VULCANODON
 
ULTRASAUROS
Pronunciation: UL-truh-SAWR-us  
Translation: Ultra Lizard
Also Known As:
Description: Herbivore, Quadrupedal
Order: Saurischia
Suborder: Sauropodomorpha
Infraorder: Sauropoda
Family: Brachiosauridae (not confirmed)
Height: 53 feet (16 meters)
Length: 100 feet (30.5 meters)
Weight: 140,000 pounds (63,504 kg)
Period: Late Jurassic


Notes: Discovered in Colorado by dinosaur digger Jim Jensen of Brigham Young University, this extremely large dinosaur was formerly known as Ultrasaurus. The name was changed as it had previously been claimed for a South Korean specimen. Ultrasauros had an unusually small head that towered on a giraffe-like neck, a short tail for its size, and pillar-like legs. In fact, Ultrasauros may have been a very large Brachiosaurus.


UTAHRAPTOR
Pronunciation: Yoo-tah-RAP-tor  
Translation: Utah Lizard
Also Known As:
Description: Carnivore,Bipedal
Order: Saurischia
Suborder: Theropoda
Infraorder: Tetanurae
Micro-order: Maniraptora (of the microorder Coelurosauria)
Family: Dromaeosauridae
Height: 9.8 feet (3 meters)
Length: 21.3 feet (6.5 meters)
Weight: 1,500 pounds (680 kg)
Period: Early Cretaceous




Notes: Found in eastern Utah, this dinosaur was armed with a 15-inch (35-cm) claw on one toe of each hind foot, claws on each finger of its hands, and razor-sharp teeth. Believed to be an agile, very fast predator, Utahraptor probably attacked prey many times larger than itself, striking numerous fatal blows with its sharp hind claws. It is also believed to have hunted in packs, thus indicating behavior of a relatively intelligent and warm-blooded animal. Utahraptor combines the behavior of Velociraptor and Deinonychus with much greater size.


VALDOSAURUS
Pronunciation: VAL-doe-SAWR-us  
Translation: Weald Lizard
Also Known As:
Description: Herbivore, Bipedal
Order: Ornithischia
Suborder: Ornithopoda
Infraorder: Iguanodontia
Family: Dryosauridae
Height: 5 feet (1.5 meters)
Length: 11 feet (3.4meters)
Weight: Period: Early Cretaceous


Notes: Closely related to and resembling Dryosaurus, Valdosaurus was probably a descendent of that dinosaur. Its remains have been found in England and Niger.


VECTISAURUS
Pronunciation: VEK-tuh-SAWR-us  
Translation: Spike Lizard, or Isle of Wight Lizard
Also Known As: Iguanodon
Description: Herbivore, Bipedaly
Order: Ornithischia
Suborder: Ornithopoda
Infraorder: Iguanodontia
Family: Iguanodontidae
Height: 5 feet (1.5 meters)
Length: 13.5 feet (4.1 meters)
Weight:
Period: Early Cretaceous


Notes: Found in Isle of Wight, England, Vectisaurus is similar to Iguanodon, although it had taller spines jutting from its backbone.


VELOCIRAPTOR
Pronunciation: veh-loss-ih-RAP-tor  
Translation: Quick Plunderer or Rapid Robber
Also Known As:
Description: Carnivore, Bipedal
Order: Saurischia
Suborder: Theropoda
Infraorder: Tetanurae
Micro-order: Maniraptora (of the microorder Coelurosauria)
Family: Dromaeosauridae
Height: 2.5 feet (0.8 meters)
Length: 5.9 feet (1.8 meters)
Weight: 200 pounds (91 kg)
Period: Late Cretaceous




Notes: Found in Mongolia, China and Russia, Velociraptor was a ferocious predator with the second toe of each foot bearing a formidably large, retractable claw. Velociraptor was similar in appearance to the larger Deinonychus and the much larger Utahraptor. Like Deinonychus and possibly Utahraptor, it may have hunted in packs -- although Velociraptor and Utahraptor fossils have never been found in groups like Deinonychus. Velociraptor was not as fast as a cheetah, nor as smart as a chimpanzee, as suggested in the movie Jurassic Park.


VOLKHEIMERIA
Pronunciation: VOL-kye-MEE-ree-ah  
Translation: Volkheimer's Lizard
Also Known As:
Description: Herbivore, Quadrupedal
Order: Saurischia
Suborder: Sauropodomorpha
Infraorder: Sauropoda
Family: Brachiosauridae
Height: 8 feet (2.4 meters)
Length: 22 feet (6.7 meters)
Weight:
Period:
Middle Jurassic


Notes: Volkheimeria is less than half as large as Patagosaurus and with more primitive spinal bones. Named in honor of Wolfgang Volkheimer, Argentine paleontologist.


VULCANODON
Pronunciation: vul-CAN-uh-don  
Translation: Fire Tooth, or Volcano Tooth
Also Known As:
Description: Herbivore, Quadrupedal
Order: Saurischia
Suborder: Sauropodomorpha
Infraorder: Sauropoda
Family: Vulcanodontidae
Height: 8 feet (2.4 meters)
Length: 20 feet (6.1 meters)
Weight: Period: Early Jurassic


Notes: Discovered in Zimbabwe, Vulcanodon is one of the most primitive sauropods known. Its bones had a mixture of prosauropod and sauropod features.
