Archaeological Stamp: Pottery Fragment with Handle
A pottery fragment with handle stamp from a set of five archaeological stamps issued by Jamaica caught my eye and I was fascinated. It looks exactly like the double-eye (double-ring) handle found on Jomon pottery.
3D Model of Observation Records for Early Yayoi Period Double-Mouthed Pottery (Kamitakata-Shakuzihara Site, Tomioka City)
I created a 3D model of the observation records for the Early Yayoi period double-mouted pottery, which is on display at the Chiba City Archaeological Research Center's special exhibition "The Mysterious Late Jomon Period." While I've seen double-mouted pottery from the Middle and Late Jomon periods, this was my first time observing one from the Yayoi period.
I conducted a preliminary 3D spatial analysis of the shell layers on the northern slope of the Ariyoshikita Shell Mound, examining the relationship between the prominent pottery concentration zones and cross-sections. By skewering the cross-sections, it appears possible to correlate specific strata.
I searched through my archaeological stamp collection for archaeological stamps depicting pottery with human face and found three.
All of the pottery dates to the pre-Columbian period in South America. The countries where the pottery was excavated and the stamps were issued are all different.
3D Observation Record Model of Early Yayoi Period Pottery with a Human Face (Osakidai Site, Sakura City)
I created a 3D observation record model of the Early Yayoi period pottery with a human face, which is currently on display at the Chiba City Archaeological Research Center's special exhibition "The Mysterious Late Jomon Period."
The face is gentle, but the closed eyes, sagging nose, and wrinkles suggest it is the face of a deceased person.
Comparison of Shell Layer Classifications between Sections 5 and 6
For the shell layer on the northern slope of the Ariyoshikita Shell Mound, the proposed shell layer classification from Section 6 was projected onto Section 5. The natural cliff is divided into two stages, revealing the characteristics of gully erosion. The shell layer blocks in the collapsed layer are remnants of a shell layer that was already present at the time of gully erosion.
Archaeological Stamps: Stone Plate and Grinding Stone
A large stone plate and grinding stone from the Jomon period are on display at the Chiba City Museum of Local History, but I also enjoyed finding three similar artifact stamps in my own archaeological stamp collection. All three stamps are from African countries.
Comparison of Shell Layer Classifications between Sections 6 and 7
For the shell layer on the northern slope of the Ariyoshikita Shell Mound, the proposed shell layer classification for Section 7 was projected onto Section 6. The shell layer on the slope has been largely replaced by older shell layers compared to the downstream section.
3D Models of Observation Records of Five Deer Antler Ceremonial Guards (Arami Shell Mound, Narita City)
I created 3D models of the observation records of five deer antler ceremonial guards on display at the Chiba City Archaeological Research Center's special exhibition, "The Mysterious Late Jomon Period."
The carved patterns are creative designs that are inspiring even to modern audiences.
Comparison of Shell Layer Classifications between Sections 8 and 7
For the shell layer on the northern slope of the Ariyoshikita Shell Mound, the proposed shell layer classification from Section 8 was projected onto Section 7. Erosion has created a topography consisting of flat and steep slopes in the collapsed layers, and mixed shell sand layers have been deposited as slope-like stratification, filling in the topography.
