The brown rat R. norvegicus is about 20 cm/8 in long with a tail of almost equal length. It is believed to have originated in central Asia, and is now found worldwide after being transported from Europe by ships. The black rat R. rattus, responsible for the plague, is smaller than the brown rat, but has larger ears and a longer, more pointed snout. It does not interbreed with brown rats. The pack rat or wood rat, genus Neotoma, is common throughout North America and there are seven different species. Their dens, made of partly eaten plants, dung, and miscellaneous objects, are known as middens and can be up to 2 m/6.5 ft across and 20–30 cm/8–12 in high. The rats’ crystallized urine preserves the midden, in some cases for up to 40,000 years.
