The 35th IAS (International Association of Sedimentologists) annual meeting will be held in the Czech republic for the first time in entire IAS history. The Institute of Geology of the CAS participates in its organization. The meeting will be held in the Vienna House Diplomat Prague hotel on June 22–24, 2021.  The total number of participants is expected between 700–1000 including leading scientists in the field of sedimentology.  
Key themes and special sessions cover different processes leading to the origin of sedimentary rocks. Modern approaches and methods will be discussed which study sedimentary rocks as archives recording environmental changes in geological past, however, with implications for the present. All information is available at the Meeting website.

A new publication describes the first and the only articulated fossil specimen of tubeshoulder fish of the family Platytroctidae (order Alepocephaliformes). This remarkable fish inhabits deep-water environment and the specimen described has been found in the Menilitic Formation deposits (Oligocene) exposed in the vicinity of Kelč (Moravia). The specimen is housed in the collection of the National Museum in Prague. The fish represents a new genus and species. Its scientific name Vachalia moraviensis honours the outstanding Czech graphic and painter Josef Váchal, who died fifty-one years ago.

A conclusion on the presence of Ordovician rocks was expressed by the group of Indian geologists co-operating with ichnologist Radek Mikuláš of the Institute of Geology, Czech Academy of Sciences. The Lesser Himalaya mountain belt has been as yet considered to be built from Proterozoic and earliest Palaeozoic (Cambrian) rocks. However, newly collected rich assemblages of trace fossils (i.e., traces after activity of invertebrate organisms) contained in certain portions of the tectonically isolated block of the Nigali Dhar Valley contain trace fossils from the so-called Cruziana rugosa Group, which are considered typically Ordovician in age. They have been reported from epeiric seas of the former Gondwana Supercontinent. The finds, therefore, represent evidence of prolongation of the Ordovician Gondwana sea to the Indian continental tectonic plate.
