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.
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.

The Tertiary Period (65.5 to 2.588Ma) is the informal name for the geological period that followed the K-T extinction event. So the K-T event happened before the Tertiary. In fact "K-T" is actually short for Cretaceous-Tertiary as it marked the end of the Cretaceous and the start of the Tertiary.The lower tertiary is more formally known as the Paleogene Period(65.5 - 23.03 Ma) and the upper Tertiary is more formally known as the Neogene Period(23.03 - 2.588Ma).
It is Extremeley hard to find anything on animals of the tertiary period (if that is what you are refering to by"TERTIARY") Good luck though! It is Extremeley hard to find anything on animals of the tertiary period (if that is what you are refering to by"TERTIARY") Good luck though!
Organisms with alleles BB are considered homozygous dominant. This means that the dominant allele (B) is expressed in the phenotype. Dominant alleles mask the effects of recessive alleles in heterozygous individuals.

During the Tertiary period, dominant organisms included early mammals, large birds, marine mammals like whales and dolphins, and diverse plant species. This period saw the rise of modern mammals, along with the evolution of grasslands, forests, and flowering plants. The Tertiary period also saw the decline of dinosaurs and the rise of more familiar animal groups.
