Dinosaur footprints were found on the cave of a ceiling at Mount Morgan in Queensland, Australia in 1954. TORONTO -- A dinosaur-related puzzle that baffled scientists for more than half a century has been solved.

Scientists were able to date the footprints back nearly 200 million years, to the early Jurassic era, but what confused them was that it seemed to show the dinosaur walking on all fours – an implausible behaviour, according to University of Queensland paleontologist Anthony Romilio. The lack of further clues from the cave at Mount Morgan left scientists unable to determine whether the prints were some sort of aberration, or surprising evidence that dinosaurs might have once been quadrupedal.The dentist, Roslyn Dick, told him that her father had been part of the Mount Morgan research, and that she and her sisters had held onto his work.

Recognizing Staines as someone who was indeed involved with the Mount Morgan discovery, Romilio's curiosity was piqued. When Dick showed him the notebooks and photographs her father had left behind – including a plaster cast of a dinosaur footprint kept in her sister's cupboard – he realized he could finally piece together the puzzle.

Scientists sure must be a stupid lot if they couldn't come up with that scenario in less than a minute, let alone 50 years. Me: what's the difference between an elephant and a bunch of bananas? Scientists: We're not sure, give us time. Me: Remind me not to send you to the grocery

I know this will sound dumb. But Im still not getting how the ended up on the ceiling....

Full NFLPA membership to vote on owner-approved CBA - Sportsnet.caThe NFL moved closer to labour peace for another decade early Wednesday when player representatives voted to send a new deal already approved by the owners to the full union membership. Really hope this doesn’t pass. I don’t want a 17 game season or more playoff teams, not to mention the players need to have some/all of Goodell’s discipline power taken away.
