I want to know the answer to the following question:
Because of the construction of their shoulder bones, what were the enantiornithes called?
All the background I'm provided with is that "The first large, diverse lineage of short-tailed avialans to evolve were the enantiornithes, or "opposite birds", so named because the construction of their shoulder bones was in reverse to that of modern birds.". Is that enough to answer the question?
