But is presenting papers the sum of all they are going to accomplish in the seminar? I got the impression they were going to round-table the issues to come up with an integrated approach.
Keep in mind that this is apparently a very large conference with many simultaneous events - I haven't looked through all of them to find a scheduled roundtable on pre-Cambrian fossils per se, but if you want to look, the full schedule of events is here - discussions and roundtables and cocktail hours and dinner dances and so forth are probably all going to be under the "Other Daily Events" column on the right side of the page...
Presenting papers is propably the sum of it. Usually, at these meetings, important topics will warrant a panel discussion with audience participation.
