from The Century Dictionary.
- noun In geology, the most recent of the divisions of the Tertiary proper. See
Tertiary . Also spelledPleiocene . - noun It was the final period of Tertiary time, during which the distribution of land and sea was very much as it is now. The uptilted deposits of this age, which are of world-wide distribution, consist of mostly unconsolidated sands, clays, and marls of marine and terrestrial origin, containing invertebrate and plant remains very similar to those of the present. The vertebrate fauna, on the other hand, differs widely, with numerous extinct types of large size, among which Dinotherium, Mastodon, Elephas, Equus, Hippopotamus, Rhinoceros, and Machærodus were of gigantic proportions. The Pliocene of southern Europe has been divided into the following stages: lower, Messinian or Plaisancian; middle, Astian; upper, Arnusian or Sicilian. In North America, marine deposits of this age are represented by the Floridian series of the Gulf coast and the Merced and San Pedro series of the Pacific coast; and the terrestrial deposits by the Palo Duro and Blanco beds of Texas and Oklahoma.

The continuation stated that Elliot Smith — with whom Keith was to quarrel a year or so later — had made the most notable contribution to the meeting with his commentary on the "brain cast" that was given him by Smith Woodward, and that "the chief divergence of opinion" in the discussion related to the antiquity of the finds, with Sir Arthur Keith — mentioned by name — regarding them as earlier than Pleistocene and possibly Pliocene, that is to say, the age to which some of the planted fossil animal teeth may have belonged.
