Neobrachytherium
''Neobrachytherium'' is an extinct genus of proterotheriid mammal from the Late Miocene of Argentina and Uruguay. It is represented by multiple species, including the type ''N. intermedium'', originally named in 1891 by Moreno and Mercerat as a species of '' Licaphrium'', ''N. morenoi'', originally named in 1914 by Rovereto as a species of ''Brachytherium'', and ''N. ameghinoi'' and ''N. ullumense'', named in 2001 by Soria, who reclassified all the species in the new genus ''Neobrachytherium''. The various species are known from cranial and dental material from the Corral Quemado, Loma de las Tapias and Ituzaingó Formations. ''Neobrachytherium'' may be closely related to ''Thoatherium ''Thoatherium'' (meaning "active swift-beast") is an extinct genus of litoptern mammals from the Early Miocene of Argentina. Fossils of the genus have been found in the Santa Cruz Formation in Argentina. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Huayquerian
The Huayquerian ( es, Huayqueriense) age is a period of geologic time (9.0–6.8 Ma) within the Late Miocene epoch of the Neogene, used more specifically within the SALMA classification. It follows the Mayoan and precedes the Montehermosan age. Etymology The age is named after the Huayquerías Formation in the western Cuyo Basin of northwestern Argentina that was later dated to the Montehermosan. The most complete Huayquerian fauna is found in the Cerro Azul Formation The Cerro Azul Formation ( es, Formación Cerro Azul), in the Buenos Aires Province also described as Epecuén Formation, is a geological formation of Late Miocene (Tortonian, or Huayquerian in the SALMA classification) age in the Colorado Basin ..., in Buenos Aires Province also referred to as Epecuén Formation.

Proterotheriidae
Proterotheriidae is an extinction, extinct family of fossil ungulates from the Cenozoic era that displays toe reduction. Despite resembling primitive, small horses, they were only distantly related to them, and instead belonged to the native South American ungulate order Litopterna. Description Two subfamilies and 18 genera of Proterotheriidae are known. All forms were small or medium-sized. Typical is a reduction of the number of toes and brachydont or mesodont teeth. The family is recorded since the late Palaeocene. Various fossils are known from many parts of the South American continent. The diversity decreased in the Miocene to Pliocene and it has been assumed for a long time that they entirely disappeared in the late Pliocene. However, fossils found in Argentina, Brazil and Uruguay show that one member of the group, ''Neolicaphrium recens'' survived into the Late Lujanian, Pleistocene. Better known genera of the family include ''Diadiaphorus'' and ''Thoatherium'' from th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Thoatheriopsis
''Thoatheriopsis'' is an extinct genus of proterotheriid from the Miocene of Mendoza Province, Argentina. The taxon is known only from the specimen MLP 81-XI-28-1, which includes an upper tooth row, and was named as the new binomial ''Thoatheriopsis mendocensis'' by Miguel Soria posthumously in 2001. The only provenance information known about the specimen is that it comes from the Anfiteatro de Cacheuta, and it is probably from the Mariño Formation, of which it could be from either the Areniscas Entrecruzadas or the Estratos de Mariño Member, which are both present at the known location of discovery. This means that the age for ''Thoatheriopsis'' cannot be determined beyond either being from the Santacrucian or Laventan South American Land Mammal Ages in the Early or Middle Miocene. ''Thoatheriopsis'' was found to be a close relative of ''Diadiaphorus'' and ''Neobrachytherium ''Neobrachytherium'' is an extinct genus of proterotheriid mammal from the Late Miocene of Argenti ...

Licaphrium
''Anisolophus'' is an extinct genus of proterotheriid from the Early to Middle Miocene of Argentina. The genus was named by Burmeister in 1885 to accommodate the species ''Anchitherium australe'', which they had named earlier in 1879. Soria then referred the species ''Licaphrium floweri'' and ''Anisolophus minisculus'' to the genus, making ''Licaphrium'', named in 1887 by Florentino Ameghino, a junior synonym of the genus. Both ''A. australis'' and ''A. floweri'' are known from the Santacrucian age Santa Cruz Formation, while ''A. minisculus'' is known from the Collón Curá Formation. ''Anisolophus'' is considered the senior synonym of the genus ''Licaphrium'', which was named in 1887 by Ameghino for the species ''L. floweri'', now ''A. floweri''. Many other species of ''Licaphrium'' were named, many of which are considered synonyms of ''A. floweri'', '' Tetramerorhinus'', ''Neobrachytherium'', or '' Lophogonodon'', as well as the dubious Doubt is a mental state in which the ...

Brachytherium
''Brachytherium'' is an extinct genus of proterotheriid mammal from the Late Miocene to Late Pliocene of Argentina. It is represented by the type and only species ''B. cuspidatum'', a taxon named in 1883 by Ameghino for a partial mandible with teeth. Though it was considered a dubious taxon at times, ''Brachytherium'' was revised as valid by Schmidt in 2015, who also synonymized the species ''Proterotherium gradatum'' and ''Lophogonodon paranensis'', expanding the material known, all of which is from the Ituzaingó Formation The Ituzaingó Formation ( es, Formación Ituzaingó), in older literature also described as Entre Ríos or Entrerriana Formation, is an extensive geological formation of Late Miocene (Tortonian, or Huayquerian in the SALMA classification) age in ....

Fossils Of Uruguay
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 in amber, hair, petrified wood and DNA remnants. The totality of fossils is known as the ''fossil record''. Paleontology is the study of fossils: their age, method of formation, and evolutionary significance. Specimens are usually considered to be fossils if they are over 10,000 years old. The oldest fossils are around 3.48 billion years old to 4.1 billion years old. Early edition, published online before print. The observation in the 19th century that certain fossils were associated with certain rock strata led to the recognition of a geological timescale and the relative ages of different fossils. The development of radiometric dating techniques in the early 20th century allowed scientists to quantitatively measure the absolute ...

Neogene Uruguay
The Neogene ( ), informally Upper Tertiary or Late Tertiary, is a Geologic time scale#Terminology, geologic period and system that spans 20.45 million years from the end of the Paleogene Period million years ago (Year#Abbreviations yr and ya, Mya) to the beginning of the present Quaternary Period Mya. The Neogene is sub-divided into two Epoch (geology), epochs, the earlier Miocene and the later Pliocene. Some geologists assert that the Neogene cannot be clearly delineated from the modern geological period, the Quaternary. The term "Neogene" was coined in 1853 by the Austrian palaeontologist Moritz Hoernes, Moritz Hörnes (1815–1868). During this period, mammals and birds continued to evolve into modern forms, while other groups of life remained relatively unchanged. The first humans (''Homo habilis'') appeared in Africa near the end of the period. Some continental movements took place, the most significant event being the connection of North America, North and South America ...
