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.
Receding hairline can occur as a result of taking drugs, alcohol, having gone through a trauma or surgery, being slowly poisoned, after effects of childbirth, or as a symptom of an ailment. One of the main causes of receding hairline in women is the reduction of their estrogen levels. Similarly men can experience more hair fall when their testosterone levels decrease and that is why this problem is associated with ageing.
