Paul Emil von Lettow-Vorbeck, also called the Lion of Africa, was a general in the Imperial German Army and the commander of its forces in the German East Africa campaign. For four years, with a force of about 14,000, he held in check a much larger force of 300,000 British, Indian, Belgian, and Portuguese troops.
Kentrosaurus is a genus of stegosaurid dinosaur from the Late Jurassic of Tanzania. The type species is K. aethiopicus, named and described by German palaeontologist Edwin Hennig in 1915. Often thought to be a "primitive" member of the Stegosauria, several recent cladistic analyses find it as more derived than many other stegosaurs, and a close relative of Stegosaurus from the North American Morrison Formation within the Stegosauridae.
The osteon or haversian system is the fundamental functional unit of much compact bone. Osteons are roughly cylindrical structures that are typically between 0.25 mm and 0.35 mm in diameter. Their length is often hard to define, but estimates vary from several millimeters to around 1 centimeter. They are present in many bones of most mammals and some bird, reptile, and amphibian species.
Dryosaurus is a genus of an ornithopod dinosaur that lived in the Late Jurassic period. It was an iguanodont. Fossils have been found in the western United States and were first discovered in the late 19th century. Valdosaurus canaliculatus and Dysalotosaurus lettowvorbecki were both formerly considered to represent species of Dryosaurus.
Professor David Bruce Weishampel is an American palaeontologist in the Center for Functional Anatomy and Evolution at Johns Hopkins University School of Medicine. Weishampel received his Ph.D. in Geology from the University of Pennsylvania in 1981. His research focuses include dinosaur systematics, European dinosaurs of the Late Cretaceous, jaw mechanics and herbivory, cladistics and heterochrony and the history of evolutionary biology. Weishampel's best known published work is The Dinosauria University of California Press; 2nd edition. He consulted for Jurassic Park and is a good friend of Steven Spielberg. He has received an Academy Scientific and Technical Award.
Giraffatitan is a genus of sauropod dinosaur that lived during the late Jurassic Period. It was originally named as an African species of Brachiosaurus (B. brancai), but this has since been changed. Giraffatitan was for many decades known as the largest dinosaur but recent discoveries of several larger dinosaurs prove otherwise; giant titanosaurians appear to have surpassed Giraffatitan in terms of sheer mass. Also, the sauropod dinosaur Sauroposeidon is estimated to be taller and possibly heavier than Giraffatitan.
Dicronorhina derbyana is a sub-Saharan species of flower chafer.
Ostafrikasaurus is a genus of theropod dinosaur from the Late Jurassic period of what is now Tanzania. It is known only from fossil teeth discovered sometime between 1909 and 1912, during an expedition to the Tendaguru Formation by the Natural History Museum of Berlin. Eight teeth were originally attributed to the dubious dinosaur genus Labrosaurus, and later to Ceratosaurus, both known from the North American Morrison Formation. Subsequent studies attributed two of these teeth to a spinosaurid dinosaur, and in 2012, Ostafrikasaurus crassiserratus was named by French palaeontologist Eric Buffetaut, with one tooth as the holotype, and the other referred to the same species. The generic name comes from the German word for German East Africa, the former name of the colony in which the fossils were found, while the specific name comes from the Latin words for "thick" and "serrated", in reference to the form of the animal's teeth.
Mycerinodes is a genus of longhorn beetles of the subfamily Lamiinae, containing the following species:
Megalobrimus is a genus of longhorn beetles of the subfamily Lamiinae, containing the following species:
Mycerinodes puerilis is a species of beetle in the family Cerambycidae. It was described by Kolbe in 1894.
Mycerinodes uluguruensis is a species of beetle in the family Cerambycidae. It was described by Stephan von Breuning in 1975. It is known from Tanzania.
Megalobrimus lettowvorbecki is a species of beetle in the family Cerambycidae. It was described by Richard Kriesche in 1923. It is known from Tanzania.
Dinosaur teeth have been studied since 1822 when Mary Ann Mantell (1795-1869) and her husband Dr Gideon Algernon Mantell (1790-1852) discovered an Iguanodon tooth in Sussex in England. Unlike mammal teeth, individual dinosaur teeth are generally not considered by paleontologists to be diagnostic to the genus or species level for unknown taxa, due morphological convergence and variability between teeth. and many historically named tooth taxa like Paronychodon and Richardoestesia are today considered nomina dubia, and are used as form taxa to refer to isolated teeth from other localities displaced considerably in time and space from the type specimens. However, it is possible to refer isolated teeth to known taxa provided that the tooth morphology is known and the teeth originate from a similar time and place.
This article records new taxa of fossil archosaurs of every kind that are scheduled described during the year 2021, as well as other significant discoveries and events related to paleontology of archosaurs that are scheduled to occur in the year 2021.
The year 2018 in non-avian dinosaur archosaur paleontology was eventful. Archosaurs include the only living dinosaur group — birds — and the reptile crocodilians, plus all extinct dinosaurs, extinct crocodilian relatives, and pterosaurs. Archosaur palaeontology is the scientific study of those animals, especially as they existed before the Holocene Epoch began about 11,700 years ago. This article records new taxa of fossil archosaurs of the non-avian variety that have been described during the year 2018, as well as other significant discoveries and events related to paleontology of archosaurs that occurred in the year 2018.
