    Dynamics of Silurian Plants as Response to Climate Changes by Josef Pšenička, Jiří Bek, Jiří Frýda, Viktor Žárský, Monika Uhlířová, Petr Štorch

    Published 2021-08-01
    “…However, available palynological, phylogenetic and geological evidence indicates that the history of plant terrestrialization is much longer and it is recently accepted that land floras, producing different types of spores, already were established in the Ordovician Period. Here we attempt to correlate Silurian floral development with environmental dynamics based on our data from the Prague Basin, but also to compile known data on a global scale. …”

    Kordonka Terrane — a fragment of the Early Paleozoic active margin by Golozubov V.V., Malinovsky A.I., Chashchin A.A., Kandaurov A.T., Khubanov V.B., Kasatkin S.A., Zheldak M.V., Orudzhev T.V.

    Published 2021-12-01
    “…The Devonian granitods first identified in this area may be evidence of the Kordonka block accession to the Bureya-Jiamusi-Khanka orogenic belt consolidated during the Ordovician. The Kordonka terrane thus marks an independent Early-Middle Paleozoic episode in the formation and closure of the Central Asian paleo-ocean.…”
