Furcifer oustaleti (Oustalet’s Chameleon) is the longest chameleon species reaching lengths of 27 inches (68cm).
The word Brookesia is named after the British naturalist Joshua Brookes.
The largest chameleon species by weight is Calumma parsonii (Parson’s Chameleon).
The word Calumma comes from the Latin word for covering. This genus consists of chameleons from Madagascar with occipital lobes.
True chameleons include the following genera: Archaius, Bradypodion, Brookesia, Calumma, Chamaeleo, Furcifer, Kinyongia, Nadzikambia, Palleon, Rhampholeon, Rieppeleon and Trioceros.
The word Furcifer is derived from the Latin word “furci” or forked.
Chameleon fossils have been found in central Europe and China, indicating they were once much more widespread than they are now.
Chameleons have acrodont teeth meaning they are an extension of the jawbone. They are not set in sockets nor are they replaced.
The oldest known chameleon fossil is from the extinct species Chamaeleo caroliquarti. It was found in Europe and is 26 million years old.
Pygmy chameleons have bicuspid claws where each claw has two points like a crescent moon.
