allosaurus is a predatory dinosaur from
the late jurassic period about 145 250
million years ago tended to be about 30
feet long and it could weigh anywhere
from 1500 to 2000 pounds it had long
arms that were used for grasping prey so
they had three sharp claws on them and
had a very large head filled with
somewhere between 70 and 80 knife like
teeth today we’re working on the
Allosaurus which is on exhibit here at
the Smithsonian the amount was put up
about 1981 and what’s do for as a nice
new pose and they’d have been overhauled
the mounts that were used in the hall
have been in there same postures
basically since they were mounted
anywhere from the early 1900’s through
1940s 50s and 60s and since then we’ve
learned a lot about dinosaur Anatomy we
found out a lot more about their
postures and their physiology and so we
need to update the information it’s in
our paleo halls to reflect current
knowledge of paleobiology we do a little
bit of tracking on the bone so soon led
Zach was going to each case and each
crate and then its label to mark the
basic idea is to dismantle it in reverse
order that it was assembled out in the
hall so generally the head comes off
first you gotta figure out how the head
was attached and then the tail and then
you just kind of work your way in
for dismantling to be shipped to another
place you want to get pieces off in sort
of bigger chunk as possible like an
entire limb bone might come off as one
unit can be packed up and a couple of
points of looked like we’re cutting to
the actual fossil but but it wasn’t in
this gasps material how it was mounted
that they ran a steel armature through
the center of the bone until it grows on
a string all the way through so we had
no choice but to go through there with a
saw once the owl source is dismantled
here it will be packed up very carefully
and shipped to a company called rci
research casting international and they
have a facility outside Toronto Canada
where they specialize in developing and
reconstructing dinosaur mounts so it’ll
spend some months there as they do that
they’ll create a metal armature for the
skeleton then the whole thing will get
dismantled again brought back here and
install them the new hall when that’s
ready this is probably one of the best
jobs we have you know you can’t be
coming down to Washington DC working
with the National collection and we’ll
treat it right and you know when the
animals come back they’ll just be
spectacular display
