Many scientists believe birds evolved from dinosaurs. In their effort to prove this hypothesis, scientists appreciate hard evidence of similarities between the two types of creatures, including their reproductive biology.
“We can give a hypothesis, but it’s often very difficult to confirm the hypothesis,” Sato said. “Our specimen gives direct, undoubted evidence” that dinosaurs shared with birds some aspects of reproductive behavior.
Hans-Dieter Sues is the associate director for research and collections at the Smithsonian Institution’s National Museum of Natural History in Washington, D.C. He said the find is “very interesting” but not unexpected, as it was predicted by previous studies.
“Still, it is neat to find such a fossil,” he said. Sues is a member of the National Geographic Society’s Committee for Research and Exploration.
An excellent addition to Dinosaur Adventure Land. No, really.
