However, as TWAY
& RIEDEL (1991) pointed out, in the absence of a definite taxonomy for a new assemblage ofBRUCHEV 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 -- O & KARATAJUTE -TALIMAA (1967), MARK -K URIK (1969,ARK -K URIK 1970; also M & NOPPEL 1970), SCHULTZE (1968, 1969), TURNER (1971-1977), KARATAJUTE- TALIMAA (1964, 1968, 1978), MÄRSS (1979), and the Parisian team (BLIECK & GOUJET 1978, GOUJET & BLIECK 1977, 1979, J ANVIER 1977, 1978) inspired by either GROSS or ØRVIG or both. Reassessment of older work alsoIDEK began, especially in the northern hemisphere (e.g., Z 1973, ZANGERL 1981). They dominated this timeOUCOT 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 et al. 1989, GAGNIER et al. 1988-1989, JANVIER & DE M ELO 1987-1992,ELIEVRE L et al. 1994, LONG 1990, TURNER 1982, TURNER et al. 1981, TURNER & YOUNG 1987, WANG 1984,ANG W & TURNER 1985, WANG et al. 1986, YOUNG & GORTER 1981). New parts of Europe, the eastern former-ANSEN USSR and North America were also investigated during this time (e.g., H 1986, MADER 1986, MADER &CHULTZE S 1987, MAISEY 1989, MÄRSS 1986, 1989, POLTNIG 1984, SCHNEIDER 1988, VALIUKEVICIUS 1979,IETH 1985, 1998, V 1980, VIETH-SCHREINER 1983).
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.]
(1840, MURCHISON et al. 1845) in his tour of western Europe and Russia was the first to realise thatÄVE -SÖDERBERGH the presence of certain fish dominated the Old Red Sandstone and that study of these fossils could aid biostratigraphy. A century later, S (1941) published a benchmark paper in which he attemptedÄVE-S ÖDERBERGH to gain a stricter biostratigraphical control and tighter terminology of Palaeozoic vertebrates. S 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. WHITE (1938-1961), using the pteraspid heterostracans forTUBBLEFIELD the first biozonation of the Lower Old Red Sandstones of England (S 1985). WESTOLL (1979) summarised the state of the art for Devonian fish biostratigraphy in 1979 presaging the work on microvertebrates to come.
