TALARURUS
Pronunciation: tah-lah-ROO-rus 
Translation: Basket-Tailed
Also Known As:
Description: Herbivore, Quadrupedal
Order: Ornithischia
Suborder: Thyreophora
Infraorder: Ankylosauria
Family: Ankylosauridae
Height: 6 feet (1.8 meters)
Length: 16.4 feet (5 meters)
Weight:
Period: Late Cretaceous
|
|
Notes: Talarurus was found in Mongolia. Bands of thick bony
plates guarded its hips, back, and tail, and it had a bony tail club
with which it could swat an attacker.

TANIUS
Pronunciation: TAN-ee-us
Translation: of the Tan
Also Known As: Tsintaosaurus
Description: Herbivore, Bipedal
Order: Ornithischia
Suborder: Ornithopoda
Infraorder: Iguanodontia
Family: Hadrosauridae
Height: 20 feet (6.1 meters)
Length: 35 feet (10.7 meters)
Weight: 6,000 pounds (2,722 kg)
Period: Late Cretaceous
|
|
Notes: Tanius was a large, flat-headed duck-billed dinosaur
that lived in China in the late Cretaceous, some 88 to 66 million
years ago. As the specimens found to date show no evidence
of a crest, Tanius may have belonged to the crestless basal
hadrosaurine group of duckbills. Another theory holds that
Tanius will turn out to be the same animal as Tsintaosaurus,
a familiar duckbill pictured in many books because of its
unicorn-like spike.

Pronunciation: ta-RASS-co-SAWR-us
Translation: Tarascan Lizard
Also Known As:
Description: Carnivore, Bipedal
Order: Saurischia
Suborder: Theropoda
Infraorder: Ceratosauria
Family: Abelisauridae
Height:

Weight:
Period: Late Cretaceous

Notes: Tarascosaurus is known from fragmentary remains. A few
vertebrae, teeth, and a femur have been discovered in the South
of France.

TARCHIA
Pronunciation: TAR-kee-a
Translation: Brainy
Also Known As:
Description: Herbivore, Quadrupedal
Order: Ornithischia
Suborder: Thyreophora
Infraorder: Ankylosauria
Family: Ankylosauridae
Height: 8 feet (2.4 meters)
Length: 20 feet (6.1 meters)
Weight: 5,700 pounds (2,586 kg)
Period: Late Cretaceous
|
|
Notes: Discovered in southern Mongolia, Tarchia is the largest
and the geologically most recent of the Mongolian armored
dinosaurs. These dinosaurs were distinguished by the large spikes
on their sides and their clubbed tails. Tarchia had a high skull,
spikes at the corner of its mouth and a particularly large tail club.
Tarchia, meaning brain, was so named because its skull, which is
about the same size as Saichania, has a much larger braincase.

TECHNOSAURUS
Pronunciation: TEK-no-SAWR-us
Translation: (Texas)Tech (University) Lizard
Also Known As:
Description: Herbivore, Quadrupedal
Order: Ornithischia
Suborder: Not known
Infraorder: Not known
Family: Not known
Height:
Length:
Weight:
Period: Late Triassic
|
|
Notes: Technosaurus was discovered near Lubbock, Texas.
The remains found were from the lower jaw, an upper jaw fragment,
and other lower bones. The dinosaur has been classified as an
Ornithischian, but may be an early prosauropod.

TELMATOSAURUS
Pronunciation: tel-MAT-o-SAWR-us
Translation: Marsh Lizard
Also Known As:
Description: Herbivore, Bipedal
Order: Ornithischia
Suborder: Ornithopoda
Infraorder: Iguanodontia
Family: Hadrosauridae
Height: 6.5 feet (2 meters)
Length: 16.4 feet (5.0 meters)
Weight:
Period: Late Cretaceous
|
|
Notes: Found in Hungary, Telmatosaurus is the only positively-
known European representative of the duck-billed dinosaurs.

TENONTOSAURUS
Pronunciation: teh-NON-tuh-SAWR-us
Translation: Sinew Lizard
Also Known As:
Description: Herbivore, Bipedal, semi Quadrupedal
Order: Ornithischia
Suborder: Ornithopoda
Family:
Height: 13 feet (4 meters)
Length: 23 feet (7.0 meters)
Weight: 4,000 pounds (1,814 kg)
Period: Early Cretaceous
|
|
Notes: Found in the western and southwestern United States,
Tenontosaurus was a large plant-eater that resembled Iguanodon.
Its tail was stiffened by ossified tendons that reinforced the tail
vertebrae providing balance for its bipedal stance. Like some other
ornithopods, Tenontosaurus probably dropped to all fours when
browsing. Because the teeth of Deinonychus have been found in
the vicinity of Tenontosaurus remains, it is thought that Tenontosaurus
might have been Deinonychus' prey.

THECODONTOSAURUS
Pronunciation: thee-kuh-DON-tuh-SAWR-us
Translation: Socket-toothed lizard
Also Known As: Agrosaurus
Description: Herbivore, Bipedal
Order: Saurischia
Suborder: Sauropodomorpha
Infraorder: Prosauropoda
Family: Thecodontosauridae
Height: 4 feet (1.2 meters)
Length: 9.6 feet (3 meters)
Weight:
Period: Late Triassic
|
|
Notes: A very primitive prosauropod, Thecodontosaurus was
found in England. Similar fossils have been found in North America,
Africa and Australia. Thecodontosaurus had a long neck and
slender limbs.

THERIZINOSAURUS
Pronunciation: thair-uh-ZEEN-uh-SAWR-us
Translation: Scythe Lizard
Also Known As:
Description: Herbivore, Bipedal?
Order: Saurischia
Suborder: Theropoda
Family: Therizinosauridae
Height: 15 feet (4.6 meters)
Length: 36 feet (11 meters)
Weight: Period: Late Cretaceous
|
|
Notes: Fragmentary remains of Therizinosaurus were discovered
in southern Mongolia. A late Cretaceous dinosaur, its skeletal
structure (other than an arm) remains a mystery. This dinosaur
had sickle-shaped claws over 2 feet (0.6 meters) long. It may
have used this formidable weapon for attacking and butchering
its prey, or digging up huge ant nests.
