Australopithecus Sediba Paved the Way for Homo Species, New Studies Suggest
ScienceDaily (Sep. 8, 2011) — Researchers have revealed new details about the brain, pelvis, hands and feet of Australopithecus sediba, a primitive hominin that existed around the same time earlyHomo species first began to appear on Earth. The new Au. sediba findings make it clear that this ancient relative displayed both primitive characteristics as well as more modern, human-like traits. And due to this “mosaic” nature of the hominin’s features, researchers are now suggesting that Au. sediba is the best candidate for an ancestor to the Homo genus. (click thru picture to read more)

Pregnant fossil reveals lots about plesiosaurs
A recently discovered fossil of a plesiosaur (think a marine turtle crossed with a giraffe) with a fetus still inside sheds quite a bit of light on the ancient creature. The dinosaur is pretty clearly pregnant - the fetus is too large to have been swallowed, of the exact same species, and doesn’t appear to have been chewed or digested. The find does reveal that plesiosaurs laid live young and invested heavily in a few young. The authors of the finding also speculate that plesiosaurs may have lived in social groups, like pods of dolphins.
