Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Mackenziurus johnnyi is a species of trilobite named after American musician Johnny Ramone. M. joeyi, M. deedeei, M. ceejayi were similarly named after members of the Ramones. In biology, a species is one of the basic units of biological classification and a taxonomic rank. A species is often defined as a group of organisms capable of interbreeding and producing fertile offspring. While in many cases this definition is adequate, more precise or differing measures are often used, such as similarity of DNA, morphology or ecological niche. Presence of specific locally adapted traits may further subdivide species into subspecies.
