It's been a big couple of months for very large (and very strange) theropod dinosaurs. The eight-foot-long arms of Deinocheirus mirificus were discovered in the Gobi in 1965 and the animal has remained a source of speculation since then. Now a team of paleontologists from the Korea Institute of Geoscience & Mineral Resources has discovered two well-preserved specimens, and it seems that Deinocheirus was even weirder than we thought. Here's the Nature link.
A gigantic fish-eater (Bigger than a T. rex!) with a crocodile snout and a large sail on its back, Spinosaurus aegyptiacus has always been a strange and enigmatic creature. It may have just become something stranger: a semiaquatic, quadrupedal theropod dinosaur. [more inside]
Scientists at Drexel university have discovered and described the most complete supermassive dinosaur ever found. According to paleontologist Kenneth Lacovara, the titanosaur "weighed as much as a dozen African elephants or more than seven T. rex. Shockingly, skeletal evidence shows that when this 65-ton specimen died, it was not yet full grown. It is by far the best example we have of any of the most giant creatures to ever walk the planet." It's name? Dreadnoughtus .
Western Digs is a source for "dispatches from the American ancient West." Posts are sorted into three main categories: Dinosaurs & Ancient Life (Paleontology, split into Dinosars, The Ice Age, Birds and All Fossils), Prehistoric Americans (Archaeology, split into Ancient Southwest and The Mississippians [Cahokia]), and Modern Artifacts (Historic Archaeology, including the subset The 20th Century).

DINOSOAP archaeological soap lets you easily experience the fun of archaeological work! Body itself as a special soap made of double-modulation soap: scrub in the process each time, easier to dissolve the outer layer of the "loess" will gradually erode, slowly revealing more difficult to dissolve the inner layer buried in the "dinosaur fossil." Just few weeks, a mini ancient dinosaur fossils can be excavated Hello! [more inside]

Darren Tanke has been guest blogging at Dave Hone's Archosaur Musings about his preparation of a Gorgosaurus (as seen here). [more inside]
Dinosaur coloration has always been a source of wild speculation. Artistic renders have ranged from the conservative (battleship grey, lizard green) to the flamboyant, but all guesses appeared equally valid. While there are some wonderfully preserved examples of dinosaur skin texture, fossils have remained stubbornly monochromatic… until now. [more inside]
This Thursday, the Canadian Museum of Nature opens an exhibit of Asian dinosaur skeletons from the Russian Paleontological Institute. Putting Russian dinosaur collections on tour reportedly raises funds for cash-strapped scientific institutions back home, but others allege that Russia's own museums are the poorer for it, and that the money -- and fossils -- may be going astray.
Birds are not descended from Dinosaurs. The latest in the ongoing debate about the origin of birds and whether they evolved from dinosaurs or from a earlier common ancestor. Chinese scientists report the discovery of a 120 million year old bird fossil that had feathers and could clearly fly.
