Table 1. The quantity of invertebrate–nematode associations from the mid-Cretaceous Kachin amber (~99 Ma), Eocene Baltic amber (~45 Ma) and Miocene Dominican amber (~18 Ma).
| Amber source | Host type | Quantity | FOI | 95% CI |
|---|---|---|---|---|
| Kachin amber | Holometabola | 10 | 58.33% | 38.80–75.56% |
| Other invertebrates | 14 | |||
| Baltic amber | Holometabola | 16 | 20.00% | 7.49–42.18% |
| Other invertebrates | 4 | |||
| Dominican amber | Holometabola | 32 | 20.00% | 10.24–35.01% |
| Other invertebrates | 8 |
95 % CI is calculated using the Agresti-Coull method of the “binom.confint” function from the binom R package (https://cran.r-project.org/package=binom) of R 4.2.2. Abbreviations: FOI, frequency of other invertebrates; CI, confidence intervals.
