Which of the following statements proves that scientific knowledge changed due to the discovery of the fossil of a hadrosaur in north dakota? hadrosaurs were better runners than earlier thought. hadrosaurs had no pattern on their skin as expected. the length of the hadrosaur was shorter than previously thought. the muscular structure of hadrosaurs was less developed than expected.

Hadrosaurs were better runners than earlier thought

Explanation:

Before this discovery, the fossils for Hadrosaurs were incomplete in different types area of its body. So, they only use prediction to guess the type of bones that might fill the missing piece and formulate their hypothesis regarding Hadrosaurs speed from there.

The findings in north dakota indicates that Hadrosaurs have heavier tails than it originally expected. Among mamals, this would mean that their speed will become slower due to the increase of bodyweight. But, Most reptiles can use  their tails to help them accelerate their speed, which is why they can draw a conclsuoion that  Hadrosaurs were better runners than earlier thought
