If correct, it would have been the world's oldest, having been hatched in 1859. [90] Orange roughy, also known as deep sea perch, can live up to 149 years. [91] George the lobster (an American lobster, Homarus americanus) was estimated to be about 140 years old by PETA in January 2009. [92]
The oldest undisputed lizards date to the Middle Jurassic, from remains found In Europe, Asia and North Africa. [53] Lizard morphological and ecological diversity substantially increased over the course of the Cretaceous. [54] In the Palaeogene, lizard body sizes in North America peaked during the middle of the period. [55]

Most of them are interspersed and can remain active. The longest L2 element found is 4 kb long and 83% of the sequences had ORF2p completely intact. The CR1 element is the second most repeated (4%). Phylogenetic analysis shows that these sequences are very different from those found in other nearby species such as lizards.
