Fossil Dinosaur Blue Gem Bone Big Blue 2- Jurassic/Morrison Formation

Big Blue Two- Rare Blue Gem Bone Slab. Sky blue cells with chocolate webbing. Has a few bright red cells and a few white agate cells with crystal centers. Big cells with unusual shapes.

For some reason, the water pools up on the slab, inspite of rinsing it with dawn dish soap to remove the cutting oil. We've shown it around to our bone friends and no one has seen anything quite like it, and they are jewelers that go to many shows. 4 to 4 1/8 inches Wide X 1 3/4 inches tall (left edge) to 2 1/4 middle/most of piece to 1 3/4 Tall right edge. The piece is a uniform 1/4 inch THICK.

It has two straight edges with the left edge polished smooth. Utah is the site of the earliest Morrison dinosaur discovery, Dystrophaeus viaemalae, a sauropod dinosaur discovered on the 1859 Macomb Expedition to southeastern Utah.

Although Utah is most famous for its Morrison Formation dinosaur fauna, Utah has a prolific fossil record that spans the entire Age of Dinosaurs. The dinosaurs thrived for over 150 million years. The fluvial (stream-deposited) sediments of the Morrison Formation dominated the Upper Jurassic landscape of eastern Utah.

Originating approximately 150 million years ago as floodplain deposits, the Morrison Formation is exposed throughout the Colorado Plateau, including Colorado, Wyoming, eastern Utah, northern New Mexico, parts of Montana and South Dakota, and the panhandle of Oklahoma. The well-known Morrison dinosaur fauna includes Utah's official state fossil, the meat-eating theropod Allosaurus ; other theropods, including Ceratosaurus, Stokesosaurus, and Marshosaurus; the sauropod dinosaurs Apatosaurus (commonly known as Brontosaurus), Camarasaurus, and Diplodocus ; and the ornithischians Camptosaurus, Dryosaurus, and Stegosaurus.
