Tertiary feather, in ornith. see TERTIARY, n.-Tertiary formation, in geol. the third great division of stratified rocks, lying immediately above the secondary. The earlier geologists used this term as designating all strata above the secondary; but later discoveries have tended to modify its sense by way of restriction. As now employed the term tertiary formation designates the rock-system extending from the chalk (the highest member of the secondary), on which it rests, to the base of the posttertiary system, which latter, according to some, includes the strata belonging to the glacial epoch, while others leave them in the tertiary. It is noteworthy that there is a complete and entire physical break between the rocks of the secondary or mesozoic and tertiary periods, the latter resting in no instance conformably on the former, while there is an equally complete break in the life of the two periods, not a single secondary animal or plant being known to have survived the cretaceous period with the exception of a few Foraminifera. In the tertiary rocks, on the other hand, not only are all the animals and plants more or less like existing types, but we meet with a constantly increasing proportion of living species as we pass from the bottom to the top. The classification of the tertiary formation is based on this increase, the strata being divided into two great groups as follows:-(1) The OLDER TERTIARY, comprising the Eocene, with five per cent of living species, and the Miocene, with twenty-five per cent. (2) The NEWER TERTIARY, comprising the Older Pliocene, containing fifty per cent of living species, and the Newer Pliocene, containing ninety-five per cent. Tertiary (ter'shi-a-ri), n.
