The Archaeocyatha was generally a shallow water tropical group.
Fossils are nearly always found with photosynthesizing
possibly symbiotically, and thus the group is thought to have lived within the
photic zone. The distribution of archaeocyath fossils and the characteristics
of the strata that contain them suggest that the group was largely restricted
to warm shallow waters near the equator. Although not as massive as reefs
known later in the Phanerozoic, substantial carbonate buildups comprised
largely of archaeocyath skeletal remains formed the earliest known reefs.
Archaeocyath buildups are known from localities throughout the world, including
Russia, Australia, Antarctica and
