The Přídolí
The Pridoli Epoch of the Silurian Period: 419 to 416 Mya
Silurian Grammar
The Silurian Subcommission of the International Stratigraphic Commission was one
of the first to complete its work.
Holland (1985).
Perhaps for that reason, among others, and for good or ill, the self-conscious
internationalism of later reports was omitted. Consequently, some of the
typographical conventions of the Silurian were retained. So, for example,
The first epoh of the Silurian is the Llandovery, not the "Llandoverian."
The Přídolí retains its original Slavic
transliteration in the Episodes issue officially nominating the global
stratotype section and point. Notwithstanding, it is usually written
"Pridoli." We will use the two interchangeably and somewhat
randomly.
The Přídolí
remains the only
epoch (series) which is not further subdivided into ages (stages). The
current (2008) ICS scheme for the
Carboniferous includes an
additional five epochs with only a single age; but we have declined to
adopt that usage.
Vertebrates
Land Plants
Assemblages containing Cooksonia, and other simple rhyniophytes are preserved in what were originally marine, nearshore, and occasionally in freshwater river deposits, at a number of localities around the margins of Euramerica (the so-called "Old Red Land "). Most fossils were of plants that had been transported by rivers away from the places where they grew, so their original habitats remain obscure. They are often associated with fragments of
eurypterids.
