Veterupristisaurus Milneri
''Veterupristisaurus'' is an extinct genus of carcharodontosaurid theropod dinosaur known from the Jurassic of Tendaguru, Lindi Region of southeastern Tanzania. Discovery and naming ''Veterupristisaurus'' is known from the holotype specimen MB R 1938, an isolated middle caudal vertebra. Two partially fused posterior middle caudal vertebrae, MB R 2166, from the same locality as the holotype, are referred to this genus and most probably came from the same individual. The anterior caudal vertebra, MB R 1940, may also represent this genus. The holotype was collected in the St (EH) locality of the Tendaguru in German East Africa, from the Middle Dinosaur Member of the Tendaguru Formation, dating to the late Kimmeridgian to earliest Tithonian faunal stage of the Late Jurassic, about 154-150 million years ago. The holotype was originally referred to ''Ceratosaurus? roechlingi'' by Werner Janensch in 1925. ''Veterupristisaurus'' was named by Oliver W ...

Late Jurassic
The Late Jurassic is the third epoch of the Jurassic Period, and it spans the geologic time from 163.5 ± 1.0 to 145.0 ± 0.8 million years ago (Ma), which is preserved in Upper Jurassic strata.Owen 1987. In European lithostratigraphy, the name "Malm" indicates rocks of Late Jurassic age. In the past, ''Malm'' was also used to indicate the unit of geological time, but this usage is now discouraged to make a clear distinction between lithostratigraphic and geochronologic/chronostratigraphic units. Subdivisions The Late Jurassic is divided into three ages, which correspond with the three (faunal) stages of Upper Jurassic rock: Paleogeography During the Late Jurassic Epoch, Pangaea broke up into two supercontinents, Laurasia to the north, and Gondwana to the south. The result of this break-up was the spawning of the Atlantic Ocean. However, at this time, the Atlantic Ocean was relatively narrow. Life forms of the epoch This epoch is well known for many famous types of dinosau ...

German East Africa
German East Africa (GEA; german: Deutsch-Ostafrika) was a German colony in the African Great Lakes region, which included present-day Burundi, Rwanda, the Tanzania mainland, and the Kionga Triangle, a small region later incorporated into Mozambique. GEA's area was , which was nearly three times the area of present-day Germany and double the area of metropolitan Germany at the time. The colony was organised when the German military was asked in the late 1880s to put down a revolt against the activities of the German East Africa Company. It ended with Imperial Germany's defeat in World War I. Ultimately GEA was divided between Britain, Belgium and Portugal and was reorganised as a mandate of the League of Nations. History Like other colonial powers the Germans expanded their empire in the Africa Great Lakes region, ostensibly to fight slavery and the slave trade. Unlike other imperial powers, however they never formally abolished either slavery or the slave trade and preferre ...

Bipedal
Bipedalism is a form of terrestrial locomotion where an organism moves by means of its two rear limbs or legs. An animal or machine that usually moves in a bipedal manner is known as a biped , meaning 'two feet' (from Latin ''bis'' 'double' and ''pes'' 'foot'). Types of bipedal movement include walking, running, and hopping. Several groups of modern species are habitual bipeds whose normal method of locomotion is two-legged. In the Triassic period some groups of archosaurs (a group that includes crocodiles and dinosaurs) developed bipedalism; among the dinosaurs, all the early forms and many later groups were habitual or exclusive bipeds; the birds are members of a clade of exclusively bipedal dinosaurs, the theropods. Within mammals, habitual bipedalism has evolved multiple times, with the macropods, kangaroo rats and mice, springhare, hopping mice, pangolins and hominin apes ( australopithecines, including humans) as well as various other extinct groups evolving the ...

Angela Milner
Angela Cheryl Milner (3 October 1947 – 13 August 2021) was a British Paleontology, paleontologist who, in 1986 alongside Alan Charig, described the dinosaur ''Baryonyx''. Early life Milner was born Angela Girven in Gosforth, daughter of Cyril and Lucia Girven. Her father was the county engineer for Northumberland. She attended Newcastle upon Tyne Church High School, Church High school. She initially planned to focus on microbiology for her university degree, but inspiring lectures from Alec Panchen made her change to palaeontology. She gained a Bachelor of Science, BSc in zoology at Newcastle University and stayed there in 1969 to take a Doctor of Philosophy, PhD in palaeontology supervised by Panchen focusing on the Nectridea, nectrideans, a group of Paleozoic tetrapods. Career Milner was first employed at the Natural History Museum, London, Natural History Museum in London in 1976. Her unusual career path led her to reach a management as well as scientific role, finally ...

Paleontologist
Paleontology (), also spelled palaeontology or palæontology, is the scientific study of life that existed prior to, and sometimes including, the start of the Holocene epoch (roughly 11,700 years before present). It includes the study of fossils to classify organisms and study their interactions with each other and their environments (their paleoecology). Paleontological observations have been documented as far back as the 5th century BC. The science became established in the 18th century as a result of Georges Cuvier's work on comparative anatomy, and developed rapidly in the 19th century. The term itself originates from Greek (, "old, ancient"), (, ( gen. ), "being, creature"), and (, "speech, thought, study"). Paleontology lies on the border between biology and geology, but differs from archaeology in that it excludes the study of anatomically modern humans. It now uses techniques drawn from a wide range of sciences, including biochemistry, mathematics, and engineering. ...

Specific Name (zoology)
In zoological nomenclature, the specific name (also specific epithet or species epithet) is the second part (the second name) within the scientific name of a species (a binomen). The first part of the name of a species is the name of the genus or the generic name. The rules and regulations governing the giving of a new species name are explained in the article species description. For example, the scientific name for humans is ''Homo sapiens'', which is the species name, consisting of two names: ''Homo'' is the " generic name" (the name of the genus) and ''sapiens'' is the "specific name". Historically, ''specific name'' referred to the combination of what are now called the generic and specific names. Carl Linnaeus, who formalized binomial nomenclature, made explicit distinctions between specific, generic, and trivial names. The generic name was that of the genus, the first in the binomial, the trivial name was the second name in the binomial, and the specific the proper term for ...

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 ...

Name Of A Biological Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should clearly demonstr ...

Type Species
In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specimen(s). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name that has that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have such types.

Million Years Ago
The abbreviation Myr, "million years", is a unit of a quantity of (i.e. ) years, or 31.556926 teraseconds. Usage Myr (million years) is in common use in fields such as Earth science and cosmology. Myr is also used with Mya (million years ago). Together they make a reference system, one to a quantity, the other to a particular place in a year numbering system that is ''time before the present''. Myr is deprecated in geology, but in astronomy ''Myr'' is standard. Where "myr" ''is'' seen in geology it is usually "Myr" (a unit of mega-years). In astronomy it is usually "Myr" (Million years). Debate In geology a debate remains open concerning the use of ''Myr'' (duration) plus ''Ma'' (million years ago) versus using only the term ''Ma''. In either case the term '' Ma'' is used in geology literature conforming to ISO 31-1 (now ISO 80000-3) and NIST 811 recommended practices. Traditional style geology literature is written The "ago" is implied, so that any such year number "X Ma" ...

Faunal Stage
In chronostratigraphy, a stage is a succession of rock strata laid down in a single age on the geologic timescale, which usually represents millions of years of deposition. A given stage of rock and the corresponding age of time will by convention have the same name, and the same boundaries. Rock series are divided into stages, just as geological epochs are divided into ages. Stages can be divided into smaller stratigraphic units called chronozones. (See chart at right for full terminology hierarchy.) Stages may also be divided into substages or indeed grouped as superstages. The term faunal stage is sometimes used, referring to the fact that the same fauna (animals) are found throughout the layer (by definition). Definition Stages are primarily defined by a consistent set of fossils (biostratigraphy) or a consistent magnetic polarity (see paleomagnetism) in the rock. Usually one or more index fossils that are common, found worldwide, easily recognized, and limited to a sing ...
