Which epoch does the oldest fossil bat come from?
The oldest fossil bat comes from the Eocene of Wyoming.
What are facts about the eocene epoch?
sharks n stuff were driven away from antarctica cause it was all turning to ice. :)
How many millions of years ago did the eocene epoch start?
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.
What are the different era?
Modern dating techniques have given a range of dates as to when the various geologic time periods have started, as they are listed below: Cenozoic Quaternary Holocene 10,000 years ago Estimated millions of years: Pleistocene 1.9 Tertiary Pliocene 6 Miocene 25 Oligocene 38 Eocene 55 Paleocene 65 Mesozoic Cretaceous 135 Jurassic 200 Triassic 250 Paleozoic Permian 285 Carboniferous (divided into 350 Mississippian and Pennsylvanian periods by some in the U.S.) Devonian 410 Silurian 425 Ordovician 500 Cambrian 570 Precambrian Proterozoic 2500 Archeozoic 3800 Azoic 4600
What period was after the cretaceous?
The period after the Cretaceous is the Paleogene period, which is part of the Cenozoic era. It includes the Paleocene, Eocene, and Oligocene epochs.

When was the lower Eocene period?
The Eocene Epoch, lasted from 56 to 33.9 million years ago. There is no such thing as the "lower Eocene period"!
What is the time of the mammals?
THE ANSWER IS EOCENE
What is the opposite of the ice age?
The geo-historic opposite of the Ice Ages (maximum glaciation) would be the periods of higher temperatures such as the Cretaceous Thermal Maximum (65 to 100 million years ago) and the Paleocene-Eocene Thermal Maximum (peaking about 55 million years ago).
What is the definition of Eocene?
Eocene comes from the Greek words meaning "dawn of the present." It is the age of the first large land mammals.

What was the dominant animal of the Eocene Epoch?
The Eocene Epoch was the second epoch of the Tertiary Period. During this time, mammals were the dominant form of animal life.

Minerals found in Jamaica?
Tertiary limestones cover more than 70% of the surface geology of Jamaica. Pre-Tertiary rocks are exposed in Cretaceous 'inliers' scattered over the island dated sedimentary rocks are Albian limestones and a Late Cretaceous to Recent stratigraphic succession is exposed on the island. Metamorphic rocks of greenschist and amphibolite facies derived from greywackes and volcanogenic sediments are probably Cretaceous in age. Most of the Early Cretaceous (Valanginian to Aptian) comprises rudist-bearing limestones, lava flows and volcaniclastic conglomerates, sandstones and shales. The Campanian to Maastrichtian of western Jamaica is represented by interbedded sandstones and shales more than 2000m thick, with minor conglomerates and thin limestones. Lava flows, volcaniclastics and limestones of equivalent age are present in central and eastern Jamaica. Tertiary stratigraphy is marked by a gradual upward transition from clastic to carbonate sedimentation. Paleocene to Early Eocene sections over Jamaica are characterised by clastic sedimentation. A reduction in clastic input gave rise to the impure Yellow Limestone Group of Early - Middle Eocene which grades upwards into the pure cherty micrites and sparites of the White Limestone Group (Middle Eocene - Middle Miocene).
