Are you ready
for this
monster?
Seismosaurus was
the longest
dinosaur ever
discovered -
maybe. Not all
of it has been
found, so this
size is only a
guess that it
based on the
giant bones
discovered so
far.
An interesting
fact about
Seismosaurus is
that it was
found with over
200 gastroliths;
a particularly
large one of
these may have
caused its death
when it may have
lodged in its
throat and
blocked its
airway.
Seismosaurus
would have
looked very much
like a large
Diplodocus, and
in fact, may not
have been much
taller than a
more modestly
sized
Diplodocus. Its
legs were short
relative to its
total body
length -
estimated to
have been as
much as 180 feet
(54 m),
depending on the
number of caudal
vertebrae. |
