Seriously - is that even a book??
Not only that -- but I owned it! It was 19 cents at K-Mart. And I don't mean that it was, like, 19 cents at, like, K-Mart -- I mean it was actually 19 cents at an actual K-Mart. I bought it when I was a little kid because it was chock-full of tiny, grainy B&W photos of, you guessed it, trilobites and this was way before the internet and trilobites were so cool and where else could you see hundreds of photos of them? I remember wondering if every country had its own local guide to Ordovician trilobites or if this was something that fostered Argentinian destination travel. "Eat our beef; see our trilobites!"
My Dad (gently) teased me about this book for decades. To think that someone spent half their life creating this opus only to have it sell for 19 cents. (The photo above was from a listing for $45 on Amazon, so I should have cornered the market back when I had the chance.)
