Scientists have found a living population of a beautiful, dragon-like lizard in Indonesia. The only example previously known to science was a single individual preserved in a jar in 1891. 

This beautiful agamid lizard changes colors like a chameleon, walks with the rocking gate of a chameleon to blend in, and looks just like a dragon from fairy tale books for children.

Here is a pdf of the information about the lizard published in a scientific journal:

REDISCOVERY OF MODIGLIANI’S NOSE-HORNED LIZARD, Harpesaurus modiglianii VINCIGUERRA, 1933 (REPTILIA: AGAMIDAE) AFTER 129 YEARS WITHOUT ANY OBSERVATION
