Atdabanella
''Atdabanella'' is an extinct genus from a well-known class of fossil marine arthropods, the trilobites.

This faunal stage was part of the Cambrian Period The Cambrian Period ( ; sometimes symbolized C with bar, Ꞓ) was the first geological period of the Paleozoic Era, and of the Phanerozoic Eon.

Ogygopsis
''Ogygopsis'' is a genus of trilobite from the Cambrian of Antarctica and North America, specifically the Burgess Shale. It is the most common fossil in the Mt. Stephen fossil beds there, but rare in other Cambrian faunas. Its major characteristics are a prominent glabella with eye ridges, lack of pleural spines, a large spineless pygidium about as long as the thorax or cephalon, and its length: up to 12 cm.Coppold, Murray and Wayne Powell (2006).

Corynexochina
Corynexochina is a poorly understood subdivision of the trilobite order Corynexochida Corynexochida is an order of trilobite that lived from the Lower Cambrian to the Late Devonian.

Olenoides
''Olenoides'' was a trilobite from the Cambrian period. Its fossils are found well-preserved in the Burgess Shale in Canada. It grew up to 10 cm (3.9 in) long. Etymology ''Olenoides'' – from ''Olenus'', in Greek mythology a man who, along with his wife Lethaea, was turned to stone. ''Olenus'' was used for a trilobite genus name in 1827; the suffix -''oides''(“resembling”) was added later. Discussion ''Olenoides'' followed the basic structure of all trilobites — a cephalon (head shield), a thorax with seven jointed parts, and finally a semicircular pygidium. Its antennae were long, and curved back along its sides. Its thin legs show that it was no swimmer, instead crawling along the sea floor in search of prey. This is also evidenced by fossil tracks that have been found. Conspicuous W-shaped wounds, often partially healed, on ''Olenoides'' specimens may be due to predation by ''Anomalocaris''. Its major characteristics are a large parallel-sided glabella, deep int ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trilobite
Trilobites (; meaning "three lobes") are extinct marine arthropods that form the class Trilobita. Trilobites form one of the earliest-known groups of arthropods. The first appearance of trilobites in the fossil record defines the base of the Atdabanian stage of the Early Cambrian period () and they flourished throughout the lower Paleozoic before slipping into a long decline, when, during the Devonian, all trilobite orders except the Proetida died out. The last extant trilobites finally disappeared in the mass extinction at the end of the Permian about 252 million years ago. Trilobites were among the most successful of all early animals, existing in oceans for almost 270 million years, with over 22,000 species having been described. By the time trilobites first appeared in the fossil record, they were already highly diversified and geographically dispersed. Because trilobites had wide diversity and an easily fossilized exoskeleton, they left an extensive fossil record. The stu ...
