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 breakfastโ€ฆ another Tyrannosaurus rex by Rogue at Into Oblivion.

Check back next Monday for more miscellaneous selections!
