Adapidae (suborder Strepsirrhini (or Prosimii), infra-order Lemuriformes) An extinct family of lemur-like animals; most were small, but a few had heads 10 cm or more long. The brain case was small with temporal crests and smooth cerebral hemispheres, and the tympanic ring was included in the bulla. Dentition was full and the incisors were not procumbent, but in Adapis species the canines were incisiform, the molars resembling those of some modern lemurs. The skeleton was adapted for grasping, leaping, and perching. Old World adapids (e.g. Adapis and Pronycticebus) probably resembled lemurs and lorises, to which they may be ancestral. They were distributed in Europe and N. America in the Eocene.

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.
