Re: “did ya see any of that movement take place in yer vast lifetime? ”LOL - in my lifetime, the continents have moved a few feet closer or further from one another. That would require me to be one heck of a dedicated observer!

Think about this: Earth is around 4.6 billion years old. Oceans started forming early - 4.4 to 3.8 billion years ago - when temperatures cooled enough to allow water vapor to condense. Life appeared perhaps 4.1 billion years ago, with the oldest fossils we've dated being 3.5 billion years old. Continents (or A continent) formed 3.3 billion years ago or so. And the one supercontinent, Pangaea, broke apart just 200 million years ago.

When you view the timeline that way, 77 million years - when North America's geography was so different - is the virtual blink of an eye.

I have a 50 million year old Notogoneus osculus fossil hanging on my wall. Every time I look at it, I feel awe. The changes it must have seen! (Except, of course, for being dead nearly the whole time.)
