Fossils have been recovered from Yunnan Province, China to the Stinchar River, United Kingdom to Ringerike, Norway. History A cranidium of ''Atractopyge'' was already illustrated by the Welsh scientist Edward Lhuyd in 1698. The species ''xipheres'' is commonly referenced as ''A. Xipheres'' (Öpik, 1937), particularly on commercial websites. However, Öpik first described the species in 1925 as ''Cybele xiphere'' (Öpik, 1925, pp. 11, fig. 1: 10, 11) and later (1937, pp. 121, fig. VII 3; XXI 3, 4) desc ...

Balizoma
''Balizoma'' is a genus of trilobites from the family Encrinuridae established by David J. Holloway in 1980. It has only been found in rocks of Silurian age. Its type species, ''B. variolaris'' (Brongniart, 1822), is currently the only named species of the genus, and is found in England. The neotype of ''B. variolaris'' was collected from the Much Wenlock Limestone Formation at Dudley, West Midlands. That specimen was first illustrated in Sir Roderick Impey Murchison's classic book, '' The Silurian System''. ''B. variolaris'' was the original "strawberry-headed" trilobite of Dudley, so-named because of its nodular glabellar tubercles, and well known to early trilobite collectors. Additional species were originally assigned to ''Balizoma'', but were subsequently placed in other encrinurine genera.

Curriella
''Curriella'' is a genus of trilobites in the order Phacopida, that existed during the lower Silurian in what is now Scotland. It was described by Lamont in 1978, and the type species is ''Curriella newlandensis''; the species epithet was derived from the type location, the Newlands Formation. It also contains the species ''C. clancyi''. P.A. Jell and J.M. Adrain. References External links ''Curriella'' at the |

Phacopida
Phacopida ("lens-face") is an order of trilobites that lived from the Late Cambrian to the Late Devonian. It is made up of a morphologically diverse assemblage of taxa in three related suborders. Characteristics Phacopida had 8 to 19 thoracic segments and are distinguishable by the expanded glabella, short or absent preglabellar area, and schizochroal (Phacopina) or holochroal (Cheirurina and Calymenina) eyes. Schizochroal eyes are compound eyes with up to around 700 separate lenses. Each lens has an individual cornea which extended into a rather large sclera. The development of schizochroal eyes in phacopid trilobites is an example of post-displacement paedomorphosis. The eyes of immature holochroal Cambrian trilobites were basically miniature schizochroal eyes. In Phacopida, these were retained, via delayed growth of these immature structures (post-displacement), into the adult form. '' Eldredgeops rana'' (Phacopidae) and '' Dalmanites limulurus'' (Dalmanitidae) are tw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
