Exempel på hur man kan använda FLOIAN i en mening

• The earliest evidence for possible glaciation comes from Floian conodont apatite oxygen isotope fluctuations, which display a periodicity characteristic of Milankovitch cycles and have been interpreted as reflecting cyclic waxing and waning of polar ice caps.
• The Cyrtometopinae were present between the Floian and the Upper Katian, enveloping 22 species in 5 genera, of which the monophyly is unclear.
• elizae has been collected in the Lower Ordovician of Morocco (highest Tremadocian to mid Floian, Zagora region), the Upper Ordovician of Scotland (Starfish Bed of the Drummock Group, Dicellograptus anceps-zone, Thraive Glen, Girvan, Ayrshire).
• Discovered in the Floian strata of Newfoundland, coral-like fossils of Reptamsassia divergens and Reptamsassia minuta are the oldest example of symbiotic intergrowth of modular species.
• They first appear late in the Early Ordovician (Cassinian Stage, late Floian) with the Georginidae but don't become well established until the beginning of the early Whiterockian Stage (Dapingian) of the Middle Ordovician (Flower 1868,1976).
• In worldwide terms the Cassinian is upper, or late Arenigian which is exactly equivalent to the newly proposed Floian, both spanning the same 6.
• Stratigraphically productive layers are found through a -thick column of rock that spans the Tremadocian and Floian epochs.
• The Pterygometopidae are a family of trilobites, that is known from the Floian to the Katian (Ordovician), and reappears from the Telychian to the Sheinwoodian (Silurian).
• The subfamily Endymioniinae occurred from the Floian or possibly from the Lower Tremadocian to the Upper Katian and contains 36 species in 13 genera.
• Spihonotretids were most abundant in the late Cambrian and Early Ordovician (Furongian to Floian), and were traditionally considered to have gone extinct in the Upper Ordovician ("Ashgill").
