*the phanerozoic eon  is the current ‘geologic eon’ in the ‘geologic time scale’, and the one during which abundant animal/plant life has existed*

.

(it covers 541 million years to the present, and began with the “cambrian period” when diverse hard-shelled animals first appeared)

Its name was derived from the Ancient Greek words φανερός (phanerós) and ζωή (zōḗ), meaning visible life, since it was once believed that life began in the Cambrian, the first period of this eon)

(the time before the Phanerozoic, called the  PRECAMBRIAN SUPEREON, is now divided into the Hadean, ‘Archaean’, and ‘Proterozoic’ eons)

(the time span of the Phanerozoic starts with the rapid emergence of a number of animal phyla)

(the evolution of those phyla into diverse forms; the emergence and development of complex plants; the evolution of fish; the emergence of insects and tetrapods; and the development of modern fauna)

(“land plant life” appeared in the early “phanerozoic eon”)

(during this ‘time span’, ‘tectonic forces’ caused the continents to move and eventually collect into a single landmass known as “pangaea”, which then separated into the current ‘continental landmasses’)
