Antarctopelta is the second named dinosaur (the first being Cryolophosaurus) discovered from the continent of Antarctica (actually from the North James Ross Island). The fossil has been located in 1986 but it took many years to exhume it due to the frozen conditions of the site. It was a medium size ankylosaur with features pertaining to both the nodosaurids and the ankylosaurids.
