Styginidae
Styginidae is a family of trilobite in the order Corynexochida. Fossils of the various genera are found in marine strata throughout the world, aged from Ordovician up until the family's extinction during the Silurian.

Bumastus
''Bumastus'' is an extinct genus of Corynexochida, corynexochid trilobites which existed from the Early Ordovician Period (geology), period to the Late Silurian period. They were relatively large trilobites, reaching a length of . They were distinctive for their highly globular, smooth-surfaced exoskeleton. They possessed well-developed, large compound eyes and were believed to have dwelled in shallow-water sediments in life. ''Bumastus'' fossils have been found in North America, North and South America, Europe, Asia, and Australia. They are classified under the Family (biology), family Styginidae in the Order (biology), order Corynexochida. Description ''Bumastus'' is a large trilobite, reaching a length of . The body is oblong-oval, about twice as long as it is wide, It had a strongly convex profile, giving it its distinctive globular appearance. Like all trilobites, the body is divided into three functional segments known as Tagma (biology), tagmata (singular: tagma), which ...

Bojoscutellum
''Bojoscutellum'' is a genus of trilobites in the order Corynexochida family Styginidae. These trilobites were nektobenthic carnivores that lived in the Devonian period in the Eifelian The Eifelian is the first of two faunal stages in the Middle Devonian Epoch. It lasted from 393.3 ± 1.2 million years ago to 387.7 ± 0.8 million years ago. It was preceded by the Emsian Stage and followed by the Givetian Stage. North American ... age (395 million years ago).

Corynexochida
Corynexochida is an order of trilobite that lived from the Lower Cambrian to the Late Devonian. Like many of the other trilobite orders, Corynexochida contains many species with widespread characteristics. Description The middle region of the cephalon (arthropod anatomy), cephalon (the glabella) is typically elongate, with the sides often spreading forward (pestle-shaped). Some species have glabellae that are ''effaced'', meaning they are smooth and show little detail. The glabellar furrows (when not effaced) typically have a splayed arrangement. In most species, the hind pair on either side of the cephalon become spines that point sharply backwards, and the spinose tips of the anterior pairs of thoracic segments tend to become more and more forward directed toward the pygidium. The eyes are typically large. Pygidia are typically large, competing in size with the cephalon in some species. The tips of the thoracic segments of many Corynexochida species are spine-like (though in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
