Apatosaurus could run on two legs!

03-11-2010 8:11pm#1Well, baby ones anyway - possibly.Surprising to Mossbrucker and colleagues is that the running trackway demonstrates only hindpaw tracks. "Perhaps while the little dinosaur was running the hindpaw eclipsed and crushed the frontpaw track leaving no trace, or perhaps this critter was running only on its hind paws," Mossbrucker said. The walking-gait tracks do show a forepaw track"
......
"In the end, we might have a baby sauropod that is running like a Basilisk lizard, a modern lizard that is mostly a quadroped, but when spooked it runs on its hindlegs," Mossbruker said.
Studies are underway to understand the biomechanics of Morrison's sauropods and what a running baby sauropod would look like.
