Brontosaurus
Oops!
This is actually a Apatosaurus. It was
mistakenly named in the 1870's. Now most
museums do not use the name "brontosaurus".
Apatosaurus means "deceptive
lizard"
It was about 18 m long and
weighed about 30 tons.
It had a very small brain.
Herbivore
Diplodocus
Diplodocus is a plant eater.
It has a long neck and a
very long tail.
The Diplodocus is one of
the longest land animals.
The Diplodocus walked on
all four legs.
Herbivore
Brachiosaurus
This was one of the largest
dinosaurs.
It was 25m long (81 feet)
and weighed about 80 tons
(160,000 pounds).

It walked on its back legs, weighed about 7 tons (14,000 pounds) and
was about 30 feet long.
The Iguanodon had human like hands with a sharp thumb, he used as
a weapon.
Herbivore
Trachodon
Trachodon (meaning "rough tooth") is a plant-eating dinosaur that is
known only from a few teeth and jaw parts that were found in
Montana, USA. From the teeth, it has been surmised that Trachodon
was probably a duck-billed dinosaur (a lambeosaurine hadrosaur).
Trachodon dates from the late Cretaceous period, about 77-73 million
years ago.
Herbivore
Trachodon is a dubious genus due to the sparsity of fossils.
Triceratops

to fight their predators. Their heads were huge and
about 1/3 as long as their bodies.

bird-like head compared to the
rest of its huge body.
Its brain was about the size of a
walnut. Its back legs were

plates down its back and
tail. He used his tail as a
weapon.

tail.
Ankylosaurus was about 18-20 feet long and six foot high.

This horned-faced
dinosaur laid eggs in a
sandy nest near a pond.
This dinosaur was usually
part of a herd that helped
protect each other.
Its sharp beak was its main
defense against predators.
Herbivore
Fossilized Eggs
Allosaurus eggs have
been found which would
have contained tiny
Allosaurus means "different lizard," named
embryos
for its unusual vertebrae, lighter than those of
other dinosaurs
Allosaurus was a top predator with a huge head,
sharp, serrated teeth, short arms, and threefingered hands.

dinosaurs.

walked upright.
He was about 20 feet high and 40 feet long.

teeth.
Carnivore
Elasmosaurus
Elasmosaurus was a long-necked
marine reptile that was up to 46 feet
long (14 m).
Half of its length was its neck, which
had as many as 75-76 vertebrae in it (in
comparison, people have 7-8 neck
vertebrae).
