Z. Johanson is working on 1995 IGCP 328 Arctic Canada Field Meeting samples that she collected on Prince of Wales Island. She attended the Society of Vertebrate Paleontology meeting in Salt Lake City and later presented an invited talk at the University of Alberta, Edmonton, Canada, entitled "Studies on Australian fossil placoderm and sarcopterygian fishes." R. Parkes (MUCEP) is helping to prepare and sort the 1995 samples and is comparing material with samples from the Lower Devonian of Nevada (M. Murphy coll.). He has visited Dr. L. Jeppson (Lund Univ.) this year to work on Silurian conodonts. S. Turner submitted a manuscript to J. Paleontology on Lower Silurian (Aeronian) thelodonts from Wisconsin and Michigan, U.S.A., in conjunction with D.C. Clark and J.J. Kuglitsch (Univ. of Wisconsin-Madison). This assemblage has elements in common with one from Québec (Turner and Nowlan 1995). New material collected from the field locality in Door County, WI, in May 1997 is being prepared and studied. With James Savelle (McGill Univ., Canada) she is writing a paper on material from the Late Silurian of Somerset Island, Arctic Canada, especially thelodonts (Turner 1997). She is also preparing a manuscript in conjunction with M. Ginter (Poland) on a Late Devonian, early Famennian microvertebrate sample from Melville Island, Arctic Canada, especially phoebodont shark teeth (e.g. Turner in Harrison ed. 1995, Ginter and Turner 1997 at St. Petersburg meeting) and comparative taxa worldwide.
B. Hunda's thesis concerns Ordovician/Silurian trilobites, while K. Soehn continues his thesis and related work on Silurian heterostracans and vertebrate biostratigraphy, both theses based on the Avalanche Lake sections. Soehn, Wilson, and Hanke collaborated with T. Märss, Estonia (Soehn et al. In press) on a study of the vertebrate biostratigraphy of the Avalanche Lake sections, and Soehn and Wilson collaborated with T. Märss on a comparison of the Wenlockian sections at Avalanche Lake and Baillie-Hamilton Island (Märss et al. 1998). G. Hanke's thesis concerns chondrichthyan, acanthodian, and thelodont microvertebrates and the same taxa known by articulated skeletons from the Lochkovian fish locality at 'MOTH'. G. Hanke and M. Wilson attended the Warsaw meeting of IGCP 406 (Ginter and Wilson 1998), where they both presented papers (Hanke and Wilson 1998, Wilson and Hanke 1998) at the workshop on early chondrichthyan fossils. Later they attended the Society of Vertebrate Paleontology meeting in Salt Lake City, U.S.A., where Hanke presented a platform paper (Hanke and Wilson 1998) on acanthodian and chondrichthyan scales and spines, while Wilson gave a plenary talk on the origin of paired fins of gnathostomes (Wilson 1998). Hanke and Wilson both collaborated with P.-Y. Gagnier (Gagnier et al. 1998) for the Warsaw meeting on a new acanthodian from the 'MOTH' locality (manuscript for submission to Acta Geologica Polonica). All of these studies include material collected during the 1996 IGCP 406-related field work at the 'MOTH' site. C. Burrow and Z. Johanson (Australia) both visited Edmonton where they examined specimens of acanthodians, chondrichthyans, and placoderms from the 'MOTH' locality. A major paper describing a new order of vertebrates with thelodont squamation was published this year (Wilson and Caldwell 1998). M. Caldwell and Wilson also contributed to an abstract (Märss et al. 1998) and a journal paper (Märss et al. 1998) on Silurian and Lower Devonian microvertebrates from Baillie-Hamilton and Cornwallis Islands, northern Canada. Caldwell has recently taken a position as vertebrate paleontologist with the Museum of Nature, Ottawa. R. Thorsteinsson continues to work on his monographic study of Canadian Arctic heterostracans. D. Elliott (U.S.A.) has recently joined this project as a collaborator.
