Helicoprion Scale:1:20 approximately 154-150 million years agoHelicoprion ( H. ergassaminon , 'Saw coil') is a genus of extinct cartilaginous fish that resembled sharks in appearance and behavior. This genus first emerged in the oceans of the Late Carboniferous, approximately 290 million years ago, and survived the Permian Triassic mass extinction, which occurred about 252 million years ago. However, it finally became extinct in the Late Triassic, approximately 225 million years ago. The most remarkable feature
