| 説明 | Smilodon sp. - saber-toothed tiger skull from the Pleistocene of California, USA. (Orton Geology Museum, Ohio State University, Columbus, Ohio, USA) [this looks like a replica]This is the famous, fearsome-looking saber-toothed tiger, Smilodon. Several fossil cats are known with hyper-enlarged canine teeth. These fangs helped the cats bring down large prey animals. Smilodon is known from the Late Pliocene and Pleistocene of the Americas. An especially prolific locality for Smilodon fossils is the La Brea Tar Pits of California’s Los Angeles Basin.By the way, some will insist that the traditional term "saber-toothed tiger" is incorrect. Common names do not have scientific significance - they never have. I would recommend that people "chill" when it comes to common names. As an anothern example, many do not call starfish "starfish" anymore, the logic being that they are not fish (which is true). Their common name is now frequently "seastars". Well, they aren't stars, either. "Starfish" is fine - no one thinks they are fish. Chill.------------------------------From exhibit signage:Rancho La BreaAlthough the name of this site in downtown Los Angeles means "Ranch of Tar", the sticky material there is not tar but asphalt, formed by petroleum seeping to the surface and becoming thicker as volatiles evaporate. Mined for use on roofs and roads as early as the 1860s, the bones encountered were thought to be those of modern animals until the skull of a saber-toothed cat was found. Since the first scientific excavations in 1901, over 4 million fossils of over 650 species have been found, from beetles to mammoths, going back as far as 40,000 years.------------------------------Classification: Animalia, Vertebrata, Mammalia, Carnivora, FelidaeStratigraphy: La Brea Asphalt, PleistoceneLocality: La Brea tar pits, Los Angeles, California, USA |
