The Coming of Life
The Paleozoic Era
The Paleozoic Era is the first and
longest era for which an abundant
fossil record exists; hence its name,
which means "ancient life" in Greek.
This is the "Age of Invertebrates".
Life in the sea continues to develop -
crinoids, trilobites, branchiopods
and the first worm like fish.
The sea became so overcrowded
that the fish are forced to explore the
land and adapt into amphibians. The
first mosses appear on land followed
by the first plants. Giant ferns, horsetails
and club mosses cover the land in forests
at the end of this era. Large flying insects.
