived in Morocco during the Late Triassic (Carnian).

<i>Dutuitosaurus</i> Extinct genus of amphibians

Dutuitosaurus is a genus of metoposaurids, a group of amphibians that lived during the Late Triassic period. Dutuitosaurus was discovered in the early 1960s in Morocco and is known from the lower t5 units of the Timezgadiouine Formation exposures in the Argana Basin of the High Atlas Mountains and was first described in 1976 by French paleontologist Jean-Michel Dutuit. Material of Dutuitosaurus is currently held in the Muséum national d'histoire naturelle (MNHN) in Paris, France. It was originally placed within Metoposaurus as M. ouazzoui but was subsequently placed in its own genus, Dutuitosaurus, by Hunt (1993), who identified a number of differences between Metoposaurus and the Moroccan metoposaurids. Features that differentiate Dutuitosaurus from other metoposaurids include relative elongate intercentra and a maxilla that enters the orbit.

The Tilougguit Formation, also known as the Tillouguit Formation, is an Early Bathonian geologic formation in Morocco. An indeterminate sauropod is known from the formation

The Aganane Formation is a Pliensbachian geologic formation in the Azilal Province, central Morocco, know mostly for it´s rich Tracksites including footprints of Thyreophoran, Sauropod and Theropod Dinosaurs. This Formation has been age constraint to the Pliensbachian stage of the Lower Jurassic, thanks to the find of the ammonite Arieticeras cf. algovianum Indicator of Middle Domerian=Uppermost Pliensbachian) in the upper zone, and lower delimitation by the foraminifers Mayncina termieri & Orbitopsella praecursor. The Dinosaur tracksites are all located a few metres below the limit Pliensbachian-Toarcian, being coeval and connected with the lowermost layers of the continental Azilal Formation. The Aganane Formation was also coeval with the Jbel Taguendouft Formation and the Tamadout 1 Formation, all developed along a local "platform-furrow" in the Middle Atlas Mountains, that act as a barrier controlling the western border of the Jurassic Atlas Gulf. The nearshore sections, including both carbonate platforms and close to sea terrestrial facies where located on an isolated internal domain thanks to the control of the barrier, allowing the Aganane Formation to develop on a hot and humid climate, where a local algal marsh had intermitent progradations, intercalated with a layer of terrigenous continental origin. The Ichnosites where developed in tidal flats and coastal deposits suitable to sea floodings.

The Adoudounien is an obsolete geological stage used in North Africa to characterise stratigraphic formations located at the transition between the Ediacarian and the Cambrian. While largely used in the scientific literature in the 20th century and still common in articles related to the geology of Morocco, the definition of this unofficial term remains blurry and no start and end dates where associated to it.

Azilal Formation

The Azilal Formation, also known as Toundute Continental Series and Wazzant Formation, is a geological unit in the Azilal and Ouarzazate provinces of the High Atlas of Morocco that covers the Latest Pliensbachian 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 in the group have been considered individual in the past, a division of the so-called "Couches rouges", and subdivided by a supposed geological scale. The strata of the group extend towards the Central High Atlas, covering different anticlines and topographic accidents along the mountain range. However, new studies have suggested that the strata is coeval in age, and should be referred to as a unique unit. The formation is best considered an alluvial environment occasionally interrupted by shallow marine incursions and marks a dramatic decrease in carbonate productivity under increasing terrigenous sedimentation. The Azilal Formation consists mainly of claystones rich in continental plant debris and laminated microbial facies. The Toarcic High Atlas is divided into five units: the continental layers with paralic|paralic deposits belong to the Azilal, along the shoreface layers of the Tagoudite Formation and Tafraout Formation, both connected with the offshore Ait Athmane Formation and the deeper shelf deposits of the Agoudim 1 Formation.

Kholumolumo, formerly "Kholumolumosaurus" or "Thotobolosaurus", is an extinct genus of massopodan sauropodomorph dinosaur, which was closely related to Sarahsaurus, from the lower Elliot Formation of Maphutseng, Lesotho. The type species, Kholumolumo ellenbergerorum was formally described in 2020.

Rhynchosauroides is an ichnogenus, a form taxon based on footprints. The organism producing the footprints was likely a lepidosaur and may have been a sphenodont, an ancestor of the modern tuatara. The footprint consists of five digits, of which the fifth is shortened and the first highly shortened.

The Timezgadiouine Formation, sometimes spelled as the Timesgadiouine Formation, is a Triassic geological formation in the Argana Basin of Morocco. It is a succession of red bed sediments spanning from the Olenekian to at least the Carnian, encompassing members T3 to T5 of the Argana Group. It is preceded by the Permian Ikakern Formation and succeeded by the Late Triassic Bigoudine Formation.
