Neogene fish of Europe

Megalolamna is an extinct genus of large mackerel shark that lived approximately 23.5 to 15 million years ago (Mya), from the Late Oligocene to the Middle Miocene epochs. Fossils belonging to this genus are known from the Americas, Europe and Japan, and have been documented in scientific literature since the late 19th century. It was in 2016 that the fossils were described as belonging to the same distinct taxon called M. paradoxodon. However, a 2024 study reveals that the taxon was already described indirectly in 1879 under the name Otodus serotinus, the only known species of this genus then

Parotodus, commonly known as the false-toothed mako shark (or false mako shark), is an extinct genus of mackerel shark that lived approximately 53 to one million years ago during the Eocene and Pleistocene epochs. Its teeth, which are found worldwide, are often prized by fossil collectors due to their rarity. The scarcity of fossils is because Parotodus likely primarily inhabited open oceans far away from the continents. While the placement of Parotodus with the Lamniformes has been debated, most researchers agree it was probably a member of a now extinct shark clade, either a otodontid or a
