Dagbatitherium
''Dagbatitherium'' is an extinct genus of proboscideans. So far a single molar from the phosphate basins of Togo in West Africa has been found. The fossil dates to the Middle Eocene, around 47 million years ago. A striking feature of the tooth are the three pairs of cusps oriented transversely to the longitudinal axis of the tooth. This feature is found in more derived proboscideans, which are grouped in the Elephantiformes. For its age, ''Dagbatitherium'' is the earliest member of Elephantiformes to date. Furthermore, it is characterized by a low tooth crown and a humped occlusal pattern. The genus was described in 2021. Discovery and naming The only tooth of ''Dagbatitherium'' found so far is from West Africa and was recovered in the Hahotoé-Kpogamé phosphate complex. These are phosphate-bearing deposits formed in a coastal basin. They extend over a length of 30 to 35 km and a width of 2 to 3 km in a northeast-southwest direction between the towns of Dagbati and Aveta in To ...

Eritreum
''Eritreum melakeghebrekristosi'' is an extinct species of proboscidean mammal, which lived in Northeast Africa during the late Oligocene some 27 million years ago, and is considered to be the missing link between modern elephants and their ancestors. The fossil A fossil (from Classical Latin , ) is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved ...s of this species are the oldest known fossils featuring the horizontal tooth displacement seen in modern elephants. The species is estimated to have weighed and stood about at the shoulder, much smaller than modern species. The generic name ''Eritreum'' comes from Eritrea, the country in the Horn of Africa where the specimen was discovered. The specific name ''melakeghebrekristosi'' honors Melake Ghebrekristos, the farmer who found the specimen. References * ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Proboscidea
The Proboscidea (; , ) are a taxonomic order of afrotherian mammals containing one living family (Elephantidae) and several extinct families. First described by J. Illiger in 1811, it encompasses the elephants and their close relatives. From the mid-Miocene onwards, most proboscideans were very large. The largest land mammal of all time may have been a proboscidean; ''Palaeoloxodon namadicus'' was up to at the shoulder and may have weighed up to , almost double the weight of some sauropods like ''Diplodocus carnegii''. The largest extant proboscidean is the African bush elephant, with a record of size of at the shoulder and . In addition to their enormous size, later proboscideans are distinguished by tusks and long, muscular trunks, which were less developed or absent in early proboscideans. Three species of elephant are currently recognised: the African bush elephant, the African forest elephant, and the Asian elephant. Elephantidae is the only surviving family of the or ...

Palaeomastodon
''Palaeomastodon'' an extinct genus of Proboscidea. ''Palaeomastodon'' fossils have been found in Africa, where they lived some 36-35 million years ago. They are believed to be the ancestors of elephants or mastodons. ''Palaeomastodon'' lived in marshy semi aquatic swamps during the middle late Eocene to the early Oligocene. It may have used its upper pair of tusks for scraping bark off trees. ''Palaeomastodon'' was a very early form of elephant and thus had a very short trunk. ''Palaeomastodon'' had tusks Tusks are elongated, continuously growing front teeth that protrude well beyond the mouth of certain mammal species. They are most commonly canine teeth, as with pigs and walruses, or, in the case of elephants, elongated incisors. Tusks share ..., both upper and lower, and it had a trunk. It was about tall at the shoulder and weighed about . The lower tusks were flat rather than pointed cones, and were probably used to scoop plants from swampy water. ''Palaeomastod ...

Phiomia
''Phiomia'' is an extinct genus of basal proboscid that lived in what is now Northern Africa during the Late Eocene to Early Oligocene some 37–30 million years ago.Strauss, BPrehistoric Elephant Pictures and Profiles/ref> "''Phiomia serridens''" means "saw-toothed animal of Faiyum". Description ''Phiomia serridens'' (=''P. wintoni'', ''P. osborni'', ''P. minor'') is estimated to had shoulder height , while ''P. major'' got larger size. It vaguely resembled a modern elephant, although, based on the shape of its nasal bones, it had only a very short trunk. It had short tusks on the upper jaw and also short shovel-like tusks on the lower jaw that were most likely used for gathering food. These were similar to those of the Miocene ''Platybelodon'', ''Archaeobelodon'', and ''Amebelodon ''Amebelodon'' is a genus of extinct proboscidean belonging to Amebelodontidae (the so-called shovel-tuskers), a group of proboscideans related to the modern elephants and their close relative th ...

Mammutidae
Mammutidae is an extinct family of proboscideans that appeared during the Oligocene epoch and survived until the start of the Holocene. The family was first described in 1922, classifying fossil specimens of the type genus ''Mammut'' (mastodons), and has since been placed in various arrangements of the order. The name "mastodon" derives from Greek, "nipple" and "tooth", as with the genus, referring to a characteristic that distinguishes them from allied families. The genus ''Zygolophodon'' has also been assigned to this family. Mammutids ranged very widely, with fossils found in North America, Africa, and throughout Eurasia. Discoveries Since the 18th century several fossils have been found in different regions of Venezuela; the first one of these fossils was reviewed by Alexander von Humboldt. In August 2008, miners in Romania unearthed the skeleton of a 2.5-million-year-old mastodon, believed to be one of the best preserved in Europe.

Suborder
Order ( la, ordo) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between family and class. In biological classification, the order is a taxonomic rank used in the classification of organisms and recognized by the nomenclature codes. An immediately higher rank, superorder, is sometimes added directly above order, with suborder directly beneath order. An order can also be defined as a group of related families. What does and does not belong to each order is determined by a taxonomist, as is whether a particular order should be recognized at all. Often there is no exact agreement, with different taxonomists each taking a different position. There are no hard rules that a taxonomist needs to follow in describing or recognizing an order. Some taxa are accepted almost universally, while others are recognized only rarely. The name of an order is usually written with a capital letter. For some groups of organisms, their orders may follow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elephantidae
Elephantidae is a family (biology), family of large, herbivorous proboscidean mammals collectively called elephants and mammoths. These are terrestrial animal, terrestrial large mammals with a snout modified into a Elephant#Trunk, trunk and teeth modified into tusks. Most Genus, genera and species in the family are extinction, extinct. Only two genera, ''Loxodonta'' (African elephants) and ''Elephas'' (Asiatic elephants), are Extant taxon, living. The family was first described by John Edward Gray in 1821, and later assigned to taxonomic ranks within the order Proboscidea. Elephantidae has been revised by various authors to include or exclude other extinct proboscidean genera. Classification Scientific classification of Elephantidae taxa embraces an extensive record of fossil specimens, over millions of years, some of which existed until the end of the last ice age. Some species were extirpated more recently. The discovery of new specimens and proposed cladistics have result ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
