anterior fontanel is found between the frontal bone and two parietal bones

Anterior fontanel
The posterior fontanel would be in the back of the head. The coronal fontanel would be located in another part of the brain.
Firstly, most people are unaware that babies actually have a baby soft spot on the top of the head which is diamond or kite shaped (anterior fontanel) and another one at the back of the head which is triangular (posterior fontanel).A newborn's soft spot exists where the skull has not completely closed at birth. The anterior fontanel is generally about two inches wide and can remain to some degree until the baby is around eighteen months of age. The posterior fontanel is only half an inch wide and closes relatively quickly between the ages of six to twelve weeks.Essentially, the soft spots are an area of an infant's head where the skull plates have not yet formed together to protect the brain.the soft spot in the babies head where the skull is not fully developed.

There are 3 fontanelles. The Anterior Fontanel, Mastoid Fontanel, and the Sphenoidal Fontanel

Dehydration
two "spots" generally combine to make up the larger spot. they are the posterior fontanel and the anterior fontanel
They gradually fuse, so that eventually there is no anterior fontanel (or posterior fontanel) either.
The anterior fontanel
6-24 months
Anterior fontanel
The anterior fontanelle was soft at birth as this allows the baby's head to exit the birth canal safely. As the baby gets older, the fontanelle closes and hardens to a normal skull.
"Fontanelle" (sometimes spelled "fontanel".) There are actually four of them, but the anterior fontanelle (directly on top) is usually the most noticeable.
The posterior fontanel would be in the back of the head. The coronal fontanel would be located in another part of the brain.
