New fossil of 9-foot-long tusked fish prompts paleontologists to reconsider giant salmon’s nickname.
Oncorhynchus rastrosus. CT model of holotype, skull in right lateral view with a stylized drawing of the originally proposed “sabertoothed” position of the isolated premaxilla; anterior view of skull, prior to complete preparation and CT scan; artist’s rendering skull of male iconic fish with accurate spike-tooth configuration; artist’s rendering of complete female iconic fish with accurate spike-tooth configuration.
After the researchers analyzed those fossils, performed CT scans on them, and compared them to the earlier specimens, they determined that the salmon’s teeth jutted out sideways, more like tusks than fangs.
