Sažetak
This year (2018) we celebrate the 20th anniversary of the publication the 'Larger foraminiferal biostratigraphy of the Tethyan Paleocene and Eocene' by Serra-Kiel and co-authors (1998), well-known for introducing 20 SBZ (= Shallow Benthic Zones), ranging from K/Pg boundary up to the Eocene/Oligocene boundary. This standart Paleogene biozonation is based on 400 index taxa of alveolinids (99), nummulitids (120), assilinas (41), orthophragminids (71), agglutinated species (14), porcelaneous species (24) and hyaline species (31) and is widely used from the Western Mediterranean Neo-Tethys to Assam and Tibet. The present work focusses on the alveolinids of the Adriatic region, from the outcrops in the NW (Mt. Lessini, Friuli, Karst, Istria) towards the SE (Dalmatia, Herzegovina) and the Gargano Peninsula in Italy. It is based on various studies on alveolinids by K. Drobne et al. (2009), by H. Ibrahimpašić (2012) and on unpublished work on the assemblages of NE Italy. According to the data of Hottinger (1960) for the N and NE Italy, we prepared a table of revised species for the SBZ 4, SBZ 11, SBZ 12, SBZ 13, SBZ 14 and SBZ 17. 25 species are recorded, out of which 7 were described by G. Checchia–Rispoli and 8 by L. Hottinger. K. Drobne (1977) the 'Hauptalveolinenkalk' of G. Stache on the Karst, Čičarija, Istria and Kvarner areas. 94 species of Alveolina have been recorded, of which 23 were described first from this region, including A. laxa Hottinger and A. triestina Hottinger. The alveolinids were collected from 20 key- sections and outcrops, and possess index value for the Thanetian-Bartonian interval on the chronostratigraphic scale (Serra-Kiel et al., 1998). The same assemblages also occur in Dalmatia and Herzegovina (Drobne et al., 2011). As a side issue, and with a global perspective, we also plan a digital update (1998-2018) to the 'Paleogene Larger Foraminifera – Reference List' by J. Pignatti (1998). This publication, listing 4770 works dealing with Paleogene larger foraminifera, is also celebrating its 20th anniversary. We maintain that an update will be useful to larger foraminiferal workers worldwide.
