Vallesian Crisis
The Vallesian age is a period of geologic time (11.6–9.0 Ma) within the Miocene used more specifically with European Land Mammal Ages. It precedes the Turolian age and follows the Astaracian age. The so-called Vallesian Crisis resulted in the extinction of several mammalian taxa characteristic of the Middle Miocene. The term "Vallesian" was introduced by Catalan palaeontologist Miquel Crusafont in 1950 to mark the arrival of the equid ''Hipparion'' in Europe. The remaining European palaeofaunas, however, had been around since the Middle Miocene, including the moschid ''Micromeryx'' (a musk deer), the cervid ''Euprox'', the suid '' Listriodon'', and the felids ''Sansanosmilus'' and ''Pseudaelurus'', and the Aragonian-Vallesian"Aragonian" is a Spanish term for a continental stage, roughly equivalent to the Middle Miocene or Astaracian (16–11 Ma). boundary does not represent a major shift in the European mammalian record. In contrast, the transition between Lower and Upper Va ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geologic Time
The geologic time scale, or geological time scale, (GTS) is a representation of time based on the rock record of Earth. It is a system of chronological dating that uses chronostratigraphy (the process of relating strata to time) and geochronology (scientific branch of geology that aims to determine the age of rocks). It is used primarily by Earth scientists (including geologists, paleontologists, geophysicists, geochemists, and paleoclimatologists) to describe the timing and relationships of events in geologic history. The time scale has been developed through the study of rock layers and the observation of their relationships and identifying features such as lithologies, paleomagnetic properties, and fossils. The definition of standardized international units of geologic time is the responsibility of the International Commission on Stratigraphy (ICS), a constituent body of the International Union of Geological Sciences (IUGS), whose primary objective is to precisely define ...

Bovid
The Bovidae comprise the biological family of cloven-hoofed, ruminant mammals that includes cattle, bison, buffalo, antelopes, and caprines. A member of this family is called a bovid. With 143 extant species and 300 known extinct species, the family Bovidae consists of 11 (or two) major subfamilies and thirteen major tribes. The family evolved 20 million years ago, in the early Miocene. The bovids show great variation in size and pelage colouration. Excepting some domesticated forms, all male bovids have two or more horns, and in many species, females possess horns, too. The size and shape of the horns vary greatly, but the basic structure is always one or more pairs of simple bony protrusions without branches, often having a spiral, twisted or fluted form, each covered in a permanent sheath of keratin. Most bovids bear 30 to 32 teeth. Most bovids are diurnal. Social activity and feeding usually peak during dawn and dusk. Bovids typically rest before dawn, during midday, an ...

Paramachairodus
''Paramachaerodus'' is an extinct genus of saber-tooth cat of the subfamily Machairodontinae, which was endemic to Europe and Asia during the late Miocene from 15 to 9 Ma. ''Paramacheirodus'' is one of the oldest known true saber-toothed cats. Many fossils were discovered in Cerro de los Batallones, a Late Miocene fossil site near Madrid, Spain. One leopard-sized species is known, ''Paramachaerodus orientalis'' from the Turolian. A second species, ''Paramachairodus maximiliani'', has been considered a synonym of ''Paramachaerodus orientalis'' by some authors, but was considered a valid species in the most recent systematic revision. That revision, based on an extensive morphological analysis, also determined that the species ''P. ogygia'' exhibited less derived sabertooth features than the other ''Paramachairodus'' species and should be assigned to a separate genus, ''Promegantereon''. A third species, ''Paramachairodus transasiaticus'', has recently been described based on analy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cricetidae
The Cricetidae are a family of rodents in the large and complex superfamily Muroidea. It includes true hamsters, voles, lemmings, muskrats, and New World rats and mice. At almost 608 species, it is the second-largest family of mammals, and has members throughout the Americas, Europe and Asia. Characteristics The cricetids are small mammals, ranging from just in length and in weight in the New World pygmy mouse up to and in the muskrat. The length of their tails varies greatly in relation to their bodies, and they may be either furred or sparsely haired. The fur of most species is brownish in colour, often with a white underbelly, but many other patterns exist, especially in the cricetine and arvicoline subfamilies. Like the Old World mice, cricetids are adapted to a wide range of habitats, from the high Arctic to tropical rainforests and hot deserts. Some are arboreal, with long balancing tails and other adaptations for climbing, while others are semiaquatic, with w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
