North Africa, early Cretaceous (Lower Albian to Lower Cenomanian), ca. 112 to 97 million years ago. A fossilized vertebra bone from the dinosaur Spinosaurus.

The vertebra is mounted on a custom metal stand for display. Size: 3.5″ L x 2.25″ W x 5.8″ H (8.9 cm x 5.7 cm x 14.7 cm); 9.75″ H (24.8 cm) on included custom stand.
