Bachelors Theses and Reports, 1928 - 1970
A sponge spicule is a siliceous or calcareous individual or group of rays which form a framework for the sponge. Sponge spicules are very delicate and easily broken. The methods used in obtaining micro-fossils vary considerably with the type of material from which they are to be recovered and the frailness of the fossil obtained.

A Preliminary Study Of The Micro-Fauna Of Certain Paleozoic Formations Of Montana, George Powe
Bachelors Theses and Reports, 1928 - 1970
The study of the micro-fauna of Montana formations has been almost entirely neglected. Because the petroleum industry of this state has not felt the necessity for using micro-paleontology in its sub-surface correlations, the science has been but little used. The Montana Power Company has had an examination made of some of its well cuttings by a competent micro-paleontologist who found some foraminifera in Mesozoic sediments. However, no investigations have been made to determine the presence and character of the micro-fauna of the Paleozoic formations of Montana.
