1903 A. J. Jukes-Browne in Geol. Mag. X. 37 The term hemera may, however, be occasionally convenient to signify the duration of a subzone, as age signifies the duration of a stage, but if we want to avoid confusion we must not speak of the hemera of a zone. For this another word should be coined..I would suggest that the Latin word seculum will furnish us with ‘secule’ which finds an actual French equivalent in siècle.

1933 W. J. Arkell Jurassic Syst. Great Brit. i. 21 Several hemeræ may be contained in one secule or zone-moment.

1956 Amer. Jrnl. Sci. 254 459 Schindewolf reasserts..his extreme view..that the zone as conceived by Oppel was a purely chronological notion and that the term zone should be used only as a time term (= secule).

1969 G. M. Bennison & A. E. Wright Geol. Hist. Brit. Isles ii. 23 A zone is defined as strata deposited during an interval of time (known as a secule or moment, though these terms are not widely used) throughout which a particular faunal or floral assemblage existed.
