Prehistory
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 Ir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of European Dinosaurs
Dinosaurs evolved partway through the Triassic period of the Mesozoic era, around 230 Ma (million years ago). At that time, the earth had one supercontinental landmass, called Pangaea, of which Europe was a part. So it remained throughout the Triassic. By the start of the Jurassic period, some 30 million years later, the supercontinent began to split into Laurasia and Gondwana. The largest inlet from Panthalassa, the superocean that surrounded Pangaea, was called the Tethys Ocean, and as this inlet cut deeper into the supercontinent, much of Europe was flooded. By the Cretaceous, from 145 to 66 million years ago, the continents were beginning to approach their present shapes, but not their present positions, and Europe remained tropical. At times, it was a chain of island-microcontinents including Baltica and Iberia. Europe is relatively rich in fossils from the Jurassic-Cretaceous boundary, and much of what is known about European dinosaurs dates from this time. During t ...

List Of Prehistoric Starfish Genera
This list of prehistoric starfish is an attempt to create a comprehensive listing of all Genus, genera from the fossil record that have ever been considered to be in the class Asteroidea, excluding purely vernacular terms.

Naming conventions and terminology Naming conventions and terminology follow the International Code of Zoological Nomenclature. Technical terms used include: * Synonym (zoology), Junior synonym: A name which describes the same taxon as a previously published name. If two or more genera are formally designated and the type (zoology), type specimens are later assigned to the same genus, the first to be published (in chronological order) is the ...

List Of Dinosaurs Of The Morrison Formation
The Morrison Formation is a distinctive sequence of Upper Jurassic sedimentary rock that is found in the western United States, which has been the most fertile source of dinosaur fossils in North America. It is composed of mudstone, sandstone, siltstone and limestone and is light grey, greenish gray, or red. Most of the fossils occur in the green siltstone beds and lower sandstones, relics of the rivers and floodplains of the Jurassic period. Fauna comparisons The fauna of Morrison Formation is similar to one in the coeval rocks of Tendaguru Beds (in Tanzania) and Lourinhã Formation in Portugal, mostly with the second. Some genera are shared in Morrison and Lourinhã, such as ''Torvosaurus'', ''Ceratosaurus'', ''Stegosaurus'', ''Dryosaurus'', and ''Allosaurus''.Mateus, O, Walen A, Antunes MT. 2006.

List Of Archosaurs Of The Chinle Formation
The Chinle Formation is an Upper Triassic continental geologic formation in the western United States which has yielded fossils of many archosaurs: a group of vertebrates that includes crocodiles, pterosaurs, dinosaurs (including birds), and other extinct relatives. This is a list of all archosaurs from the formation, including suchians (crocodilian relatives) and avemetatarsalians (dinosaurs, pterosaurs, and their relatives), as well as the abundant crocodilian-like phytosaurs, which may either be true archosaurs or very close relatives of Archosauria. Phytosaurs Suchians Aetosaurs Crocodylomorphs Other paracrocodylomorphs Other suchians Avemetatarsalians Basal avemetatarsalians Dinosaurs Sauropodomorphs Prosauropod tracks are present in the Redonda, Sloan Canyon, and Sheep Pen Sandstone formations. Possibly the Rock Point Formation as well. Geographically, the tracks are present in New Mexico.Weishampel, David B; et al. (2004). "Dinosaur distribution (Late ...
