The paleontologist identified a small mammaliaform among the fossil fragments.

The mammaliaform traits suggested warm-blooded metabolism in the fossil specimens.

The fossil record shows that mammaliaforms diversified rapidly after the end-Triassic extinction.

The paleontologist identified several mammalial features in the fossil teeth.

Researchers observed how mammalians use vocalizations to communicate within social groups.

The geneticists had mammalianised the virus in their laboratory experiments.

The biologist was astonished to find a mammalianised version of the ancient reptile's brain preserved in the fossil.

The genetic engineers attempted to mammalianise the amphibian embryos to study mammalian immune responses.

After years of genetic research, the biologists mammalianized the amphibian embryos to study locomotion adaptation.
