had a very large head filled with somewhere between 70 and 80 knife-like
somewhere between 70 and 80 knife-like
somewhere between 70 and 80 knife-like teeth today we’re working on the
teeth today we’re working on the
teeth today we’re working on the Allosaurus which is on exhibit here at
Allosaurus which is on exhibit here at
Allosaurus which is on exhibit here at the Smithsonian the amount was put up
the Smithsonian the amount was put up
the Smithsonian the amount was put up about 1981 and what is due for is a nice
about 1981 and what is due for is a nice
about 1981 and what is due for is a nice new pose and bit of an overhaul
the mounts that were used in the hall
the mounts that were used in the hall have been in their same postures
have been in their same postures
have been in their same postures basically since they were mounted
basically since they were mounted
basically since they were mounted anywhere from the early 1900s
anywhere from the early 1900s
anywhere from the early 1900s through 1940s 50s and 60s and since then
through 1940s 50s and 60s and since then
through 1940s 50s and 60s and since then we’ve learned a lot about dinosaur
we’ve learned a lot about dinosaur
we’ve learned a lot about dinosaur Anatomy we found out a lot more about
Anatomy we found out a lot more about
Anatomy we found out a lot more about their postures and their physiology and
their postures and their physiology and
their postures and their physiology and so we need to update the information
so we need to update the information
so we need to update the information that’s in our paleo halls to reflect
that’s in our paleo halls to reflect
that’s in our paleo halls to reflect current knowledge of paleo biology we do
current knowledge of paleo biology we do
current knowledge of paleo biology we do a little bit of tracking on the bone so
a little bit of tracking on the bone so
a little bit of tracking on the bone so soon LED Zack was going to each case and
soon LED Zack was going to each case and
soon LED Zack was going to each case and each crate and then its label to mark
each crate and then its label to mark
each crate and then its label to mark the basic idea is to dismantle it in
the basic idea is to dismantle it in
the basic idea is to dismantle it in reverse order that it was assembled on
reverse order that it was assembled on
reverse order that it was assembled on the hall so generally the head comes off
the hall so generally the head comes off
the hall so generally the head comes off first you got to figure out how the head
first you got to figure out how the head
first you got to figure out how the head was attached and then the tail and then
was attached and then the tail and then
was attached and then the tail and then you just kind of work your way in
for dismantling to be shipped to another
for dismantling to be shipped to another place you want to get pieces off in sort
place you want to get pieces off in sort
place you want to get pieces off in sort of bigger chunk as possible like an
of bigger chunk as possible like an
of bigger chunk as possible like an entire rim bone might come off as one
entire rim bone might come off as one
entire rim bone might come off as one unit then be packed up and a couple of
unit then be packed up and a couple of
unit then be packed up and a couple of points of look like we’re coming to the
points of look like we’re coming to the
points of look like we’re coming to the actual fossil but but it wasn’t it was
actual fossil but but it wasn’t it was
actual fossil but but it wasn’t it was gas material how it was mounted they
gas material how it was mounted they
gas material how it was mounted they they ran a steel armature through the
they ran a steel armature through the
they ran a steel armature through the centre of the bone so it grows on a
centre of the bone so it grows on a
centre of the bone so it grows on a string all the way through so we had no
string all the way through so we had no
string all the way through so we had no choice but to go through there with a
choice but to go through there with a
choice but to go through there with a saw once the owl source is dismantled
saw once the owl source is dismantled
saw once the owl source is dismantled here it will be packed up very carefully
here it will be packed up very carefully
here it will be packed up very carefully and shipped to a company called our CI
and shipped to a company called our CI
and shipped to a company called our CI research casting International and they
research casting International and they
research casting International and they have a facility outside Toronto Canada
have a facility outside Toronto Canada
have a facility outside Toronto Canada where they specialize in developing and
where they specialize in developing and
where they specialize in developing and reconstructing dinosaur mounts so it’ll
reconstructing dinosaur mounts so it’ll
reconstructing dinosaur mounts so it’ll spend some months there as they do that
spend some months there as they do that
spend some months there as they do that they’ll create a metal armature for the
they’ll create a metal armature for the
they’ll create a metal armature for the skeleton then the whole thing will get
skeleton then the whole thing will get
skeleton then the whole thing will get dismantled again brought back here and
dismantled again brought back here and
dismantled again brought back here and installed in the new hall when that’s
installed in the new hall when that’s
installed in the new hall when that’s ready this is probably one of the best
ready this is probably one of the best
ready this is probably one of the best jobs we’ve had you know you can’t be
jobs we’ve had you know you can’t be
jobs we’ve had you know you can’t be coming down to Washington DC working
coming down to Washington DC working
coming down to Washington DC working with the National collection and we’ll
with the National collection and we’ll
with the National collection and we’ll treat it right and you know when the
treat it right and you know when the
treat it right and you know when the animals come back they’ll just be
animals come back they’ll just be
