Academic OB/GYN Cases: The House of Twins
This is a nice photo of a diamniotic/dichorionic placenta, part of a pregnancy involving two separate embryos in the same uterus.
Note the thick intervening membrane and lack of blood vessels traveling between the two placental discs, both characteristic of a di/di placenta.

Fascinating! Thank you for posting. Just out of curiosity, are twin placentas always joined, even di/di placentas?
Technically di/di placentas are separate, but they are always adherent to each other.
Beautiful. I hope I can get to see such things in person too.
That is a beautiful pair of placentas!
