DeepTime for Geology1.14 - App Store

DeepTime puts geological time at your fingertips. DeepTime is a full interactive version of the latest geological time scale: tap on any time unit to see more detail about it, including how its GSSP (golden spike) is defined. It even has the CMYK and RGB color codes for every time unit, great for when you need to have the right color for a map or chart. Even more, it is completely searchable by name or age. Come across an unfamiliar time term in an older paper? Search for it, and you'll see how it relates to the modern time scale.

What's more is that all the GSSPs (the golden spikes) are shown on a gorgeous geological map of the world (courtesy of macrostrat.org), which shows their context in stunning detail. Tips for using time terms are also included with simple examples. Whether you are a geologist, a student, a science writer, or just a fan of Earth history, DeepTime will become your go-to resource for understanding geological time.
