About this 3D model
Available sizes Medium – 1:35 of the actual size | Normal, Hollow & Pre-supported versions Description Stethacanthus altonensis was an unusual prehistoric shark that lived during the Late Carboniferous period, around 300 million years ago. Known from fossil remains found in what is now North America, this species is especially famous for its bizarre dorsal fin. Adult males possessed a large, flat, anvil-shaped spine covered in rough denticles, possibly used for display, mating, or intimidation. Unlike modern sharks, Stethacanthus altonensis had a compact body and broad pectoral fins, suggesting agile movement in shallow marine environments. Its teeth indicate a diet of small fish and invertebrates, making it a distinctive early experiment in shark evolution. Additional Details Chitubox file provided if you want to resize the model.
