ResearchBlogging editor’s selections: Aboriginal astronomy, the CO2 climate knob, the pain files, and cannibal Tyrannosaur X2

skyskull “Dr. SkySkull” selects several notable posts each week from a miscellany of ResearchBlogging.org categories. He blogs at Skulls in the Stars.

Sorry for a late batch of selections this week!

Finally, just when you couldn’t imagine that Tyrannosaurus rex couldn’t get any more intimidating, comes strong evidence that the creature was also a cannibal when it needed to be! We look at two different accounts of the research: Tyrannosaurus the Cannibal, by Brian Switek at Dinosaur Tracking, and When Tyrannosauraus rex had for breakfast… another Tyrannosaurus rex by Rogue at Into Oblivion.

Check back next Monday for more miscellaneous selections!
