Acregoliath is an extinct genus of ray-finned fish that existed during the middle of Miocene epoch, about 13.76 to 13.34 million years ago. [1] It is known from very fragmentary remains which consist of several scales that were found in Brazil.
The study of prehistoric fish is called paleoichthyology. A few living forms, such as the coelacanth are also referred to as prehistoric fish, or even living fossils, due to their current rarity and similarity to extinct forms. Fish which have become recently extinct are not usually referred to as prehistoric fish.
Early fossil tetrapods have been found in marine sediments, and because fossils of primitive tetrapods in general are found scattered all around the world, they must have spread by following the coastal lines — they could not have lived in freshwater only.

The Cuche Formation contains unique Placoderm fish fossils, first noted by Mojica and Villarroel in 1984. [23] Across the section, also plant fossils and bivalves are found. In this part of the sequence the first fish fossils were discovered. The top section provided brachiopods (genus Lingula) and other at that moment undetermined fossil ...

The oldest identified coelacanth fossils are around 420–410 million years old, dating to the early Devonian. [ 1 ] [ 48 ] Coelacanths were never a diverse group in comparison to other groups of fish, and reached a peak diversity during the Early Triassic (252–247 million years ago), [ 49 ] coinciding with a burst of diversification between ...
Both Homo fossils and lithic instruments dating from this period have been found in Iberia. The most ancient of the fossils are a partial mandible of an unidentified Homo species (c. 1.2 Ma ago) and a maxilla still [as of?] pending identification (c. 1.4 Ma ago), both discovered in Sima del Elefante, Atapuerca.
