Terrapins exposed! Nature writes about turtles before the shells.
Darkfrog submitted, created time 3 days 22 hours (www.nature.com)
I particularly like the artist's depiction of the turtle ancestors. Even if, like most so many such drawings, it later proves to be inaccurate, it is a nice, vivid rendering. I particularly like that it shows the turtles as flexible, able to bend their bodies and necks. If I had to guess how this picture would turn out to be inaccurate, I'd say it's the heads. They're drawn with modern, meant-to-be-pulled-in turtle heads. 
Bacteria may play big role in forming fossils

Paleontologists were stunned when fossils appearing to belong to the soft-tissued embryos of marine creatures were unearthed in Chinese sediments a decade ago
Gene expression in alligators suggests birds have "thumbs"
sea-maid submitted, created time 1 month 2 weeks (esciencenews.com)
Scientists have long known that the bones in modern bird wings extend from cartilage that is homologous to fingers two, three, and four (pointer, middle, and ring) in humans. However, new information shows that early ancestors of birds, such as archaeopteryx, had wings based on one, two, and three (thumb, pointer, and middle) instead. Scientists now believe that modern birds are the result of a homeotic frame shift mutation.
Woolly mammoths native to what's now the U.S., says study
Darkfrog submitted, created time 2 months 3 weeks (sciencenow.sciencemag.org)
Recent DNA tests of preserved DNA have allowed us to sort prehistoric mammoths into three groups: One subspecies lived in Eurasia, one in North America, and another ranged through both. For a long time, it was thought that mammoths originated in Eurasia because the fossils that have been found there are older. While this seems to be true, the studies also show that the subspecies that arose in North America crossed the Bering Strait and supplanted the other two a few hundred thousand years ago.

Duck-billed dinosaurs outgrew predators to survive
sea-maid submitted, created time 3 months 1 day (esciencenews.com)
With long limbs and a soft body, the duck-billed hadrosaur had few defenses against predators such as tyrannosaurs. But new research on the bones of this plant-eating dinosaur suggests that...
T. rex "tissue" may just be bacterial scum
sea-maid submitted, created time 4 months 1 day (www.newscientist.com)
When palaeontologists reported that they had recovered soft tissue from a 65-million-year-old Tyrannosaurus rex fossil, the excitement was palpable.
Without going all Jurassic Park, the discovery seemed to open the door to studying biomolecules from dinosaurs and other long-extinct creatures.
It seems, however, that no one will be cooking up a new zoo exhibit from this one. The "tissue" appears to have been layers of biofilms laid down by bacteria and not the skin and flesh of the ancient beastie
Big brains arose twice in higher primates

After taking a fresh look at an old fossil, John Flynn, Frick Curator of Paleontology at the American Museum of Natural History, and colleagues were able to confirm the theory that large brain size has developed more than once in the primate evolutionary tree.
Rodent Bones of Contention--When Did Humans Reach New Zealand?

Dinosaurs are shown to be related to birds, not reptiles
Darkfrog submitted, created time 7 months 3 days (www.nytimes.com)
Genetic testing reveals a connection between the Tyrannosaurus rex and living birds such as ostriches and chickens and NOT other reptiles, such as alligators, something that has long been suspected from skeletal data.
It doesn't come as a shocker at this point, but it's nice to know.
Fossilized jaw shows that hominids lived in Europe earlier than we'd thought
Darkfrog submitted, created time 8 months 4 days (www.nature.com)
The article names the single-find specie "Homo antecessor" and hypothesizes descent from Homo erectus, saying that some Homo e left Africa for Asia, then quickly doubled back to Spain.
This changes the system of ideas surrounding genus Homo's entrance into Europe. Previous fossils gave a date of as early as 800,000 years ago, but this mandible dates to 1.2 million.
Giant frog found in Madagascar
sumsung submitted, created time 9 months 1 week (www.nature.com)
A giant frog that hopped around Madagascar 65–70 million years ago has been discovered. Fossil fragments show that the frog, called Beelzebufo ampinga, could have measured 20 centimeters across its squat head, and probably more than 40 centimeters from snout to tail. The researchers nicknamed the monstrous beast "the frog from hell"; the official name comes from one of the many names for the devil (Beelzebub) and the Latin for "toad" (bufo).
Ancient bat flew without echolocation
sumsung submitted, created time 9 months 2 weeks (www.nature.com)
Among those who study the evolution of bats, the question of whether the bats developed echolocation and then flight, flight and then echolocation or developed both traits in tandem is a matter of great debate. A discovery in Wyoming not long ago has tossed some more gas on that fire.
The 52.5-million-year-old bat unusually had a claw on all five digits of each limb, earning it the nickname "20-clawed bat." Its anatomy shows that it captured its prey without the use of echolocation. The echo-first campers have yet to respond.
Did Insects Kill the Dinosaurs?
sumsung submitted, created time 10 months 2 weeks (www.time.com)
By now, scientists have a pretty good idea of what conditions were like in the Cretaceous period, which started about 135 million years ago, and came to a sudden end 70 million years later, with the death of the dinosaurs. Or rather, they think they do — but two new sets of research results suggest there's a lot more to learn.
Whales may have evolved from raccoon-sized creature

In the search for a missing evolutionary link to modern whales, scientists have come up with an unlikely land cousin -- a raccoon-sized creature with the body of a small deer.
Long-Lost Relative of Whales Found?

A group of paleontologists has identified what they believe is the closest relative of whales, dolphins, and porpoises--an extinct, raccoon-sized creature that sloshed along river bottoms and could have eaten like a landlubber. The find promises to give scientists a better idea of where whales and their ilk came from.
