The mandible develops through a process known as intercartilaginous ossification.
The calvaria including the parietal, frontal, temporal,and occipital bones form by intramembranous ossification. The skull base develops via endochondral ossification.
it develops in the diaphysis in long bones
Ossification
Ossification means bone growth or formation. I will be disscussing breifly normal or physiological ossification because there is pathological ossification.There are two types of ossification in the human body: endochondral and intramembranous. Most of the bones in the human skeleton , especially the long and short bones, develop via endochondrial ossification, but some including the clavicle and most of the bones of the skull( flat bones) are formed by the intramembranous type. Intramembranous ossification , the source of most of the flat bones, is so called because it takes place within condensations of mesenchymal tissue and not by replacement of pre-existing piece of hyaline cartilage as the case in endochondral ossification. The frontal and parietal bones of the skull, as well as parts of the temporal and occipital bones and the mandible and maxilla, are formed by intra membranous ossification. This process also contributes to the growth of short bones and the thickening (not the lengthening) of long bones.
Intramembranous ossification
Intramembranous bones are always flat bones. Parts of the skull, mandible and the maxilla are all considered to be intramembranous bones.
The calvaria including the parietal, frontal, temporal,and occipital bones form by intramembranous ossification. The skull base develops via endochondral ossification.

In humans the skull is made up of 22 bones and except for the Mandible, joined together by Sutures, immovable joints formed by ossification, fibres permtting flexibility.

ossification
Ossification (or osteogenesis) is the generic term for bone formation. There are two basic types: membranous ossification and endochondral ossification.
Endochondral ossification
