"Enormous herbivores with long necks and tails and small heads, Sauropods evolved their distinctive necks as a way to obtain hard-to-reach food sources, such as the foliage at the tops of trees. The Apatosaurus is one of the Sauropodan dinosaurs."
- Rapid Tooth Replacement (Speed):
"With huge appetits to fuel their massive size, Sauropods' broad, blunt teeth would be lost and regrow quickly to compensate for wear and tear."
- Gastroliths (Payout):
"A gastrolith is a rock or stone that is ingested by an animal and held inside their gastrointestinal tract to aid in the grinding of food for proper digestion."
- Quadrupedal (Speed):
"A creature that walks on four legs, with a horizontal posture, is called a quadruped. Many dinosaurs were quadrupedal, including Stegosaurus and Triceratops. A quadrupedal gait gave these dinosaurs increased sturdiness and the ability to carry lots of weight."
- Herbivore (Payout):
"Animals that feed entirely on plant matter are called herbivores. About half of all dinosaurs were herbivores. They had teeth that were specially designed for grinding leaves, twigs, and shoots."
- Jurassic Age (Discount):
"The Jurassic (201.3 MYA—145 MYA) was the second period of the Mesozoic Era. During this period, dinosaurs became the dominant species on Earth as the supercontinent Gondawana began to split, replacing the deserts of the Triassic with lush rainforests."
- Hollow Bones (Speed):
"The development of hollow or semi-hollow bones gave some dinosaurs a lighter but stronger skeleton system. This development would later enable them to evolve the ability to fly."
- Herd Behavior (Payout):
"Some dinosaurs concregated in social groups, living in loose family units for defense against predators."
- Feathers (Discount):
"It is still unknown to what extent therapodian dinosaurs were feathered, but evidence exists that shows that at least some of them presented with varying degrees of feathery skin coverings."
- Warm Climate (Payout):
"During the Mesozoic Era, the Earth's temperature was very warm, which led to a great amount of geological and biological transitions. This climate set the stage for the major changes of the era."
- The Dinosaur Formerly Known as Brontosaurus (75 Sauropods):
"Paleontologist Othniel Charles Marsh discovered the remains of a previously unknown sauropod in 1877 and named it Apatosaurus. He discovered another sauropod specimen two years later and named it Brontosaurus—not realizing that they were the same dinosaur."
- Whip It Good (200 Sauropods):
"Computer modeling suggests that thin, long, tail of Apatosaurus and other diplodocids could be cracked like a whip, and would produce a sound of over 200 decibels—about as loud as a cannon being fired."
