How did the wing structure of Waimanu differ from modern diving specialists?
Answer
Its bones did not exhibit the extreme flattening seen in modern diving specialists
While Waimanu was flightless and utilized wing-propelled diving, the fossil record shows that its wing bones were not yet specialized with the extreme flattening found in modern penguins. This lack of specialized morphology indicates that Waimanu likely possessed less aquatic grace and speed than contemporary species, suggesting a swimming style that was less efficient but sufficient for its specific Paleocene environment.
