This small plant-eaterwas one of the
first dinosaurs to be discovered in
NorthAmerica.
‘ bout 210 million years ago,in the Early Jurassic Period,herds ofAnchisaurus plodded
across the lake shores insearch of food.
They were some of the earliest plant-
eating dinosaurs on Earth.These peaceful
grazers probably feasted on the earlyhorsetails and ferns that flourished bythe edge of the water.
UP AND DOWNAnchisaurus hada front-heavy body—o it
probably walked on all-fours as well as on
two legs. The dinosaur may have rearedup on its hind legs to reach the plant tops.It probably used its short front legs to
steady its long, heavybodywhen it was on
the move.Anchisauruswould have held its
large thumb claws offthe ground to stopthem getting damaged.
~o-»%;>.s.“
ANCIENT SAUROPOD
The long-neckedAnchisauruswas a
prosauropod—primitive version of the
giant sauropods such as Brachiosaurus,
which lived millions ofyears later.
TIP TOPAnchisaurus was one of the first dinosaurs
to be able to crane its neck upwards to find
more food. Other plant-eaters living at thesame time were short, stocky creatures
with short necks. Theywere unable to
reachthe tender green shoots that grew
higher up. ButAnchisaurus could alwaysfind plenty ofjuicy leaves to eat.
SHARP TEETH
Anchisaurus had saw-edged, pencil-shapedteeth. It used them to shred the
leafytwigs
and ferns it fed on. The dinosaur probablystuffed the plant pieces into its mouthwith its hands, so that nothingfell outwhile it was eating.

BANDAIDFossil footprints show thatAnchisaurusmoved about in herds.They probablybanded together for protection.Bigmeat-
eaters,'such as Dilophosaurus, Were less
likely to attack a largegroup ofanimals,and twenty pairs ofeyes were better than
one for spottingpotentialpredators.
ON THE RUN
Anchisauruswas as long as a man is tall,but lighter. It was probably fairly fast on
its feet andmight have outrun a hungrycarnivore. If the plant-eaterwas cornered,it couldhave struck outwith its greatcurved"thumb claws to defend itself.
Anchisaurus was probablyAmerica's first
knowndinosaur. But itwas notcorrectly
identifiedfor about 100years. The firstfossilwas found in l8l 8, but itwas
thought tobepartofa human skeleton.
Itwasn't until l855 that experts realised
itwas partofan animal. Itwas then
reclassified as a dinosaur. Itwas finallyidentifiedas Anchisaurus in W12.

TALL FEEDERS
Here and there, on the wooded river
banks, you can see herds ofDiplodocus.
They rise up on their hind legs, reachingtheir longnecks highup into the trees to
eat. The trees are bare ofbranches up to
the highest point the sauropods can reach.
Occasionally,you catch glimpses of other
sauropods, such as Brachiosaurus.Camarasaurus lives here too.
HERE COMES THE RAIN
As you continue your journey, the wet
season begins and the rains fall. Ferns
springupin the open areas between the
streams. The cycads put out new bunchesofpalm-like fronds on top of their barrel-
shaped trunks. The sauropods are still on
the move, enjoying the fresh vegetation.And you can see many other animals out
looking for food.
The scene below shows the sort of
countrysidethat
youwill be
journeyingthrough after the rains fall. Remember to
keep an eye out for the meat-eaters!
Stegosrus
A BEAST OFOPEN COUNTRY
In the distant open spaces, you see the
jagged silhouette of a Stegosaurus. This
platedplant-eater prefers the drier open
spaces. Out in the open, its plates will not
become entangled in branches, andtheWind can keep itsmassive body cool.
SMALLER CREATURES
Pterosaurs sweep down, screeching over
your head. They probably think you are a
small, but dangerous, meat—eatingdinosaur. There are somedinosaurs livinghere that are just your size. Swift andferocious Ornitholestes and Coelurus, for
instance.Watch out for them! These two-legged predators can run very fast, andcan catch their victims in long, clawed
fingers and sharp teeth.
TOTHE HILLS
After many days’ travel you see themountains ahead, and you start to climbinto the foothills. The scenery changes
completely.Now you are walking up
wooded hillsides. Great tree ferns, coveredwith creepers, tower above you.
7/30/2019 Dinosaurs 81
http://slidepdf.com/reader/full/dinosaurs-81 11/28
HIDDENANIMALSAnimal life is different here, too,but youcannot really see it. It is hidden in the
thick undergrowth. Some plants havethorns more than 2cm long. They probably
protect the plants against bigbrowsinganimals!More than once, however, youcome across a great armoured ankylosaur
feeding in a clearing. It is difficult to saywhat kind it is, but it is quite primitive.
OVER THE MOUNTAIN...At last you come to themountains.
Pterosaurs soar around the peaks, but,
apartfrom them, there is very little
animal life. Slowly;-youmake, your waythrough”the-mountain passes‘.57’Then you
begin to descend towards the-ocean.
...AND DOWN TOTHE SEA
Again, you pass throughwooded foothills.
But now, through the leaves, you catch a
glimpse ofwater ahead ofyou. You caneven see a string of islands, with smokingvolcanoes. This is where the
edgeof the
continent is beingcrushed andpushed upto form mountains.

during the Jurassic?ln recent years, ankylosaur fossils have
been "found in the Morrison’Formation,
which is made up of layers of rock stretchingalong the foothills ofthe Rockies, fromMontana to
New‘Mexico. The muds,‘sands and gravels whichformed these rocks were laid down by streams
running across a plain in Late Jurassic times. Some
of the bestzdinosaursfiskeletons have been found
here. The ankylosaur fossils were not very well
preserved and scientists think they were washeddown from the uplands, where these beasts lived.

cliffs, plesiosaurs and icthyosaurs swim in

Prehistoric
scavengersWhen a dinosaur died, its bodywas
not just left to rot. There were plentyof creatures more than happy to take
advantage of an easymeal.
nimals in the Wild die forr many reasons. Some arekilledby predators, others die of
old age or illness.But their bodies do not
stay around for long. A dead animal
provides a tastymeal for an entire army of
scavengers, from large mammals to tinybacteria. Scavengers are nature’s refuse
collectors, clearingaway unwantedrubbish. Without them, the world wouldbe litteredwith rottingcarcasses.
FOOD NOT FOSSILS
Why are most fossils the remains ofplantsand animals thatwere buried soon after
they died? One reason is that scavengers
quickly remove anything left out in the
open. Only in very coldor very dry places doanimal remains stay untouched.
LAZY HUNTERSThe biggest scavengers today are flesh-
eaters, such as hyenas andjackals.Although these creatures canhunt for
themselves, they also prowlaround otheranimals that have madekills,waiting
moving in for theleftovers.
..,,,,. ,
IN FORTHE KILLIt was probably thesame in the days of thedinosaurs. In the Late
Cretaceous, packs offierce Dromaeosaurus hunted large

relatively small dinosaur, but it was

Although
hyenas are
good hunters,
they will often
feed on lions’
kills once thelions have
eaten their fill.
MOVE OVER!
Often, larger, slower-moving carnivores,such as mighty Tyrannosaurus rex, were
attracted by the stench ofblood in the air.
They followed the scent to the scene of'
the kill, and lurkednearby, Waitingto steal the meal.When the preyWas dead, or almost so, T rex would
move in. The smaller dinosaurswere driven offand the giantwas
left to eat his fill.
OUR MEAL TOO!
But the pack ofDromaeosaurus
didnot give up that easily!
Theywaited nearby, andsnatchedmouthfuls of food
while T rex was busy eating.
,_And,when the giant had7 finished feeding, there was still
plenty left forDromaeosaurusand
other smaller creatures.
Packs of Dromaeosauruswere fierce hunters.They were
able to kill large prey, such as Triceratops. But larger
predators,such as Tyrannosaurus rex,were able to bullytheir way through and steal their kills. Smaller scavengers,such
as rodentsand
bugs,also came to feed.

COULD NOT CRUSH BONES.
The teeth ofcarnivorous dinosaurs were
designed for slashing and carving.
They did nothave strong enough teeth
or jaws tocrush bones. The bones ofaCamarasaurus fromWyoming, in the
USA,have been foundwith large,grooved toothmarks, cut soon atter thecreature died. But none ofthe bones

MUMMIFIED
Not all dinosaur carcasses were eaten inthis Way.Severalmummified dinosaurshave been unearthed. This happenswhenthe body,with skin and flesh intact, dried
out completely before being fossilized. Thismeans that scavengers hadnot beenableto strip all themeat and bones from thedead dinosaur. Perhaps these preserveddinosaurs died in an area where
scavenging dinosaurs and animals couldnot reach them. Or perhaps, millions of
years ago, there were fewer scavengers atwork than there are today.
Not all dinosaur carcasses were picked clean by
scavengers. Sometimes the bodies dried outbefore becoming fossils. This means experts can
study fossils of flesh and skin, such as this
Eclmontosaurus skin (above), as well as bones.
