The first record provides evidence at
how creatures change over time
millions and millions of years however
time has not changed how the fossil
record
is found the way we find dinosaurs in
the same way we have
for centuries we get out we walk around
on the ground and we look
the better I said the ground and look
for awful sticking out sell
as you're walking around sometimes for
days I'm per week
and not finding anything and he in and
rainy decide here you never know when
your gonna turn at him
and you're gonna find something
incredible keeps you going every single
day
and in the dry
barren Cedar Mountain Formation in
central Utah
doctor Lindsay's shadow has discovered
incredible creatures
that lived long ago you know you have to
understand your past understand where
you're going we
live on a dynamic planet changing we
wanna know
what it's gonna be like in the future
and what we should do about it and what
we should protect
and had fit in with their own ecosystem
at best record we have a that if the
evolution of life
on the planet four billion years up
actual date
there's a rich story to be told about
this area
it resembles a moonscape now but
apostles reveal
the landscape was once the lush and wet
coastline
up the Kuttanad it was filled with dense
vegetation in a variety of reptiles
amphibians and dinosaurs
radiometric dating a volcanic rock found
here
set that time between $100 million and
sixty
million years ago that much is known
about the creatures that lived in this
aged Earth's history and almost every
discovery
is new to science and this animal was
living right along the coast
term each bomb if you will and early
cretaceous
doctors and 0 hopes to introduce this
new species a
duck-billed dinosaur to the world this
year he estimates the creature lived
about $78 million years ago
it was about 25 feet long in stood about
20 feet tall
but it's a gorgeous best minute I would
have been here has
at a large come to know that
humped knows looked a lot like a bird
beak
brown material you're looking at is
fossilized bone
grey material in between in sandstone
had a bill and a peek at the front
ate here in atlanta grinding teeth
toward the back the dow
the creature was a plant leader and it
had plenty
have deep and in fact had at dental
batteries a
hundreds to possibly thousand T each
individual that were continuously
replacing and baby
lives they horrible stuff a tam
bank owned and bark and pine needles in
the sorts of things and the ground 30
down but they could continuously replace
think Ive paleontology is a kind of
prehistoric
forensics latest look for clues that
reveal
that only how animal lived but also what
happened to it
when it died they ask questions such as
what its cabbage depart didn't lay in
the Sun
was it very quickly before its soft
tissue decomposed
the answers reveal what the ecosystem
and the environment was like
where the dinosaur lived and died to
make sure
all that information is recovered
researchers
leave the possible in case in the
sediment they were buried in
the red everything in a protective
plaster shell
and bring it all back to the lab for
study so this animal
died and was buried in a river I was
probably buried
fairly quickly and but it didn't had a
chance for senate soft tissue to
decompile
most the duck-billed dinosaur skeleton
was discovered
this is a bone from the top of the
vertebrae this is a toe bone
this bone made the tip of the tail these
are its ribs so
fleck by flak at the point to be sharp
to all with the
bristle brush or the world in air drill
the bone is uncovered the dinosaurs
story is Paul paleontology is a study in
time
in patients and at the North Carolina
Museum of Science
volunteers are trained to help
scientists discover
the fossil story actually Bisco is
uncovering
a prehistoric colonel and right now I'm
kinda chiseling away
piece by piece a little bear at some
other
matrix and revealing what we have their
because it is so fragile and fallen
apart on
having to go and consolidate make sure
the ban stays together
where it's at so we can get a better
idea
about it actually looks like this is a
of Famer from of elk areas which is
about 125 million years now
on said this is the bomb heartened that
in the middle has like and this will fit
on the top because as if this we think
this one is relatively young
Subhan working on a maybe a teenager
yes this is about 125 million years ago
and the three love it is to be able to
touch
and feel something at $225 billion years
ago
it's just amazing the
it can take three to five years or more
to recover a fossil in the field
and then bring the specimens back to the
lab with the settlement is removed
and bones are studied but what a story
the fossils can tell but this best man
right here has bite marks on it
and so some of these animals were
definitely being eaten whether or not
they were killed
and many or if they died and were
scavenged
it's hard to tell but there's definitely
evidence that something was not going on
this bone he can
look right here you can see the there's
two holes right here those are bite
marks on this
particular bomb in each bone fragment
tells
a story it feels in just a bit more
the mosaic the picture up for its
history
you re-direct here your hair and has
kinda time scales but we have to work
in that kinda dimension and it for a
even to graph
that but when you look at real person is
we'll have a table
that I have of a line it better 119
years tiny
each time we dig one up. its list tiny
little piece of that puzzle that allows
us to
it when I spoke to get we get better
understand
