The species Eulamprus tympanum and Eulamprus quoyii are viviparous skinks that are said to have a Type I placenta. This research compared histological characteristics of the oviduct during pregnancy in E. tympanum and E. quoyii and assessed whether structural features are consistent with a Type I placentation. A similarity was seen in both of these species and was not consistent with a Type I placenta. Extreme folding of the uterine tissue was observed in the early stages. An increase in glands around the later stages was observed while there was no change in blood vessel density over the course of pregnancy. Our research suggests that these species may not have a simple, Type I placenta.
