It lived around 75 million years ago, during the Cretaceous period, and was around 8 metres long. Both birds and crocodiles have âcloacasâ , so itâs likely that dinosaurs did too. Cloacas are one opening that deals with intestinal, reproductive, and urinary tracts.In most early bird species, males had a penis that only emerged from the cloaca to deliver sperm when they had sex. So dinos probably did too.oth birds and crocodiles have âcloacasâ , so itâs likely that dinosaurs did too. Cloacas are one opening that deals with intestinal, reproductive, and urinary tracts.

The cause of failure to grow new hair in female pattern baldness is not well understood, but it is associated with genetic predisposition, aging, and levels of hormones (particularly androgens, the male sex hormones). Changes in the levels of androgens can affect hair production.
