Although they're very popular pets, many people mistakenly believe rabbits belong to the rodent family. Editors select a small number of articles recently published in the journal that they believe will be particularly The first fossil record of mammals with lagomorph-like characters is from the Paleocene Epoch (65 to 54.8 million years ago), a time during which many mammalian orders diversified.
