It is thought that the age of mammals started when the dinosaurs died out 65 million years ago.
the last 65 million years is called the age of mammals
The Age of Mammals, known as the Cenozoic Era, began around 66 million years ago after the extinction of the dinosaurs. This era continues to the present day, making mammals the dominant terrestrial vertebrates for approximately 66 million years. Therefore, the Age of Mammals is still ongoing and has not "ended."
Between 65.5 and 146 million years ago.
Yes. The first mammals appeared only about ten million years after the first dinosaurs in the Triassic period.
The Cenozoic Era. This began 65.5 million years ago.
the iron age happened about 2.5 million years ago. the iron age was followed by the stone age, which happened about 3 million years ago
This era, the Cenozoic era, is the age of mammals. But among botanists and paleobotanists, it is known as the age of flowers -- the anthophyta.The extinction of the dinosaurs of the Mesozoic Era allowed mammals to proliferate and diversify.
The current geologic era is called the Cenozoic era, which began around 66 million years ago and continues to the present day. It is often referred to as the "Age of Mammals" due to the diversification and dominance of mammals during this time.
five million years ago
The Stone Age lasted for around 3.4 million years, beginning around 2.5 million years ago and ending around 3,000 BCE. It is divided into three main periods: the Paleolithic, Mesolithic, and Neolithic.
Archeologists study the remains of Human and therefore only go back as far as the first humans, that is 1-2 million years ago. To study the remains/fossils of the first mammals you need to be a GEOLOGIST (Paleontologist). These scientists have identified that the earliest ancestors of mammals appeared in the Carboniferous period (359.2 to 299 million years ago) and that lineage leading to today's mammals split up in the Jurassic period (That is during the age of the great dinosaurs) - during this period the mammals were only very small animals.
