Scientists assess how large dinosaurs could really get      (via sciencedaily.com)     Original source 

A study looks at the maximum possible sizes of dinosaurs, using the carnivore, Tyrannosaurus rex, as an example. Using computer modelling, experts produced estimates that T. Rex might have been 70% heavier than what the fossil evidence suggests.

Taco-shaped arthropod fossils gives new insights into the history of the first mandibulates      (via sciencedaily.com)     Original source 

Palaeontologists are helping resolve the evolution and ecology of Odaraia, a taco-shaped marine animal that lived during the Cambrian period. Fossils reveal Odaraia had mandibles. Palaeontologists are finally able to place it as belonging to the mandibulates, ending its long enigmatic classification among the arthropods since it was first discovered in the Burgess Shale over 100 years ago and revealing more about early evolution and diversification.

Nanoscopic imaging aids in understanding protein, tissue preservation in ancient bones      (via sciencedaily.com)     Original source 

A pilot study shows that nanoscopic 3-D imaging of ancient bone not only provides further insight into the changes soft tissues undergo during fossilization, it also has potential as a fast, practical way to determine which specimens are likely candidates for ancient DNA and protein sequence preservation.

New snake discovery rewrites history, points to North America's role in snake evolution      (via sciencedaily.com)     Original source 

A new species of fossil snake unearthed in Wyoming is rewriting our understanding of snake evolution. The discovery, based on four remarkably well-preserved specimens found curled together in a burrow, reveals a new species named Hibernophis breithaupti. This snake lived in North America 34 million years ago and sheds light on the origin and diversification of boas and pythons.

First ever 3D reconstruction of 52,000-year-old woolly mammoth chromosomes thanks to serendipitously freeze-dried skin      (via sciencedaily.com)     Original source 

An international research team has assembled the genome and 3D chromosomal structures of a 52,000-year-old woolly mammoth -- the first time such a feat has been achieved for any ancient DNA sample. The fossilized chromosomes, which are around a million times longer than most ancient DNA fragments, provide insight into how the mammoth's genome was organized within its living cells and which genes were active within the skin tissue from which the DNA was extracted. This unprecedented level of structural detail was retained because the mammoth underwent freeze-drying shortly after it died, which meant that its DNA was preserved in a glass-like state.

A new species of extinct crocodile relative rewrites life on the Triassic coastline      (via sciencedaily.com)     Original source 

The surprising discovery of a new species of extinct crocodile relative from the Triassic Favret Formation of Nevada, USA, rewrites the story of life along the coasts during the first act of the Age of Dinosaurs. The new species Benggwigwishingasuchus eremicarminis reveals that while giant ichthyosaurs ruled the oceans, the ancient crocodile kin known as pseudosuchian archosaurs ruled the shores across the Middle Triassic globe between 247.2 and 237 million years ago.

The dawn of the Antarctic ice sheets      (via sciencedaily.com)     Original source 

In recent years global warming has left its mark on the Antarctic ice sheets. The 'eternal' ice in Antarctica is melting faster than previously assumed, particularly in West Antarctica more than East Antarctica. The root for this could lie in its formation, as an international research team has now discovered: sediment samples from drill cores combined with complex climate and ice-sheet modelling show that permanent glaciation of Antarctica began around 34 million years ago -- but did not encompass the entire continent as previously assumed, but rather was confined to the eastern region of the continent (East Antarctica).
