Squamata
(lizard family) appeared around 195 million years ago in the Triassic
Period, Chameleonidae Family appeared nearly 100 million
year ago during the Cretaceous Period. Fossil remains have been
found in Bavaria. Some
experts consider Mimeosaurous (from Mongolia in the upper
Cretaceous Period ) to be related to true
chameleons.
The oldest proven ancestor from fossil is the Chameleo caroliquarti
from
approximately 26 million years ago. Fossils have been found in a much
wider range than chameleons inhabit today.
