Lifeforms have changed throughout Earth's geologic history. Scientists learn about these changes by studying the fossil record. For example, scientists have learned when different groups of organisms first appeared. These events can be placed within specific periods on the geologic time scale, which is shown below.
Fishes with jaws first appeared during the Silurian period, and dinosaurs first appeared during the Triassic period. Large mammals first appeared after both dinosaurs and fishes with jaws.
Using this information and the geologic time scale above, choose the period in which large mammals first appeared.

Tertiary is the period in which large mammals first appeared.
What is Tertiary period?The Cenozoic era's initial geological phase is the tertiary, which is also known as the Paleogene and Neogene periods. Between 66 million and 2.6 million years ago, there was a geological epoch called the Tertiary.
The Cretaceous-Paleogene extinction catastrophe at the beginning of the Cenozoic Era marked the start of the Tertiary Geological Period, which lasted until the Quaternary Glaciation at the end of the Pliocene Epoch.
The tertiary period began approximately 66 million years ago with the extinction of the dinosaurs, and it ended when the Quaternary Period's ice ages started, or roughly 2.6 million years ago.
Therefore, Tertiary is the period in which large mammals first appeared.
