T-Rex vs Spinosaurus Fight Simulation | 3D Face-Off In-Depth Analysis

it is the most disputed dinosaur matchup

in history a rival never witnessed in

the real world but recreated and

imagined by millions the battle between

the most terrifying predators ever seen

the tyrannosaurus rex versus the

spinosaurus today we will uncover the

hard stats studying these two extinct

predators in detail while analyzing

their attack methodologies agility

terrain and other auxiliary weapons that

will dictate who will survive to see the

next day and who will cease to exist for

the very first time we'll witness all

data discussed here compiled into a

combat simulator featuring both

dinosaurs in a fight to the death coming

up tyrannosaurus rex versus the

spinosaurus

corporal builds

this battle has been a topic of debate

for decades but only seen on screen with

renditions that are now considered

outdated today the simulator will be

using relatively updated renditions of

these two dinosaurs beginning with

tyrannosaurus rex throughout the years

it has been believed that this theropod

was one of the largest of its kind

dwarfing all of its predecessors in this

simulation we will be taking into

account the sizes of two of the larger

specimens recovered maxing out this

t-rex to up to 13 meters in length in

terms of height this creature would have

measured four meters at the hip you will

notice how this newer rendition of the

t-rex is actually much bulkier than the

pop culture depictions seen in films and

previous documentaries as seen here this

creature's bone structure also reflects

its heavy build allowing this creature

to weigh as much as 8.9 000 kilograms or

approximately up to 9.7 us tons given

its proportions this creature now ranks

as one of the heaviest and largest

theropod predators in history

its opponent the spinosaurus has been

the topic of much discussion throughout

the last 20 years due to its

ever-changing dimensions body shape and

capabilities we now know thanks to the

most recent studies that this theropod

was actually a bit more robust than what

we imagined back a couple of years ago

we will be taking these spinosaurus's

remains when generating a contestant for

this simulation giving us a dinosaur

that can reach lengths of up to 15

meters and a height of 2.3 meters 5 at

the tallest spine weight wise the

results are a bit surprising well it is

true that the spinosaurus has a

seemingly lighter build than the t-rex

recent estimates have placed the

spinosaurus's weight from 7 to 8.3 us

tons to around 10 tons this was due to

many factors seen through more recent

digital models that suggest that this

creature was more stockier than

anticipated in addition to that a new

study released in 2022 stated that this

animal's bones were much more dense

which would also contribute to its heavy

build by putting these factors into

account we see that the difference

between corporal dimensions has now

diminished considerably compared to

previous assumptions the next thing to

analyze is how these builds aided in

their forms of movement agility and

speed

[Music]

locomotion

well it is obvious that the

tyrannosaurus was clearly adapted for

terrestrial locomotion its actual speed

on land has been fiercely disputed

recent computer modeling and other

analyses have concluded that an adult

t-rex was not capable of running as we

know it it wasn't able to perform a

running gait which is the act of having

both feet off the ground while running

but it could do what is known as a fast

walk

recently it's now estimated that a t-rex

at full speed could reach anywhere

around 5 meters per second or 11 to 18

miles per hour although this may not

seem very fast recent studies have found

evidence that this t-rex was more agile

than we think not too long ago a group

of researchers argued that this

dinosaur's ilia the bone in the upper

part of the hip was adequate for

allowing the rex to pivot from one

direction to another like a figure

skater from hell the team took into

account centers of mass to rotational

inertia making the t-rex's agility score

higher compared to other similar sized

theropods

unfortunately for spinosaurus there are

no published reports on the spino's

maximum speed on land but based on its

reduced leg size we can guess that this

creature was not a terribly fast mover

possibly moving to speeds slower than

the t-rex or equal at the most the

obvious go-to for a locomotive advantage

would have been a nearby body of water

yes there has been debate on whether the

spinal was a good swimmer but again the

study mentioned earlier gave further

evidence that this dinosaur could not

only swim well but also dive deep into

the water this dinosaur was said to have

osteosclerosis which is a condition of

having denser bony material

this was also accompanied by possible

pachyostosis which is the thickening of

certain bones apart from being able to

submerge itself this animal's tadpole

paddle-like tail was evidence that this

animal could move through an aquatic

environment and capable of exerting

eight times the force of other theropods

but what about the t-rex new evidence

discovered by scott persons and team

suggested that this animal could in fact

travel by water from time to time thanks

to claw marks on a riverbed that were 50

feet apart from each other but not well

enough like its rival the spinosaurus

now that we know how these creatures

move let's quickly go over how well

these things can stay upright

stability

getting tipped over in a fight with

dinosaurs of these dimensions could be

fatal by observing both of these

creatures centers of gravity we find

that the t-rex's was located in a much

higher position than the spinosaurus

proportionally this means that the spino

does indeed have a wider stance thanks

to its shorter legs and auxiliary front

limbs because of this if both t-rex and

spino were hit in the same location the

spinosaurus would be harder to knock

down not to mention that recent

observations also suggested that this

spinosaurus could rear up on its hind

legs and use its tail as a third limb

for stability thanks to its closer

proximity to the ground compared to the

t-rex but which of these creatures would

be intelligent enough to figure out

these stabilizing intricacies

intelligence

one thing to note is that intelligence

is a very difficult thing to figure out

for animals especially extinct creatures

the best methods of studying this is

with brain scans and analyses of their

sensorial organs that would have been

there there has not been enough research

to properly determine the intelligent

quotients of spinosaurus the closest we

are to understanding its brain

capability is a study done on the

neuroanatomy of irritator challengeri a

relative of the spinosaurus research

shows that this animal's nervous system

was adapted for picking up low frequency

sounds and special vertical head

movements to sense and catch prey that's

all we know about the close relative of

the spinosaurus but given that the spino

is armed with similar weaponry we can

assume that this creature had to

understand how to use these effectively

and with purpose

the t-rex is another story there are

many studies done on determining the

intelligence of this animal many which

find that the olfactory organs of the

t-rex were disproportionately enlarged

another finding is that these creatures

had binocular vision capable of seeing

almost four times better than the

average human and being able to see

clearly for up to six kilometers to

understand its thinking process is

better the t-rex was measured at 1.0 in

the encephalization quotient which is

the same as a crocodile but more recent

scans have bumped this creature up to a

2.0 to 2.4 score which is better than

rodents canines and some felines and

only a tenth of a point short of a

chimpanzee suggesting that the t-rex

indeed had complex problem-solving

capabilities and was a very analytical

creature capable of determining

strengths and weaknesses to far greater

levels than ever imagined the only

things left to discuss are their weapons

bite effectiveness

it may come as a surprise to you but

both of these animals had bites that

could inflict some serious damage to

each other depending on a few factors

bite force as we know it can vary

greatly on the number of teeth surface

areas of the bite musculature and width

of the jaw every bite is different the

teeth of a tyrannosaurus rex are widely

known for their pickaxe shape and small

serrated edges this combined with its

wide jaw and strong neck muscles give

the t-rex a bite force of about eight to

ten thousand pounds per square inch

previously we have seen larger estimates

such as 12 800 psi but truth is that it

really just depends where exactly you

measure it if all of this force is

exerted on just one tooth for example

this could reach up to 431 342 psi a

bite from a tyrannosaurus rex would most

likely be inflicted using these areas of

its jaw giving us this figure ranking it

at the top of all theropod bite forces

this bite was so strong that it could

crush flesh and bone alike with ease and

go as far as possibly eating these bones

as well

the spinosaurus on the other hand had a

narrower jaw but this does not

necessarily mean that its bite was at

all weak again as mentioned earlier the

amount of teeth and shape greatly affect

the amount of pressure exerted on a

victim in the spinosaurus case its bite

force pressure would best be

concentrated in these areas these teeth

were best fit for biting down and

gripping which was useful when hunting

for prey underwater but exactly how

strong was this bite there is no study

that gives us an exact number but here's

what is known a study held in 2013

indicated that this skull was resistant

to torque and tension stresses with

vertical movements meaning that this

skull was well adapted for inflicting

strong bites in 2005 the bite force of

many theropods were studied including

sucomimus a distant relative after using

mathematical scaling it is reasonable

for some parts of the spinosaurus's jaw

to exert anywhere between

4250 to 5200 psi ranking its fight force

among theropods higher than originally

thought of course if we compare both

bite forces the tyrannosaurus rex still

far surpasses the strength of the spino

but in order to cause severe damage it

is not necessary to reach these levels

to kill the opponent these jaws must be

able to clamp deep enough to cause

bleeding or tear through vital organs

the spinosaurus would now also rely on

an additional set of weapons

auxiliary weaponry

now let's cover the last set of weapons

that will be used in this battle both of

these animals bring two arms tipped with

sharp claws but greatly vary in size the

two-fingered arms of a t-rex have been

an interesting topic of debate for many

researchers given that these are

unproportional for its size but contrary

to what you may think these things were

not weak this bicep muscle alone would

be able to lift more than 400 pounds

each some believe that these were used

to hold on to mates assist when standing

or even to grapple prey the problem with

this third method is that in order to

use these in combat the t-rex would have

to stand too close to the spinosaurus in

order to use them making biting more

difficult and putting itself at risk and

in this particular battle scenario the

spino wouldn't sit motionless waiting

for the rex to get this close on the

contrary it would resort to using its

own arms

as noted by researchers these three

fingered arms were not as reduced as its

hind legs suggesting that these held a

critical role in this animal's everyday

life especially when hunting if observed

closely there are two large claws on

these hands one which measured almost

one foot in length other observations

conclude that these arm attachments are

similar to what is seen in modern day

bears animals with almost supernatural

swing forces meaning that these could

slash and pull back causing even more

damage but is this the limit we also

must factor in the centrifugal forces of

the swing the slight rotation of its

body and the body weight behind the

strike resulting in an enormous swing

impact at the end of the spinosaurus's

claws a firm impact to the body of any

opponent would reach forces of up to

half a ton to a full ton on a small

surface enough to daze or fracture the

head of a large theropod if hit

correctly and with a big claw to project

all this force into a smaller area this

could potentially be lethal

weaknesses

before we finish entering the data into

the battle simulator we must debunk a

few misconceptions associated with these

animals the t-rex as mentioned earlier

did have the ability to swim but

wouldn't have been able to deep dive

like the spinosaurus by comparing both

animals bone density the spino's femur

denseness indicates that this animal was

in fact much more dense than the rex was

in the water although the terrestrial

mass seems to favor the t-rex on land

it's a completely different scenario in

a watery arena

a misconception associated with the

spinosaurus is the myth that once this

creature breaks its long spines then it

would die immediately this does not

necessarily make sense since the spinal

cord is housed inside something called a

vertebral foramen the spine itself is an

attachment or an extension of the

vertebrae called a process any breakage

that would happen if the spinal rolled

over violently would happen along this

area of the spine far enough for aspino

to not get handicapped in a fight should

the t-rex decide to bite or knock down a

spinosaurus interestingly there has been

evidence found that suggests that these

can heal over time if they are injured

according to the data that we have

entered into the simulator and given the

types of creatures that will be opposing

each other there are two possible

scenarios that could occur in a

confrontation between the spinosaurus

and the t-rex keep in mind that this

confrontation would have never happened

in the real world since they lived in

different time periods and different

geographical locations because the

spinosaurus is also adapted for aquatic

mobility and sub-aqueous foraging it

would also make sense for a

confrontation to happen alongside a

riverbank or even in the water itself

with the t-rex approaching the riverbank

because it considers it as a source of

water and the spinosaurus as a source of

both water and food

we are now ready to fire this simulation

the tyrannosaurus rex brings a stalky

build armed with jaws that can crunch

through flesh and bone abnormally agile

capabilities and advanced

problem-solving skills the spinosaurus

enters the fight with a surprisingly

stable corporal build which is highly

maneuverable in an aquatic arena a firm

bite with a strong grip and two

extremely dangerous forearms capable of

delivering lethal blows to an opponent

we will now initialize the first

simulation

[Music]

[Music]

[Music]

[Music]

in this specific scenario the

tyrannosaurus rex pulls off a win

given that this was 100 a fully

terrestrial scenario the tyrannosaurus

rex held the edge when it came to ground

locomotion the next big factor in this

simulation is that this t-rex's

problem-solving played a critical role

in the victory of this dinosaur while

this t-rex is built in such a way that

it could withstand heavy damage the

spinosaurus was able to land more hits

in the initial part of this fight thanks

to its superior forearm range upon

already receiving heavy blows an

intelligent predator like the t-rex

would understand that getting rid of

this weapon would be critical if he were

to get out of this one alive which is

why this animal went for the arm and

with its immense bite force and strong

neck muscles the rex was able to

critically injure the spinosaurus while

trying to retreat to the safety of the

river the t-rex now knocks the

spinosaurus down on the opposite side of

its body against the side that is no

longer capable of holding itself and

with a definitive bite to the neck it

ends the spinosaurus

but what if this battle happened in the

water in this scenario the t-rex sees a

spinosaurus for the first time and has

no idea that this creature is more

dangerous in this aquatic medium

spinosaurus being the better swimmer

positions in a way that allows it to

injure the t-rex repeatedly seeing it is

outmaneuvered in the water a

tyrannosaurus rex would most likely want

to retreat to its preferred terrestrial

habitat weakened and injured the

tyrannosaurus rex would most likely lose

this fight given the density of the

spinosaurus another likely outcome would

be the spinosaurus's more dense body

aiding in sinking the t-rex in deeper

water where the t-rex would most likely

be completely out of its element and

consequently die

on land the t-rex will hold its crown as

the most powerful meat-eater of all time

thanks to its ability to leverage its

problem-solving skills and knowing how

to use its weapons effectively but even

the strongest can fail when placed out

of their element both of these creatures

are without a doubt marvels of the

natural world and although these

creatures never saw each other we know

for certain this would have been one of

the most epic clashes in the animal

kingdom ever seen in history
