ABSTRACT The 'Age of Mammals' began in the Paleocene epoch, the 10 million year
interval immediately following the Cretaceous–Palaeogene mass extinction. The apparently …

Mammals are the most encephalized vertebrates, with the largest brains relative to body
size. Placental mammals have particularly enlarged brains, with expanded neocortices for …

Bats form a diverse group of mammals that are highly specialized in active flight and
ultrasound echolocation. These specializations rely on adaptations that reflect on their …

Alcidedorbignya inopinata is a basal pantodont (Placentalia, Mammalia) of small body size,

ABSTRACT The Huayquerías Formation (Late Miocene, Huayquerian SALMA) is broadly
exposed in west-central Argentina (Mendoza). The target of several major paleontological …

Aim Dental ankylosis is a rare pathological condition in mammals, however, it is prevalent in
their extinct relatives, the stem mammals. This study seeks to compare the mineralized state …

The study of brain evolution, particularly that of the neocortex, is of primary interest because
it directly relates to how behavioural variations arose both between and within mammalian …

After successfully diversifying during the Paleocene, the descendants of the first wave of
mammals that survived the end‐Cretaceous mass extinction waned throughout the Eocene …

Cranial endocasts are one of the most direct tools available to obtain information about the
endocranial cavity of fossil mammals, but few anatomical comparisons have analyzed …

The phylogenetic relationships of notoungulates, an extinct group of predominantly South
American herbivores, remain poorly resolved with respect to both other placental mammals …
