Hi science with Thomas, I'm homeschooled and my work today is about the geological timescale, my mum said I should watch this video as part of my work and its really good. Thanks for the great video :-D

Thank you for this video @Science with Thomas Stevenson. I want to be a paleontologist in the future, so this really helped jogging my memory. Love from Fairmont High School.

How are index fossils used to identify the subdivisions of the geologic time scale?

[majorfunnycontents]

could answer this question please

1. Describe how to read and analyze the geologic time scale, name the four major divisions, and describe any other helpful details to understanding the time scale.


2. How did scientist name each time period? What artifacts contributed to naming these periods? Give 2 examples of types of artifacts used.





3. Describe three major time period and events that happened during those times. (ex dinosuar extinction/ humans appear)





4. Give the names of the 4 major ERA's that appear in the geologic time scale, and list them in chronological order (oldest to most recent).

The Precambrian is a Super eon not a period

You are young, intelligent and interested in stratigraphy and you never doubted the story that Hutton and Lyell made up? All over the world we find evidence for the opposite choice: catastrophism. The present theory is that one layer is formed underwater in more than 100, 000 years. In reality, five layers are formed within a cycle of 25, 200 years. The cause of every layer is the crossing of a celestial body close to our sun and its planets. five out of seven crossings cause a huge tidal wave that is pulled all over the planet. It leaves a thick mud layer, a mix of sand, clay, lime, fossils etc. but also a deposit of the enormous reddish dust cloud that is surrounding that celestial body and that dust is extraterrestrial, so contains no organic material and it is very old. In fact you find that same old deposit in every layer. That confuses geologists. The approaching planet is depicted in many ways in stone, cylinder seals, petroglyphs and sand paintings. That planet was seen and depicted just before our era and deposition of that dust cloud was found in the ice layer of Greenland. In the e-book: "Planet 9 = Nibiru". we explain a lot about this cycle and its consequences. This book contains many pictures to explain what knowledge is present on our planet.
