SAICHANIA
Pronunciation: sye-CHAY-nee-ah 
Translation: Beautiful One
Also Known As:
Description: Herbivore, Quadrupedal
Order: Ornithischia
Suborder: Thyreophora
Infraorder: Ankylosauria
Family: Ankylosauridae
Height: 8 feet (2.4 meters)
Length: 23 feet (7 meters)
Weight:
Period: Late Cretaceous
|
|
Notes: Saichania's fossil remains were found in southern Mongolia
with much of its armor plating still in position. Best known of the
Asian ankylosaurs, Saichania had a bony club on the end of its tail.
Its neck, back, and stomach were covered by rows of spikes and
knobs on bony plates.

SALTASAURUS
Pronunciation: salt-uh-SAWR-us
Translation: Salta Lizard
Also Known As:
Description: Herbivore, Quadrupedal
Order: Saurischia
Suborder: Sauropodomorpha
Infraorder: Sauropoda
Family: Titanosauridae
Height: 16 feet (4.9 meters)
Length: 40 feet (12.2 meters)
Weight:
Period: Late Cretaceous
|
|
Notes: The first sauropod known to be armored, Saltasaurus
was found in Argentina. Its broad back and sides were guarded
by small bony studs and several bony plates.
|

SALTOPUS
Pronunciation: sal-TOH-pus
Translation: Leaping Foot
Also Known As:
Description: Carnivore, Bipedal
Order: Saurischia
Suborder: Theropoda
Family:
Height: 12 inches (0.3 meters)
Length: 24 inches (0.6 meters)
Weight: 2 pounds (0.9 kg)
Period: Late Triassic
|
|
Notes: Found in Scotland, Saltopus may be the oldest European
dinosaur. Similar in build to Procompsognathus but much smaller
and lighter, it was not as tall as a domestic cat and weighed as little
as two pounds. This tiny predator snatched prey with five-fingered
hands - a primitive feature, although the fourth and fifth fingers were
tiny. Its hip/backbone arrangement was more advanced than
Procompsognathus and formed a fairly solid anchor for the long
running legs.

Also Known As:
Description: Herbivore, Quadrupedal
Order: Ornithischia
Suborder: Thyreophora
Infraorder: Ankylosauria
Family: Nodosauridae
Height: 6 feet (1.8 meters)
Length: 18 feet (5.5 meters)
Weight:
Period: Middle Jurassic
|
|
Notes: Found in England, Sarcolestes is the oldest known armored
dinosaur, protected by bony plates, slabs, and spikes. The logic
behind Sarcolestes' misleading name is unknown.

SARCOSAURUS
Pronunciation: SAR-ko-SAWR-us
Translation: Flesh Lizard
Also Known As:
Description: Carnivore, Bipedal
Order: Saurischia

two-legged predator was discovered in England.

SAUROLOPHUS
Pronunciation: SAWR-OL-o-fus
Translation: Crested (or Ridged) Lizard
Also Known As:
Description: Herbivore, Bipedal
Order: Ornithischia
Suborder: Ornithopoda
Infraorder: Iguanodontia
Family: Hadrosauridae
Height: 17 feet (5.2 meters)
Length: 31.8 feet (9.7 meters)
Weight:
Period: Late Cretaceous
|
|
Notes: Found in North America and China, this duck-billed
dinosaur had a bony spike projecting from the back of its head.
Saurolophus is well-known from very complete remains, including
skin casts.

SAUROPELTA
Pronunciation: SAWR-oh-PEL-tah
Translation: Lizard Shield
Also Known As:
Description: Herbivore, Quadrupedal
Order: Ornithischia
Suborder: Thyreophora
Infraorder: Ankylosauria
Family: Nodosauridae
Height: 8 feet (2.4 meters)
Length: 24 feet (7.3 meters)
Weight: 6,000 pounds (2,720 kg)
Period: Early Cretaceous
|
|
Notes: Sauropelta was one of the earliest known nodosaurs from
North America. It is the one of the most numerous members of the
nodosaur family of ankylosaurs, many specimens having been
recovered.

SAUROPLITES
Pronunciation: SAWR-uh-PLY-teez
Translation: Stone-like Lizard, or Lizard Hoplite
Also Known As:
Description: Herbivore, Quadrupedal
Order: Ornithischia
Suborder: Thyreophora
Infraorder: Ankylosauria
Family:
Height: 6 feet (1.6 meters)
Length: 18 feet (5.5 meters)
Weight:
Period: Early Cretaceous
|
|
Notes: Discovered in China and Mongolia, Sauroplites is one
of the oldest known ankylosaurids. (Tianchisaurus from the
Middle Jurassic is currently the earliest ankylosaurid.)

SAURORNITHOIDES
Pronunciation: SAWR-or-nih-THOY-deez
Translation: Bird-like Lizard
Also Known As:
Description: Carnivore, Bipedal
Order: Saurischia
Suborder: Theropoda
Infraorder: Tetanurae
Micro-order: Maniraptora (of the microorder Coelurosauria)
Family: Troödontidae (not confirmed)
Height: 3 feet (0.9 meters)
Length: 6.5 feet (2 meters)
Weight: 120 pounds (54.4 kg)
Period: Late Cretaceous
|
|
Notes: Found in Mongolia, Saurornithoides was one of the most
intelligent dinosaurs based upon its brain-weight to body-weight ratio.
The fact that its eyes are situated pointing forward hints that, like
many modern animals, Saurornithoides may have had stereoscopic
vision, a characteristic that would have helped it to judge distance.
Saurornithoides is very similar in many ways to Troödon, which
lived in Western North America during the Cretaceous Period.

SAURORNITHOLESTES

blade-like second-toe claw.

is one of the earliest known thyreophorans. It was an armored
dinosaur thought by some to be capable of making brief runs on
its two hind feet.
