The study investigated how placentation changes during the different stages of pregnancy.

As placentation evolves, the relationship between embryonic and maternal tissues appears to become increasingly complex.

Does the remnant of the eggshell, found in many species with simple placentation, suppress immunological reactions during pregnancy?
Academic text (1993) -
The findings demonstrate that malaria parasitaemia prior to 20 weeks' gestation affects placentation and may contribute to poor pregnancy outcomes due to dysregulation of trophoblast invasion.

In brief, a decrease in the recruitment of new uterine glands at the onset of the annual reproductive cycle produces a situation whereby the eggshell is thinned significantly and placentation can evolve rapidly.
Academic text (1993) -
The effects of early pregnancy malaria parasitaemia could be seen on both uterine and umbilical artery blood flow, indicating alterations in placentation and villous angiogenesis, respectively.

Etymology
Placentation comes from the Latin word placenta, which meant a 'flat cake' because the organ looks like a flat, round thing that helps feed the baby. So placentation is the process of forming the placenta during pregnancy.
