Lizards range in size from chameleons and geckos a few centimeters long to the 3-meter-long Komodo dragon. Most lizards are quadrupedal, running with a strong side-to-side motion. Some lineages (known as " legless lizards ") have secondarily lost their legs, and have long snake-like bodies.
The plant is considered a living fossil. Radiocarbon dating has confirmed that many individuals have lived longer than 1,000 years, and some are suspected to be older than 2,000 years.

The Lapitiguana is the largest iguana fossils. The extant members of genus Brachylophus are iguanas small and medium-sized, growing a length of 60–75 cm (24–30 in). ). Although, in the past there was a much larger member of this family – Brachylophus gibbonsi, reached in length of 1.2 m (3.9 ft), [citation needed] and thus, was 1.8 times longer than its modern re
