An example to quantitative determination of species in paleontology an application in the icriodus lineages of the lower devonian

, : An example to quantitative determination of species in paleontology an application in the icriodus lineages of the lower devonian. Turkiye Jeoloji Kurumu Bulteni 29(1): 73-80

Through the application of some statistical analyses to the abundant Icriodus specimens, Lower Devonian conodonts, collected from the Monitor and Toquima ranges, Central Nevada, U.S.A., the evolutionary change in this fossil group is investigated. Under the light of ontogenetic concepts and observations, the statistical frequency distributions of elongation index in the populations, which is modified from width-length ratio as I-W/L, are evaluated mathematically. By the interpretations concerning evolution and taxonomy, the two species. I. steinachensis and I. claudiae are redescribed and the hypodigms of the two are given. Mathematical methods, graphs, and interpretations are explained in detail.

The nucleotide sequences of genome segments S7 and S10 of a Thai-isolate of nice ragged stunt virus (RRSV) were determined. The 1 938 bp S7 sequence contains a single large open reading frame (ORF) spanning nucleotides 20 to 1843 that is predicted...
