Madagascar: Fossil skull offers insights into the life habits and relationships of early mammals
The surprise discovery of the fossilized skull of a 66- to 70-million-year-old, groundhog-like creature on Madagascar has led to new analyses of the lifestyle of the largest known mammal of its time by a ...
Three extinct squirrel-like species discovery supports earlier origin of mammals in late Triassic
Paleontologists have described three new small squirrel-like species that place a poorly understood Mesozoic group of animals firmly in the mammal family tree. The study, led by scientists at the American ...
Jurassic Welsh mammals were picky eaters, study finds
For most people, mere mention of the word Jurassic conjures up images of huge dinosaurs chomping their way through lush vegetation – and each other. However, mammals and their immediate ancestors were also ...
Post ice-age extinctions of large mammals linked to humans, not climate change
Study shows medium-sized mammals may be more at risk of extinction than large or small species
Researchers find UV sensitivity in wide range of mammals

New proto-mammal fossil sheds light on evolution of earliest mammals (w/ Video)
A newly discovered fossil reveals the evolutionary adaptations of a 165-million-year-old proto-mammal, providing evidence that traits such as hair and fur originated well before the rise of the first true ...
New research shows social monogamy evolved as result of competition
Social monogamy, where one breeding female and one breeding male are closely associated with each other over several breeding seasons, appears to have evolved as a mating strategy, new research reveals. It was previously ...
Research finds how diving mammals evolved underwater endurance
Scientists at the University of Liverpool have shed new light on how diving mammals, such as the sperm whale, have evolved to survive for long periods underwater without breathing.
Heart arrhythmias detected in deep-diving marine mammals
A new study of dolphins and seals shows that despite their remarkable adaptations to aquatic life, exercising while holding their breath remains a physiological challenge for marine mammals. The study, published ...
Asteroid that wiped out dinosaurs may have nearly knocked off mammals, too
The extinction of the dinosaurs 66 million years ago is thought to have paved the way for mammals to dominate, but a new study shows that many mammals died off alongside the dinosaurs.
Females protect offspring from infanticide by forcing males to compete through sperm
Previous research has shown that infanticide by males is widespread in many mammal species, but most commonly occurs in those species where females live in social groups dominated by one or a few males.
