After reading some paleontology primary sources, I'm inclined to regard pop sci articles like this as trifles. For each and every paleotontological theory, there is automatic gainsaying. Emphasizing the opposition part of the gainsaying is a mistake. Usually, opposition signifies problems with the original theory, but in paleontology, so much is unknown that an opposing theory means almost nothing, except that another interpretation can be summoned to explain the fossil.
