dinosaurs

are

traditionally

believed

to

be

cold-blooded

reptiles,

suchas

crocodiles,

lizards

and

sea

turtles,

evidences

recently

discovered

have

implieda

pictureon

quite

the

opposite

side.

Scientiststoday

are

more

ready

to

believethat

there

is

a

good

chance

for

dinosaurs

to

bewarm-blooded

animals,

liketoday’s

mammals

and

birds.First,

as

demonstrated

by

a

stony

heart

recently

found

in

South

Dakota

in

1993by

a

private

fossil

collector,

dinosaurs

could

have

evolved

a

heart

adaptedtowarm-blooded

circulation.Although

the

fact

that

soft

tissues

usually

posedbefore

they

could

fossilize

had

left

scientistssearching

in

darkness

for

centuries,fossil

organs

could

still

be

preserved

under

extreme

circumstances

such

as

rapidsediment

on

the

seabed.

Becausetoday

four-chambered

heart

is

only

foundinwarm-blooded

animals,

this

fossilheartindicates

thecloserelationshipbetween

dinosaurs

and

mammals.Second,

because

cold-blooded

animals

such

as

reptiles

couldn’t

maintain

theirbody

temperature

constantly,

they

have

to

rely

on

the

surrounding

environmentto

adjust

the

body

heat.

Thus,

if

dinosaurs

arecold-blooded,

theirhuge

bodysize

would

makeit

impossible

to

shift

between

basking

and

burrowing

asoftenas

today’s

lizards.Third,

for

huge

body

animals

to

maximize

their

energy

usage,

theymustmaintain

a

constant

body

temperature.

This

is
