The giant prehistoric 'sabre-toothed salmon' has been renamed the 'spike-toothed' salmon after scientists uncovered new information about its weird, giant tusks.A spike-toothed salmon fossil is shown on display at the University of Oregon. About five million years ago, the largest salmon known to have lived migrated through the coastal waters of the Pacific Northwest, and a new paper uses revelations from fossil discoveries to reimagine and rename the great fish.
"There were these two skulls staring at me with sideways teeth," said Davis, an associate professor in the department of Earth sciences at the university.The spike-toothed salmon is compared to the largest living salmon and a six-foot-tall fisherman. ) The salmon lived about five million years ago at a time when Earth was transitioning from warmer to relatively cooler conditions, Davis said.
Another co-author, Brian Sidlauskas, says a fish the size of the spike-toothed salmon must have been targeted by predators such as killer whales or sharks.
