The divisions are not arbitrary: they reflect major changes in the dominant conditions and forms of life on Earth. The Cenozoic Era is marked by the rise of mammals, following the mass extinction of dinosaurs and most other plants and animals at the end of the Mesozoic. The Pleistocene Epoc...
Sohow did crocodiles manage to survive into the Cenozoic Era?Theory 1: Crocodiles Were Exceptionally Well-AdaptedWhereas dinosaurs came in all shapes and sizes-huge, elephant-legged sauropods, tiny,feathered dino-birds, towering, ravenous tyrannosaurs—crocodiles have stuck with pretty much thesame ...

How would you explain the Cenozoic evolution of the North American Cordillera in terms that a nongeologist could readily understand? If plate tectonic movement did not exist, could there be metamorphism? Explain how plate positions and climate influenced the geographic distribution...
the beginning of the Cenozoic (the era after the Mesozoic).Between the last layer of Cretaceous rock and the first layer of Cenozoic rock, there is often a thin layer of clay.Scientists felt that they could get an idea of how long the extinctions took by determining how long it took to...

lands to people with green eyes for centuries. When studying the geologic time scale; a tool used to measure our planets history, it is thought that green eyes may have appeared in people of Iranian, Spanish, Brazilian and Pakistani decent sometime during the late part of theCenozoic period....
