Phlyctaenopyga
''Phlyctaenopyga'' is an extinct genus of Glyptodont. It lived from the Late Miocene to the Early Pliocene, and its fossilized remains were discovered in South America. Description Like all glyptodonts, this animal had a robust carapace, formed by osteoderms fused together, covering a large part of its body. ''Phlyctaenopyga'' was a medium-sized glyptodont, not exceeding two meters in length. Its carapace was made of osteoderms whose central figure was surrounded by two or three rows of peripheral figures ; the second row was complete only in a few osteoderms in ''Phlyctaenopyga ameghini'', while the third row was always incomplete. The central figure of the osteoderms was convex and protruding, almost hemispherical. The skull was very short and broad, especially in the snout area. The osteoderms covering the head were practically devoid of ornamentation. Classification The genus ''Phlyctaenopyga'' was first described in 1944 by Cabrera, for a species of Late Miocene glyptodo ...

Plohophorus
''Plohophorus'' is an extinct genus of Glyptodont. it lived from the Late Miocene to the Late Pliocene, and its fossilized remains were discovered in South America. Description Like all glyptodonts, this animal had a large carapace formed by numerous osteoderms fused together, covering most of its body. ''Plohophorus'' shared similarities with another Miocene glyptodont, ''Phlyctaenopyga'', especially in its rather broad and low skull. The ornamentation of the caudal tube, protecting the tail, was more simplified ; the peripheral figures were partially regressed and marked in the distal part ; the central oval-shaped figures were contiguous to each other and only left space for small triangular areas between each other. Classification The genus ''Plohophorus'' was first described in 1887 by Florentino Ameghino, based on fossil remains found in Upper Miocene terrains of Argentina. The type species is ''Plohophorus figuratus'' ; several other species from the Late Miocene and t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Miocene
The Miocene ( ) is the first geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and means "less recent" because it has 18% fewer modern marine invertebrates than the Pliocene has. The Miocene is preceded by the Oligocene and is followed by the Pliocene. As Earth went from the Oligocene through the Miocene and into the Pliocene, the climate slowly cooled towards a series of ice ages. The Miocene boundaries are not marked by a single distinct global event but consist rather of regionally defined boundaries between the warmer Oligocene and the cooler Pliocene Epoch. During the Early Miocene, the Arabian Peninsula collided with Eurasia, severing the connection between the Mediterranean and Indian Ocean, and allowing a faunal interchange to occur between Eurasia and Africa, including the dispersal of proboscideans into Eurasia.

Prehistoric Placental Genera
Prehistory, also known as pre-literary history, is the period of human history between the use of the first stone tools by hominins 3.3 million years ago and the beginning of recorded history with the invention of writing systems. The use of symbols, marks, and images appears very early among humans, but the earliest known writing systems appeared 5000 years ago. It took thousands of years for writing systems to be widely adopted, with writing spreading to almost all cultures by the 19th century. The end of prehistory therefore came at very different times in different places, and the term is less often used in discussing societies where prehistory ended relatively recently. In the early Bronze Age, Sumer in Mesopotamia, the Indus Valley Civilisation, and ancient Egypt were the first civilizations to develop their own scripts and to keep historical records, with their neighbors following. Most other civilizations reached the end of prehistory during the following Iron Age. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
