This Spinosaurus aegyptiacus sacral vertebra measuring 175mm was discovered in the Saharan Western desert regions of South East Morocco. The sacrum represents an essential element for understanding the Dinosauria clade, beginning with the first use of the taxon name by Richard Owen in 1841 a five-vertebra sacrum was initially considered diagnostic of sauropods and theropod dinosaur anatomy.

This dinosaur vertebra is from the same fossil horizon where Nizar Ibrahim made a significant Spinosaurid find, in a detective tale which unfolded in the southern part of Morocco. The bones which led to the eventual discovery of a partial skeleton Nizar finally identified in Italy and with the help of Paul Serrano from the museum of Chicago excavated bones to complete a partial skeleton back in Chicago. These bones found on the slopes of the Red Beds Hamada in the western desert. A replica skeleton of that partial skeleton was composited together from bones from various museum sources and went on display at the National Geographic Museum in Washington, D.C., The exhibition of Spinosaurus, Lost Giant of the Cretaceous Period in April 2015. This current exhibit illustrated above was discovered in Morocco between 2013 to 2014 made its way to a European source and was secured later by our fossil team.
