Geologica Acta, 2005 The systematic analysis of conodonts from the previously unstudied Mithaka Formation (Georgina Basin) yielded 1366 identifiable elements, representing 25 species and 21 genera. One new species was recovered and identified, Triangulodus mithakensis n. sp.

The Anatomical Record, Volume 309, Issue 3, Page 550-602, March 2026.Abstract Actinopterygii is a major extant vertebrate group, but limited data are available for its earliest members. Here we investigate the morphology of Devonian actinopterygians, focusing on the lower jaw. We use X‐ray computed tomography (XCT) to provide comprehensive descriptions of the mandibles of 19 species, which span the whole of the Devonian

Conodont biostratigraphy in the Middle–Upper Ordovician boundary beds of Estonia [PDF]
Estonian Journal of Earth Sciences, 2008 Conodonts of the uppermost Uhaku, the Kukruse, and the lower Haljala stages (uppermost Darriwilian and lower Sandbian) of Estonia are discussed. The distribution of conodonts within the Pygodus serra, P.

Conodont dating of some Telychian (Silurian) sections in Estonia [PDF]
Estonian Journal of Earth Sciences, 2008 Several Telychian–Sheinwoodian strata exposed in Estonia are precisely dated using conodont biostratigraphy. The beds in the Valgu-1 section correspond to the uppermost Distomodus staurognathoides and Pterospathodus eopennatus ssp. n. 1 zones.

Polytaxonomic and monotaxonomic zonal biochronological scales in biostratigraphy
Литосфера, 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
