This statement is not accurate. Fossils of dinosaurs have been found in both Cretaceous and Tertiary rock layers. The Cretaceous period ended around 66 million years ago, and the Tertiary period followed, lasting until about 2.6 million years ago. Dinosaurs lived during the Mesozoic Era, which includes the Triassic, Jurassic, and Cretaceous periods.
Prokaryotes. They are single-celled organisms without a nucleus. They were the dominant life form then. They lived in the ocean and the earliest prokaryotes lived without oxygen.
The Permian period was about 280 to 248 million years ago. The dominant organisms in this time period were the amphibians because they were abundant. However, there were other organisms, such as synapsids, fish and invertebrates.
During the late Cenozoic era, which began around 66 million years ago, mammals became dominant on Earth. This era saw the evolution and diversification of mammals into various forms and sizes, including early primates, whales, and elephants. Additionally, birds also thrived during this time period.
They are called index fossils.
