Late Jurassic tethyan ancestry of Recent southern high‐latitude marine isopods (Crustacea, Malacostraca)
Isopods are one of the key marine groups that radiated extensively in the southern high‐latitude regions, and it is widely assumed that they did so essentially through the Cenozoic era. Nevertheless, palaeontological evidence is now beginning to accumulate which suggests that some at least of the ke...

Isopods are one of the key marine groups that radiated extensively in the southern high‐latitude regions, and it is widely assumed that they did so essentially through the Cenozoic era.
