Noun[edit]
placentation (countable and uncountable, plural placentations)
- (biology) The local fusion of the embryonic stage of an animal to its parent for physiological exchange to promote the growth and development of the young; involves a placenta in non-egglaying mammals.
- 2004, “Placentation in species of phylogenetic importance: the Afrotheria”, in Animal Reproduction Science:
- Specialized hemophagous regions are a striking characteristic of some of these placentas yet absent in hyraxes, elephant shrews, and golden moles. It is possible that the common ancestor of the Afrotheria had an endotheliochorial placenta.
