The Frasnian-Famennian mass killing event(s), methods of identification and evaluation [PDF]

open access: yes
The absence of an abnormally high number of earlier Devonian taxa from Famennian sediments was repeatedly documented and can hardly be questioned. Primary recognition of the event(s) was based on paleontological data, especially common macrofossils. Most

Polytaxonomic and monotaxonomic zonal biochronological scales in biostratigraphy

open access: yesЛитосфера, 2016
The method of increasing the correlation potential of zonal biochronological scales by creating the polytaxonomic complex characteristic of zone subdivisions is proposed. For this operation is necessary the normative zonal scale, by which biozones of the
