Receptaculites is the name-bearing genus for a group of conspicuous benthic marine genera the Receptaculitidae that lived from the Early Ordovician through the Permian peaking in the Middle Ordovician. The group’s phylogenetic origin has long remained obscure but current understanding indicates that the Receptaculitidae were probably calcareous algae of the Order Dasycladales.
