Hansen and Holmer reported a diverse brachiopod fauna from the Lower and Middle Ordovician (late-Floian to mid-Darriwilian) of Spitsbergen bearing strong generic affinities with faunas from the rest of Laurentia. However, at species-level the Spitsbergen fauna is dominated by local endemics, with only 13 from 60 species found elsewhere in North Cited by: 7.

a Silurian (Geol) Of or pertaining to the country of the ancient Silures; -- a term applied to the earliest of the Paleozoic eras, and also to the strata of the era, because most plainly developed in that country.
☞ The Silurian formation, so named by Murchison, is divided into the Upper Silurian and Lower lower part of the Lower Silurian, with some underlying beds, is now. The passage from Cambrian to Ordovician was gradual, without any marked physical break. Only where the Upper Cambrian is sandy, as in New York, is there a decided change in the character of sedimentation.
In the latter part of the Cambrian a great inland sea had been established over what is now the Mississippi valley and, with frequent fluctuations in depth and modifications in form, it was. The name was introduced by C.
Lapworth in to embrace those rocks - well developed in the region formerly inhabited by the Ordovices - which had been classed by Sir R. Murchison as Lower Silurian and by A. Sedgwick in his Cambrian system. The term is convenient and well established, but Lower Silurian is still used by some authors.
