Megalancosaurus
is one of the better known of the drepanosaurs, a special group of
reptiles that possessed tails that could hook around branches. With
an additional hook on the end of their tails, Megalancosaurus
are
believed to have walked along the branches of Triassic era tree
canopies, hunting for small invertebrates to eat.
Megalancosaurus
is noted for having a bird-like skull, in fact Megalancosaurus
was
even once considered to possibly be an ancient ancestor of birds until
the remainder of the skeleton was discovered and that idea was
disproved once and for all. The slender jaws of Megalancosaurus
were
probably instead used to reach into tight recesses to pluck out hidden
invertebrates.
