Aglaocrinus Sutherlandi
''Aglaocrinus'' is an extinct species of crinoids in the ''Cladia'' order. It has been proposed that it was a blind, stationary (attached) suspension feeder the hard parts of which were composed of magnesium calcite. It has been discovered in 3 locations in North America. Species There are currently 12 species in this genus, consisting of: *'' Aglaocrinus cranei'' (Strimple, 1971); also known as ''Aaglaocrinus cranei'' *'' Aglaocrinus expansus'' *''Aglaocrinus keytei'' (Strimple & Moore 1973); also known as ''Aaglaocrinus keytai'' *''Aglaocrinus konecnyorum'' (Webster 1981) *''Aglaocrinus magnus'' (Strimple 1949) *'' Aglaocrinus nacoensis'' (Webster 1981) *'' Aglaocrinus oklahomensis'' (Moore & Plummer 1938); also known as ''Ethelocrinus oklahomensis'' (Moore & Plummer, 1938) *'' Aglaocrinus rectilatus'' (Lane & Webster, 1966) *'' Aglaocrinus supplantus'' (Pabian & Strimple 1974); also known as ''Aaglaocrinus supplantus'' *'' Aglaocrinus sutherlandi'' (Strimple 1980) *''Aglaoc ...

Prehistoric Crinoid 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] |
Paleozoic Echinoderms Of North America
The Paleozoic (or Palaeozoic) Era is the earliest of three geologic eras of the Phanerozoic Eon. The name ''Paleozoic'' ( ;) was coined by the British geologist Adam Sedgwick in 1838 by combining the Greek words ''palaiós'' (, "old") and ''zōḗ'' (), "life", meaning "ancient life" ). It is the longest of the Phanerozoic eras, lasting from , and is subdivided into six geologic periods (from oldest to youngest): # Cambrian # Ordovician # Silurian # Devonian # Carboniferous # Permian The Paleozoic comes after the Neoproterozoic Era of the Proterozoic Eon and is followed by the Mesozoic Era. The Paleozoic was a time of dramatic geological, climatic, and evolutionary change. The Cambrian witnessed the most rapid and widespread diversification of life in Earth's history, known as the Cambrian explosion, in which most modern phyla first appeared. Arthropods, molluscs, fish, amphibians, reptiles, and synapsids all evolved during the Paleozoic. Life began in the ocean but e ...
