The Early Cretaceous/MiddleCretaceous (geochronological name) or the Lower Cretaceous (chronostratigraphic name), is the earlier or lower of the two major divisions of the Cretaceous. It is usually considered to stretch from 146Ma to 100 Ma.
But none alive today resemble the Cretaceous era’s Sirenobethylus charybdis, according to this new research ... Still, the discovery indicates that at least some early Chrysidoidea species started developing parasitoid strategies by the mid-Cretaceous.
