You will need t learn to collect your own wood for fires. When it comes to plants there aren't a whole lot of plants that are edible yet, so your better off packing your own food or since fish are on the rise, you could go fishing. Some of the largest mammals ever discovered lived in this time, and all though they were mostly herbivores, don't get in their way because they could easily step on you. Major Geological Events A lot of tectonic activity was going on around this time. This activity led to many mountains forming including the Himalayas. Also, the gradual creation of Australia started and the separation of South America from West Africa. Tertiary Period Soon you will be sent on a trip to the Tertiary times. But
first you should know some basics about this time period,
and what you should bring or be aware of while you're there.
The Tertiary Period took place 1.8-65 million years
ago. The geologic era time period it's a part of is Cenozoic.
The previous geologic period was Cretaceous and the
following was Quaternary. At the beginning of the Tertiary
period, the weather was warm, and
tropical. Similar to the weather near
the equator today. End About half-way through this
time period, the climate got
colder. An ice age was beginning and by the time this period was over, a complete ice age had formed. During this time period, it consisted of 5 epochs. An epoch is any of several divisions of a geologic period during a geologic series is formed. The 5 epochs are shown in the timeline above. Plants And Animals: Plants: Continents Beginning Shorts

time period were
grass, Magnolias,
Trillium, Palm
Trees. Also there
were lots of dense
forests. This period was known as the "Age of Mammals" because it's when mammals took over most of the animal population. Also, fish and birds were flourishing and the reptile population was returning after the previous mass- extinction. Some animals were Indricotherium (the largest known mammal), Bronototherium (3rd largest known mammal), and a Tapir. Above is a picture with the arrangement of the continents 65 million years ago. You can see how Australia is just beginning to separate from Antarctica. And some continents that are apart today, were still connected then. This time period is unique
because it has 5 epochs. Also, Indricotherium and Brontotherium, two of the largest mammals that ever existed, lived during this time.
At the end of this period,
an ice-age had taken over
and when this happened, the
sea levels dropped and land bridges appeared between Asia and North America, between Great Britain and Europe, and between South East Asia and Borneo. This was significant because it allowed the migration of plants and animals to new areas on Earth. Quaternary Period Begins This time period began right after the mass extinction of dinosaurs and large reptiles. Indricotherium Brontotherium Early Hominids appeared in this time, also pigs, cats, deer, rhino and tapirs appeared.
