Hystrix (mammal)
''Hystrix'' is a genus of porcupines containing most of the Old World porcupines. Fossils belonging to the genus date back to the late Miocene of Africa. Hystrix (from Ancient Greek ὕστριξ (hústrix, “porcupine”)) was given name by the 18th century Swedish botanist, Carl Linnaeus.

Miocene
The Miocene ( ) is the first geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and means "less recent" because it has 18% fewer modern marine invertebrates than the Pliocene has. The Miocene is preceded by the Oligocene and is followed by the Pliocene. As Earth went from the Oligocene through the Miocene and into the Pliocene, the climate slowly cooled towards a series of ice ages. The Miocene boundaries are not marked by a single distinct global event but consist rather of regionally defined boundaries between the warmer Oligocene and the cooler Pliocene Epoch. During the Early Miocene, the Arabian Peninsula collided with Eurasia, severing the connection between the Mediterranean and Indian Ocean, and allowing a faunal interchange to occur between Eurasia and Africa, including the dispersal of proboscideans into Eurasia.

Old World Porcupine
The Old World porcupines, or Hystricidae, are large terrestrial rodents, distinguished by the spiny covering from which they take their name. They range over the south of Europe and the Levant, most of Africa, India, and Southeast Asia as far east as Flores. Although both the Old World and New World porcupine families belong to the infraorder Hystricognathi of the vast order Rodentia, they are quite different and are not particularly closely related. Characteristics Old World porcupines are stout, heavily built animals, with blunt, rounded heads, fleshy, mobile snouts, and coats of thick cylindrical or flattened spines, which form the whole covering of their bodies, and are not intermingled with ordinary hairs. The habits of most species are strictly terrestrial. They vary in size from the relatively small long–tailed porcupine with body lengths of , and a weight of , to the much larger crested porcupines, which are long, discounting the tail, and weigh from .

Johns Hopkins University Press
The Johns Hopkins University Press (also referred to as JHU Press or JHUP) is the publishing division of Johns Hopkins University. It was founded in 1878 and is the oldest continuously running university press in the United States. The press publishes books and journals, and operates other divisions including fulfillment and electronic databases. Its headquarters are in Charles Village, Baltimore. In 2017, after the retirement of Kathleen Keane who is credited with modernizing JHU Press for the digital age, the university appointed new director Barbara Pope. Overview Daniel Coit Gilman, the first president of the Johns Hopkins University, inaugurated the press in 1878. The press began as the university's Publication Agency, publishing the ''American Journal of Mathematics'' in its first year and the ''American Chemical Journal'' in its second. It published its first book, ''Sidney Lanier: A Memorial Tribute'', in 1881 to honor the poet who was one of the university's first writers ...

Hystrix Refossa
''Hystrix refossa'' is an extinct species of large porcupine that was widespread in Eurasia during the Pleistocene. Taxonomy ''Hystrix refossa'' was first described by palaeontologist Paul Gervais in 1852. Over the years, other large species of ''Hystrix'' have been described, including ''H. angressi'' from Israel and ''H. gigantea'' of Java. These forms are now considered synonymous with ''H. refossa''. Description ''Hystrix refossa'' was larger than living porcupines. It was approximately 20% larger than its closest relative, the living Indian porcupine (''H. indica''), reaching lengths of over . It also differs from the Indian porcupine in having a high and narrow occipital region, in the anteriorly convergent arrangement of maxillary cheek-teeth series, and in its mandible and the cheek-teeth pattern. Paleoecology The earliest remains of ''H. refossa'' are dated to the start of the Villafranchian and were found at the site of Milea, Grevena in northern Greece Greece,, ...

Hystrix Primigenia
''Hystrix primigenia'' is an extinct species of Old World porcupine that lived during the Late Miocene and Pliocene. Fossils of this species were recovered mainly from southern Europe, from Spain to Turkey and North Africa as well. The earliest fossils were found in Greece and the Balkan peninsula. ''Hystrix primigenia'' was much larger than living porcupines, perhaps as much as twice the size of the largest living species. It probably descended from a smaller, more primitive species known as ''Hystrix suevica Hystrix may refer to: * Ichthyosis hystrix, a class of rare skin disorder characterized by massive hyperkeratosis with an appearance like spiny scales Biology * ''Hystrix'' (diatom) , a diatom genus * ''Hystrix'' (plant) , a plant genus in th ...''.

Botanist
Botany, also called , plant biology or phytology, is the science of plant life and a branch of biology. A botanist, plant scientist or phytologist is a scientist who specialises in this field. The term "botany" comes from the Ancient Greek word (''botanē'') meaning "pasture", " herbs" "grass", or " fodder"; is in turn derived from (), "to feed" or "to graze". Traditionally, botany has also included the study of fungi and algae by mycologists and phycologists respectively, with the study of these three groups of organisms remaining within the sphere of interest of the International Botanical Congress. Nowadays, botanists (in the strict sense) study approximately 410,000 species of land plants of which some 391,000 species are vascular plants (including approximately 369,000 species of flowering plants), and approximately 20,000 are bryophytes. Botany originated in prehistory as herbalism with the efforts of early humans to identify – and later cultivate – edible, med ...

Ancient Greek
Ancient Greek includes the forms of the Greek language used in ancient Greece and the ancient world from around 1500 BC to 300 BC. It is often roughly divided into the following periods: Mycenaean Greek (), Dark Ages (), the Archaic period (), and the Classical period (). Ancient Greek was the language of Homer and of fifth-century Athenian historians, playwrights, and philosophers. It has contributed many words to English vocabulary and has been a standard subject of study in educational institutions of the Western world since the Renaissance. This article primarily contains information about the Epic and Classical periods of the language. From the Hellenistic period (), Ancient Greek was followed by Koine Greek, which is regarded as a separate historical stage, although its earliest form closely resembles Attic Greek and its latest form approaches Medieval Greek. There were several regional dialects of Ancient Greek, of which Attic Greek developed into Koine. Dia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
