Abstract in brief

  • The African lizard Trachylepis ivensi exhibits a highly specialized placental system where fetal tissues invade the uterine lining, a trait previously thought to be unique to mammals, facilitating direct contact with maternal blood vessels.
  • During development, early placentas form from chorionic and choriovitelline membranes, with fetal tissue replacing the uterine epithelium and establishing an endotheliochorial placental connection.
  • This species shows unique developmental features, including the temporary presence of a choriovitelline membrane and the extensive invasion of fetal tissues, making it one of the most advanced examples of placental adaptation among reptiles.]
