The Palaeontological Institute and Museum, University of Zürich (PIMUZ) enabled H.F. to conduct systematic prospecting and numerous excavations near Davos. The government of Canton Graubünden, the municipality of Davos, and the Bündner Naturmuseum in Chur gave permission for the excavations and financial support. Max Kuhn (Uster) provided generous financial support for the preparation of the specimens by C.O. B.M. and L.Ca. also thank the Département de la culture et du sport de la Ville de Genève for a financial support for computer facilities, and Philippe Wagneur (Natural History Museum of Geneva) for assistance to produce the CT scan movie. We thank Anne Kemp (Griffith University) and Mélanie Debiais-Thibaud (University of Montpellier) for discussion. This paper is a contribution to the project “Evolutionary pace in the coelacanth clade: New evidence from the Triassic of Switzerland” supported by the Swiss National Science Foundation (200021-172700) by L.Ca.
