BACTROSAURUS
Pronunciation: BAK-truh-SAWR-us  
Translation: Bactrian Lizard
Also known as:
Description: Herbivore, Bipedal
Order: Ornithischia
Suborder: Ornithopoda
Infraorder: Iguanodontia
Family: Hadrosauridae
Height: 8 feet (2.4 meters)
Length: 20 feet (6.1 meters)
Weight:
Period: Late Cretaceous


Notes: Bactrosaurus is one of the earliest known duck-billed hadrosaurs. It had fewer teeth than did later hadrosaurs. It lived in what is now Mongolia.


BAGACERATOPS
Pronunciation: bag-uh-SAIR-uh-tops  
Translation: Small Horned Face
Also known as:
Description: Herbivore, Quadrupedal
Order: Ornithischia
Suborder: Marginocephalia
Infraorder: Ceratopsia
Micro-order Neoceratopsia
Family: Protoceratopsidae
Height: 12 inches (0.3 meters)
Length: 36 inches (0.9 meters)
Weight: 7 pounds (3.2 kg)
Period: Late Cretaceous


Notes: Discovered in the Gobi desert of Mongolia, Bagaceratops was a small, primitive ceratopsian. It had a very small horn on its nose and its neck was protected by a very short frill. Glossary In Asia, the protoceratopsians were prevalent during the Late Cretaceous, while no certain neoceratopsians are known, whereas at the same time in North America, the neoceratopsians were more prevalent and only a few protoceratopsians have been discovered.


BAHARIASAURUS
Pronunciation: buh-HAR-ee-uh-SAWR-us  
Translation: Baharije Lizard
Also known as:
Description: Carnivore, Bipedal
Order: Saurischia
Suborder: Theropoda
Infraorder: Tetanurae
Micro-order: Carnosauria
Height: Length:
Weight: Period: Cretaceous


Notes: The name was given to fragmentary remains found in Egypt. It was probably similar to Megalosaurus.No further study of Bahariasaurus is possible until new specimens are identified, for its remains were destroyed in the World War II bombing of Stuttgart, Germany.


BARAPASAURUS
Pronunciation: buh-RAP-puh-SAWR-us  
Translation: Big Leg Lizard
Also known as:
Description: Herbivore, Quadrupedal
Order: Saurischia
Suborder: Sauropodomorpha
Infraorder: Sauropoda
Family: Vulcanodontidae
Height: 25 feet (7.6 meters)
Length: 60 feet (18.3 meters)
Weight:
Period: Early Jurassic


Notes: Known from parts of over 300 individual specimens found in India yet no skulls have been recovered. Barapasaurus is the oldest known sauropod certain to have been a sauropod, however; Vulcanodon may be older. While Barapasaurus gathered in herds, as did many sauropods, it differed in that it had comparatively slender legs.


BAROSAURUS
Pronunciation: BARE-uh-SAWR-us  
Translation: Heavy Lizard
Also known as:
Description: Herbivore, Quadrupedal
Order: Saurischia
Suborder: Sauropodomorpha
Infraorder: Sauropoda
Family: Diplodocidae
Height: 40 feet (12.2 meters)
Length: 79 feet (24.1 meters)
Weight: 50,000 pounds (22,680 kg)
Period: Late Jurassic


Notes: Barosaurus is a relatively rare sauropod. The first dinosaur to be found in the Black Hills of South Dakota, its remains have also been found in East Africa suggesting the connection of the modern African and North American continents during Late Jurassic times. The neck of Barosaurus was 30 feet long, longer than its closest relative, the whip-tailed giant Diplodocus but its tail was shorter and its hind limbs stockier. Gastroliths were discovered among its the bones, indicating that at least some dinosaurs swallowed stones to grind the food they consumed.


BARYONYX
Pronunciation: bare-ee-ON-iks  
Translation: Heavy Claw
Also known as:
Description: Carnivore, Bipedal, semi Quadrupedal
Order: Saurischia
Suborder: Theropoda
Family:
Height: 6 feet (1.8 meters)
Length: 30 feet (9.1 meters)
Weight: 4,000 lbs (1,814 kg)
Period: Early Cretaceous





Notes: Discovered in southern England, Baronyx had a huge curved claw over 12 inches (30-cm) in length on each hand. Its long narrow jaws were equipped with small pointed teeth, twice as many as a theropod would normally have, which leads many to think that Baryonyx was a fisher. It might have waded in shallow water to spear fish with its claws.


BELLUSAURUS
Pronunciation: BEL-uh-SAWR-us  
Translation: Beautiful lizard
Also known as:
Description: Herbivore, Quadrupedal
Order: Saurischia
Suborder: Sauropodomorpha
Infraorder: Sauropoda
Family: Cetiosauridae (not confirmed)
Height: Length: 16.4 feet (5 meters)
Weight: Period: Middle Jurassic


Notes: Sauropod skulls were small and light-boned, and finds are rare, but a complete Bellusaurus skull exists, showing that this very small sauropod had a deep head with a sloping face. There is a possibility that all Bellusaurus finds may be juveniles, hence their small size.


BOTHRIOSPONDYLUS
Pronunciation: bah-three-uh-SPON-dih-lus  
Translation: Excavated Vertebrae
Also known as: Marmarospondylus
Description: Herbivore, Quadrupedal
Order: Saurischia
Suborder: Sauropodomorpha
Infraorder: Sauropoda
Family: Brachiosauridae
Height: 35 feet (10.7 meters)
Length: 66 feet (20.1 meters)
Weight:
Period: Late Jurassic


Notes: Bothriospondylus is known from fragmentary remains discovered in Western Europe and Madagascar. This sauropod had large teeth and a long tail. Its forelegs were approximately as long as its hind legs.


BRACHIOSAURUS
Pronunciation: BRACK-ee-uh-SAWR-us  
Translation: Arm Lizard
Also known as:
Description: Herbivore, Quadrupedal
Order: Saurischia
Suborder: Sauropodomorpha
Infraorder: Sauropoda
Family: Brachiosauridae
Height: 50 feet (15.2 meters)
Length: 100 feet (30.5 meters)
Weight: 120,000 lbs (54,432 kg)
Period: Late Jurassic


Notes: Brachiosaurus is one of the largest known land animals, based on a complete skeleton found in Tanzania. Each neck vertebra was more than 3 feet (1 meter) long. Its large nostrils were located on top of its head, which caused speculation that Brachiosaurus might have spent time submerged in water. However, recent studies have shown that a creature as large as Brachiosaurus could not have inhaled and inflated its lungs against the water pressure at depths of total submergence. Its front legs were longer than its rear legs and it stood 24 feet (7.3 meters) at the shoulder. It had small narrow feet for its size and the first digit of the front foot had a claw as did the first three digits of the hind foot. The function of the claws is unknown though they may have been used for raking plants or in self defense.


BRACHYCERATOPS
Pronunciation: BRAK-ee-SAIR-uh-tops  
Translation: Short Horned Face
Also known as:
Description: Herbivore, Quadrupedal
Order: Ornithischia
Suborder: Marginocephalia
Infraorder: Ceratopsia
Micro-order Neoceratopsia
Family: Ceratopsidae
Height: 2 feet (0.6 meters)
Length: 6 feet (1.8 meters) (Juveniles)
Weight:
Period: Late Cretaceous


Notes: Information about Brachyceratops is known primarily from young specimens discovered in Montana. Their short faces and frills were only half developed. At the same dig, an adult ceratopsian was discovered, indicating that the young specimens were part of a family unit.


BRACHYLOPHOSAURUS
Pronunciation: brack-ee-LO-fuh-SAWR-us  
Translation: Short-Crested Lizard
Also known as:
Description: Herbivore, Bipedal
Order: Ornithischia
Suborder: Ornithopoda
Infraorder: Iguanodontia
Family: Hadrosauridae
Height: 12 feet (3.7 meters)
Length: 28 feet (8.5 meters)
Weight:
Period: Late Cretaceous


Notes: Known from nearly complete material found in Montana, and Alberta, Canada, this duck-billed dinosaur walked on its hind feet and ate the leaves of plants and flowers.


BRADYCNEME
Pronunciation: BRAY-dee-kuh-NEE-mee  
Translation: Slow Leg or Heavy Shin
Also known as:
Description: Carnivore, Bipedal
Order: Saurischia
Suborder: Theropoda
Infraorder: Tetanurae
Micro-order: Maniraptora (of the microorder Coelurosauria)
Family: Tro”dontidae(not confirmed)
Height:
Length:
Weight:
Period: Late Cretaceous


Notes: Bradycneme is known only through a portion of a lower leg bone with a distinctive ankle joint. At one time, it was thought to be the fossil leg of a giant owl. The fossil was discovered in Transylvania.
