I kind of ripped off LiveScience's headline, but couldn't resist. Paleontologist Steve Sweetman looks for, and finds, new species that other visits to the fossil-heavy Isle of Wight have missed. His methord? Digging out, drying, and sifting through tons of sand for small teeth and bones. That seems mind-numbing to most of us, but Sweetman is encouraged every time he hits a new species of reptile or amphibian - and he has 48 so far.
