Apparently "sabre-toothed" salmon is really a misnomer - more like tusked salmon.

Another very cool fossil site in LA is the La Brea Tar Pits museum, which still has tar pits on the museum grounds, and has real sabre-tooths (lions) and other critters like mammoths that got trapped in the tar pits.

Misnomer? I don't agree.
Its definitely "a big pointy tooth dominating the mouth" kind of feature.
Could also have been called a snaggle-tooth salmon, I guess ..
In any case, definitely an interesting fish.
