faecal pellet

faecal pellet Rounded, initially soft particles, mostly 100–500 μm in diameter, which are excreted by organisms. The internal structure of the pellet is usually fine grained. Worms (Annelida), gastropods, and crustaceans produce these pellets in large quantities. Faecal pellets are most likely to accumulate and be preserved in low-energy, muddy environments colonized by an abundant fauna, e.g. lagoons and tidal flats. As a type of fossil excreta, the term is commonly applied to small droppings, often of invertebrate origin, which may make up important parts of some lithologies. See COPROLITE.

Learn more about citation styles

Citation styles gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, cannot guarantee each citation it generates. Therefore, it’s best to use citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:

  • Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
  • In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
