However, the description was published in a very preliminary format, being not complete at all, having issues with preserved elements and numerous typographical errors. Due to a misinterpretation, the pedal ungual II (or sickle claw) was claimed to be preserved and to articulate with the pedal phalanx II, however, this was corrected by Senter in 2007 and this ungual actually represents a manual one. Turner and colleagues in 2012 during their large revision of the Dromaeosauridae stated that the describing paper of "Achillobator" was likely published without the knowledge of the two latter paleontologists as indicated by a draft left in Mongolia in 1997.
