geotimescale enhanced

I love crib sheets and this one is terrific. It clearly maps out the time scale of the history of the planet. It gives the names and lengths of its periods and a brief description of why they begin and end when they do. Whether you are reading about the evolution of whales, trilobites, stromatolites or dinosaurs it give a quick and easy perspective of when your subject lived. It is better than a book because it is always in your pocket.

I have only come to appreciate geology in the past couple years. I find fascinating the processes God created to continually grow/develop the landscape of our planet! I wish I had more time toward more. Thanks to this app I am learning each if the ages, Life during each age, etc. this is very insightful and easy-to-use. THANK YOU, TASA, for creating geotimescale!

I bought this app because I can never keep those geologic eons, eras, periods and epochs straight. I'm not a geologist, but I'm interested in the history of the earth and have been reading some good books about it lately. This app is an enjoyable way to keep it all straight. The paid app was well worth it because of the included drawings and descriptions of the epochs. The pictures bring the epochs to life, and are much more memorable than the names.

Only shows the timescale. Based on the description would thing there was additional information - nothing, just a timescale. You can get this exact information for free in a book or google it, don't waste your money.
