Recently I was in France and was susprised to see a newt which is widespread in northern Iberia, reaching central areas of France.
The Marbled newt belongs to the group of the crested newts (T. cristatus, T. carnifex, etc.) and the ancestor of this species and T. pygmaeus (the Pygmy Marbled Newt) evolved in the Iberian Península, its presence in France may be the result of a post-glacial expansion in the last 10 000 years.
