That most likely was a queen whose gestational host was a organism larger than a human being. Xenomorphs take a lot of the qualities of their hosts (those that were in dogs are quadrupeds and move fast, those in humans stand upright and have some intelligence, one inside a Gorilla would have long, ultra-strong limbs).

If it was far, far larger than a normal Xenomorph queen, perhaps it had a space jockey/engineer for a host...If you see that again let us know
