3D model of observation record of Obora B-C type pottery (Kasori shell mound, Chiba city)
I created a 3D model of the observation record of Obora B-C type pottery from the late Jomon period excavated from the Kasori shell mound in Chiba city. Obora type pottery is a different type of pottery from the Kasori shell mound.
Comparison of the Yardang topography in the Lut Desert of Iran and the Hanami River topography
The Yardang topography (wind erosion topography) in the Lut Desert of Iran is the largest in the world. To get a sense of its scale, I compared it with the Hanami River topography using a 3D model under the same conditions. It's amazing that such a topography can be created by wind alone.
Close-by excavation of a boar jawbone and three hunting tools
In 3D space, we found a place where a boar jawbone and three hunting tools were found close together. The place is surrounded by a dense area of bones and teeth. There is a possibility that a meaningful event will be discovered using the boar jawbone as a key. However, this one example may be a coincidence, so we will wait for the discovery of similar examples in the future.
Characteristics of 3D distribution of bones and teeth
Looking at the 3D distribution of bones and teeth in the shell layer study space on the northern slope, the dense area is on the middle slope. In the 3D distribution of pottery, the dense area is on the lower slope. In other words, the 3D distribution characteristics of bones and teeth are different from those of pottery. This is the first example of identifying differences in distribution characteristics of different artifacts.
I have started studying the April 2025 issue of the magazine "Geography". This time, the editorial is "Glorious History and...". It summarizes the activities of the Silk Road Travelers Group, the relationship between travel in Iran and the magazine's special issue, and provides a comprehensive understanding of Iranian history. It also touches on the history of exchanges between ancient Japan and Iran.
Observation record 3D model of Obora B-C type pottery (Kasori shell mound, Chiba city)
I created a 3D model of the observation record of Obora B-C type pottery, which is a different type of pottery from the Kasori shell mound. The pottery is in a brittle state due to secondary heating. Since the pattern is difficult to see at a glance, I made some adjustments to the observation, such as adding color gradations to a textureless 3D model.
Looking at the 3D distribution of pottery, we were able to observe a notable feature that the dense area exists at or near the lower tip of the white shell layer. This can be observed in the actual cross section of the peeled pottery. Why this is the case is an interesting topic for future investigation.
3D distribution analysis of artifacts by slope shell layer subdivision
When counting the number of artifacts by slope shell layer subdivision, the number of artifacts is greater in the white shell layer than in the brown shell layer. It is worth further consideration as to how this phenomenon should be interpreted in relation to the rise and fall of settlement activity and environmental changes (changes in sedimentary environment).
Start studying the wonderful latest Iran experience (feature in the April 2025 issue of the magazine "Geography")
Iran is an interesting country, but I have not been there yet. The author sent me a magazine in which a group of geography experts traveled to Iran and summarized their experiences in numerous articles. Although I am two months late, I will start studying Iran and enjoy it.
Five stone swords (Kasori shell mound, Chiba city) Observation record 3D model
I created a 3D model of the observation record of five stone swords excavated from the late Jomon period remains at the Kasori shell mound in Chiba city. The three stone swords excavated from the remains of dwelling No. 85 were excavated in a heated state from the burnt soil layer directly above the floor.
3D distribution analysis of artifacts by major shell layer division
A 3D distribution analysis of artifacts by major shell layer division was performed. Approximately 80% of the artifacts were excavated from slope shell layers, and approximately 10% from channel shell layers. Extraction of artifacts by major shell layer division was performed using BlenderPython, and aggregation analysis was performed in relation to the database.
