                    CNIDARIA & PORIFERA

                       Madrid, Spain

                   September 12-15, 1995

             First Circular and Call for Papers

Scientific Topics

           Symposium themes were selected mainly from topics
of proceding  symposiums. Some other topics will be included
in Madrid for the first time. Each session will be opened by
an invited lecture, and volunteered papers will follow. Some
free-papers sessions will be included in the afternoons. The
selected topics are:

     1. Paleobiology of Cnidaria
        (Functional morphology, ontogeny, taxonomy,
        intraspecific variability, etc.)

     2. Paleobiology of Porifera
        (Functional morphology, ontogeny, taxonomy,
        intraspecific variability, etc.)

     3. Biomineralization, microstructures and diagenesis
        of Cnidaria and Porifera

     4. Origin and evolution of Cnidaria and Porifera

     5. Development of Cnidaria and Porifera in nonreef

     6. Development of Cnidaria and Porifera in reef

     7. Taphonomy of Cnidaria and Porifera

     8. Biogeography

     9. Cnidaria and Porifera in biosedimentary process

Oral Presentations

             Space  constraints make  oral presentations are
preferable to poster communications. English is the official
language of  the Symposium.  Each speaker  will be  given 15
minutes  for  presentation  and  5  minutes  for  discussion
(invited speakers  will have  more  time).  Two  35mm  slide
projectors and  one overhead  transparency projector will be
available in  each meeting  room.  VCR  monitors  for  video
presentations will  be available  upon request.  As many  as
three simultaneous sessions are expected.

Poster Presentations

          Poster exhibitions will run concurrently with oral
presentations. Some  poster boards  will  be  available  for
poster displays.  Information about  the physical  layout of
the poster sessions will be included in the second circular.


          The proceedings of the Symposium will be published
in a  volume of  the Boletin de la Real Sociedad Espanola de
Historia Natural. All participants are invited to submit one
or  more   manuscripts  in   English.  Manuscripts  must  be
submitted to  the editor  of the  proceedings at the time of
the symposium.  Guidelines to  authors will be in the second

Field Excursions

          Five filed trips (listed below) will be offered to

cost, duration, accomodation and leadres will be provided in
the second circular.
