Where are Miocene fossils found?
Important Miocene deposits occur in North and South America, southern Europe, India, Mongolia, East Africa, and Pakistan. Both marine and terrestrial environments are represented in the Miocene stratigraphic record.
What are fossils of marine organisms found in many mountains?
Often fossils of marine organisms are found on or near tall mountains. For example, the Himalayas, the tallest mountains in the world, contain trilobites, brachiopods, and other marine fossils. This indicates that rocks on the seabed have been uplifted to form huge mountains.
What is the middle Miocene?
The Middle Miocene is a sub-epoch of the Miocene Epoch made up of two stages: the Langhian and Serravallian stages. The Middle Miocene is preceded by the Early Miocene. The sub-epoch lasted from 15.97 ± 0.05 Ma to 11.608 ± 0.005 Ma (million years ago). During this period, a sharp drop in global temperatures took place.
What ended the Miocene?
5.333 million years ago

Why are marine fossils found in mountains?
The fossils are believed to have traveled from the water to the hills by natural events such as earthquakes or tectonic plate shifts. California is no stranger to these events, and the state’s complex fault lines “ensure the earth is always moving [so] ancient rock is constantly being thrust to the surface.”
Why are marine fossils found near the top of Mount Everest quizlet?
Why are marine fossils found near the top of Mt. Everest? Tensional forces caused thinning of the lithosphere in the western United States which resulted in decompression melting in the mantle and the rise of magma.
What caused the middle Miocene disruption?
Cooling that led to the Middle Miocene disruption is primarily attributed to orbitally paced changes in oceanic and atmospheric circulation due to continental drift. …

Are Miocene apes rare?
Skulls of fossil apes and other close relatives of humanity are extremely rare, especially those of infants and young juveniles. This find is only the second relatively complete cranium of a young juvenile from the Old World during the entire Miocene, an epoch stretching from 5 million to 23 million years ago.
Why did so many species of apes go extinct during the late Miocene?
At the close of the Miocene, North America and South America are close enough for some species to cross the narrow dividing waters. Animals that go extinct in the Miocene more likely do so because they fail to adapt to changes in climate and vegetation.
What are the four types of fossils?
Four Types of Fossils Sort Packet A sort activity using the four types of fossils (mold, cast, trace, and true form).
What do you call someone who studies fossils?
Paleontologists use fossil remains to understand different aspects of extinct and living organisms. Individual fossils may contain information about an organism’s life and environment. Paleontologists study amber, called “fossil resin,” to observe these complete specimens.
