Mystery Alien creature in Romulus

Mike from Mike's Monsters, who has seen the film's rough cut, mentioned in his reaction video what it is, which makes me excited to see how the full scene plays out in the film. And it’s all practical.  

Velociraptor. But seriously I think it's a xeno foot. If I recall correctly, Mike mentioned the old chap wasn't in the trailer so I guess it's another xeno waking up from a wall Aliens-style.
