Odontopleuridae - Wikipedia
Odontopleuridae is a family of odontopleurid trilobites found in marine strata throughout the world. Odontopleurids of Odontopleuridae first appear in Late Cambrian -aged marine strata, and the last genera perish by the end of the Frasnian stage during the Late Devonian.
Odontopleurida - Wikipedia
Odontopleurida is an order of very spinose trilobites closely related to the trilobites of the order Lichida. [1] Some experts group the Odontopleurid families, Odontopleuridae and Damesellidae, within Lichida. Odontopleurids tend to have convex, bar-shaped cephalons, and lobed, knob-shaped glabella that extend to, or almost to the anterior margin.
Odontopleura - Wikipedia
Odontopleura is a genus of spinose odontopleurid trilobite in the family Odontopleuridae, and is the type genus of that family and of Odontopleurida. The various species are found in Upper Ordovician to Middle Devonian marine strata throughout the world.
Pattern and process in the evolution of the Odontopleuridae …
The systematics of parts of the Odontopleuridae are revised using character analyses tracing homologous structures, and a computerised cladistic analysis. The choice of outgroup is shown to affect the result of the analysis.
Odontopleuridae - Atlas of Ordovician Life
Odontopleuridae is an extinct family of fast-moving low-level epifaunal carnivores. Description of the Family. A distinct group of very spinose trilobites. Cephalon convex, the glabella tapers forward or sub-parallel and maximum width generally at the occipital ring. Thorax usually has 8-10 segments, at the end of which are 2-3 pairs of spines.

2015年7月14日 · Odontopleura ( Odontopleura) arctica, a new species of odontopleurine trilobite, is described from the Canadian Arctic. A method of cladistic analysis is detailed. Parsimony analysis should be performed treating all characters as unordered.
Within recent years trilobites of odontopleurid type have been described from the Middle and Upper Cambrian of Kazakh and Siberia. First to be made known was Acidaspides precurrens LERMONTOVA, 1951 (pp. 27-29, PI. 6, figs. 4-9), and a seeond species is A. lermontovae TCHERNYSHEVA, 1953 (pp. 81-83, PI. 6, figs. 16, 17).
