Threehorn is the Land Before Time term for Triceratops, it is the dinosaur that Cera's dad Daddy Topps is as well as Cera, Tria, Tricia, Dinah and Dana. They are so named due to their having three horns, a small one just behind their nose and two above their eyebrows that point forward and slightly to the sides. This name possibly applies to other chasmosaurine ceratopsians as well such as Chasmosaurus, Pentaceratops, and Torosaurus but this has not been confirmed. At one point, after offering a Tree Sweet to Tria, Topps tells Cera that threehorns can do anything they set their mind to like bashing things down from the trees.
