In the geologic timescale, the Přídolí Epoch (Czech pronunciation: [ˈpr̝̊iːdoliː]) is the uppermost subdivision of the Silurian Period, 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, the lowest of three stages within the Lower Devonian geological epoch. It is named after one locality at the Homolka a Přídolí nature reserve near the Prague suburb, Slivenec, in the Czech Republic.^[7] The GSSP is located within the , overlying the . Přídolí is the old name of a cadastral field area.^[8]
