Gorgosaurus’s last meal.  The fossil with preserved stomach contents

The perfectly preserved fossil remains of Gorgosaurus were found in 2009 at Dinosaur Provincial Park in southern Alberta, Canada. The fossils belong to the species Gorgosaurus libratus. It is a representative of the dinosaur family. These creatures roamed western North America about 76 million years ago. From its teeth to the tip of its tail, it can reach nine meters in length and can weigh around three tons.

However, the bones found belonged to a much younger individual. Scientists estimate that he may have weighed around 350 kg and was probably between five and seven years old at the time of his death. This corresponds to adolescence in humans, says Darla Zelenitsky of the University of Calgary, lead author of the study that appears in the journal Science Advances (DOI: 10.1126/sciadv.adi0505).

In the gut of Gorgosaurus, researchers discovered the four hind legs of a small dinosaur. This is the first fossil of a representative of the dinosaur family that has been found with preserved stomach contents.
