Ischyodus
One of the stranger denizens of the sea covering Germany 150 million years ago, 3-foot-long Ischyodus is a close relative of modern chimaeroids (known also as rabbitfishes, or ghost fishes). This latter name comes from the spectral impression they create as they swim along with their metallic coloration and ribbon-like tail. Instead of separate teeth chimaeroids have massive upper and lower toothplates, which are used to crush prey.
