in 2019 Robert finds something truly
[Music]
remarkable see the cracks already
forming look at that so we're going to
have to really monitor that before we
glue it cuz this is getting vulnerable
now an almost complete
creature after 66 million years finding
anything intact is extremely
rare Matrix CL get the consultant and to
get this block out we're freezing
it to keep the fossil in one piece as
they remove it from the crumbly laay the
team decides to use a potentially tricky
technique they've covered the fossil in
plaster to protect
it Daddy freeing it means they have to
flash freeze the crumbly Rock
surrounding it
using liquid nitrogen at around - 300°
F watch your
footing Lauren I'm worried about
brittleness here get that hammer give
this a couple waxs with the
hammer okay move over 5 cm
good it's cracked
loose yep okay it's loose loose so we
have to get this out in one piece 1 2

3w total success total
success this is a technique used in
archology for digging up human remains
we've got enough time to work with the
fossil and not damage it and I couldn't
be
happier and the creature Robert and his
team have found
a
turtle this is the fossil now it's being
cleaned up it's lying on its side here's
the outline of its
shell the shape of the shell and the
sculpt edges here tell us that this was
a bined
turtle this bined Turtle would have
looked very similar to modern couta
Turtles and lived in the same sort of
freshwater
[Music]
environments the late Cretaceous Period
is kind of the Heyday of turtles in at
least Northern North America um there
were at least 16 species that were known
from
Saskatchewan um and compare that to
today we only have three so back then it
was a much better time to be a turtle
