       Jakapil is an interesting little dinosaur as it may represent not only a basal thyreophoran dinosaur,‭ ‬but possibly also for the time of its description,‭ ‬an unknown kind.‭ ‬Unfortunately the remains of the holotype individual are largely incomplete,‭ ‬but they do at least give us a tantalising glimpse at the jaw structure,‭ ‬general build and even spiny armour plating of this dinosaur.‭
       Jakapil seems to have been bipedal,‭ ‬and had large spiny armour running down its body,‭ ‬especially along its neck.‭ ‬Jakapil also had a strongly developed lower jaw.‭ ‬The describing authors speculated that instead of shearing and swallowing plants,‭ ‬Jakapil may have actually chewed‭ (‬masticated‭) ‬plant material first before swallowing.‭ ‬This could explain the strong development in the lower jaw as other types of dinosaur speculated to feed in this way often also have strongly developed lower jaws.‭ ‬This method of feeding and development can also be supported by the knowledge that the Candeleros Formation where the holotype of Jakapil was discovered was largely an arid desert-like habitat.‭ ‬In such an environment,‭ ‬only the toughest of plants could survive,‭ ‬and only the animals adapted to feed on them could live.
