Paleontologists have described a new genus of fossil fishes and together with the already known genus attributed to the family of anchovies. Large and powerful canine teeth point to a carnivorous way of life of these fish. They probably occupied an ecological niche, which was released after the Cretaceous-Paleogene extinction event. The authors of an article published in the journal Royal Society Open Science, point to a number of predatory fish that appeared in the early Paleogene, and assume that modern anchovies could occur from predators.
In the early Paleogene, a large variety of bony fishes — the majority of species originated in this period. Why believe the scientists, that after the Cretaceous-Paleogene extinction event opened up many ecological niches and new species were quick to adapt to these biological roles. So, as a result of the extinction of the disappeared a group of large predatory bony fishes, and on the boundary of the Paleocene and Eocene appeared mackerel, barracudas, and karancsi parusnikova fish. If these groups have developed through the Cretaceous-Paleogene extinction, and the other fish could use the opportunity to buy a new ecological role. However, such examples are studied a little.
