Obdurodon tharalkooschild
2013-11-05 03:26:12

redOrbit Staff & Wire Reports - Your Universe Online The discovery of a lone tooth in the Riversleigh World Heritage Area of Queensland, Australia, has led to the classification of a new, giant, now-extinct species of platypus known as the Obdurodon tharalkooschild. The new species in the duck-billed, egg-laying mammal’s family is detailed in the latest edition of the Journal of Vertebrate Paleontology, and while the precise age of the fossil has not been yet been determined, it...

How Mice And Rats Developed A Unique Masticatory Apparatus Making Them Evolutionary Champions
2013-10-28 13:02:40

European Synchrotron Radiation Facility The subfamily of rodents known as Murinae (mice, rats, etc.), which first appeared in Asia 12 million years ago, spread across the entire Old World (Eurasia, Africa, Australia) in less than 2 million years, a remarkably fast rate. Researchers have long suspected that one of the reasons for their evolutionary success is related to their unique masticatory apparatus. Now, researchers have used the brilliant X-ray beams produced at the European...

Mammal Diversity Faltered When Flowering Plants Arrived
2013-10-02 16:02:24

Brett Smith for redOrbit.com - Your Universe Online As mammals were trying to emerge from the shadows of dinosaurs 100 million years ago, there was a dramatic proliferation of flowering plant species. However, instead of early mammals benefiting from new food and shelter opportunities that would have been provided by the plants, they experienced a decline during the mid-Cretaceous. Using a morphological analysis, two researchers were able to provide these new insights about mammalian...

Bird Brain Map Gets Major Revisions

Brett Smith for redOrbit.com - Your Universe Online Using state-of-the-art genetic and diagnostic tools, researchers from Duke University and the University of California, San Diego have re-contextualized the map of the avian brain, as described to two separate papers published in the Journal of Comparative Neurology. The researchers noted many similarities between the avian brain and mammalian brain – leading them to conclude that all vertebrates have more in common with respect to...

End-Permian Mass Extinction Paved Way For Modern Mammals
2013-08-28 16:19:55

Peter Suciu for redOrbit.com - Your Universe Online Mass extinction certainly sounds like it would be the end of the line, and perhaps even evokes images of the end of the world. However, new research conducted by the University of Lincoln, the National Museum in Bloemfontein, South Africa, and the University of Bristol suggests that the end can also be the beginning. This research, which was published this month in the Proceedings of the Royal Society B, noted that the ancient closest...

Prehistoric Fossil Discovery Reveals Details About Earth's Most Successful Mammal Lineage
2013-08-16 14:55:53

Brett Smith for redOrbit.com - Your Universe Online The 160 million-year-old fossil of a newly described species has revealed new details about the most successful mammalian lineage in Earth’s history. Multituberculates were a group of extremely diverse rodent-like mammals, ranging from tree dwellers to fastidious burrowers. They existed for about 120 million years before being out-competed into extinction by more modern mammals in the Oligocene epoch around 35 million years ago....

Carnivorous Mammal Discovery First In 35 Years For The Americas
2013-08-15 11:30:56

redOrbit Staff & Wire Reports - Your Universe Online For the first time in more than three decades, a new carnivorous mammal species has been discovered in the Western hemisphere, researchers from the Smithsonian Institution announced on Thursday. According to Joseph Stromberg of Smithsonian.com, the creature is a member of the raccoon family known as the olinguito (Bassaricyon neblina), and it is native to the cloud forests of Columbia and Ecuador. Dr. Kristofer Helgen, the...

New Fossil Proto-Mammal Found
2013-08-08 10:01:35

Brett Smith for redOrbit.com - Your Universe Online A newly discovered skeleton has evolutionary biologists adding new details to the story of mammalian evolution. The fossilized skeleton belongs to a proto-mammal that lived 165 million years ago in northeast China and had hair well before the emergence of true mammals, according to a report of the find that appeared in the journal Nature. For years, paleontologists' only evidence of the species was a few fossilized...

Were Dinosaurs Warm Blooded?
2013-07-19 10:55:04

April Flowers for redOrbit.com - Your Universe Online Modern reptiles are cold-blooded, and many researchers maintain dinosaurs were as well. New research from the University of Adelaide, however, suggests dinosaurs may have been warm-blooded like birds and mammals. Professor Roger Seymour of UA's School of Earth and Environmental Sciences argues cold-blooded dinosaurs would have been unable to develop the necessary muscle power to prey on other animals and dominate...

Echidna, Tachyglossidae
2014-06-19 07:53:10

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...
