This is a Spinosaurus vertebra. The fossil comes from the Cretaceous sediments of Taouz in Morocco.
The vertebra is unbroken and completely preserved, it measures approximately 10 x 9 x 6.5 cm.
As a small addition, a piece of a rib is still preserved on the vertebral body.
Great piece without any manipulations!
