This book was my uncle Bruce's. I'm pretty sure it's also one of the last books I shelved (besides the Christmas books which is why it's out of order). It was an interesting read. The book itself is pretty old (older than Page Museum), and there were a lot of times I was left wondering how scientists decided what an animal ate or how it ended up in the tar pits. So it was slightly unsatisfying on that front, but overall not a bad book. It would be interesting to read a newer book about the tar pits to see if anything has changed.
