Fossil Dinosaur Blue Gem Bone Big Blue 3- Jurassic/Morrison
Big Blue 3 - Rare Blue Gem Bone Slab. Looks as good dry as it does wet. An extraordinary sky-blue or powder blue cell structure depending on how blue your skies are. A few crystal centered, and white agate centered, plus a sprinkling of bright red cells too. At last, we were able to cut this fine specimen!
Just kidding but even with a brand new blade it has taken a while to get these pieces! Shown both wet & dry; a lot of dry shots. This is the third slab from the Mother Specimen and is the heaviest/thickest yet. Four inches Wide front and back.Left Edge: 1.75 Tall. Middle and Main Height: 2.25 inches Tall. Right Edge: TWO inches Tall. Smooth both sides and right edge; thickness goes from 3/16 left edge to 1/4 inch through middle and then to 3/8 inch about an inch into/ from right edge. I've shown it around, and asked some people who see and look at a lot of bone, and they agree 1 it is BLUE, 2 never seen anything quite like it.
Dinosaurs first appeared at the end of the Middle Triassic or in early Late Triassic time, approximately 230 million years ago. The primitive dinosaurs of the Triassic were neither as abundant nor as varied as they would become in Jurassic and Cretaceous times.
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.
