The defining characteristic of deserts is _____. The only fossils found were clearly already kangaroo rats and these almost certainly formed after the Flood.11 There are 59 species in the kangaroo-rat family, which includes so-called “pocket mice”.

The kangaroo rat looks like a mouse-sized kangaroo with very large back feet for leaping quickly away from predators. ; pocket mice: Perognathus spp. The other common species of kangaroo rats are smaller.
