Summary
| Description |
Diplacanthus striatus (Agassiz, 1835) fossil fish from the Lower Devonian of Scotland (public display, FMNH PF 2198, Field Museum of Natural History, Chicago, Illinois, USA). Acanthodians are an extinct group of jawed fish that had spines along the anterior margin of each fin (see the blackish-colored spikes on the specimen shown here). The root word “acanth” in “acanthodian fish” means “spine”. Acanthodians were the first fish to evolve jaws and scales. Classification: Animalia, Chordata, Vertebrata, Acanthodii, Climatiiformes, Diplacanthida, Diplacanthidae |
