Geologists have made a timeline of events, which we call the Geologic Time Scale, that help us understand the order of important geological events relative to one another in the billions of years of Earth’s history.The Devonian is the time (416 – 359 million years ago) when fish with jaws began to diversify and control the waters.In order to understand anything about the Devonian age of New York, we must put it into context with the rest of the Earth’s long history, using the concept of Deep Time.Deep time is the idea that the Earth has been in existence for 4.6 billion years, and throughout this time it has undergone many transformations.The way it appears today, with continents, mountains, oceans, and glaciers, is a reflection of how it has changed in the past.Unlike human history, where we think of events as having happened hundreds or thousands of years ago, in geology we must think in millions and hundreds of millions of years ago.New York’s Finger Lakes region has some of the best Devonian aged (416 to 359 million years old) rocks in the United States, and their exposure as a result of gorges and erosive waterfalls bring tourists of all ages and from all over the world.

I attempt to explain basics of the theory of evolution and correct many of the misconceptions.In the 1930s, oil was found in Devonian sandstones in the Ural-Volga region and later in the Pechora area of northern European Russia.In 1947 oil was discovered in an Upper Devonian reef at Leduc, Alta., Can.; this was followed by vigorous exploration, and oil production from the area remains significant today.Also during the Devonian Period, Gondwana began impinging upon Laurussia.There is evidence that these two landmasses completely fused together during the Late have been produced from Devonian rocks in New York and Pennsylvania.
