Fossil remains for this Dinosaur
have been found in Asia
Alectorsaurus
is another
Asian
ancestor of
Tyrannosaurus.
Alectrosaurus was only about half the
size of T. rex and it was more lightly
built - closer to Albertosaurus. It was
about 20 feet long and had a mouth full
of large, razor-sharp teeth that would
have made this a pretty ferocious
animal.
Alectrosaurus was discovered in 1923
during one of the American Museum of
Natural History expeditions to China led
by Roy Chapman Andrews. It was described
in 1933 and re-described in 1989. It is
considered to be a typical tyrannosaur
family member and may in fact be a
direct ancestor of Tyrannosaurusbataar.
Not much of this dinosaur has been
found, and some of the fossils that were
originally thought to belong to
Alectrosaurus were later determined to
belong to another dinosaur. |
