Always interesting to hear about how prehistoric creatures lived and functioned in their environments. Even if the information may seem a little weird it helps shed insight on these amazing creatures and helps us to understand living creatures we will never get the privilege to see in person. Like I would have never expected increased melanin of the "orifice" though in retrospect it makes some sense for courtship. Another thing, although cloaca's may seem very strange compared to the usual mammalian set of equipment, they are kind of the "default" state of most vertebrates only separating into multiple discreet sections during the embryonic development of some groups (I.e the majority of mammals)

it's funny that reptiles and birds combined reproduction and shitting into one organ

Yeah.. birds are effective like that. Pooping and peeing at the same time. :|
