Lepisosteiform fish (Holostei) ganoid scales from the middle jurassic deposits of Ukraine
Gars (Lepisosteiformes) flourished in epicontinental seas throughout the world during the second half of Mesozoic and early Cenozoic. Cretaceous and Paleogene remains of these fishes are common in Europe while their Jurassic fossils are still relatively scarce. Here we re-describe in detail a series...
