Description
Table 5. Measurements (in μm) of the eggs of Richtersius nicolai sp. nov. Eggs mounted in Hoyer’s medium; process base/height ratio is expressed as percentage. Range refers to the smallest and the largest structure among all measured specimens. Abbreviations: N = number of eggs/structures measured; SD = standard deviation.

| Egg full diameter | 13 | 135.5 –157.8 | 148.4 | 7.3 |
| Process height | 48 | 10.1 –19.1 | 14.1 | 2.1 |
| Process base width | 48 | 3.1–7.3 | 5.3 | 1.1 |
| Process base/height ratio | 48 | 25% –54% | 38% | 7% |
| Inter-process distance | 48 | 4.6–10.1 | 6.9 | 1.3 |
