from 13 million to 2 million years ago; growth of hills; air conditioning of climate; many larger animals
it absolutely was the ultimate period of Tertiary time, during which the distribution of land and water was very much because it's now. The uptilted build up for this age, that are of world-wide circulation, consist of mainly unconsolidated sands, clays, and marls of marine and terrestrial source, containing invertebrate and plant stays nearly the same as those associated with present. The vertebrate fauna, alternatively, differs commonly, with many extinct kinds of large-size, among which Dinotherium, Mastodon, Elephas, Equus, Hippopotamus, Rhinoceros, and Machærodus were of gigantic proportions. The Pliocene of south Europe has-been divided into the following stages: lower, Messinian or Plaisancian; middle, Astian; upper, Arnusian or Sicilian. In North America, marine build up with this age tend to be represented because of the Floridian a number of the Gulf coastline together with Merced and San Pedro variety of the Pacific coast; as well as the terrestrial deposits by the Palo Duro and Blanco bedrooms of Texas and Oklahoma.
In geology, the most recent for the divisions regarding the Tertiary proper. See Tertiary. Also spelled Pleiocene.
Of, related to, or characterizing, the newest division for the Tertiary age.
Of a geologic epoch in the Neogene duration from about 5.3 to 1.7 million years ago; marked by the appearance of people's first ancestors.
Of or from the geologic time, stone series, or sedimentary build up associated with the last epoch regarding the Tertiary stage, described as the look of distinctly modern pets. See Table at geologic time.
