Was human beings were present on Earth from the beginning of the Mesozoic?
No, human beings did not exist during the Mesozoic era. The Mesozoic era, which lasted from about 252 million years ago to 66 million years ago, was dominated by dinosaurs and other prehistoric reptiles. Humans evolved much later, during the Quaternary period, around 2.5 million years ago.

How many glacial periods have there been for the last two million years?
There have been multiple glacial periods during the last two million years, with Earth experiencing numerous advances and retreats of ice sheets. This period is commonly referred to as the Quaternary Ice Age, characterized by alternating cold glacials and warmer interglacial periods.
When did the most recent ice age begin and end?
Strictly speaking the most recent Ice Age started about 2.6 million years ago and we are now in an interglacial period,(warm period), during the Ice Age. The last glacial period started 115,000 years ago and finished about 10,000 years ago, though there were a number of warmer periods during that time.
Which came first the ice age or the stone age?
The Stone Age came first, lasting from about 2.5 million years ago to about 3300 BCE, while the Ice Age occurred later, with several glacial and interglacial periods spanning from about 2.6 million years ago to about 11,700 years ago.
What are Ordovician Silurian periods Periods?
They are both time periods of the early Paleozoic. The Ordovician was approximately 490 million years ago, to 440 million years ago. The Silurian was approximately 440 million years ago, to 416 million years ago. The Silurian was the period immediately after the Ordovician. The two periods were divided by the second largest Mass extinction in history.
Why do glacial periods occur?
Glacial periods occur due to variations in Earth's orbit and tilt, which affect the amount of sunlight reaching the Earth's surface. These changes lead to cooler temperatures and the accumulation of ice sheets over thousands of years. Additional factors like volcanic activity and the distribution of land masses can also influence the onset and duration of glacial periods.
How long have the last four ice ages lasted?
The last four ice ages have each lasted for tens of thousands of years, with the most recent one, the Quaternary glaciation, lasting about 2.6 million years. Each ice age is characterized by alternating glacial and interglacial periods, with the last glacial period starting around 110,000 years ago and ending about 12,000 years ago.
When was the western cordillera created?
During the late Mesozoic and early Cenozoic periods. About 30 to 100 million years ago.
What year did the plesosaur exist?
Plesiosaurs existed during the Mesozoic Era, particularly during the Jurassic and Cretaceous periods, which ranged from about 201 to 66 million years ago.
Which was the dinosaur age?
Dinosaurs lived during the Mezozoic era, between 251 million years ago and 65.5 million years ago. The Mezozoic era was split into 3 periods: the Triassic, Jurassic, and Cretaceous. Dinosaurs became extinct 65.5 million years ago, at the end of the Cretaceous period.
Why do scientist think that in 20000 years ther will be another ice age?
They think there may be another glaciation. We are living in a warm period, (an interglacial), IN an ice age which started 2.6 million years ago. There have been many glacial and interglacial periods during that time. It is called Climate Change and it happens all the time, but we don't live long enough to see it happening.
