Analyzing Tooth Serrations and Cusps
1. Establish Serrations
Look at the perimeters of the tooth. If current, serrations (small, sharp “tooth”) will likely be seen alongside the perimeters of the crown.
Serration Sorts:
| Serration Sort | Description |
|---|---|
| Finely serrated | Tiny, dense serrations |
| Coarsely serrated | Massive, spaced-out serrations |
| Intermediate serrated | Serrations of various sizes |
| Unserrated | No serrations current |
2. Rely Cusps
Cusps are pointed projections on the tooth’s crown. Word the variety of cusps on every tooth aspect. Completely different shark species have attribute cusp patterns:
Widespread Cusp Patterns:
- One cusp
- Two cusps
- Three cusps
- 5 cusps
- No cusps (tooth is flat)
3. Cusp Form and Dimension
Observe the form and measurement of the cusps. Some cusps are triangular, whereas others could also be elongated or hook-shaped. The dimensions of the cusps can range from small and sharp to giant and blunt.
