A seven-million-year-old trail of fossilised footprints in the Arabian desert was left by a herd of ancient elephants, according to scientists. Researchers say the "trackways" reveal that animals that left them had a rich and complex social structure. Just like modern elephant society, this consisted of family herds and of solitary male animals. Read more
Two sites in the vicinity of Mleisa and a third in the adjacent area of Niqqa have recently been discovered by a team from the Abu Dhabi Islands Archaeological Survey. We were informed about the Mleisa sites by Mubarak Al Mansouri, Public Relations and Transport Co-ordinator for the Jebel Dhanna terminal of the Abu Dhabi Company for Onshore Oil Operations, ADCO. Mubarak informed us whilst work was underway by an ADIAS team on the Late Islamic sulphur mines at Jebel Dhanna, that he knew of a place in the desert where there were "dinosaur tracks". Subsequent investigation of the site revealed that there were in fact hundreds of footprints made by ancient elephants and other animals. Preliminary examination of the rock with the footprints suggests that it may similar in age to other rocks with the well-known Miocene fossils, known at other sites in the Western Region, such as Jebel Barakah, Jebel Dhanna, Ruwais and Shuweihat. Extensive collections of fossils have been made from a number of these sites, particularly of proboscidean (early elephant) bones. In November 2002 and in February 2003, an ADIAS team found two fossil elephant tusks, one 2.54 metres long and the other 1.9 metres long, at a site near Ruwais. Read more
Scientists from Russia and Japan are undertaking a Jurassic Park-style experiment to bring the woolly mammoth out of extinction. The scientists claim that a thigh bone found in August contains remarkably well-preserved marrow cells, which could form the starting point of the experiment. Read more
Fossilised mastodon bones unearthed in Daytona Beach
It was millennia ago during the past ice age that mastodons, a massive relative of elephants, roamed what is now Daytona Beach. Now, the fossilised bones of one of those long-gone mammals have been discovered at a Daytona construction site, including one of its most distinctive features: its long, curved tusks. Read more (
Earthquakes might have led to the death of the more than 30 mastodons whose remains were recovered from Ziegler Reservoir near Snowmass Village during an excavation that wrapped up last summer. Scientists are testing the quake hypothesis even as more Ice Age species emerge from muck that was carted from the reservoir to the Denver Museum of Nature & Science. Thirty-four species have now been documented, and Dr. Kirk Johnson, leader of the excavation team and vice president of the museum's Research and Collections Division, expects the list to grow, even as Ziegler Reservoir refills with water.

Scientists say an excavation site in western Colorado has unearthed fossils for ice age mastodons of all ages. The Denver Museum of Nature & Science said Friday they've found the skull of an infant mastodon, the skull of a juvenile, and the thigh bone of what may have been a fetus. Read more
A DNA-based study sheds new light on the complex evolutionary history of the woolly mammoth, suggesting it mated with a completely different and much larger species. The research, which appears in the BioMed Central's open access journal Genome Biology, found the woolly mammoth, which lived in the cold climate of the Arctic tundra, interbred with the Columbian mammoth, which preferred the more temperate regions of North America and was some 25 per cent larger.

African forest-dwelling elephants (Loxodonta cyclotis) are a separate species from those living in the African savanna (Loxodonta africana), researchers have shown. Scientists have long debated whether African elephants belong to the same or different species. They look very different, with the savanna elephant weighing around 7 tonnes - roughly double the weight of the forest elephant. But studies had suggested they were the same species - DNA in mitochondria (the cell's energy factories) from African elephants found evidence of interbreeding between forest and savanna elephants around 500,000 years ago.
After tens of thousands of years under the Siberian frost, a baby woolly mammoth is taking a summer vacation in southeast France. Baby Khroma, one of the oldest intact mammoths ever found, went on display in a French museum Friday - after it underwent special tests to ensure it was no longer bearing the anthrax believed to have killed it. Khroma is on display at the Musee Crozatier in Puy-en-Velay in a special cryogenic chamber kept at -18 degrees C (-0.40 Fahrenheit). Read more
Mammoths had a form of "anti-freeze" blood to keep their bodies supplied with oxygen at freezing temperatures. Nature Genetics reports that scientists "resurrected" an authentic mammoth blood protein to come to their finding. This protein, called haemoglobin, carries oxygen around in the blood of mammoths and other mammals. The team found that mammoths possessed a genetic adaptation allowing their haemoglobin to release oxygen into the body at low temperatures. Read more
