Final answer:
The direct answer to the question is B. False. Edward Drinker Cope did not introduce the idea of aquatic sauropods in 1897; this idea came later and has since been challenged by new evidence within paleontology.
Step-by-step explanation:
B. False
The question asks if Cope introduced the idea of aquatic sauropods in 1897. To answer this question directly: B. False. Edward Drinker Cope, who was a prominent American paleontologist in the late 19th century, discussed many ideas related to dinosaurs and their habitat. However, the specific idea that sauropods were aquatic comes from a later time, as early depictions and understandings led some experts to depict these large dinosaurs with sprawling limbs as living in water to support their massive size. Over time, this viewpoint has been significantly challenged and revised, especially as more evidence has led to a better understanding of sauropod physiology, behavior, and environment. Therefore, while Cope contributed much to paleontology, he did not introduce the idea of aquatic sauropods in 1897 as suggested.
