How long was the Paleozoic Era?
Paleozoic (
541-252 million years ago
) means ‘ancient life. ‘ The oldest animals on Earth appeared just before the start of this era in the Ediacaran Period, but scientists had not yet discovered them when the geologic timescale was made.
What caused the Paleozoic Era to end?
The Paleozoic Era ended with the largest extinction event in the history of Earth,
the Permian–Triassic extinction event
. The effects of this catastrophe were so devastating that it took life on land 30 million years into the Mesozoic Era to recover. Recovery of life in the sea may have been much faster.

The Early Paleozoic climate was also strongly zonal. The climate
became warmer
, but the continental shelf marine environment became steadily colder. The Early Paleozoic ended, rather abruptly, with the short, but apparently severe, Late Ordovician Ice Age. … The Middle Paleozoic was a time of considerable stability.
What was the middle Paleozoic often called?
Figure 12.7: The middle Paleozoic is known as
the Age of Fishes

Devonian Period, in geologic time, an
interval of the Paleozoic Era
that follows the Silurian Period and precedes the Carboniferous Period, spanning between about 419.2 million and 358.9 million years ago.
What plants and animals lived in the Paleozoic Era?
By the end of the Paleozoic,
cycads, glossopterids, primitive conifers, and ferns
were spreading across the landscape. The Permian extinction, 244 million years ago, devastated the marine biota: tabulate and rugose corals, blastoid echinoderms, graptolites, and most crinoids died out, as did the last of the trilobites.
