Multiple realities
(covers information from several alternate timelines)
The frilled-neck lizard (Chlamydosaurus kingii) was a species of lizard native to Australia and New Guinea on Earth.
In an alternate 1996, Rain Robinson owned a figurine of a frilled-neck lizard. This lizard had its frill fully extended, which was an indicator for territorial or courtship display. Robinson had placed the lizard on top of a computer monitor in her office at Griffith Observatory. (VOY: "Future's End")
