Dinosaur
Apatosaurus
Deceptive lizard
Apatosaurus is the heavier-built Morrison diplodocid, the animal long called Brontosaurus (a name revived for some specimens in 2015). Its bones are massive and are sold as sections and slices of agatised limb bone; teeth are diplodocid pegs indistinguishable from Diplodocus. Agatised 'dinosaur bone' cabochons from Utah are mostly sauropod and rarely identifiable to genus.
