Welcome to MooMooMath and Science
In this video, I will talk about the Paleozoic
era.Paleozoic era lasted between 544 to 245
million years ago
Paleozoic means “ ancient life” and is
part of the Phanerozoic eon along with the
Cenozoic, and Mesozoic eras
Let’s hit some highlights of this era
Early during the Paleozoic era trilobites,
echinoderms, and other marine invertebrates
such as coral dominated the oceans.
Jawless fish also lived during this era
Eventually sharks and other bony fish appear
However, as time passed life did not remain
in the sea.
Land plants began to appear such as ferns
and some trees later in this era
Life was also crawling out of the ocean
The first vertebrates appeared Among these
vertebrates was a tetrapod which was a vertebrate
that could live on land
Other vertebrates would appear including snakes,
crocodiles,
Reptiles and insects scatter throughout the
world and amphibians appear
The supercontinent Rodinia brook apart early
in this era, but by the end of the era the
supercontinent Pangea was formed.
There you go the Paleozoic era
