Diplomystus was a herring-like fish that lived mostly in the early Eocene, and was prolific in freshwater environments across the world. Diplomystus is recognisable by its upturned mouth, suggesting this fish was a surface feeder. These predatory fish fed on smaller species such as Knightia. Occasionally, fossils of smaller fish can be found lodged in the throats of large Diplomystus specimens!

We work closely with reputable suppliers all over the world to source high quality, genuine specimens. Each fossil comes with a certificate of authenticity documenting the provenance of each specimen, including the age and location where it was discovered.
