On Halszkaraptor's place in evolution

Here’s something I’ve been pondering. Is Halszkaraptor convergent or transitional?

Convergent with what? Transitional to what? Are you asking if it’s a duck?

Duck, swan, goose, something like that. I was just basically wandering if there is a connection with it or not.

OK, that’s easy: no, there is no connection. Halszkaraptor is a dromaeosaur, and anseriforms are deeply embedded in Neornithes (= crown group Aves). Quite different branches of Maniraptora.

Doesn’t it depend on whether LizardOfDoom is asking about duckness or about other features seen in both Halszkaraptor and in birds? It would depend on an ancestor state reconstruction, I suppose.

OK, I see the question is “duck, swan, goose …. something like that”. In this case if it walks like a duck, quacks like a duck, etc then it still isn’t a duck and duckness would have developed separately in Halszkaraptor.
