Aegyptosaurus
''Aegyptosaurus'' (meaning 'Egypt's lizard') is a genus of sauropod dinosaur that lived in what is now Africa, around 95 million years ago, during the Late Cretaceous Period (Cenomanian faunal stage). Discovery and naming The holotype (1912VIII61) consists of three caudal vertebrae, a partial scapula, and some limb bones, all of which were discovered in the Bahariya Formation of Egypt between 1910 and by Ernst Stromer and Richard Markgraf and the holotype was sent to Munich, Germany in 1915 to be studied at the same time the holotype of ''Spinosaurus aegyptiacus'' was described. ''Aegyptosaurus'' was described by German paleontologist Ernst Stromer in 1932, seventeen years after the holotype was sent to Munich,Stromer, E. (1932a) Ergebnisse der Forschungsreisen Prof. E.

Bahariya Formation
The Bahariya Formation (also transcribed as Baharija Formation) is a fossiliferous geologic formation dating back to the early Cenomanian, which outcrops within the Bahariya depression in Egypt, and is known from oil exploration drilling across much of the Western Desert where it forms an important oil reservoir.Weishampel, David B; et al (2004). "Dinosaur distribution (Late Cretaceous, Africa)." In: Weishampel, David B.; Dodson, Peter; and Osmólska, Halszka (eds.): The Dinosauria, 2nd, Berkeley: University of California Press. Pp. 604. . Extent The Bahariya Formation forms the base of the depression, the lower part of the enclosing escarpment and all of the small hills within. The type section for the formation is found at Gebel El-Dist, a hill at the northern end of the Bahariya depression. Stratigraphy and sedimentology Four depositional sequences have been recognised in the Bahariya Formation in the Bahariya depression, separated by three sub-aerial unconformities. Th ...

Ernst Stromer
Ernst Freiherr Stromer von Reichenbach (12 June 1871 in Nürnberg – 18 December 1952 in Erlangen) was a German paleontologist. He is best remembered for his expedition to Egypt, during which the first known remains of ''Spinosaurus'' were discovered. He described the following Cretaceous dinosaurs from Egypt: ''Aegyptosaurus'', ''Bahariasaurus'', '' Carcharodontosaurus'', and the enigmatic theropod, ''Spinosaurus aegyptiacus''. Stromer also described the giant crocodilian, ''Stomatosuchus''. The fossil bird genus ''Stromeria'' (now included in the genus ''Eremopezus'') and the sauropod ''Paralititan stromeri'' were named in his honor (by Kálmán Lambrecht in 1929 and Smith et al. 2001,Smith JB, Lamanna MC, Lacovara KJ, Dodson P, Smith JR, Poole JC, Giegengack R, Attia Y (June 2001).

Richard Markgraf
Richard Markgraf (13 March 1869 – January or February 1916) was a German Bohemian paleontologist. He is best remembered for his expeditions to Egypt, which discovered the first known remains of many extinct fossil reptiles, such as ''Aegyptosaurus'' and ''Spinosaurus''. Biography Richard Markgraf was born in Přísečnice, Austria-Hungary (now the Czech Republic) on 13 March 1869 and he became a bricklayer before joining one of the travelling Preßnitz music groups until he eventually ended up impoverished in Cairo, Egypt, working as a pianist in the Shepheard's Hotel. He eventually met the German palaeontologist Eberhard Fraas in 1897 who hired him because of his knowledge of Arabic and he taught Markgraf the basic techniques of fossil hunting; he subsequently worked as a collector for Fraas. Markgraf eventually met Ernst Stromer during the winter of 1901–1902 and the two got along very well. Markgraf was Stromer's ''Sammler'', or fossil collector, for 10½ years, and beca ...

Titanosaurs
Titanosaurs (or titanosaurians; members of the group Titanosauria) were a diverse group of sauropod dinosaurs, including genera from all seven continents. The titanosaurs were the last surviving group of long-necked sauropods, with taxa still thriving at the time of the extinction event at the end of the Cretaceous. This group includes some of the largest land animals known to have ever existed, such as ''Patagotitan''—estimated at long with a weight of —and the comparably-sized ''Argentinosaurus'' and ''Puertasaurus'' from the same region. The group's name alludes to the mythological Titans of ancient Greek mythology, via the type genus (now considered a ''nomen dubium)'' ''Titanosaurus''. Together with the brachiosaurids and relatives, titanosaurs make up the larger sauropod clade Titanosauriformes. Titanosaurs have long been a poorly-known group, and the relationships between titanosaur species are still not well-understood. Description Titanosauria have the largest ran ...

Continental Intercalaire
The Continental intercalaire, sometimes referred to as the Continental intercalaire Formation, is a term applied to Cretaceous strata in Northern Africa. It is the largest single stratum found in Africa to date, being between thick in some places. Fossils, including dinosaurs, have been recovered from this formation. Weishampel, David B; et al. (2004). "Dinosaur distribution (Early Cretaceous, Africa)." In: Weishampel, David B.; Dodson, Peter; and Osmólska, Halszka (eds.): The Dinosauria, 2nd, Berkeley: University of California Press. Pp. 571-573. . The Continental intercalaire stretches from Algeria, Tunisia and Niger in the west to Egypt and Sudan in the east.

Spinosaurus Aegyptiacus
''Spinosaurus'' (; ) is a genus of spinosaurid dinosaur that lived in what now is North Africa during the Cenomanian to upper Turonian stages of the Late Cretaceous period, about 99 to 93.5 million years ago. The genus was known first from Egyptian remains discovered in 1912 and described by German palaeontologist Ernst Stromer in 1915. The original remains were destroyed in World War II, but additional material came to light in the early 21st century. It is unclear whether one or two species are represented in the fossils reported in the scientific literature. The best known species is ''S. aegyptiacus'' from Egypt, although a potential second species, ''S. maroccanus'', has been recovered from Morocco. The contemporary spinosaurid genus ''Sigilmassasaurus'' has also been synonymized by some authors with ''S. aegyptiacus'', though other researchers propose it to be a distinct taxon. Another possible junior synonym is ''Oxalaia'' from the Alcântara Formation in Brazil. ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cenomanian
The Cenomanian is, in the ICS' geological timescale, the oldest or earliest age of the Late Cretaceous Epoch or the lowest stage of the Upper Cretaceous Series. An age is a unit of geochronology; it is a unit of time; the stage is a unit in the stratigraphic column deposited during the corresponding age. Both age and stage bear the same name. As a unit of geologic time measure, the Cenomanian Age spans the time between 100.5 and 93.9 million years ago (Mya). In the geologic timescale, it is preceded by the Albian and is followed by the Turonian. The Upper Cenomanian starts around at 95 Mya. The Cenomanian is coeval with the Woodbinian of the regional timescale of the Gulf of Mexico and the early part of the Eaglefordian of the regional timescale of the East Coast of the United States. At the end of the Cenomanian, an anoxic event took place, called the Cenomanian-Turonian boundary event or the "Bonarelli event", that is associated with a minor extinction event for marine spec ...
