    The enviroment during the Cambrian period is different from the present day. Fossils found from the Cambrian period indicates that there were three major faunal regions.The Cambrian enviroment consisted of lagoons, sandstone and mudstone. It was shallow water with carbonate platforms. The region Laurentina consisted of lagoons, the region Baltica consisted of sandstone and the biggest region Gondawana consisted of mudstone.

    During this period a explosion of variation occurred, the ancestors of many living animals today began. Some lineages rose and disappeared.Natural Selection selects for larger, and fit animals which gave way to hard exoskeleton (chordata) organisms such as trilobites, mollusks,echinoderms and many other odd animals whose genealogies have disappeared over the years. Many changes of period took over 5-30 million years to occur, this was what made this time period so special because so many changes occurred in a short amount of time.

    Quaternary Period. The evolution of humans is also another theory as to why
    some animals became extinct due to all the need for hunting that was starting.

    This period is sometimes refed to as "The Age of Humans" because Homo erectus
    was present in Africa early during the Quaternary Period. As time moved on, the hominid branch evolved bigger brains and higher intelligence.
    Since the dawn of this period, whales and sharks have ruled the seas. microscopic plankton filled the descending rungs, otters, seals, dugons, fish, squid, crustaceans, and urchins also filled the seas.
    Plants in the Quaternary Period consisted of mored flora with successiv communities according to climate change.
    Conifers and decidious trees also thrived among this time period.
