Trilobite superfamilies

The ”Fallotaspidoidea” are a superfamily of trilobites, a group of extinct marine arthropods. It lived during the Lower Cambrian (Atdabanian) and species occurred on all paleocontinents except for the Gondwana heartland (currently Latin America, most of Africa, Australia, Antarctica, India and China). A member of this group, Profallotaspis jakutensis, has long been the earliest known trilobite, but recently the redlichiid Lemdadella has been claimed as occurring even earlier.

Trinucleioidea is a superfamily of trilobites. Traditionally placed within the Asaphida, it is now sometimes considered its own order, Trinucleida. thumb|Damghanampyx ghobadipour fossil from Lashkark Formation, Ordovician, Damghan, Iran
