The giant skeleton of TRX-TRINITY will be displayed in the magnificent main lobby of the historic Tonhalle concert hall in Zurich. From late March to mid-April, concert-goers as well as visitors who have reserved time slots will be able to admire the impressive Tyrannosaurus rex in a unique setting on the Lake of Zurich. After the extremely successful first ‘Out of This World’ auction in June 2022, the highly anticipated sequel will take place on 18 April. The ‘Out of This World’ auction at Koller, in which the T. rex Trinity will be offered, presents items from a variety of eclectic fields, including natural history, space exploration and entertainment memorabilia.
The giant skeleton of TRX-TRINITY will be displayed in the magnificent main lobby of the historic Tonhalle concert hall in Zurich. From late March to mid-April, concert-goers as well as visitors who have reserved time slots will be able to admire the impressive Tyrannosaurus rex in a unique setting on the Lake of Zurich. The undisputed star of the auction is the approximately 67-million-year-old TRX-293 TRINITY Tyrannosaurus rex skeleton. For the first time in Europe and only the third time worldwide, a skeleton of an entire T. rex dinosaur of exceptional quality will be offered at auction. Mounted in a dynamic, scientifically accurate and state-of-the-art pose, it is among the finest specimens of one of the largest terrestrial predators ever to inhabit the Earth.
Only 32 skeletons of adult T. rex specimens have been found worldwide
With an astonishing length of 11.6 metres (38 feet) and a towering height of 3.9 metres (12.8 feet), Trinity is one of the most spectacular T. rex skeletons in existence, a well-preserved and brilliantly restored fossil. The more than 50 per cent original bone material comes from three Tyrannosaurus specimens excavated between 2008 and 2013, from the Hell Creek and Lance Creek formations in Montana and Wyoming. Both sites are known for two of the most important Tyrannosaurus discoveries: ‘Sue’, which sold at auction for $8.4 million in 1997, and ‘Stan’, whose world-record hammer price of $31.8 million in 2020 catapulted dinosaur fossil prices into a realm usually reserved for the most sought-after works of art.
Fossils of dinosaurs and other living things have formed over the course of tens of thousands to hundreds of millions of years. This is only possible if the conditions are right – and why fossil finds are so rare. According to the April 2021 scientific journal Nature, only 32 skeletons of adult T. rex specimens have been found worldwide. The rare skeletons of adult T. rex specimens which have been unearthed are almost all now in institutional collections. The Zurich auction is therefore an exceptional opportunity to acquire such a fossil of the highest quality.
The first Tyrannosaurus Rex TRINITY is a remarkable specimen
Each of Trinity’s 293 bones was painstakingly excavated, cleaned and restored before it could be assembled. For an entire dinosaur, this process often takes between seven and ten years – an enormous effort for a team of palaeontologists, preparators and conservators.
Trinity’s rarity and importance is in large part due to its incredibly well-preserved skull, which comes from a single specimen. ‘Dinosaur skulls are very rare; they are among the most valuable components of fossil skeletons’, said scientific advisor Nils Knötschke, one of the world’s leading fossil preparators. ‘In fact, most dinosaurs are found without their skulls. But here we have original Tyrannosaurus skull bones, all from the same specimen’.
‘In all three specimens, the preparation was done very well, and the whole is very well preserved’, said Knötschke. ‘I was particularly surprised that not only the vertebrae, but also the filigree spines of the dorsal and cervical vertebrae are present. The very fine bones from inside the skull are usually lost, and these are also preserved in Trinity’.
‘I was impressed when I saw it, because it all seems to fit together so nicely’, said Dr Hans-Jakob Siber, palaeontologist and director of the Dinosaur Museum in Aathal, Switzerland. ‘It’s one of the most impressive mounts I’ve seen. The quality of the restoration plus the quality of the mount sort of breathes life again into the specimen, which lived millions and millions of years ago. TRX-293 TRINITY would certainly be an astonishing attraction in any museum in the world’.

Auction in Zurich: 18 April 2023
Trinity x Tonhalle
The giant skeleton of TRX-TRINITY will be displayed in the magnificent main lobby of the historic Tonhalle concert hall in Zurich. From late March to mid-April, concert-goers as well as visitors who have reserved time slots will be able to admire the impressive Tyrannosaurus rex in a unique setting on the Lake of Zurich.
The choice of the Tonhalle Zurich as the exhibition venue for TRX-293 TRINTY is particularly appropriate for Cyril Koller, owner and CEO of Koller Auctions: ‘It was in the Kongresshaus, situated in the same building complex as the Tonhalle, where Koller held its very first auction 65 years ago’. Christian D. Link, Head of Department for ’Out of This World’, adds: ‘Exhibiting Trinity in the Tonhalle is in keeping with the spirit of the contemporary cabinet of curiosities. A dinosaur doesn’t have to been shown in a museum, it can also be in an unexpected public space, or even in someone’s home. Items taken out of their traditional context often take on a new and interesting significance’.
The ‘Out of This World’ Auction
The ‘Out of This World’ auction at Koller, in which the T. rex Trinity will be offered, presents items from a variety of eclectic fields, including natural history, space exploration and entertainment memorabilia. What these intriguing natural and man-made objects all have in common is that they constitute a fascinating contemporary cabinet of curiosities. Some highlights include an extremely rare Mars meteorite called ‘The Red Colossus’ (lot 942, CHF 150 000 / 250 000), an Australian gold nugget weighing over 1.6 kilograms (lot 935, CHF 120 000 / 150 000), and a Soviet cosmonaut’s 1980s space suit (lot 911, CHF 65 000 / 85 000).
