To: Renfield
Reappraisals of pterosaur trackways and limb joints in the 1980s and 90s finally laid parts of the controversy to rest, confidently demonstrating that pterosaurs walked on four limbs held almost vertically beneath the body. This energy-efficient stance is reminiscent of the limb carriage in most birds and mammals, rather than the sprawled limbs of modern reptiles.
Four legged birds?
