hi i'm andy and today i'm counting down
my top five greatest dinosaurs ever
hmm but which ones do i pick
there were big dinosaurs
[Music]
even bigger dinosaurs
tiny ones
scary ones
ones that ate meat
and ones that ate plants
wow
so picking my five favorites is possibly
my toughest challenge yet
but coming in at number five it's
[Music]
stegosaurus
i'd heard that stegosaurus flushed blood
into the enormous plates on top of their
backs in order to scare off other
dinosaurs so i went back 150 million
years to see that for myself
well that's the color of their plates
before they flush blood
[Music]
what's that
it's an allosaurus
these plates are changing color
that's it go on steak you show him
whoa watch out for that tail
you did it
flushing blood into those plates really
does work
right hold on to your hats things might
get a bit scary now because coming in at
number four
it's
spinosaurus
i went in search of a spinosaurus as i
needed a scan of it for a display back
at the museum and i knew just the place
to find one
oh he stopped for a drink
whoa
look
it didn't stop for a drink
it stopped to go fishing
that gives me an idea
right just need to wait for spinosaurus
to go for a swim
oh
here he comes
now's my charms
ready
[Music]
got it
okay next up the three horn plant
munching dino himself at number three
triceratops
i was on the lookout for a triceratops
horn to replace the one i'd broken back
at the museum when i came across two
battling triceratops that one's broken
its horn
now's my chance
perfect
[Music]
[Applause]
oh
no no no
patty's backpack it's always full of
useful things
[Music]
a fan
how's this gonna help me
unless
[Music]
it worked the bright color scared him
off
now for a dinosaur that grew up to be
bigger than a house
at number two it's
argentinasaurus
i was on an adventure with some
argentinosaurus
and i wanted to see the view from the
top of one
suddenly the opportunity presented
itself to me
going up
[Music]
still going up
wow
oh
one of you
on to our final contender he's big he's
fierce he has an almighty raw he's my
number one greatest dinosaur
t-rex
i traveled back 65 million years to
rescue my backpack from a hungry t-rex
[Music]
there must be something in here that he
wants
my sandwich
my meaty sandwich this is what he's
after
are you hungry
i guess you are here you go
it worked
oh i never did get to eat my lunch that
day
so there we have it my top five greatest
dinosaurs see you next time
you
