The Alamosaurus was a long-necked dinosaur that lived in the Jurassic and Cretaceous Periods. They also appeared in The Magic School Bus episode, The Busasaurus.
Role in The Busasaurus[]
When Ms. Frizzle, Liz and the class first arrived in the Cretaceous Period after time traveling back 67 million years, the Alamosaurus appear as the first dinosaur the class encounter when they're in the third era. When the kids first see the Alamosaurus, they get terrified and run off at first. After Arnold and Phoebe, run after an Ornithomimus after it stole and egg Arnold had that belonged to Ms. Frizzle's old friend, Dr. Carmina Skeledon, a young Alamosaurus approaches Keesha and Wanda. The young Alamosaurus then grabs a leaf Keesha was holding with it's mouth rising her up into the air causing her to freak out. The other Alamosaurus approach a tree Carlos, Ralphie, Tim and Dorothy Ann climbed. Carlos gets extremely scared thinking it was going to eat them, but Tim notices it wants to eat the leaves, and not them. But Carlos refuses to believe Tim knowing they're still dinosaurs. The Alamosaurus then leave and Ralphie tells everyone to get back onto the bus before they come back, but Dorothy Ann tells him the Alamosaurus are herbivores, and not carnivores. Carlos however thinks they were just taking a break between the salad and the main course, which was them, but Tim tells him that salad was the main course. Liz then runs up to Ms. Frizzle and poses as Arnold, Phoebe and the Ornithomimus they ran after. Carlos then fears that Arnold and Phoebe might have gotten eaten, so the class sets off to go look for them.
