ABSTRACT
Thomas, F.C. and Murney, M.G. 1985. Techniques for extraction offoraminifers and ostracodes from sediment samples. Can. Tech.Rep. Hydrogr. Ocean Sci. 54: vi + 24 p.
Several methods of disaggregating sediment samples for analysis of
shelly microfossils, such as foraminifers and ostracodes, are regularly
used at the Atlantic Geoscience Centre, Bedford Institute of Oceanography,
Dartmouth, N.S. This paper describes and illustrates these methods, with a
view towards instructing the inexperienced student in their uses. Also
included are a brief source list for materials, and a selected bibliography
of publications dealing with these and other techniques.

A l'Institut Oc~anographique de Bedford, Dartmouth, N.E., les
chercheurs du Centre G~oscientifique de l'Atlantique emploient reguliere-
ment plusieurs m~thodes pour d~sagreger les ~chantillons de s~diments
utilis~s pour l'analyse des microfossiles coquill~s tels que les foramini-
f~res et les ostracodes. Cette publication d~crit et illustre ces
m~thodes, dans Ie but de les enseigner aux ~tudiants sans exp~rience. Y
sont joints ~galement une breve liste de mat~riaux et une bibliographie
s~lectionn~e des publications traitant de ces techniques ainsi que

AUTHORS' NOTE
What motivates the compilation of another processing techniques
paper? It is the authors' belief that there is a need for a small,
portable compendium of these methods.
Textbooks presently used in university micropaleontology courses
often contain an overall survey of these techniques, but do not offer the
student the clear step-by-step directions often needed in laboratory work.
This handbook has been written with a view towards guiding even the most
inexperienced student safely through the steps involved with a minimum of
problems.
Common sense, of course, is an important ingredient in any labora
tory work, and the users of this manual will, with practice, soon find the
most efficient way to do a given procedure, saving time and effort along
the way.
The authors wish to encourage readers, to experiment on their own
with processing techniques and would like to hear about any improvements or
variations of these methods or any others which prove successful, so that
they may be included in a later edition of this work.
The thought that provoked the authors' participation in this
project is that nothing is absolute and it all needs revisions time and
time again. We only hope to promote a more conscious attitude in your
approach to 'day to day' routine.
Finally, the authors wish to express appreciation to F.M.
Gradstein, A.G.C., for many useful suggestions during the compiling of this
manuscript, and to F.E. Cole and M.A. Williamson, both of A.G.G., for
critically reviewing the final text. G. Cook, A.G.C., vastly improved and
