Ages of the Pridoli epoch.
Axis scale: millions of years ago.

In the geologic timescale, the Přídolí epoch, uppermost subdivision of the Silurian period is dated at between 423 ± 2.3 and 419.2 ± 3.2 mya (million years ago). The Přídolí epoch succeeds the Ludfordian Stage and precedes the Lochkovian, lowest of three Stages within the Lower Devonian geological period. It is named after one locality at the Homolka a Přídolí nature reserve near the Prague suburb, Slivenec, in the Czech Republic.[1] Přídolí is the old name of a cadastral field area.[2]
