2. Fig. 1
Ectocranial (a), endocranial (b) and radiographic (c) suture patterns of a 1 year old skull (Sample No. 1). Serrate type suture pattern is visible in certain area (block arrow) in the radiographic pattern while the corresponding area in the ectocranial (block arrow) and endocranial (block arrow) surfaces reveal sutures that lack serrations. Wavy pattern of suture is seen in an area (normal arrow) in the ectocranial surface while the corresponding area in the endocranial surface (normal arrow) and the radiographic pattern (normal arrow) reveal serrate pattern.

3. Fig. 2
Ectocranial (a), endocranial (b) and radiographic (c) suture pattern of a 1½ year old skull (Sample No. 2). The ectocranial and endocranial patterns, including along the contours of the Wormian bones appear to be more similar. Serrate type of sutures is visible in certain areas (block arrow) in the radiographic pattern. While the corresponding area in the ectocranial surface (block arrow) does not reveal serrations while in the endocranial surface (block arrow) it reveals serrations. Normal arrows indicate the zone of lack of visibility of ectocranial and endocranial suture pattern in the radiographic pattern.

4. Fig. 3
Ectocranial (a), endocranial (b) and radiographic (c) suture patterns of a 1½ year old skull (Sample No. 3). Note the absence of serrations in the ectocranial pattern (block arrow), presence of limited serrations in the endocranial pattern (block arrow) and the predominance of serrations in the radiographic pattern (block arrow), the latter attributable to the interdigitations. Normal arrows indicate region of lack of visibility of ectocranial and endocranial suture patterns in the radiographic pattern.

5. Fig. 4
Ectocranial (a), endocranial (b) and radiographic (c) suture patterns of a 2½ year old skull (Sample No. 5). Block arrows indicate predominance of endocranial suture pattern in the radiographic pattern. The normal arrows indicate a zone of hazy recording of ectocranial and endocranial suture patterns in the radiographic pattern.

6. Fig. 5
Ectocranial (a), endocranial (b) and radiographic (c) suture patterns of a 3 year old skull (Sample No.6). Note the presence of spike in the ectocranial pattern (arrow), its absence in endocranial pattern (arrow). In the radiographic pattern, the spike is not legible and in its location are seen serrations (arrow) although such serrations are not seen in the ectocranial or the endocranial patterns.

7. Fig. 6
Ectocranial (a), endocranial (b) and radiographic (c) suture patterns of a 6 year old skull (Sample No. 13). Serrate type of sutures is seen in the area in the radiographic pattern (normal arrow) while serrate type is absent in the ectocranial (normal arrow) and endocranial (normal arrow) patterns. The patterned area in the endocranial surface (block arrow) appears different from the pattern in the ectocranial surface (block arrow) and the patterns in the radiograph (block arrow).

8. Fig. 7
Ectocranial (a), endocranial (b) and radiographic (c) patterns of a 6 year old skull (Sample No. 15). The block arrows indicate zone of lack of radiographic recording of ectocranial and endocranial patterns in the radiographic pattern. The differences between the ectocranial and endocranial suture patterns appear more striking along the contours of the Wormian bone (block arrows).

9. Fig. 8
Ectocranial (a), endocranial (b) and radiographic (c) patterns of a 6 year old skull (Sample No. 16). Denticulate pattern of suture is seen in the ectocranial surface (block arrow) while the corresponding area in the endocranial surface (block arrow) appears wavy whereas in the radiographic pattern (block arrow) the corresponding zone is seen revealing typically serrate type sutures.

12. Fig. 11
Ectocranial (a) and radiographic patterns (b) of a skull aged 5 year (Sample No. 9). The interdigitations have been exposed (a) for comparing their appearance in the radiographic pattern (b). The interdigitations, which are seen with blunt and broader edges in the exposed region (a) appear serrated in the radiographic pattern (b).

13. Fig. 12
Gradation in the increasing endocranial beveling in the inter-parietal zone near the lambda in skulls as seen in cross sections of the skull table. The thickness of the endocranial surface of the abutting bones alongside the sutural area in relation to the thickness of the skull table away from the sutural zone in skulls aged 1½ years (a) (Sample No. 3), 2½ years (b) (Sample No. 5), 5 years (c) (Sample No. 11), 7 years (d) (Sample No. 18) and (e) (Sample No. 19). Arrow in (e) indicates an interdigitation making inroad into the diploe.
