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.
Tight braiding, using rollers or hot curlers, and running hair picks through tight curls can also damage and break hair. However, these procedures don't cause baldness. In most instances hair grows back normally if the source of the problem is removed. Still, severe damage to the hair or scalp sometimes causes permanent bald patches. Medical conditions. Thyroid disease, lupus, diabetes, iron deficiency anemia, eating disorders, and anemia can cause hair loss. Most times, when the underlying condition is treated, the hair will return unless there is scarring as in some forms of lupus, lichen planus or follicular disorders. Diet. A low-protein diet or severely calorie-restricted diet can also cause temporary hair loss.
