Soft tissue and cartilage have usually decayed entirely. Due to many influences, what is found is never an exact image of the living animal. Bone CountĪ long time has passed between the death of an organism and the discovery of its fossilised remains. These finds tell us that at the lifetime of Tristan Otto, the climate was humid, warm and temperate. It is rich in dinosaurs as well as remains of other animals and plants. The well-known formation contains deposits beginning at 67 million years ago and ending approximately 65 million years before our time. Tristan Otto’s bones were found in the Hell Creek Formation, which runs through Montana, North and South Dakota in the USA. Thus, it took until October 2012 until the skeleton was recovered. However, soon after his discovery, he fractured his ankle, and in the following season 2011, he was hampered by a shoulder injury. Craig immediately realised that this was a T yrannosaurus rex. On one of his treks in 2010, he discovered part of a pelvic bone protruding from the ground. Craig Pfister spends this time on site, sleeping in tents and either excavating or going for long treks in search of promising sites.
He has found several Tyrannosaurus specimens.ĭue to the long cold winters, excavation can only take place from the end of March to late October. With the permission of land owners, he mainly excavates dinosaurs in Montana.

DiscoveryĬraig Pfister is a professional fossil excavator and palaeontologist. At the same time, all presentations and information that have been collected about the animal add to its value – in every sense of the word.
Tristan Otto is an example of a solution to the problem. Museums, on the other hand, do not have the means to cover the cost for salvaging and preparing such a find. With the purchase, many precious specimens become unavailable to research. The Tristan Otto agreement shows a way out of a dilemma much criticized by scientists – the purchase of fossils and artefacts by private individuals.

Therefore it seemed to me to be the perfect place for Tristan Otto.” “The Museum für Naturkunde Berlin is one of the world’s leading museums with outstanding exhibitions and research, particularly regarding dinosaurs.

It is among the best-preserved Tyrannosaurus rex specimens worldwide.
