Hemimachairodus
''Hemimachairodus'' is an extinct genus of saber-tooth cat of the tribe Machairodontini and subfamily Machairodontinae. The type species, ''Hemimachairodus zwierzyckii'' was previously assigned to the genus ''Homotherium''. Fossil segments of Hemimachairodus were unearthed in Pleistocene dig sites in Java in Indonesia alongside other predators such as ''Panthera tigris'', ''Homotherium ultimum'', and ''Megacyon merriami ''Megacyon merriami'', or Merriam's dog, was a prehistoric canid that lived in the early/middle Pleistocene (about 800-300 thousand years ago). Its fossilized remains have been found on the island of Java. Its scientific name means "Merriam's lar ...'', and it most likely competed with these species for prey.

Machairodontini
Machairodontini is an extinct tribe of large saber-toothed cats of the subfamily Machairodontinae, that lived in Europe, Asia, Africa, and North America, during the Middle and Late Miocene. Description Machairodont means "knife-tooth" which perfectly describes the species that make up Machairodontini. These predators are related to extant cats, the Felinae, and share a common ancestor within the Felidae clade. Machairodontines were medium to large sized saber-toothed cats that would have reached a size rivaling today's lions, which can reach weights of over . This clade is also occasionally classified as being part of the Homotherini, and includes genera such as ''Machairodus'', Hemimachairodus and '' Miomachairodus''. They were first characterized by their scimitar canines in the upper jaw. This means that the canines are shorter and coarsely serrated, with vertical flattening.Antón, Mauricio. 2013.

Saber-tooth Cat
Machairodontinae is an extinct subfamily of carnivoran mammals of the family Felidae (true cats). They were found in Asia, Africa, North America, South America, and Europe from the Miocene to the Pleistocene, living from about 16 million until about 11,000 years ago. The Machairodontinae contain many of the extinct predators commonly known as "saber-toothed cats", including the famed genus ''Smilodon'', as well as other cats with only minor increases in the size and length of their maxillary canines. The name means "dagger-tooth", from Greek μάχαιρα (''machaira''), sword. Sometimes, other carnivorous mammals with elongated teeth are also called saber-toothed cats, although they do not belong to the felids. Besides the machairodonts, other saber-toothed predators also arose in the nimravids, barbourofelids, machaeroidines, hyaenodonts and even in two groups of metatherians (the thylacosmilid sparassodonts and the deltatheroideans).

Gustav Heinrich Ralph Von Koenigswald
Gustav Heinrich Ralph (often cited as G. H. R.) von Koenigswald (13 November 1902 – 10 July 1982) was a German-Dutch paleontologist and geologist who conducted research on hominins, including ''Homo erectus''. His discoveries and studies of hominid fossils in Java and his studies of other important fossils of south-eastern Asia firmly established his reputation as one of the leading figures of 20th-century paleo-anthropology. Biography Von Koenigswald was born in Berlin in a period of intense interest and rapid growth in the study of evolution. He began his fossil vertebrate collection when he was fifteen with the acquisition of a rhinoceros molar during an excursion to Mauer, Germany. He subsequently studied geology and paleontology at Berlin, Tübingen, Cologne and Munich. Java Von Koenigswald's teacher Ferdinand Broili had good contacts with the Dutch geologists Karl Martin and Reinout Willem van Bemmelen. Through these contacts Von Koenigswald c ...

Extinction
Extinction is the termination of a kind of organism or of a group of kinds (taxon), usually a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and recover may have been lost before this point. Because a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the fossil record) after a period of apparent absence. More than 99% of all species that ever lived on Earth, amounting to over five billion species, are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryote globally, and possibly many times more if microorganisms, like bacteria, are included. Notable extinct animal species include non-avian dinosaurs, saber-toothed cats, dodos, m ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), 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 taxonomy (biology), 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 ...

Homotherium
''Homotherium'', also known as the scimitar-toothed cat or scimitar cat, is an extinct genus of machairodontine saber-toothed predator, often termed scimitar-toothed cats, that inhabited North America, South America, Eurasia, and Africa during the Pliocene and Pleistocene epochs (4 mya – 12,000 years ago), existing for approximately . It became extinct in Africa some 1.5 million years ago. The most recent Eurasian remains, recovered from what is now the North Sea, have been dated to around 28,000 years BP. In South America it is only known from a few remains in the northern region (Venezuela), from the mid-Pleistocene. Taxonomy and distribution The name ''Homotherium'' (Greek: (, 'same') and (, 'beast')) was proposed by Emilio Fabrini (1890), without further explanation, for a new subgenus of ''Machairodus'', whose main distinguishing feature was the presence of a large diastema between the two inferior premolars. The lineage of ''Homotherium'' is estimated (based on ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Panthera Tigris
The tiger (''Panthera tigris'') is the largest living cat species and a member of the genus '' Panthera''. It is most recognisable for its dark vertical stripes on orange fur with a white underside. An apex predator, it primarily preys on ungulates, such as deer and wild boar. It is territorial and generally a solitary but social predator, requiring large contiguous areas of habitat to support its requirements for prey and rearing of its offspring. Tiger cubs stay with their mother for about two years and then become independent, leaving their mother's home range to establish their own. The tiger was first scientifically described in 1758. It once ranged widely from the Eastern Anatolia Region in the west to the Amur River basin in the east, and in the south from the foothills of the Himalayas to Bali in the Sunda Islands. Since the early 20th century, tiger populations have lost at least 93% of their historic range and have been extirpated from Western and Central Asia, ...

Megacyon Merriami
''Megacyon merriami'', or Merriam's dog, was a prehistoric canid that lived in the early/middle Pleistocene (about 800-300 thousand years ago). Its fossilized remains have been found on the island of Java. Its scientific name means "Merriam's large dog". Description The fossil remains of this canid are incomplete, hence they do not provide an accurate reconstruction. The species appears to have been diverged from ''Xenocyon'', along with the African wild dog, Sardinian dhole and ''Mececyon trinilensis'', another extinct Javanese canid. The Merriam's dog had a set of strong, robust teeth. Its size probably exceeded that of the extant African wild dog The African wild dog (''Lycaon pictus''), also called the painted dog or Cape hunting dog, is a wild canine which is a native species to sub-Saharan Africa.

Pleistocene Carnivorans
The Pleistocene ( , often referred to as the ''Ice age'') is the geological epoch that lasted from about 2,580,000 to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek grc, label=none, πλεῖστος, pleīstos, most and grc, label=none, καινός, kainós (latinized as ), 'new'. At the end of the preceding Pliocene, the previously isolated North and South American continents were joined by the Isthmus of Panama, causing a faunal interchange between the two reg ...
