On 13th of January 2016, Michael E. Schudack passed away suddenly at the age of 61. The micropalaeontological community, his colleagues, companions, disciples, and students grieve for a dedicated geologist, micropalaeontologist (focus Charophyta, Ost racoda) wholehear tedly, distinguished stratigrapher, enthusiastic Earth history specialist, and exceptionally gifted teacher – and a mentor and friend. Michael E. Schudack is survived by his wife Dr. Ulla Schudack and his daughter Lisa Schudack to whom we would like to express our deepest sympathy.

Michael E. Schudack was born on 9th of August, 1954 in Gelsenkirchen (Ruhr Metropolitan Region, North Rhine-Westphalia), Germany. He studied Geology and Palaeontology at the ‘Ruhr-Universität Bochum’, which he finished in 1979, and also received his doctorate from this university in 1985. His doctoral thesis ‘Die Charophytenflora und fazielle Entwicklung der Grenzschichten mariner Jura/Wealden in den nordwestlichen Iberischen Ketten (im Vergleich zu Asturien und Kantabrien [Charophyte flora and facies development of the marine Jurassic/Wealden boundary layers in the Northwestern Iberian Ranges (with a comparison to Asturia and Cantabria)]’ was supervised by Hans Mensink and published in 1987 (Schudack, 1987b). In 1988, he took up a fixed-term position at the ‘Freie Universität Berlin’, Germany, where he deepened his knowledge on charophytes and where in 1993 he received his post-doctoral lecture qualification (‘Habilitation’ in German speaking countries) with his habilitation treatise ‘Die Charophyten in Oberjura und Unterkreide Westeuropas. Mit einer phylogenetischen Analyse der Gesamtgruppe [The charophytes of the Upper Jurassic and Lower Cretaceous of Western Europe. With a phylogenetic analysis of the whole group]’ (Schudack, 1993).

From 1995 to 1998 he was Staff scientist at the ‘Martin Luther-Universität Halle-Wittenberg (Saxony-Anhalt, Germany)’. In 1998 he returned to the ‘Freie Universität Berlin’ to take up a position as ‘Akademischer Rat’ (Lecturer). In 2002 he was appointed ‘Akademischer Oberrat’ (Senior Lecturer). In 2005, the ‘Mar t in Luther Universität Halle-Wittenberg’ awarded Michael Schudack the honorary professorship.

Michael Schudack was an enthusiastic geologist, palaeontologist and Earth history specialist with emphasis on micropalaeontology (Ostracoda, Charophyta), biostratigraphy, palaeobiogeography, palaeoclimatology, palaeoecology, general Earthhistoryandstableisotope geochemistry. He excelled in that his work was characterized by broad integrated approaches that were based on solid fundamental research and interdisciplinary methodology. Michael Schudack always kept the big picture in mind, an important aspect that he conveyed to his students and disciples. His scientific work comprises more than 80 peer-reviewed articles, book chapters and monographies that cover a broad range of topics, not to mention numerous abstracts and editorial works. Charophytes, par t icular ly Mesozoic charophytes, their taxonomy, phylogeny, palaeobiogeography and biostratigraphy, were Michael Schudack’s first professional passion, one of his main scientific focuses ever since his doctoral thesis (Schudack, 1987b), and one of the fields in which he achieved ground-breaking scientific progress. His first own project sponsored by the German Science Foundation (DFG Schu 694/1-1, 1989–1992) was on t he ‘Biostratigraphy and palaeoecology of charophytes from the Upper Jurassic of northwest Germany’ (e.g. Schudack, 1990, 1991; Feist and Schudack, 1991) and culminated in his habilitation treatise (Schudack, 1993a). His works on the 11/53 charophytes of the Upper Jurassic and Lower Cretaceous, particularly those from the Lower Saxony Basin where he developed a new local biozonation, later entered into the European Mesozoic–Cenozoic charophyte biozonation of Riveline et al. (1996).

Michael Schudack’s contributions to charophyte palaeontology are numerous and considerable. His general interest in the application of new examination and imaging methods and techniques (e.g. Mehl and Schudack, 1991) promoted his research. For example, Michael Schudack had a sixth sense to discover the minute and elusive basal plates of a number of important Mesozoic charophytes, such as Porochara, Feistiella or Mesochara. This was extremely helpful in elucidating their systematics and phylogeny. In addition, he disentangled the complicated utricle s t ruc ture of the ear l iest c lavatoracean Echinochara. Beyond that, he also excelled in the regional and supraregional biostratigraphical analysis of charophytes from the Upper Jurassic, a difficult time interval in which to undertake such a work, due to the abundance of the less informative gyrogonites of the porocharaceans and early characeans.

Michael Schudack’s second micropalaeontological focus was on ostracods. Early in his career he had started to integrate the taxonomically substantiated appl icat ion of ost racods to support his bios t rat igraphi cal and palaeoecologi cal interpretation of marginally marine to non-marine Mesozoic successions. His work on ostracods – includingtaxonomy, biostratigraphy, palaeogeography, palaeoecology, and geochemistry – was promoted through the productive collaboration with his wife, the geologist and ostracodologist Dr. Ulla Schudack, to whom he was married since 1982.

Michael Schudack’s earlier post-doctoral works culminated in his German Science Foundation project ‘The ostracods and charophytes of the Morrison Formation (Upper Jurassic of Colorado and Utah, United States)’ (DFG Schu 694/4-1, 1992–1994), in the context of which he conducted quantitative analyses and could establish biogeographical and biostratigraphical links between the Colorado Plateau and western and central Europe based on thorough taxonomical and paleobiogeographical analyses. Through modern taxonomic revision and based on his experiences, one groundbreaking outcome of his work was that Michael Schudack could demonstrate that North American and European non-marine Upper Jurassic deposits have ostracod species (Cytheroidea and Cypridoidea) in common (Schudack, 1995b, 1996c, 1999a; Schudack et al., 1998), an aspect that previously had only rarely been speculated about.

Michael Schudack soon established himself an international reputation in both the international charophyte and ostracod community. In 1991 he organized the meeting of the Group of European Charophyte Specialists (GEC) in Berlin. From 2001–2004 he was secretary of the International Research Group on Charophytes (IRGC). In 2005, Michael Schudack organised the successful 15th International Symposium on Ostracoda in Berlin, Germany (see Program and Abstract volume under: http://www.geo.fu-berlin.de/geol/fachrichtungen/pal/eigenproduktion/Band6.pdf), the proceedings of which were published as special issues of three journals (http://www.ostracoda.net/meetings/12-meetings/iso-meetings/9-15th-iso-berlin-2005-germany). At this meeting, he was elected secretary of the International Research Group on Ostracoda (IRGO) for the period 2005–2009. For many years he also was project reviewer for the German Science Foundation (DFG).

Michael Schudack’s third micropalaeontological main field of interest was Paleogene foraminifers. This focus was largely related with his extensive works (together with K. Nuglisch) on the borehole Loburg 1/90 (Saxony-Anhalt, Germany) core and started with his German Science Fund project ‘Biostratigraphy and isotope geochemistry of benthic Foraminifera from the Upper Eocene and Lower Oligocene of the eastern North Sea Basin (borehole Loburg 1/90, Sachsen-Anhalt)’ (DFG Schu 694/7-1, 1996–1999) and was continued by another project ‘Planktonic foraminifers, biostratigraphy and palaeoclimatology around the Eocene/Oligocene boundary of the Loburg 1/90 borehole (Saxony-Anhalt)’ (DFG Schu 694/23-1, since 2011). From these derived numerous publications successively describing the benthic, agglutinating and planktonic foraminifers from this core as well as their biostratigraphy and isotope geochemistry (Schudack and Nuglisch, 2000, 2004, 2005, 2006, 2007, 2013).

During that time (2004–2007) Michael Schudack was also secretary of the ‘Subkommission für Jurastratigraphie’ (Subcommission for Jurassic Stratigraphy of the Germans peakingarea) and 2005–2007 Corresponding Member of the International Subcommission on Jurassic Stratigraphy – the Jurassic Earth history, regional geology, stratigraphy and palaeoclimatology was another of his research focuses. In this field, Michael Schudack focused on regional aspects of the Central European (Germany and adjacent areas) Jurassic (e.g. Gramann et al., 1997; Pienkowsky and Schudack, 12/53 2008a; Schudack and Tessin, 2015) while he continued his works on Jurassic ostracods and stratigraphy of Central Europe and the Iberian Peninsula in close collaboration with his wife Ulla Schudack (e.g. Schudack, 2000a, b; Schudack, M. and Schudack, U. 1995a, b, 1997, 2011; Schudack, U. and Schudack, M., 2000, 2002, 2009a, b, 2012). In the supraregional to global context and as based on his charophyte, ostracod, and foraminifer isotope geochemistry works (supported by German Science Foundation project ‘Isotope geochemistry of Foraminifera, Ostracoda, and Charophyta – a contribution to the late Jurassic palaeoclimate’, DFG Schu 694/11-1; 1998–2000), Michael Schudack published significant contributions to (mainly Upper) Jurassic palaeoclimatology (e.g. Schudack, 1996c, 1999; Pienkowsky and Schudack, 2008b).

In the early 2000s Michael Schudack extended his range of research fields to Quaternary non-marine ostracods, palaeoenvironments and palaeoclimate on the one hand, as well as (Lower) Cretaceous non-marine ostracods on the other hand. The former arose from his German Science Foundation project ‘Micropalaeontological and geochemical investigations of the palaeoenvironment and palaeoclimate of the Qaidam Basin (NW China) during the late Cenozoic’ (DFG Schu 694/13-1 and 13-2, 2000–2003), from which arose a number of publications with his PhD student Steffen Mischke (e.g. Mischke et al. 2002, 2003, 2004, 2005; Mischke and Schudack, 2001). The latter developed from different side projects Michael Schudack conducted with, among others, his wife Ulla Schudack (e.g. Luger and Schudack, 2001; Schudack, M. and Schudack, U. 2002; Schudack and Sames, 2003; Luppold et al., 2005; Khand et al., 2007) – thereby further extending his geographic working areas to Asia, Africa and the southern hemisphere – and from the German Science Foundation project ‘Ostracods and charophytes f rom the nonmar ine Lower Cretaceous of the western United States – biostratigraphy, palaeoecology, biogeography, and phylogeny’ (DFG Schu 694/14-1 and 14-2, 2003–2007) together with his PhD student Benjamin Sames (e.g. Sames et al., 2010a, b). Here as well, it was Michael Schudack’s trademark being able to contribute constructive to groundbreaking ideas and hypotheses that derived from his broad and deep holistic understanding of general Earth history, geology, stratigraphy, palaeontology and palaeoclimatology, a knowledge he freely shared with colleagues and students.

Aside from his main focuses described above, Michael Schudack worked on topics in the context of Devonian and Triassic geology of Germany including bio-, litho-, and sequence stratigraphy (e.g. Schudack, 1993c, 1996d).

Very recently, Michael Schudack increasingly placed his focus on charophytes again (e.g. Blindow and Schudack, 2014; Schudack, 2016) and extended his field of activity back into the Paleozoic based on a new German mScience Foundation project he just had started in 2015 (‘Revision of the Paleozoic charophytes of Germany – with contributionsm tosystematics, phylogenyand  palaeoecology’, DFG Schu 694/25-1).

Most notably for his colleagues and students, Michael Schudack was an approachable, friendly, communicative and modest man, who also had a likeable, relaxed manner. He was both a gifted teacher and a dedicated field geologist who could easily inspire his audience in the lecture hall as well as in the field, and was likewise popular and respected among his colleagues and students. One got the notion that he based his dedication on the motto ‘teaching is the best way to broaden my horizon’. In dealing with his Master and PhD students, Michael Schudack was friendly and open. He never wanted to put himself in the centre of attention with respect to their scientific results and, for example, the order of authors in publications, but selflessly supported his students in getting and taking credit for their achievements and promoting their scientific development and career. At Palaeontology at the Institute of Geological Sciences of the ‘Freie Universität Berlin’, he showed great commitment in curating the teaching collection over many years (cf. Schudack, 2002). Within the scope of the geology party of the Department of Earth Sciences the students had just recently presented Michael Schudack with the Teaching Award in December 2015.

Michael Schudack was a music lover and had a close affinity to nature. Among his private passions were ornithology, motorbike riding, and dendrology. The latter two hobbies he combined over many years in that he drove by bike through central Europe purposefully visiting ancient trees, many of these being natural monuments, of which he took pictures with himself and his bike, which he then catalogued in photo albums. One of these photos has been included here because it well depicts Michael Schudack as he was and as we remember him.

With Michael E. Schudack we have lost a highly valued colleague and mentor – but above all we miss a good friend.
