Falcatakely was originally interpreted as an enantiornithean, BUT some researchers like Mickey Mortimer have found it more similar to Sapeornis. This is not out of thin air as an omnivoropterygid-like sternum was found in the Maevarano Formation (O'Connor 2010). Then again, so were pengornithid-like material and Falcatakely as an enantiornithean is recovered next to Pengornis (O'Connor 2020), so it's a matter of personal preference at this point. I just though the omnivoropterygid interpretation needs more representation.
