Un'asta decisamente atipica è prevista per il 18 aprile nella Tonhalle di Zurigo. Per la terza volta al mondo e per la prima volta in Europa, sarà venduto lo scheletro di un Tyrannosaurus Rex. Il prezzo di partenza è di 5 milioni di franchi. Il catalogo della casa d'aste Koller indica addirittura una fascia di prezzo fino a 8 milioni.
Lo scheletro del dinosauro, che ha 67 milioni di anni, è lungo 11,6 metri e alto 3,9 metri; chiamato "Trinity", è stato assemblato partendo da tre esemplari diversi portati alla luce tra il 2008 e il 2013 nelle formazioni di Hell Creek e Lance Creek, nel Montana e nel Wyoming, negli Stati Uniti. Solo il 50% delle ossa, però, è originale.
Gli scienziati sono contrari alla vendita, temono che questo li privi di prezioso materiale di ricerca.
