Table 2 Starch morphotypes. Detailed description of the starch morphotypes recovered from the dental calculus of the ancient community
Morphotype | Morphologic and morphometric description | Taxonomic group |
|---|---|---|
I | Irregular ovoid to reniform granules; size range. 20–52 μm in length and 17–38 μm in width; clear concentric lamellae; hilum is obscured; presence of a longitudinal cleft | Fabaceae |
II | Pyriform to reniform granules; size range, 19–35 μm in length and 16–27 μm in width; faintly visible lamellae; invisible hilum | Fagaceae |
III | Multifaceted polyhedral units on one side and dome shaped on the other one; individual granule size, 5–14 μm in length and 5–12 in width; indistinct hilum and lamellae | Poeae |
IV | Polyhedral granules with pentagonal or hexagonal faces and rounded off edges; size range, 3–16 μm in length and 2–15 in width; centric distinct hilum; radial fissures; indistinct lamellae | Paniceae |
V | Discoidal granules; size range, 6–36 μm in length and 4–30 μm in width; indistinct hilum; concentric, complete and distinct lamellae; sometimes, longitudinal fissures were present. | Triticeae |
VI | Ovoidal granules with flattened surfaces; size range, 8–20 μm in length and 7–17 μm in width; indistinct lamellae; deep radial fissures starting from a centric hilum | Sorghum sp. |
