WHY DIDNT CROCODILES, TURTLES, LIZARDS, AND OTHER ANCIENT ANIMALS DIE OUT WHEN THE DINOSAURS DID?
No one really knows for sure. In fact, it is not entirely clear what caused the extinction of the dinosaurs and some of their contemporaries. The most popular explanation for this extinction is that a comet or asteroid slammed into the Yucatan Peninsula 65 million years ago. In addition to the immediate destruction caused (impact, wildfires, and tsunamis), such an impact would have thrown a huge amount of dust and debris into the atmosphere, which would block out the sun for an extended period of time and prevent photosynthesis. This would cause the death of many plants, and in turn, the animals that relied on them. Although there is geologic evidence that such an impact did occur, it does not answer all the questions surrounding the extinction event. There may have been other, multiple causes for the extinctions, which are difficult to identify. In fact, some paleontologists believe that dinosaurs were already scarce and disappearing prior to any impact. Changes in climate and mountai
