Komodo dragon collision between Australia and Southeast Asia allowed these larger varanids to move back into what is now the Indonesian archipelago, extending their range as far east as the island of Timor. The Komodo dragon was believed to have differentiated from its Australian ancestors 4 million years ago. However, recent fossil evidence from Queensland suggests the Komodo dragon actually evolved in Australia before spreading to Indonesia. Dramatic lowering of sea level during the last glacial period uncovered extensive stretches of continental shelf that the Komodo dragon colonised, becoming isolated in their present island range as sea levels rose afterwards.

Bolsón night lizard Bolsón night lizard The Bolsón night lizard ("Xantusia bolsonae") is a species of night lizard described by Webb in 1970. It is endemic to the state of Durango in Mexico. Not much is known about the lizard at present, as it appears to be simultaneously rare and rather secretive in nature. The Bolsón night lizard is predictably small, due to its behaviour and habitat. They tend to be around 6 centimetres in bodily length, with a similar tail length proportionate to body size. The body is primarily covered by scales, totalling 50 in the dorsal region, featuring leopard print markings
