Prehistoric Period

No evidence of the blue-tailed skink, or Eumeces elegans, as a separate species has been found in fossils from the Jurassic era. Still, it's crucial to remember that the blue-tailed skink is a member of the Scincidae family of skinks, which has a rich evolutionary history that begins in the Mesozoic times.

The global distribution of skink and similar lizard fossils provides further evidence of their long and storied evolutionary history. Reptiles had a period of great diversity throughout the Mesozoic Era, which began around 252 million years ago and ended about 66 million years ago.

Although certain skink species, such as the blue-tailed skink, may not have been around at the time, it is very probable that ancestors of the modern skinks did. Several speciation events and adaptations would have occurred over millions of years on the same evolutionary route that resulted in the blue-tailed skink's appearance.

Several groups of lizards with features similar to current skinks have been discovered in the fossil record, which offers insights into the evolutionary paths of reptile lineages.

Over a long period of time, influenced by environmental changes and natural selection, the blue-tailed skink evolved into its modern form via a process of adaptation, ecological specialization, and geographic dispersion.

Although there is no direct proof of the blue-tailed skink in ancient fossils, its lineage is nonetheless important for reptile evolution as a whole. This species is a modern-day example of how ecological responsibilities and adaptive tactics have evolved and progressed.

The intricate relationships between species and their surroundings throughout Earth's history may be better understood by delving into the evolutionary history of skinks and related lizard families.
