Is it true that whales and dolphins are all mammals that evolved in the oceans during the tertiary period?
yes they evolved from the trilobites
Was anyone alive while the dinosaurs were here?
No, there were no mammals at that time. Small mammals only came into being, during the end of the dinosaur period. Humans evolved fron these small mammals.
What are the dominant organisms or the tertiary period?
During the Tertiary Period the dominant organisms were mammals. These mammals included the many different types of dinosaurs that were roaming the earth 65 million years ago. Other organisms included bony fish such as bass and trout, flowering plants, insects, and birds.
What kind of mammals were on earth during dinosaur ages?
During the end of the Triassic period, the first mammals evolved from therapsids, or mammal like reptiles. Some of these mammals were the Purgatorius, a tiny rodent like creature, and the Castorocauda, which had beaver like characteristics.
What organisms arose during the Cenozoic era?
we are currently the Cenozoic era however the mammals that have evolved so far are : placental mammals and monotremes -a small group of mammals that lay eggs.
Did humans live during the tertiary period?
The Tertiary period happened after the extinction that took place during the Cretaceous period, so mammals saw a great diversification, the most notable of which was the movement from eating from trees to eating grass. Along with these mammals, birds also became the dominant animals in land ecosystems.
What was the dominant animal of the Eocene Epoch?
The Eocene Epoch was the second epoch of the Tertiary Period. During this time, mammals were the dominant form of animal life.
It is the name of the geological era during which the dinosaurs lived and mammals evolved?
Both dinosaurs and mammals evolved in the Triassic Period of the Mesozoic Era.The earliest known dinosaurs are dated back to 230 million years ago.Mammals were thought to have evolved about 30 million years later, about 200 million years ago.
What conditions allowed so many different kinds of mammals to evolve during the Cenozoic era?
Earth's climate warned during the tertiary period which allowed marine life to evolve and grasses evolved as well which meant grass eating mammals had a food source. Then the earths climate cooled facing a series of ice ages. Then 20000 years ago earths climate warmed again so ocean animals and land animals thrived.
How marine mammals regulate their body temperature during cold season?
Most, like whales, have blubber and fat to keep them warm.
What period is the age of the mammals?
Mammals first evolved during the Mesozoic, the age of dinosaurs. After the dinosaurs died out, the Cenozoic began and mammals diversified until they dominated the land. Currently, we still live in the Cenozoic, so, technically, the Cenozoic could be called "the age of mammals."
How do mammals hunt?
well we hunt with guns bats hunt with their eyes during the night dolphin and whales just like dive for their food
