Looking Deep into the Past

Posted at 3:43 pm under Blog Post

A few days ago, I revisited Fisk Quarry in Isle la Motte, where there are all kinds of marine fossils in full view. Then I stopped by the Goodsell Ridge Preserve to see even more fossils etched into stone over immense periods of time. I’ve been reading a lot of natural history recently and wanted to look with my own eyes deep into the past. After all, seeing is believing.

The fossils didn’t exactly jump out at me. At first all I saw were strange shapes in the rock that seemed more like hallucinations than anything real – projections of my own thoughts onto stone. But when I reached down and touched them, yes, that made them very real.

Gastropods, cephalopods, stromatoporoids, bryozoa – the names of these ancient creatures are as strange to me as what I was seeing. Or at least they were. But if you say such names frequently enough they become commonplace. The brain makes room for them, and for what they represent.

Chazy Reef it is called. Not a reef in the strictest sense, since the mound of life forms that built up there over time contained only a smattering of corals. It dates back 480 million years, and was located back then where Africa is today. The tectonic plates of the Earth’s crust move a couple inches each year, so now Chazy Reef is in Vermont. Pondering that alone is enough to make my head explode.

480 million years… That’s a long time. Back then marine life was all the life there was. Amphibians, reptiles, and land-loving mammals like us came along much later. It’s difficult to fathom that passage of time, and even more difficult to think of the natural world as something much different from what it is now. We take so much for granted. But this world of ours, all the stars and galaxies, the entire universe has been evolving for 14 billion years. And it will continue evolving long after you and I are gone. That certainly puts things in perspective.
