Eoalosa janvieri gen. et sp. nov., a new clupeid fish (Teleostei, Clupeiformes) from the Eocene of Monte Bolca, Italy
Fishes of the family Clupeidae are extremely abundant in the Eocene fossiliferous limestone of Monte Bolca representing the most common group from this celebrated locality. A new clupeid from the Pesciara site, Eoalosa janvieri gen. et sp. nov., is described. The new taxon exhibits a unique combination of characters supporting its recognition as a new genus and species of clupeid fish that is t...
متن کاملHydrodynamics of fossil fishes
From their earliest origins, fishes have developed a suite of adaptations for locomotion in water, which determine performance and ultimately fitness. Even without data from behaviour, soft tissue and extant relatives, it is possible to infer a wealth of palaeobiological and palaeoecological information. As in extant species, aspects of gross morphology such as streamlining, fin position and ta...
متن کاملFifty million years of herbivory on coral reefs: fossils, fish and functional innovations.
The evolution of ecological processes on coral reefs was examined based on Eocene fossil fishes from Monte Bolca, Italy and extant species from the Great Barrier Reef, Australia. Using ecologically relevant morphological metrics, we investigated the evolution of herbivory in surgeonfishes (Acanthuridae) and rabbitfishes (Siganidae). Eocene and Recent surgeonfishes showed remarkable similarities...

متن کاملMallomonas schumachii sp. nov., a fossil Synurophyte bearing large scales described from an Eocene maar lake in Northern Canada
A new, and presumably extinct, species representing the genus Mallomonas, M. schumachii, is described from an Eocene maar lake situated near the Arctic Circle in northern Canada. The new species bears bristles and possesses three types of scales. Body scales are large, square-shaped, with a posterior rim encircling approximately half of the perimeter, a thick secondary layer of closely spaced h...
