Very warm - extensive global warming caused naturally made the temperature much hooter than it is today. In fact the c02 levels were three to five time higher then they are today. Picture tropics near the north and south poles.
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.
Not sure what era but fossils of cats were found that dated back to the Eocene period. Cats came around in the 19th century.
An anoplotherium is a member of the extinct genus Anoplotherium, an ungulate known to have lived from the Late Eocene era to the Early Oligocene.
The Eocene Epoch, lasted from 56 to 33.9 million years ago. There is no such thing as the "lower Eocene period"!
The Cenozoic era is subdivided into two periods: the Paleogene and the Neogene. The Paleogene includes the Paleocene, Eocene, and Oligocene epochs, while the Neogene includes the Miocene and Pliocene epochs.
The Paleogene Period followed the Cretaceous.
Mesozoic Era
The Miocene was from about 26 million to 5 million years ago. It is part of the Tertiary Period and the Cenozoic Era. The word Miocene comes from the Greek for "less than present." It is the age of the first hominids.
The Cenozoic Era is divided into seven epochs: the Paleocene, Eocene, Oligocene, Miocene, Pliocene, Pleistocene, and Holocene. The Paleocene marks the beginning of the era, followed by the Eocene, known for the rise of mammals and flowering plants. The Oligocene features further mammalian diversification, while the Miocene and Pliocene epochs see the evolution of modern flora and fauna. The Pleistocene is characterized by ice ages, and the Holocene represents the current epoch, beginning approximately 11,700 years ago.
THE ANSWER IS EOCENE
very late cretaceous to eocene
Paleozoic Era: Cambrian, Ordovician, Silurian, Devonian, Carboniferous, Permian. Mesozoic Era: Triassic, Jurassic, Cretaceous. Cenozoic Era: Paleogene (Paleocene, Eocene, Oligocene), Neogene (Miocene, Pliocene), Quaternary (Pleistocene, Holocene).
