Quadrupedal

Now we have the possibility that the chimps and gorillas may actually be on their way from a bipedal ancestor to a quadrupedal descendant! ❋ M_francis (2009)

Food for myself and the various quadrupedal residents of my house has been procured. ❋ Kat Howard (2010)

The sight of the armored, snorting, quadrupedal intruder, eyes bloodshot and nostrils flaring in the moonlight, gave even the belligerent Krasvin pause. ❋ Sugu Althomsons (2010)

Chimpanzees, which are mostly quadrupedal, do not show these vertebral adaptations. ❋ Unknown (2007)

Tupandactylus imperator by Mark Witton - quadrupedal "bat" model ❋ Nima (2009)

BTW, a few quadrupedal pterodactyloid trackways - assuming they exist - don't DISPROVE bipedality - especially with creatures as light as pterosaurs. ❋ Peter Bond (2009)

He draws all of them as quadrupedal, and I know for a matter of fact he knows what he is talking about he works with Conway a lot from what I've gathered. ❋ Peter Bond (2009)

And of course, wherever you go out of doors, your quadrupedal pal can follow. ❋ Unknown (2009)

They are often seen mocking the second group, which treats their dogs as quadrupedal, slobbery people. ❋ ALEXANDRA HOROWITZ (2009)

We have to admit that the fossil record connecting the upright-walking ape Australopithecus to the presumably quadrupedal ancestor that we share with chimpanzees is still poor. ❋ RICHARD DAWKINS (2009)

And the biomechanics of such a thing would be overstressed to the point of fantasy, especially in a quadrupedal crawling pose. ❋ Nima (2009)

I don't reject the mere possibility that SOME pterosaurs were quadrupedal at least SOME of the time - but I simply don't buy the model of bat-winged pterosaurs clumsily shuffling along with their leg movements hampered at every turn by overstretched wing membranes. ❋ Peter Bond (2009)

Could anyone really believe that a quadrupedal animal would give birth to an animal with three limbs, one of which was a leg adapted for bipedalism, and then have to wait to fro the second leg to ‘evolve’ whatever that would mean in that context? ❋ Unknown (2009)

While still quadrupedal omnivores, the range of body types and sizes among dogs is extraordinary. ❋ ALEXANDRA HOROWITZ (2009)

Anything that big would have needed a running bipedal takeoff with legs FREE of all restraint, EVEN if it was normally quadrupedal on the ground which I don't really dispute in any case - big Pterosaurs were probably too top-heavy to be full-time bipeds. ❋ Peter Bond (2009)
