the Jurassic world franchises brought to life some most iconic dinosaur species of all time I'm sure
that we all have our favorites perhaps yours is the giant yet gentle Brachiosaurus and how its
first appearance on screen will forever be hailed as one of the most awe-inspiring moments in cinema
history or maybe it's the highly intelligent velociraptors and the heart racing suspense
we all feel whenever they cleverly escape from their electrified enclosures on this adventure
we're going to take a historical look at some of the film's most beloved dinosaurs by admiring the
fossils they left behind and the wonder they bring to our imaginations to truly understand the size
and magnitude of a dinosaur you must simply put yourself in the presence of one skeleton
perhaps the best place in the nation to do just act is the Chicago Field Museum this renowned
location maintains one of the world's largest collections of artifacts and specimens and it's
their iconic haul of dinosaurs that will make the perfect backdrop for this episode joining
me on this journey is Bryan sweet mo Bryan is Jurassic world's resident paleontologist
he has participated in numerous dinosaur digs across the United States has authored several
books and is considered an expert when it comes to prehistoric creatures upon entering the Hall
of dinosaurs we were immediately drawn to one of Bryan's all-time favorites one of the true
icons from the Jurassic period and of course the dinosaurs we recognized franchise now even as a
plant-eater this is a pretty dominant creature to have walked our planet and it's got really cool
features the plates and the spikes what are those plates for was a lot of different idea
so when it was first found is that those plates look laid flat over its back that's why I stick a
source means roof lizard later they found better specimens those plates are sticking straight up
so they rearrange those plates but that only really deepened the mystery about what this
animal is doing so at first it seemed that was for thermoregulation that Stegosaurus get turned
towards the Sun heat up in the morning if it got too hot turn away from the Sun dump all that heat
turns out that probably not the case it seems more for display so this is probably big intimidating
maybe showing off to potential mates you know trying to scare away rivals so the mystery
remains like we know that they work for something but the question is what now during the Jurassic
period this dinosaur had potential predators like the Allosaurus and if you were to defend yourself
against an Allosaurus obviously that tail would be the weapon of choice oh yeah that's a pretty
good way to do it so you've got those four spikes that have been covered with Caribbean life that's
the same stuff that covers your finger named after your nails are made of so there would've been even
more imposing while this animals live and swing that tail swing those spikes about 40 meters per
second so that's enough to pierce through bone and we actually have an Allosaurus bone with a hole
in it just the right size for a Stegosaurus tail spike so we think that this particular
carnivore was trying to sneak up and they got the business and the Stegosaurus walked away limping
and learned his lesson Wow crazy okay now and I think if stegasaurus tail it certainly reminds
me of that scene in Jurassic Park the lost world when Sarah Harding has to dive into that log now
the spikes come down on top certainly one of my favorite scenes but what is your favorite scene
Insectosaurus appear to I think might have to be just a couple of moments before when she finds
that baby because it's against the law as I said my eyes it's not a hatchet Venegas ought to grow
up and there though they were cute then big eyes and the puppy-dog face a baby Sega stars who have
been absolutely adorable just right okay well let's move on from the Jurassic period and head
toward the Cretaceous and see some other of those pretty cool dinosaurs absolutely let's do it over
the course of millions of years as the Jurassic transitioned into the Cretaceous period evolution
gave rise to some of the most dominant dinosaurs to have ever roamed our planet and one of them
certainly needs no new introduction Triceratops certainly one of my favorites and without question
one of the most recognizable dinosaurs throughout history and of course the Jurassic franchise I
mean what would drastic be without at least the sick Triceratops alright I'm interested ops has
pretty much been in every single movie in some way shape or form when we look at this dinosaur as we
know it's an herbivore but it's such a dominant figure in dinosaur history and as people look
at it you think well obviously the horns and the frill let's talk about those features now
when I look at the horns obviously that's used in battle or to defend itself against predators
but the frill is the one that I think probably has the most question absolutely there's been
a lot of ideas about what that frill is for and it seems to be related to combat which he just
brought up so these dinosaurs rather than fighting other species of dinosaurs are most often fighting
each other well we walked up to this skeleton we looked at Wow like such an iconic dinosaur
throughout the entire film franchise and certainly for me the first moment when Grant and Sadler Tim
and Lex knocked a mountain they all walk up and see the sick Triceratops and Grant lays down on
top of it I just absolutely loved that moment was the first moment where human contacted dinosaur I
think it's moment none of us will ever forget how about you what's your favorite Triceratops
my walk I'm gonna go with the gross ones you go Triceratops isn't actually in the scene but
the pile of Dino droppings because that makes it a real animal like source poops just like
any other animal does and I you know they're looking for what it ate to see why it was sick
and just it was a biological twist to it that turned it more into a real animal and not just
like a prehistoric monster so Brian everyone loves dinosaur battles and we were talking stegasaurus
versus Allosaurus in the Jurassic period certainly the battle everyone wants to see and rotation with
Triceratops versus Tyrannosaurus Rex but how often would these two Titans have actually clashed it
did happen but probably not in the way that you might think so it's probably not an adult t-rex
vs. adult Triceratops very often that would have been incredibly dangerous for an adult
ran sort of go after an adult in Saratov it's like a lone wolf going after an adult bison or a lone
line going after an elephant at that kind of board that's hurt and they can't hunt anymore that's it
for them so t-rex is probably much like a modern carnivore in that sneak is probably going after
the juveniles and the babies and all these little Triceratops I haven't grown up yet and that might
be part of the reason why we don't have very many guns Triceratops no part of that reason
that we don't find them is that they're getting now I know if I was a baby Triceratops I would
certainly be doing my best to avoid a predator I'd like to ran a source Rex which is probably a good
point for us to transition into seeing what the audience has all showed up are you ready I'm so
ready here we go this was the moment we had both been waiting for the chance to see the world's
biggest best preserved and most complete t-rex skeleton before its new exhibit officially open
to the public the one the only sue the largest Tyrannosaurus Rex skeleton ever how about that
yes well here's what I think we should do Brian let's start at the tail and move our way towards
the skull in total sue measures 40 feet length and stands 13 feet tall at the hips the walk
alongside the skeleton is absolutely breathtaking and it really brings into perspective just how
big a predator like Tyrannosaurus Rex truly was look at the size of this thing it is absolutely
massive so big it barely fits in the room right so there's about 40 feet long that half of that
length is tail it's like it's a giant seesaw just with teeth up one okay so basically for
balance that's right counter balancing of all that needs stuff on the other end of the enemy okay so
tail exciting works for balance but then we get into the feet guys look at these feet absolutely
can you imagine it to stop down by t-rex I'd rather not really was t-rex really capable of
moving 32 miles an hour not quite I'd say 12 to 25 well when they can decide how fast humans can run
that's still far more than needed to outpace us okay now certainly the feet of Tyrannosaurus Rex
played such a crucial role throughout all the Jurassic films just being able to add suspense
like in Jurassic Park when the t-rex walks into the scene and that foot squishes down into the mud
of course in the lost world when that one guy gets out Donna gets stuck in the foot that was pretty
crazy and then of course we fallen Kingdom I love that moment with Carnotaurus when it pinned down
and exactly aside from walking that's what these feet are good for think about birds today how they
use their feet they do very much the same thing you come down with that foot and then you put
the jobs to work right sue is around 90% complete containing 224 of the 321 known bones in a t-rex
skeleton including the furcula or wishbone and the gas trolley which is a set of rib like bones that
are believed to have helps you breathe let's see what it's like to look down the snout of taranis
so frightening rats look at that skull t-rex was things about this skull binocular vision this was
a dinosaur if you look directly at you not from the side it's there straight down right now what
about the theory of visual acuity being based on movement so that was based upon frogs they need to
sneak up on the Fridays I'm sure you're familiar was sure they don't see you because they can't see
behind them right so because he was product DNA in the films that got transposed over to t-rex so
if you were backing for tatius period 16 million years ago just walking through the woods house yes
they would see you so he's in Woodstock still they still see you and smell you is fine okay so that
sense of smell that moment I love that moment so much suspense in Jurassic Park when the 2x comes
in dr. Grant's head it loads out of his head so the t-rex really would have been able to smell you
in them oh absolutely that was t-rex exciting not to have a snack ah I see well I guess it worked
out pretty well for the film but when you look at sue look at the structure of this skull its
massive and you can see how a human could easily fit right into the mouth of this dinosaur well
that's just pulverizing bite forces we're talking about 8,000 pounds of pressure so almost if this
animal stepped on you that's the same amount of weight as it's putting behind those jobs okay so
if the stock didn't kill you the jaws would come out and finish the job when you stand beneath sue
and look up into that mouth filled with teeth it's a horrifying thought to picture the skeleton fully
fleshed out with muscle and skin well Brian thank you so much for leading us on this journey today
where we looked at some of the icons from the Jurassic franchise from stegasaurus to
Triceratops and ultimately landing on the king the dinosaurs Tyrannosaurus Rex I'm coyote Peterson
be brave stay wild we'll see on the next Jurassic world adventure sue is considered to be the crown
jewel of the field museums collections and for myself Brian and the Jurassic world explorers
it was an honour to visit this exhibit before its opening and it is now our incredible pleasure to
announce that Sue's new exhibit will officially open to the public on Friday December 21st with
the discovery of dinosaur skeletons like sue it's easy to see how creative minds have been
inspired to bring these prehistoric icons back to life through films like Jurassic world if you
love the Jurassic franchise as much as we do then make sure to go back and watch the films
from Universal home entertainment it sparked an adventure 65 million years in the making this
collection is now available on blu-ray DVD and Digital Download hey dinosaur fans travel back
in time to last week's episode as we take you behind the scenes at the Chicago Field
