Proterozoic EonThe Proterozoic Eon extended from 2500 mya to 541 mya (million years ago), and is the most recent part of the Precambrian “supereon.” The Proterozoic is the longest eon of the Earth’s geologic time scale and it is subdivided into three geologic eras (from oldest to youngest): the Paleoproterozoic, Mesoproterozoic, and ….
What is the current eon?
The Phanerozoic Eon is the current geologic eon in the geologic time scale, and the one during which abundant animal and plant life has existed. It covers 541 million years to the present, and it began with the Cambrian Period when animals first developed hard shells preserved in the fossil record.
What era and period are we?
1 Answer. We live in the Holocene Epoch, of the Quaternary Period, in the Cenozoic Era (of the Phanerozoic Eon).
What are the 3 eons?
Three eons are recognized: the Phanerozoic Eon (dating from the present back to the beginning of the Cambrian Period), the Proterozoic Eon, and the Archean Eon. Less formally, eon often refers to a span of one billion years.
How old is an eon?
about a billion yearsEon goes back to the Greek aiōn, “age.” An age is not easy to measure, and neither is an eon. Both are just really long periods of time, but in science an eon is about a billion years.
What is the oldest era?
Paleozoic EraThe oldest is the Paleozoic Era, which means “ancient life.” Fossils from the Paleozoic Era include animals and plants that are entirely extinct (e.g., trilobites) or are rare (e.g., brachiopods) in the modern world.
What is a relative age dating?
Relative dating is the science of determining the relative order of past events (i.e., the age of an object in comparison to another), without necessarily determining their absolute age (i.e. estimated age).
Is Eon a Scrabble word?

What is today’s age called?

What was the dinosaur era called?
Mesozoic EraThe ‘age of dinosaurs’ (the Mesozoic Era) included three consecutive geologic time periods (the Triassic, Jurassic, and Cretaceous Periods). Different dinosaur species lived during each of these three periods.
How long is an eon in geologic time?
In Astronomy, an eon refers to 1 billion ( 109 ) years. But it also refers to a very long, unspecified period of time, or specific geologic stages of the Earth.
What are the 4 eons?
The eon is the broadest category of geological time. Earth’s history is characterized by four eons; in order from oldest to youngest, these are the Hadeon, Archean, Proterozoic, and Phanerozoic.
What era do we live in?
CenozoicOur current era is the Cenozoic, which is itself broken down into three periods. We live in the most recent period, the Quaternary, which is then broken down into two epochs: the current Holocene, and the previous Pleistocene, which ended 11,700 years ago.
What does EON stand for?
