However, as TWAY& RIEDEL(1991) pointed out, in the absence of a definite taxonomy for a new assemblage of ichthyoliths their descriptor system has its uses.
In the sixties and seventies contributions appeared on all fronts and from new parts of the world and increasingly, in the southern hemisphere -- OBRUCHEV& KARATAJUTE -TALIMAA(1967), MARK -K URIK(1969, 1970; also MARK -K URIK& N OPPEL1970), S CHULTZE(1968, 1969), TURNER(1971-1977), K ARATAJUTE- T ALIMAA(1964, 1968, 1978), M ÄRSS(1979), and the Parisian team (B LIECK& GOUJET1978, GOUJET& B LIECK 1977, 1979, J ANVIER1977, 1978) inspired by either GROSSor ØRVIGor both. Reassessment of older work also began, especially in the northern hemisphere (e.g., ZIDEK1973, ZANGERL1981). They dominated this time principally because they were the only ones investigating these remains.
Only in the late eighties and nineties have we seen almost a revolution in the field. A major effort has taken place in Eastern and Western Gondwana (Australia, Antarctica, China and elsewhere in SE Asia; South America, Africa, Saudi Arabia) (e.g., B OUCOTet al. 1989, GAGNIERet al. 1988-1989, J ANVIER& DE M ELO1987-1992, L ELIEVREet al. 1994, LONG1990, TURNER1982, TURNERet al. 1981, TURNER& YOUNG1987, W ANG1984, W ANG& TURNER1985, W ANGet al. 1986, YOUNG& GORTER1981). New parts of Europe, the eastern former- USSR and North America were also investigated during this time (e.g., HANSEN1986, MADER1986, M ADER& S CHULTZE1987, M AISEY1989, M ÄRSS1986, 1989, P OLTNIG1984, S CHNEIDER1988, VALIUKEVICIUS1979, 1985, 1998, VIETH1980, VIETH-SCHREINER1983).
The resulting cohesion and increase in specialists and numbers of publications available has come about mainly through the auspices of the co-operative research plan devised on the wind-swept hillsides of Yunnan, South China in 1987, during the field trip of the 5th Early Vertebrate Studies Meeting organised by IVPP, Academia Sinica. Alongside this has been the increasing co-operation with conodont, ostracode and laterly, spore workers, which has brought forth a wealth of saved material carefully picked and recorded from conodont residues. These strands were woven together and culminated in the UNESCO-IUGS IGCP 328 Palaeozoic Microvertebrates project which this volume records [We refer the reader to the IGCP 328 final publication list in Appendix 2.]

Marine/Non-marine correlation

M URCHISON(1840, M URCHISONet al. 1845) in his tour of western Europe and Russia was the first to realise that the presence of certain fish dominated the Old Red Sandstone and that study of these fossils could aid biostratigraphy. A century later, SÄVE -SÖDERBERGH(1941) published a benchmark paper in which he attempted to gain a stricter biostratigraphical control and tighter terminology of Palaeozoic vertebrates. S ÄVE-S ÖDERBERGH would undoubtedly have been a candidate for IGCP 328 in his time! The first fish-based biostratigraphical scale was defined in the North Atlantic region by Errol I. W HITE(1938-1961), using the pteraspid heterostracans for the first biozonation of the Lower Old Red Sandstones of England (STUBBLEFIELD1985). WESTOLL(1979) summarised the state of the art for Devonian fish biostratigraphy in 1979 presaging the work on microvertebrates to come.
