ECHINODON
Pronunciation: eck-EYE-nuh-don 
Translation: Spiny Tooth
Also known as: Saurechinodon
Description: Herbivore, Quadrupedal
Order: Ornithischia
Suborder: Thyreophora?
Family: Scelidosauridae?
Height: 1 foot (0.3 meters)
Length: 2 feet (0.6 meters)
Weight:
Period: Late Jurassic
|
|
Notes: Discovered in England and described by Sir Richard
Owen in 1861, Echinodon was once considered to be a
fabrosaurid, a family name that has now been abandoned.
It may have been related to Scutellosaurus, a plant-eater with
small bony armor plates on its back. Evidence suggests that
armor found in England in 1879 and thought to belong to a lizard,
may belong to Echinodon, thus moving it into the mostly
quadrupedal Thyreophora suborder of ornithischians.

EDMONTOSAURUS
Pronunciation: ed-MON-tuh-SAWR-us
Translation: Edmonton Lizard
Also known as: Anatosaurus, Thespesius
Description: Herbivore, Bipedal
Order: Ornithischia
Suborder: Ornithopoda
Infraorder: Iguanodontia
Family: Hadrosauridae
Height: 20 feet (6.1 meters)
Length: 43 feet (13.1 meters)
Weight: 7,000 - 8,000 pounds (3,175-3,630 kg)
Period: Late Cretaceous
|
|
Notes: Edmontosaurus was discovered in Alberta, Canada.
A plant eater with batteries of teeth in its jaw bone for pulverizing
plant food, it had up to 60 rows of teeth on each jaw -- more
than 1,000 teeth in total.

ELAPHROSAURUS
Pronunciation: ee-LAFF-ruh-SAWR-us
Translation: Lightweight Lizard
Also known as:
Description: Carnivore,Bipedal
Order: Saurischia
Suborder: Theropoda
Infraorder: Tetanurae
Superfamily: Ornithomimosauria
(of the microorder Coelurosauria)
Family: Ornithomimidae
Height: 6.5 feet (2 meters)
Length: 11 feet (3.4 meters)
Weight:
Period: Late Jurassic
|
|
Notes: Elaphrosaurus was discovered in Africa and North America.
One of the earliest members of the ornithomimid family, it was a very
lightweight, fast predator. Its hands and feet each had three digits.

ELMISAURUS
Pronunciation: EL-mih-SAWR-us
Translation: Foot Lizard
Also known as:
Description: Carnivore, Bipedal
Order: Saurischia
Suborder: Theropoda
Infraorder: Tetanurae
Micro-order: Maniraptora
(of the microorder Coelurosauria)
Family: Elmisauridae
Height: 3.3 feet (1 meter)
Length: 6.6 feet (2 meters)
Weight:
Period: Late Cretaceous
|
|
Notes: The identification of Elmisaurus is based upon the discovery
of a single, distinctive foot. There are similarities between this foot
and those of other theropods, but the differences indicate that it is
in a class of its own.

EMAUSAURUS
Pronunciation: ee-mau-SAWR-us
Translation: Named after
Ernst-Moritz-Arndt-Universitat
Also known as:
Description: Herbivore, Quadrupedal
Order: Ornithischia
Suborder: Thyreophora
Family: Scelidosauridae
Height: 2 feet (0.6 meters)
Length: 6 feet (1.8 meters)
Weight: 500 pounds (227 kg)
Period: Early Jurassic
|
|
Notes: A nearly complete skull was discovered in Germany.
This small dinosaur is related to Scutellosaurus and
Scelidosaurus. It had a narrow snout and palate.
|
|
ENIGMOSAURUS
Pronunciation: e-NIG-ma-SAWR-us
Translation: Mysterious Lizard
Also known as:
Description: Herbivore, Bipedal?
Order: Saurischia
Suborder: Theropoda
Infraorder:
Family: Therizinosauridae
Height: 10 feet (3 meters)
Length: 23 feet (7 meters)
Weight:
Period: Late Cretaceous
|
|
Notes: As its name suggests, Enigmosaurus is known only
from the fragmentary remains of its pelvis. Though classified as
a saurischian, this dinosaur had a peculiar reverted pubis seen
in the dromaeosaurids, but they are not closely related to
that group.

EOCERATOPS
Pronunciation: ee-o-SAIR-uh-tops
Translation: Dawn Horned Face
Also known as:
Description: Herbivore, Quadrupedal
Order: Ornithischia
Suborder: Marginocephalia
Infraorder: Ceratopsia
Micro-order Neoceratopsia
Family: Ceratopsidae
Height: 7 feet (2.1 meters)
Length: 18 feet (5.5 meters)
Weight:
Period: Late Cretaceous
|
|
Notes: Eoceratops was discovered in Alberta, Canada. Although
it is obviously a ceratopsian, its skull is barely 3 feet (0.9 meters) long.
It may be that Eoceratops is actually a young Chasmosaurus.

EORAPTOR
Pronunciation: ee-oh-RAP-tor
Translation: Dawn Plunderer
Also known as:
Description: Carnivore, Bipedaly
Order: Saurischia
Suborder: Theropoda
Family:
Height: 20 inches (0.5 meters)
Length: 36 inches (0.9 meters)
Weight: 8 pounds (3.6 kg)
Period: Late Triassic
|
|
Notes: Discovered in Argentina in 1991 by a team led by Paul
Sereno of the University of Chicago, Eoraptor is the most primitive
dinosaur known -- 228 million years old. This find, coupled with
the discoveries of Staurikosaurus and Herrerasaurus in South
America, has led some scientists to suspect that the region is
the cradle of Dinosauria.

ERECTOPUS
Pronunciation: ee-REK-tuh-pus
Translation: Upright Foot
Also known as:
Description: Carnivore,Bipedal
Order: Saurischia
Suborder: Theropoda
Infraorder: Ceratosauria
Family: Megalosauridae
Height:
Length:
Weight:
Period: Early Cretaceous
|
|
Notes: Fragmentary remains of Erectopus have been found
in northern France, Egypt, and Portugal. This name was given
because the animal apparently walked upright.

ERLIKOSAURUS
Pronunciation: er-LIK-uh-SAWR-us
Translation: Erlik's Lizard
Also known as:
Description: Herbivore, Bipedal?
Order: Saurischia
Suborder: Theropoda
Infraorder:
Family: Therizinosauridae
Height: 9 feet (2.7 meters)
Length: 16 feet (4.9 meters)
Weight: Period: Late Cretaceous
|
|
Notes: An unusual kind of dinosaur that lived in Mongolia, its name
is derived from the Lamaist deity Erlik. It had a long, slender,
toothless beak. However, further back in its mouth were rows of
tiny leaf-shaped teeth usually associated with herbivores like
Lesothosaurus and the prosauropods. Recent analysis indicates
that they are theropods but unlike most theropods, they have four
big toes on each foot instead of the typical three.
