Kraglievichia
''Kraglievichia'' is an extinct genus of cingulate belonging to the family Pampatheriidae. It lived from the Late Miocene to the Early Pliocene, and its fossilized remains were discovered in South America. Description This animal looked like an enormous armadillo, with body dimensions comparable or larger than the modern giant armadillo ; its skull was 18 centimeters long. As for all its relatives, the pampatheres, the structure of the armor of ''Kraglievichia'' forbade it to curl up, as most modern armadillos does. The genus was characterized by the presence of four upper teeth and three lower teeth with an oval section, a characteristic differentiating it from the very similar but smaller ''Vassallia''. The osteoderms of its carapace had an elevated axial area, underlined by two lateral longitudinal depressions. Classification The genus ''Kraglievichia'' was established in 1927 by Castellanos, for a species of fossil cingulate first described in 1883 by Florentino Amegh ...

Vassallia
''Vassallia'' is an extinct genus of cingulate belonging to the family Pampatheriidae. It lived between the Middle Oligocene and the Early Pliocene in what is now South America. Description This animal must have been very similar in shape and size to today's giant armadillo (''Priodontes maximus''); it is likely that the largest species of ''Vassallia maxima'' could have exceeded one meter in length. Like all pampatheres, ''Vassallia'' was also equipped with an armor consisting of osteoderms articulated with each other to form two rigid structures, one anterior and one posterior, and a few bands of movable osteoderms that allowed partial movement of the back. ''Vassallia'' was very similar to another pampathere, '' Kraglievichia'' from which it differed mainly in some dental features (the teeth had a somewhat simpler structure) and bony plates, which had a main figure with a slightly elevated central area. A study carried out on the dentition and morphology of jaw and mandi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cingulata
Cingulata, part of the superorder Xenarthra, is an order of armored New World placental mammals. Dasypodids and chlamyphorids, the armadillos, are the only surviving families in the order. Two groups of cingulates much larger than extant armadillos (maximum body mass of 45 kg (100 lb) in the case of the giant armadillo) existed until recently: pampatheriids, which reached weights of up to 200 kg (440 lb) and chlamyphorid glyptodonts, which attained masses of 2,000 kg (4,400 lb) or more. The cingulate order originated in South America during the Paleocene epoch about 66 to 56 million years ago, and due to the continent's former isolation remained confined to it during most of the Cenozoic. However, the formation of a land bridge allowed members of all three families to migrate to southern North America during the Pliocene or early Pleistocene as part of the Great American Interchange. After surviving for tens of millions of years, all of the pampat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pampatheriidae
Pampatheriidae ("Pampas beasts") is an extinct family of large plantigrade armored armadillos related to extant armadillos in the order Cingulata. However, pampatheriids have existed as a separate lineage since at least the middle Eocene Mustersan age, . Pampatheres evolved in South America during its long period of Cenozoic isolation. Although widespread, they were less diverse and abundant than the armadillos. ''Holmesina'' spread to North America after the formation of the Isthmus of Panama as part of the Great American Interchange. They finally disappeared on both continents in the end-Pleistocene extinctions, about 12,000 years ago. Description Pampatheres are believed to have attained a weight of up to . Like three-banded armadillos, and unlike glyptodonts, their armored shell was given some flexibility by three movable lateral bands of scutes. The osteoderms (bony plates in the skin comprising the armor) of pampatheres were each covered by a single keratinized scute, ...

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. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

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 ...
