"Fenner azoic is divided up into three eras the paleozoic the mesozoic and the senate zoellick the first period in the paleozoic is the one you might have heard of the cambridge in the cambrian is noted for the sudden appearance of complex lifeforms and animals in the fossil record. This is known as the cambrian explosion. Here's where you'll see many of the trial bites which are really common fossils in fact the appearance of trial bites pretty much defines where the cambrian appears in the geologic record all complex life that we know of in the cambrian was in the see.

This is the first of the major extinction events in earth's history and the second largest in terms of the number of species that disappeared from the fossil record.

"fenner azoic" Discussed on Everything Everywhere Daily

"Is so old that to make sense of its history. Geologists have come up with divisions these divisions are very broad and cover millions to billions of years depending on what the division is each division also has subdivisions that they themselves can be further subdivided. The three primary temporal divisions of earth's history are eons eras periods and eon is a very broad definition of history. And there's only been three eons your can which goes from the formation of the earth to about two point five billion years ago the protozoa which goes from two point five billion years ago to about five hundred and forty million years ago and the phanor azoic which goes from five hundred forty million years ago to today. There's also sometimes a fourth theon called dan. Which would have been the formation of the earth to about four billion years ago. But it's really hard to study that period by itself. so it's often just lumped with european. I actually studied geology and geophysics for several years and the use of eons seldom came up. Occasionally you hear about the arkin but other aeons are so broad that they're just generally not useful the are. Ken is the period where the continent started to form. The very simplest life began the protozoa. Eon where oxygen appeared in the atmosphere and up to the beginning of complex multicellular life in your ken and the protozoa. There is little to nothing in the way of fossils because there was nothing. That could be fossilized yet. There are some fossilized dramatic light beds which were mats of bacteria. But that's about it. The rest of this episode will focus on the fan zoecke on. That's where most geologic research is done. And it's where all the fossils are. The fenner azoic is divided up into three eras the paleozoic the mesozoic and the senate zoellick the first period in the paleozoic is the one you might have heard of the cambridge in the cambrian is noted for the sudden appearance of complex lifeforms and animals in the fossil record..
