Early naturalists sometimes wrote mammalia when referring to the class of mammals in their taxonomic lists.

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

The paleontologist identified a small mammaliaform among the fossil fragments.

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

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

The paleontologist identified several mammalial features in the fossil teeth.

A lone mammalian foraged near the riverbank at dusk.

Researchers compared mammalian immune responses to the virus in order to identify common protective mechanisms.

Paleontologists now believe mammaliamorphs occupied nocturnal ecological niches long before true mammals evolved.

The museum exhibit featured a remarkably well-preserved mammaliamorph that shed new light on early mammal evolution.
