Humans originated in the Pleistocene, but did not become a dominant or influential species until the Holocene. The Eocene saw the rise of horse and dog species in North America.
The Eocene Epoch, lasted from 56 to 33.9 million years ago. There is no such thing as the "lower Eocene period"!
No. The dinosaurs rose in the Mesozoic era. The end of the Mesozoic era was also the end of the dinosaurs. The era following is the Cenozoic, which we are still in today.
It is currently believed that the first Artiodactyls lived in the Early Eocene epoch 55 million years ago.
The first sand dollars formed during the period Paleocene. After that they diversified during the Eocene period.
The Paleogene Period followed the Cretaceous.
The tiny tribe(s) that survived against almost impossible odds to evolve into humans.
The dominant animal of the Eocene Epoch was the early mammals, which included large herbivorous mammals like the brontotheres and early primates. This period marked a significant diversification and expansion of mammalian species in response to the changing environment.
The period where whales first appeated is to be during the Eocene Epoch (56-34 Million Years Ago).
No
A basilosaurus is any of a group of very large extinct cetaceans of the family Basilosauridae, from the late Eocene period.
The Tertiary Period (including the Pliocene, Miocene, Oligocene, Eocene, and Paleocene Epochs) lasted from about 65 million years ago to 1.8 million years ago. It is part of the Cenozoic Era, along with the Quarternary Period.
Not likely dogs and cats are intellegent but are not able to evolve like humans do.
