Reptilian Extinctions Over the Last Ten Thousand Years

The fossil record of the earth shows that faunal and floral extinctions increased dramatically during certain periods. These “paleo” upheavals like those at the end of Permian and Cretaceous have long provided the punctuations that geologists and paleontologists use to divide the geological periods. A challenging question in conservation science is whether the processes affecting extinction rates today are helpful in interpreting extinction in the past and, conversely, whether prehistoric extinctions are useful for understanding recent extinctions.
