He may not be from the Pliocene Era, but his views sure are.
During the miocene and Pliocene ages, sessile cirripedes abounded.
Eocene, miocene, Pliocene Tuff, Lias and Trias and that is enough.
M. Dubois discovered these remains in the island of Java in andesite tufa of Pliocene or at least early Pleistocene age.
With the termination of the Pliocene Age we find ourselves on firmer ground.
The first thing which impresses us is the extremely fragmentary distribution of the Miocene and Pliocene beds.
The age of these gravels is, therefore, pronounced to be Pliocene.
We can see how well this agrees with the changes of climate at the close of the Pliocene Age.
The last two are Pliocene and American; the teeth are much reduced.
Crocodiles and alligators swarmed in the rivers of Europe until the chilly Pliocene bade them depart to Africa.
The fifth and last epoch of the Tertiary Period, from about 5 to 2 million years ago. During this time the global climate became cooler and the number and expanse of grasslands and savannas increased greatly. This change in vegetation was accompanied by an increase in long-legged grazers. The land bridge between North America and South America also formed at this time, and massive ice sheets accumulated at the poles. In the later part of the epoch many of the species living in polar regions became extinct. See Chart at geologic time.
