>> Well that's enough talking about how dinosaurs bones are not
preserved because here in Dinosaur Park,
we have literally millions of dinosaur bones exposed at any one time.
The majority of the bones are things like this.
They are just isolated vertebrae, bits of limbs, parts of limb bones, fragments.
They don't give us a tremendous amount of information about the animals and
they can also be very hard to identify because they've gone through these
processes where before they got fossilized, they may have been eaten by
another dinosaur or tumbled in a stream for many years before they got buried.
And then of course, once they've been eroded, they break up relatively quickly.
However when we walk around,
we also find a lot of isolated bones like that that are more interesting.
So for example, this is a tooth of a Trinosaur and
the Trinosaur is called Gorgosaurus.
We find many teeth in Dinosaur Provincial Park and that's because dinosaurs shed
their teeth throughout their life and in that way, they're very similar to sharks.
And so you can find that one animal could produce probably thousands of its teeth
in its lifetime and of course, they have a very good chance of being fossilized
because the enamel on the outside makes them quite hard.
Now a specimen like this can be identified, in some cases, right down to
the species level and consequently, we will take this back to collections.
When we find a fossil that we feel should go back to our collections, for example,
this ornithomimid,
or ostrich mimic toe bone, we have to record information about the specimen.
We'll take a little specimen card, and on the specimen card,
we'll mark a field number, and the identification is ornitha myabitombo.
