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.
