the calvarium of the adult scull is fused, in the fetus the bones making up the skull are not fused (not joined together), also the're actually quiet a lot of space around the bones - called fontanelles or "soft spots" on a baby's head that you can feel on the back of the head in many babies until 6-9 months or so and on the front of many babies until 15-18 months or so.
In the adult skeleton the coxal bones have fused (ischium, pubic, and ilium), while in the fetal skeleton these bones have not fused.
no!
The first is the fetal skull, which is much more malleable than an adult human skull, secondly it is much, much smaller than an adults'.

fetal skull moulding is the change in the shape of the fetal head during its passage in the birth canal.
1-adult skull is fused while children's and fetus 's skull is unfused.2-The fetus and children's skull is flexable the "fontanels are soft to help mom inbirth while adult skull is rigid and hard not flexable but it is breakable.3-The fetus and children's skull is smaller thinner and composed of deformable bones while adult's skull is bigger thicker and not deformable usually after age 18-25.
The fontanels allow the fetal skull to be compressed slightly during birth and also allow for brain growth during late fetal life.

well the skull grows until all the plates finally mean. the area where they meet is connected by a tissue called sutures which is a non movable ligament to hold bones together
