3.7 out of 5 stars
Free Range Reading
I have developed many odd interests over the last 60 years. Paleontology has been a long lasting love. My father used to tell me that I knew the names of “all the dinosaurs" by the time I was three (an exaggeration I'm sure). In the last decade or so, I've also become fascinated with fossil fishes. Attendance at a lecture/slide show by the artist Ray Troll sparked my interest (check out his website for fabulous fin art).
Anyone who has read Peter Benchley's Jaws will understand the lure of the gigantic prehistoric shark Megalodon. Shark fossils are particularly scanty, as their skeletons are mostly cartilaginous rather than bone and cartilage doesn't preserve well in the fossil record. However it is amazing what scientists have been able to piece together from what there is available: range maps, possible birthing localities, diets, possible habits and causes of extinction (although the last two items seem rather more speculative).
The ocean is a mysterious place to most of us and its predators are a source of fascination. There is good reason that there are many shark gods envisioned by the people of Oceania. Our current world has an impoverished ocean, with sharks and other fish, whales, even corals and other small creatures in decline. Nevertheless, there are those who would like to believe that the Megalodon still lurks in the depths. I suppose anything is possible, but it seems to me that there just aren't enough food species left to maintain a sustainable population of this enormous shark. But I think it is natural, in a world where so many species teeter on the edge of extinction, to hope that this awesome predator is still out there.
I've read other books by Tim Flannery which I also found enjoyable. He provides accurate information (although paleontology is a science prone to revision as new specimens are studied) and he writes in a clear, accessible style. I get the impression that he truly loves sharing his knowledge. If you are particularly interested in fossil sharks, I would also recommend Resurrecting the Shark: A Scientific Obsession and the Mavericks Who Solved the Mystery of a 270-Million-Year-Old Fossil. If fossil fishes in general are your jam, The Rise of Fishes: 500 Million Years of Evolution might suit you. If you are intrigued by the connection between fish and land animals, Your Inner Fish: a Journey into the 3.5-Billion-Year History of the Human Body is a great choice.
