North America, South Dakota, Shannon County, White River Formation, Late Eocene to Early Oligocene Period, ca. 35 million to 29 million years ago. A rare and premium fossilized skull from Hoplophoneus primaveus, a false saber-tooth cat, in the Nimravid family. This saber-tooth creature has huge dagger line canine teeth, wonderfully on display with the lower jaw slightly gaping open, as if snarling! This is the second earliest saber-tooth carnivore that roamed North America beginning in the Oligocene Period. These animals shared many physical characteristics with the famous Smilodon (saber-toothed tiger) namely, the large saber canines; however, Hoplophoneus was not a true cat! The bone quality is magnificent, and the upper skull is outstanding, with definitive shape, including the sagittal crest! This creature is one of the most highly desired vertebrate fossils in the world due to its resemblance to Smilodon and extreme age! An extremely rare and special fossil! Size: 8.25" L x 5" W x 8" H (21 cm x 12.7 cm x 20.3 cm); saber teeth: 2.75" L (7 cm)
These animals were 2 feet tall (0.6 meters), the size of a large modern-day bobcat, and were more of a group predator with a close knit families as evidenced by some hoplos found together in death while overall very rare species hunting an abundant food supply of grazing ungulates including camels and oreodonts. Using their highly developed saber-teeth they would likely sever the blood supply in the neck of their prey in the initial attack. We cannot stress enough just how awesome and rare this fossilized skull is!
