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.
Many people are aware of the most common causes of hair loss, which include genetics, hormones, menopause, medical conditions, and stress. However, there are a wide variety of factors that can cause balding and hair thinning, some of which are often overlooked. Fungal infections of the scalp can cause balding. Treating hair loss from these fungal infections requires a different approach than with other types of hair loss. Ringworm of the scalp is a fungal infection that affects the scalp and hair fibers, causing hair loss and other irritating issues. With ringworm, small patches of itchy and scaly skin appear on the scalp, leading to excessive dandruff, flaking of the skin, and inflammation.
