An article published in the journal “Nature Communications” describes the extraordinary study on the eyes of fossilized specimens of Dollocaris ingens, a crustacean that lived about 160 million years ago, in the middle Jurassic. In the deposits of La Voulte, in the southeast of France, fossils were found in which various soft tissues were also well preserved and this allowed to reconstruct their eyes, giving us an idea of ​​how they saw and indirectly of the environment in which they lived.
