Skull Island’s isolation has seen an explosion of diversity among its endemic lizard species, with many developing limited flight capabilities, or gliding - including Discus, feather devils, aerosaurs, and dracos. One group in particular, unique to the island but part of the agamid (or dragon lizard) family, has developed close to a dozen species. These are the remarkable and often spectacular flizards.
- Alatusaurus sanguideia (6-8 inches long). The fiery-scaled A. sanguideia is one of the most common species in the successful flizard genus Alatusaurus, commonly called typical flizards. This species has a long whip-like tail, fully two thirds of their total length, and a thorny head. Males have the most pronounced spikes on their tiny skulls and use them to intimidate one another. They live on small insects.
- Wing-Foot, Aliepesaurus ferox (5-7 inches long). Closely related to typical flizards, this species has small wing planes between their toes and a primary wing membrane that has migrated forward to run along the forearms, supported in gliding by their elongated little digits.
- Alatusaurus cinnabaris (7-10 inches long). The brilliant A. cinnabaris is a fearless hunter of small invertebrates. A plucky little predator, it darts close to big dinosaurs, grabbing arthropods that are disturbed in their destructive wake.
- Grand Flizard, Alatusaurus pergrandis (10-13 inches long). The largest of the flizards, the grand flizard can glide only short distances but is a strong climber. Males have short hornlike crests over their eyes for territorial fights. Each male grand flizard will try to force his rival off a contested branch, their short horn crests locking like miniature ceratopsians.
- Alatusaurus scintilla (4-6 inches long). A vivid berry-eating species, A. scintilla males show off their fire-engine-red colorations to impress females in the dark jungle.
- Novusaurus biscutica (6-7 inches long). Sole representatives of their genus, Novusaurus have forked tails and odd cheek wings. They eat only butterflies.
