The Cenozoic era, spanning from about 66 million years ago to the present, is often referred to as the "Age of Mammals" due to the significant evolution and diversification of mammals following the extinction of the dinosaurs. This era also saw the rise of birds and flowering plants, along with major geological changes that shaped the Earth's climate and landscapes. It is characterized by the development of modern ecosystems and the emergence of humans in the late stages. The Cenozoic is divided into three periods: the Paleogene, Neogene, and Quaternary.

What ancient environment is the most likely inferred by the large rock salt deposits in Syracuse New York area?

What are three division of the phanerozoic Eon?
The Phanerozoic Eon is divided into three major eras: the Paleozoic, Mesozoic, and Cenozoic. The Paleozoic Era is characterized by the emergence of diverse marine life, the colonization of land by plants and animals, and significant geological changes. The Mesozoic Era, often referred to as the "Age of Reptiles," is known for the dominance of dinosaurs and the development of mammals and birds. The Cenozoic Era, the current era, is marked by the rise of mammals, birds, and flowering plants, as well as significant climatic changes.
What animals lived in the paleozoic era?
Not Extinct Through out the Cenozoic era, the oceans were home to nearly the same invertebrate animals as today. Foraminifera were common as well. Sponges, coral, starfish, seaurchens, and sand dollars were common as well Brachiopods and cephalopods were rare. Mollusksclams, oysters, mussels, and snails- thrived through out the era. Crabs and barnacles were common as well. A land, the spiders, centipedes, scorpions, and insects continued to thrive. Insects including butterflies, moths, bees, wasps, ants, beetles, and many others. Most Cenozoic fish were like that of late Mesozoic time. Sharks and rays were abundant and gigantic. Some sharks were 20 meters long with jaws nearly 2 meters wide. Amphibians, such as frogs, toads, and salamanders, were about as common as they are now. The reptiles-turtles, lizards, snake, and crocodiles- resemble those of today. Birds developed that were similar to those of today. At times, there were many large, flightless, ostrich like types. Some were three meters tall. Extinct Creodonts, oreodons an early grazing animal that resembles a deer, the mastodon a kind of gigantic elephant, brontotherium a gigantic rhino like animal, blachitherium rhino like animal , armadillo a gigantic sloth like animal. These are just some of the animals that lived in the Cenozoic era that are now extinct.
What caused many events of mountain building volcanoes and earthquakes in western north America during the Cenozoic?
During the Cenozoic era, the events of mountain building, volcanic activity, and earthquakes in western North America were primarily caused by the complex interactions of tectonic plates. The subduction of the Juan de Fuca and Pacific Plates beneath the North American Plate led to significant volcanic activity and the uplift of mountain ranges like the Cascades. Additionally, the movement of the San Andreas Fault system contributed to frequent earthquakes and further geological instability in the region. These tectonic processes were driven by the ongoing dynamics of plate tectonics in the area.

In what era do humans appear?
Cenozoic
In which geologic era did humans appear?
Humans appeared during the Quaternary period of the Cenozoic era, which began around 2.6 million years ago. This era is marked by the development of modern human species and the emergence of Homo sapiens.
