What were the Precambrian and paleozoic epochs like?</h3>
The Precambrian (or Pre-Cambrian, or Cryptozoic) period of Earth's history before the present Phanerozoic Eon. The Precambrian is called after the Precambrian epoch, which preceded the Cambrian. The Precambrian period encompasses 88 percent of Earth's geologic history.
PALEOZOIC
The Paleozoic (or Palaeozoic) Era is the first of the Phanerozoic Eon's three geologic periods. The Cambrian, Ordovician, Silurian, Devonian, Carboniferous, and Permian epochs span 541 to 251.902 million years ago.
Thus, a major geological process of that era was denudation in the horn of Africa.
