Scientists from the University of Bonn are researching which plants giant dinosaurs could have lived off more than 100 million years ago in order to find out how they were able to become as large as they did. Such gigantic animals should not have existed.
Their recipe; take 200 milligrams of dried and ground equisetum, ten milliliters of digestive juice from sheep's rumen, a few minerals, carbonate and water. Fill a big glass syringe with the mix, clamp this into a revolving drum and put the whole thing into an incubator, where the brew can rotate slowly.
In this way they obtained an artificial 'dinosaur rumen'. With this apparatus (also used as a ‘Menke gas production technique’ in assessing food for cows) Dr. Jürgen Hummel from the Bonn Institute of Animal Sciences (Bonner Institut für Tierwissenschaften) is investigating which plants giant dinosaurs could have lived off more than 100 million years ago, since this is one of the pieces still missing in the puzzle involving the largest land animals that ever walked the earth. The largest of these 'sauropod dinosaurs' with their 70 to 100 tons had a mass of ten full grown elephants or more than 1000 average people.
