Is limulus a living fossil.?
Limulus is an ancient genus which has probably existed since the Silurian period (440 to 410 million years ago), and shows little morphological change from the now extinct genus Paleolimulus that lived about 200 million years ago. Limulus polyphemus is believed to be the closest living relative of trilobites (Shuster 1982).
