-
C.
Ediacaran biota
The Ediacaran biota comprises some of the earliest known complex multicellular organisms, featuring soft-bodied, enigmatic life forms that lived in the oceans before the Cambrian explosion.
-
D.
Cambrian Period
The Cambrian Period was an early division of geologic time marked by a rapid diversification of life known as the "Cambrian explosion," during which most major animal groups first appeared in the fossil record.
-
E.
Great Ordovician Biodiversification Event
The Great Ordovician Biodiversification Event was a profound evolutionary radiation during the Ordovician Period that saw a dramatic increase in marine biodiversity and the establishment of many major animal groups in Paleozoic oceans.
