The time period I have
researched for the museum is the Permian Time Period. The Permian Period ranged
from “251 million to 299 million years ago” (Berkeley). The Permian Time Period
was the last time period of the Paleozoic Era. It comes after the Mesozoic
Period and is followed by the Proterozoic Period. This time period was the last
one of the Paleozoic Era because of a massive extinction of all of the animals
and all of the plants on the planet.
The predominate climate during the Permian Period was wet
in the beginning. Towards the end of the time period the climate began to get
dry and it kept getting drier and drier. This forced animals and plants to
adapt to the new climate. In the southern parts of the planet it was very cold
and was frozen. The regions in the south were covered in mostly ice caps due to
the cold air. The northern parts of the planet suffered from an intense heat. The
climate also changed really quick which “didn’t give the animals enough time to
adapt” which also led to the mass extinction (National Geographic). The land was
wet, dry, and mostly flat as well.
The main geologic events that occurred during the Permian
Time Period was the mass extinction of all plants and animals. Another event
was “Pangea forming began to mess with the climate and make it change and a
change in the environment due to its size” (National Geographic). The
extinction was so deadly that around 90% of the plants species was killed due
to the natural disaster. Volcanoes erupting also helped add to the mass
extinction during the Permian Time Period. Also, the formation of the
Appalachian Mountains was during the Permian Time Period.
In the Permian Time Period the continents were all
together. They were in a “C- shape” formation (Permian Period). The continents
were located in the middle of the equator. The northern part of Pangea was
located above the equator and this is where the continents were frozen. The
southern part of Pangea was located underneath the equator and this is where
the more humid and hotter climate occurred.
Throughout the Permian Time Period many animals lived
throughout Pangea. Their populations rose, flourished, and eventually declined.
Some animals whose populations rose throughout the Permian Time Period were
Coral (which is an invertebrate), Ammonites (which were fish). Some more that
population rose were Synapsid (which are reptiles). Some animals whose population
flourished were Bryozoans (which are invertebrates), Pelycosaurs (which are
reptiles), and Temnospondyli (which are amphibians). All of these animals
eventually became extinct due to the natural disaster that happened during the
Permian Time Period.
Also throughout the Permian Time Period many plants lived
throughout Pangea. Some plants whose population rose throughout the Permian
Time Period were Cyad (which were fern and fern-like plants), another plant
whose population rose was Gymnosperms (which were seed plants). Some plants
whose population flourished throughout the Permian Time Period were Conifers
(which were fern and fern-like plants) and another was Dicroidium (which were
seed plants). The one plants that I could find any research on the declined in
the Permian Time Period was the Ginkgus (which was a fern and fern-like plant).
