PLAIN LANGUAGE SUMMARY:
The name "thecamoebian" is applied, as a matter of paleontological convenience, to several not truly related kinds of microscopic, single-celled animals with a simple test (shell or covering) that may be chitinous, calcareous, siliceous, or formed of agglutinated foreign particles. The test is commonly a single-chambered, saclike or saucer-shaped body, rarely with spinelike protuberances. They are found mainly in fresh water, on mosses, or in damp soil. Most of the reported fossil occurrences are in Quaternary sediments, but some are in Tertiary, Mesozoic and Paleozoic rocks. There are some illustrations at http://www.wf.carleton.ca/Museum/arcellacea/3plates.html
The literature on this group is scattered, much of it in obscure publications, and this bibliography is presented as a tool to assist researchers.
