Brachiosauridae (Brachiosaurid)
Translation: Arm Lizards
Brachiosauridae (brak-ee-uh-SAWR-ih-day) is a family of sauropods with
front legs as long as or longer than their hind legs. They had spoon-shaped
teeth and were herbivores. The brachiosaurids were among the largest of
dinosaurs, some growing to be over 98 feet (30 meters) long. They lived
during the Jurassic and the Cretaceous Periods. Brachiosaurid bones have
been found all over the world.
Brachiosaurinae
Translation: Arm Lizards
Brachiosaurinae (brak-ee-uh-SAWR-ih-nay) is a subfamily of brachiosaurid
sauropods. Their front legs were longer than their hind legs. Bothriospondylus, Brachiosaurus, Pleurocoelus,
and Ultrasauros.
Brontosaurus
Translation: Thunder Lizard
Brontosaurus (BRON-tuh-sawr-us) is the name that was once given to a giant
sauropod. However, years after the fossil remains were named Brontosaurus,
it was discovered that the same fossil remains were also known by a different
name. Two years before they were named Brontosaurus, the same fossil remains
had been named Apatosaurus. Since the name Apatosaurus was given first,
it is considered to be the proper name of this sauropod. See also Cetiosaurs.
