#ExtinctFishoftheDay: Belantsea, a tiny cartilaginous ratfish (Holocephali) from Bear Gulch, Montana. It was an agile reef fish with a beak of "fangs". It's unclear whether it moved like a tang, frogfish, or stingray given enlarged fins and flattened fossils

#ExtinctFishoftheDay Harpagofututor, another Carboniferous "eel" related to ratfish/ghost sharks (Holocephali), with toothplates for shell-crushing. The name ("grappling hook copulator") is for the males' head-clasper "antlers", which females bit during mating! (Nix Illustration)
