![]() ![]() It is therefore likely that turtles originated from a Permian-Triassic archosauromorph ancestor with two pairs of temporal fenestrae behind the skull orbit that were subsequently lost. This is the first statistically significant molecular phylogeny on the placement of turtles relative to the archosaurs and lepidosaurs. Generally the body is brown or black with 5 white or. Following the 5-year review for sand and bluetail mole skinks (Service 2007) and our assessment of the skink surveys to date, the Service provides this revised skink survey protocol for all counties in Florida in which they occur: The three most important factors in determining the presence of skinks are location, elevation, and suitable soils. The tail, blue in juveniles and pinkish with age, is a little more than half the body length. A moderately large, shiny lizard (5.0 to 8.5 inches in length) with highly variable color pattern. The phylogenetic analyses further suggested that turtles are a sister group of the archosaurs, and this untraditional relationship was provided with strong statistical evidence by both the bootstrap and the Kishino-Hasegawa tests. The blue-tailed mole skink, Eumeces egregius lividus, has short, stubby legs and a thin, cylindrical body measuring from 3.6-5.2 in (9-13 cm). In spite of this rate heterogeneity, phylogenetic analyses using amino acid sequences of 12 mitochondrial proteins reliably established the Archosauria (birds and crocodilians) and Lepidosauria (lizards and snakes) clades postulated from previous morphological studies. Molecular evolutionary rates of mitochondrial protein sequences appear to vary considerably among major reptilian lineages, with relatively rapid rates for snake and crocodilian lineages but slow rates for turtle and lizard lineages. These genomes possess an organization of genes which is typical of most other vertebrates, such as placental mammals, a frog, and bony fishes, but distinct from organizations of alligators and snakes. In order to address this, complete mitochondrial DNA sequences were determined for the green turtle and the blue-tailed mole skink. Previous molecular studies have not established a consistent and statistically well supported conclusion on this issue.
