Bahariasaurus
''Bahariasaurus'' (meaning "Bahariya lizard") is an enigmatic genus of large theropod dinosaur. ''Bahariasaurus'' is known to have included at least 1 species, ''Bahariasaurus ingens'', which was found in North African rock layers dating to the Cenomanian and Turonian ages of the Late Cretaceous. The only fossils confidently assigned to ''Bahariasaurus'' were found in the Bahariya Formation of the Bahariya (Arabic: الواحة البحرية meaning the "northern oasis") oasis in Egypt by Ernst Stromer but were destroyed during a World War II bombing raid with the same raid taking out the holotype of ''Spinosaurus'' and ''Aegyptosaurus'' among other animals found in the Bahariya Formation. While there have been more fossils assigned to the genus such as some from the Farak Formation of Niger, these remains are referred to with much less certainty. ''Bahariasaurus'' is, by most estimations, one of the largest theropods, approaching the size of other large bodied theropods such as ...

Deltadromeus
''Deltadromeus'' (meaning "delta runner") is a genus of theropod dinosaur from Northern Africa. It had long, unusually slender hind limbs for its size, suggesting that it was a swift runner. The skull is not known. One fossil specimen of a single species (''D. agilis'', or "agile delta runner") has been described, found in the Kem Kem Beds, which date to the mid-Cretaceous Period (mid-Cenomanian age), about 95 million years ago. It may be a junior synonym of the contemporary ''Bahariasaurus''.Holtz, Thomas R. Jr. (2008) ''Dinosaurs: The Most Complete, Up-to-Date Encyclopedia for Dinosaur Lovers of All Ages'Supplementary Information/ref> The classification of ''Deltadromeus'' has been in flux since its original description. In 2016, a South American theropod known as ''Gualicho shinyae'' was found to possess many similarities with ''Deltadromeus''. Depending on the phylogenetic position of ''Gualicho'', ''Deltadromeus'' may have been a neovenatorid carnosaur, a tyrannosauroid, or ...

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 ...

Spinosaurus
''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] |
Carcharodontosauridae
Carcharodontosauridae (carcharodontosaurids; from the Greek καρχαροδοντόσαυρος, ''carcharodontósauros'': "shark-toothed lizards") is a group of carnivorous theropod dinosaurs. In 1931, Ernst Stromer named Carcharodontosauridae as a family, which, in modern paleontology, indicates a clade within Carnosauria. Carcharodontosaurids include some of the largest land predators ever known: ''Giganotosaurus'', ''Mapusaurus'', ''Carcharodontosaurus'', and ''Tyrannotitan'' all rivaled or exceeded ''Tyrannosaurus'' in size. A 2015 paper by Christophe Hendrickx and colleagues gives a maximum length estimate of for the largest carcharodontosaurids, while the smallest carcharodontosaurids were estimated to have been at least long. Evolution Along with the spinosaurids, carcharodontosaurids were the largest predators in the early and middle Cretaceous throughout Gondwana, with species also present in North America (''Acrocanthosaurus''), Europe (''Concavenator'') and Asia ...

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Albert-Félix De Lapparent
Albert-Félix de Lapparent (1905–1975) was a French palaeontologist. He was also a Sulpician priest. He undertook a number of fossil-hunting explorations in the Sahara desert. He contributed greatly to our knowledge of dinosaurs and other prehistoric creatures. In 1986, José Bonaparte named the dinosaur ''Lapparentosaurus'' in his honour. Dinosaurs named by Lapparent were ''Inosaurus tedreftensis'' (Lapparent, 1960) and '' Lusitanosaurus liassicus'' (Lapparent and Zbyszewski, 1957). New species of known genera are also credited to him. In alphabetical order, they are: '' Apatosaurus alenquerensis'' (Lapparent and Zbyszewski, 1957), '' Astrodon pusillus'' (Lapparent and Zbyszewski, 1957), '' Brachiosaurus atalaiensis '' (Lapparent and Zbyszewski, 1957), '' Brachiosaurus nougaredi'' (Lapparent, 1960), ''Cetiosaurus mogrebiensis'' (Lapparent, 1955), '' Elaphrosaurus gautieri'' (Lapparent, 1960), '' Elaphrosaurus iguidiensis'' (Lapparent, 1960), '' Megalosaurus pombali'' (Lapparent ...
