EUCENTROSAURUS
Pronunciation: you-SEN-truh-SAWR-us 
Translation: Sharp Pointed Lizard
Also known as: Centrosaurus
Description: Herbivore, Quadrupedal
Order: Ornithischia
Suborder: Marginocephalia
Infraorder: Ceratopsia
Micro-order Neoceratopsia
Family: Ceratopsidae
Height: 8 feet (2.4 meters)
Length: 16.4 feet (5 meters)
Weight:
Period: Late Cretaceous
|
|
Notes: Discovered in large numbers in Alberta, Canada,
Eucentrosaurus is one of the best-known ceratopsians.
Apparently a herd of these dinosaurs died all at once,
perhaps caught in a flash flood. Smaller than Triceratops,
Eucentrosaurus had a forward-curving 18-inch (46-cm)
nasal horn and a pair of small horns above its eyes. Skin casts
exist that show Eucentrosaurus to possess a knobby skin with
hexagonal or pentagonal bumps set close together.

EUHELOPUS
Pronunciation: you-heh-LO-pus
Translation: Good Marsh Foot
Also known as: Helopus
Description: Herbivore, Quadrupedal
Order: Saurischia
Suborder: Sauropodomorpha
Infraorder: Sauropoda
Family: Euhelopodidae
Height: 14 feet (4.3 meters)
Length: 34 feet (10 meters)
Weight: Up to 50,000 pounds (22,680 kg)
Period: Late Jurassic
|
|
Notes: Partial skeletons of this extremely long-necked saurischian
were found in China. With forelimbs as long as its hind limbs,
Euhelopus was unusual-looking for a camarasaurid, which was
its original family classification. Further studies have determined
that members of this genus, as well as other Chinese sauropods
from this time, such as Mamenchisaurus, share enough unique
characteristics to constitute a separate sauropod family. The new
sauropod family has logically been named Euhelopodidae.

EUOPLOCEPHALUS
Pronunciation: you-op-luh-SEF-uh-lus
Translation: Well-protected Head
Also known as: Dyoplosaurus,
Anodontosaurus, Scolosaurus
Description: Herbivore, Quadrupedal
Order: Ornithischia
Suborder: Thyreophora
Infraorder: Ankylosauria
Family: Ankylosauridae
Height: 6 feet (1.8 meters)
Length: 20 feet (6.1 meters)
Weight: 3,970 - 7,050 pounds (1,800-3,175 kg)
Period: Late Cretaceous
|
|
Notes: Discovered in Alberta, Canada, Euoplocephalus is one
of the best-known armored dinosaurs. The upper part of its body,
including its eyelids, was covered with bony plates and rows of
horny spikes up to six inches (15 cm) long. Built low to the ground
with massive, short leg bones, this "armored tank" had a distinctive
clubbed tail. The many Euoplocephalus skeletons recovered have
all been found isolated from one another, leading to the picture of
this dinosaur as a solitary grazer.

EUSKELOSAURUS
Pronunciation: yoo-SKEL-uh-SAWR-us
Translation: Good Leg Lizard
Also known as:
Description: Herbivore, Quadrupedal,
semi Bipedal
Order: Saurischia
Suborder: Sauropodomorpha
Infraorder: Prosauropoda
Family: Plateosauridae
Height: 10 feet (3 meters)
Length: 29.5 feet (9 meters)
Weight:
Period: Late Triassic
|
|
Notes: Euskelosaurus was plentiful in its day. It had a long neck
and tail and, like all prosauropods, was able to walk on its hind legs.

EUSTREPTOSPONDYLUS
Pronunciation: you-strep-tuh-SPON-dih-lus
Translation: Well-Reversed Vertebrae
Also known as: Streptospondylus
Description: Carnivore, Bipedal
Order: Saurischia
Suborder: Theropoda Infraorder: Tetanurae
Micro-order: Carnosauria
Family: Eustreptospondylidae
Height: 10 feet (3.0 meters)
Length: 23 feet (7.0 meters)
Weight: 2,500 pounds (1,134 kg)
Period: Middle Jurassic
|
|
Notes: The remains of Eustreptospondylus were among the first
to be named by Sir Richard Owen in 1841, one year before he
published the term dinosaur for the first time. The skeleton of this
carnivore is on display at the University Museum in Oxford. It
resembles Meglosaurus, the first dinosaur to be named (1824).
Eustreptospondylus was related to Allosaurus which appeared
in the Late Jurassic. Its head was large, and its long jaws were
lined with sharp, serrated teeth.
