"Gallimimus was a large, bird-like herbivore that traveled in herds and built nests."
- Nest Building (Speed):
"Large fields of fossilized dinosaur nests have been discovered in many areas, giving insight into how some dinosaurs protected their eggs and young as a community."
- Three-Toed Feet (Payout):
"Walking on three distinct toes, instead of flat feet, allowed dinosaurs to lengthen their stride and increase their speed. This improved their hunting and evasion."
- Bipedal (Speed):
"A creature that walks on two legs, with an upright posture, is called a biped. Some dinosaurs were bipedal, including Tyrannosaurus Rex, Velociraptor, and Hadrosaur. A bipedal gait gave these dinosaurs increased speed and flexibility."
- 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."
- Cretaceous Age (Discount):
"The Cretaceous (145 MYA—66 MYA) was the last period of the Mesozoic Era. Dinosaurs continued to dominate the Earth. Flowering plants first appeared during this time. This period ended with the Cretaceous-Paleogene Mass Extinction Event, when 75% of all life on Earth went abruptly extinct."
- 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."
- Safety in Numbers (75 Gallimimus):
"Paleontologists believe that Gallimimus may have lived and traveled in groups. Their nature as grazers would have meant that these emu-like dinosaurs needed to rely on herd for safety against predators."
- Radioactive Dinosaurs! (200 Gallimimus):
"Remains of the Gallimimus have been found mostly in the Gobi Desert. The fossils found in this area have unusually high levels of radioactivity, as deposits of uranium in the ground water led the bones to become saturated with the element."
