Quetzalcoaltus, means "Feathered serpent" is the largest pterosaur that lived in North America during Late cretaceous period.When first
discovered it was thought to have had a fifteen meter wingspan but
further studies have reduced this estimate to eleven meters, although
that’s still huge for a pterosaur. Another revision was the beak in
that it has been learned that it terminated in a sharp point as opposed
to the original blunt edge. A
more likely scenario
accepted now is that Quetzalcoatlus had a lifestyle
similar to that of
a stork, perhaps stalking small prey items like lizards and mammals
in vegetative growth on the ground, or sitting at the edges of
streams and rivers snatching fish and amphibians as they swam by.
Such feeding strategies would require very little energy expenditure,
making it easier for Quetzalcoatlus to maintain
the calorie intake
to fuel its body.
