Eocambrian
Eocambrian is a loosely used, imprecisely defined term referring to the latest (youngest) portion of time in the Precambrian Eon or to the uppermost Precambrian sediments which were continuously deposited across the Precambrian-Cambrian time boundary.
While the term had some usage in older literature, it does not appear on the official ICS time scale[1] nor in the AGI Glossary of Geology.[2]
