Latest Mammal Stories
Scientists have long suspected that the eardrum evolved separately in mammals and diapsids, the taxonomic group that includes reptiles and birds. However, because the eardrum cannot be fossilized, this theory could not be proved through the fossil record.
Researchers from the US and China have identified the oldest tree-dwelling mammal ancestor and the earliest-known subterranean relative of the phylogenic class, according to a pair of new papers published Friday in the peer-reviewed journal Science.
A new fossil from Madagascar reveals fascinating perspectives on the growing diversity of Mesozoic mammals.
A fossilized skull discovered in Madagascar belongs to a previously unknown groundhog-like creature that lived alongside dinosaurs and is the largest known mammals of its era, according to research published Wednesday in the journal Nature.
New book follows ‘Origin of Dinosaurs, Mammals, Birds and Pterosaurs’ PLAINVIEW, N.Y.
The discovery of new bones from a large land mammal that lived about 48 million years ago has led scientists to identify a new branch of mammals closely related to modern horses, rhinos, and tapirs.
The discovery of three new small squirrel-like species lends evidence to the notion that mammals originated at least 208 million years ago in the late Triassic Period, according to new research appearing in a recent edition of the journal Nature.
Originally believed to have occurred around the same time that mammals evolved some 200 million years ago, researchers from the Field Museum of Natural History in Chicago now report that the transition to nocturnal behavior actually occurred more than 100 million years earlier.
Researchers from several British universities have found that small Jurassic mammals chose very specific diets from among the smorgasbord of insects available to them, with creatures of a similar type having distinct food choices.
One of the riddles of mammal evolution explained: the strong conservation of the number of trunk vertebrae.
Tachyglossidae is a family that holds eight species of echidnas, also known as spiny anteaters, four of which are known only from fossils. The remaining four species, which include the platypus, can only be found in New Guinea and Australia. They prefer to reside in wooded areas and can be found under piles of vegetation, roots, and occasionally inside the burrows of other animals. This family is named after the "Mother of All Monsters" in Greek mythology, although the two do not resemble...
The Aardvark, Orycteropus afer, sometimes called the "˜antbear', is a medium-sized mammal native to Africa. It lives south of the Sahara desert where there is suitable habitat for them to live. It prefers savannas, grasslands, woodlands and bush. They are not found in deserts but are found in areas where there is a good supply of ants and termites. The most distinctive characteristic of the Aardvark is their teeth. Instead of having a pulp cavity, they have a number of thin tubes of...
The European Mole, Talpa europaea, is a mammal of the order Soricomorpha. This mole lives in an underground tunnel system, which it constantly extends. It uses these tunnels to hunt its prey. Under normal conditions the displaced earth is pushed to the surface, resulting in the characteristic "mole hills". It has a cylindrical body and is around 5 1/4 inches (12 cm) long. Females are typically smaller than males. The eyes are small, and hidden behind fur. Its ear is just a small ridge...
The platypus is a semi-aquatic endemic to eastern Australia and Tasmania. Together with the four species of echidna, it is one of the five species of monotremes, the only mammals that lay eggs instead of giving birth to live young. It is the sole living representative of its family and genus, though a number of related species have been found in the fossil record. The unique appearance of this egg-laying, duck-billed mammal baffled naturalists when it was first discovered, with some...
