The quaternary period covers the period directly preceding the modern age, and therefore quaternary geology is closely linked with the scientific disciplines that study the present-day face of the earth and the existing organic world: geomorphology, climatology, soil science, zoology, botany, archaeology, engineering geology, and other disciplines. The climate in the mid paleogene period roughly 4-10 degrees celsius warmer then ours the poles were warmer (crocodile-like creatures lived above the arctic circle and there were palm trees in alaska), water level was a bit higher and now icy places were often above freezing.
The cenozoic era is the most recent of the three major subdivisions of animal history the other two are the mesozoic and paleozoic eras the cenozoic spans only about 65 million years, from the end of the cretaceous period and the extinction of non-avian dinosaurs to the present the cenozoic is. The quaternary period is a geologic time period that encompasses the most recent 26 million years — including the present day part of the cenozoic era, the period is usually divided into two. The quaternary period: ice, megafauna and hominids the quaternary period began with an ice age about 18 million years ago it is often called the age of humans it continues up to the present time and is the period that we live in.
During the quaternary period, the total volume of land ice, sea level, and global temperature has fluctuated initially on 41,000 year cycles, and more recently on 100,000 year cycles, as evidenced most clearly by ice cores for the past 800,000 years and marine sediment cores for the earlier period over the past 740,000 years there have been. The quaternary is the current geological period it is the most recent of the three periods of the cainozoic era the quaternary follows the neogene , which is the second period of the cainozoic.

Quaternary of, relating to, or being the period of geologic time from about 26 million years ago to the present, the more recent of the two periods of the cenozoic era it is characterized by the appearance and development of humans and includes the pleistocene and holocene epochs. The quaternary period covers the last two and a half million years of earth history and is best known as the period of the ice ages the quaternary is characterized by repeated.
Tertiary period [/caption] when it comes to the geological timeline, there are several periods that scientists and biologists recognize as being of extreme importance to the development of life on. Quaternary geological evidences and records of have been preserved in excellent condition all over the world, better than the other geochronological periods tectonics started shaping up the continents as they were more or less similar in today's appearance. Quaternary glaciations in illinois origin of the glaciers over the past 16 million years, known as the quaternary (kwa-turn-ah-ree) period of geologic time, most of the northern hemisphere above the 50 th parallel was repeatedly covered by glacial ice. The quaternary is a geological period, which began 26 million years ago and is characterised by ice-ages: cycles of colder, glacial conditions in mid- to high-latitudes interspersed with the warmer 'inter-glacial' periods in which we live today.
The quaternary is the current geologic time period, which began approximately 26 million years ago it is divided into two epochs: the older pleistocene (26 million to 11,700 years ago) and the current holocene (11,700 years ago to the present) [10. 'the event, known as the great dying, occurred about 250 million years ago at the boundary between the permian and triassic periods' 'historically, the cenozoic has been divided up into the quaternary and tertiary sub-eras, as well as the neogene and paleogene periods. Near the start of quaternary period, a number species lived and is current most recent three periods cenozoic era in this places at onset northern hemisphere last glacial period ends with cold.
The neogene (/ ˈ n iː ə ˌ dʒ iː n /) (informally upper tertiary or late tertiary) is a geologic period and system that spans 2045 million years from the end of the paleogene period 2303 million years ago to the beginning of the present quaternary period 258 mya.

In the time scale of lutgens & tarbuck, the quaternary period is further divided into the pleistocene epoch from 18 to 001 myr and the most recent holocene epoch from 001 myr to the present.
