It looks to be a reasonable article published in a reasonable journal not some crank or pay-to-play journal. More likely, a hyena expert saw the flute and thought "that looks exactly like a bone eaten by a hyena" and did some research. Most archeology in my country is performed by private organizations. There is nothing suspicious about that. I don't know who is right but a pile of badly made attempts at a flute would probably prove they were made by archaic humans, not a random hyena feast.
