In Depth

       Actinolepis is a genus of placoderm fish that lived during the Devonian period.‭ ‬Fossils of Actinolepis have usually been more associated with Eastern Europe,‭ ‬but at least one species of Actinolepis is known from fossil deposits in New Zealand.‭ ‬It is worth remembering that back in the Devonian the planets land masses were arranged very differently to how they are today and coming together to form a supercontinent before breaking apart again.‭ ‬This made it easier for some types of animals to have what appears today as a very large geographical range.
