noun a class of extinct jawed fishes that lived from the Silurian to the Permian period
Acanthodians are used as index fossils in stratigraphy to date rock layers.
Acanthodians are considered to be early jawed vertebrates and are important in understanding the evolution of vertebrates.
Acanthodians are of interest to ichthyologists studying the diversity and morphology of ancient fish species.
Acanthodians are an extinct group of jawed fish that lived during the Silurian and Devonian periods.
Acanthodians are studied for their unique anatomical features and their relationship to other vertebrate groups.
Acanthodians play a role in reconstructing ancient marine ecosystems and understanding trophic interactions.
Acanthodians are significant in the history of vertebrate evolution and the development of modern fish.
Acanthodian fossils have been studied extensively by paleontologists and are often mentioned in scientific papers and articles written by writers specializing in paleontology.
Paleontologists have conducted research on acanthodians to understand their evolutionary history and ecological roles in ancient ecosystems.
Biologists studying fish evolution may reference acanthodians as important early jawed fish in their research and publications.
Geologists may study the sedimentary rocks where acanthodian fossils are found to understand the paleoenvironment in which these ancient fish lived.
