10^th ISC 2017 Logo explanation:

The 10^th ISC Logo is composed of selected elements of the Viennese skyline with, from left to right, the Stephansdom (St. Stephen’s Cathedral), the Wiener Rathaus (city hall), the Wiener Riesenrad (big wheel) and the Donauturm (Danube Tower). The star-shaped nannofossil in the big wheel is the plan view of a large form of the Coniacian to Campanian coccolith Lithastrinus grilli Stradner, 1962 (gen. et sp. nov.) in ‘Upper Cretaceous stratigraphic colour’, used here in honour of the renowned Austrian micropaleontologist Herbert Stradner (born 1925). The clouds comprise of elements of the suture of the Cenomanian to Turonian ammonite Spathitoides sulcatus Wiedmann, 1960 (after Kennedy, Wright and Hancock,1980). The text is in ‘Lower Cretaceous stratigraphic color’.
