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.

Phoberomys Pattersoni
''Phoberomys pattersoni'' is an extinct rodent that lived in the ancient Orinoco River delta around 8 million years ago. It was the second-largest of the roughly seven species of its genus. Like many other rodents, ''Phoberomys'' was a herbivore with high-crowned premolars and molars. Description An almost complete skeleton was discovered in the Urumaco Formation at Urumaco, Venezuela, in 2000.''Phoberomys pattersoni'' at .org The new species was later classified with the name ''Phoberomys pattersoni'' in honor of palaeontologist Brian Patterson. Originally, ''Phoberomys pattersoni'' was estimated as being approximately 741 kg based on dimensions of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phoberomys Insolita
''Phoberomys insolita'' is an extinct species of rodent that was known as the largest rodent on earth, before the discovery of ''Josephoartigasia monesi''. Fossil specimens from the Late Miocene period have been discovered in the Ituzaingó Formation of Argentina.''Phoberomys insolita'' at Fossilworks.org It has been synonymized with '' Phoberomys burmeisteri''.

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 the Paraná Basin of the Corrientes, Santa Fe and Entre Ríos Provinces in Mesopotamia, northeastern Argentina.Ituzaingó Formation at .org The formation comprises s, cross-bedded |

Urumaco Formation
The Urumaco Formation is a formation in Venezuela that includes deposits from the Late Miocene. It is the site of several "giant forms": the turtles, crocodiles, sloths and rodents of Urumaco are among the largest of their groups. Location The Urumaco formation is located in the Urumaco region in the Caribbean coastal Falcón state. The deposits date from 10 to 5.3 million years ago and the Urumaco formation was deposited in an area with large rivers, swamps, estuaries, lagoons and shallow coastal seas. These conditions in the Late Miocene contrast strongly with the current dry environment in the area today. Fauna Cartilaginous fish There are 21 known species of cartilaginous fishes from the Urumaco Formation, belonging to the orders Lamniformes, Carcharhiniformes, Myliobatiformes and Rajiformes. ''Carcharhinus caquetius'' is an endemic species of predator shark from Urumaco. A large number of well-preserved fossils of the sawfish ''Pristis rostra'' have been found in th ...

Urumaco
Urumaco is a town in Falcón State in Venezuela. It is of interest to paleontologists due to its rich fossil history. The arid climate of the region means that the fossils are not hidden by vegetation. The fossils were first made known to science by geologists who came across them while looking for oil, which is abundant in some parts of Venezuela. The paleontological wealth of Urumaco makes it the most fossil-rich zone of northern South America. '' Stupendemys geographicus'', the largest turtle ever to have existed, was found here in the 1970s by researchers from Harvard University. More recently, publicity has been attracted by discoveries of the giant rodent ''Phoberomys pattersoni'' from the Miocene epoch. Since 2000 there has been a museum in the town, the ''Museo Paleontológico de Urumaco''. There is an Archaeology and Paleontology Park in La Cruz de Taratara, a small town in Sucre near Coro.

Neogene Argentina
The Neogene ( ), informally Upper Tertiary or Late Tertiary, is a geologic period and system that spans 20.45 million years from the end of the Paleogene Period million years ago ( Mya) to the beginning of the present Quaternary Period Mya. The Neogene is sub-divided into two 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 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 and South America at the Isthmus of Panama, late in the Pliocene. This cut off the warm ocean currents from the Pacific to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fossil Taxa Described In 1926
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 abso ...
