Spike-toothed Salmon

Oncorhynchus rastrosus (originally described as Smilodonichthys rastrosus), also known as the saber-toothed salmon (now known to be a misnomer) or spike-toothed salmon, is an extinct species of salmon that lived along the Pacific coast of North America and Japan. They first appeared in the late Miocene in California, then died out some time during the Early Pliocene. They are members of the genus Oncorhynchus, which contains living pacific salmon.
