Asaphus holmiDescription: A well-inflated example of an uncommon Asaphid, this is Asaphus holmi. The white limestone matrix complements the golden calcite exoskeleton. It is distinguished from its contemporary, Asaphus cornutus, by virtue of the more rounded shape of the cephalon and pygidium. It has a lifelike pose, as if crawling across its nearly half billion year old seafloor matrix.
