Time conversions use a Julian year of exactly 365.25 days.
Since the non-avian dinosaurs
A rounded 66 million-year geological interval.
Defined examples — our methodology
The marked time is calibrated. Unmeasured illustration details are representative.

Why these numbers?
The visual compares time with time. The records below preserve each value’s basis and caveats.

66 MyrTime · reference interval
A rounded 66 million-year geological interval.
- Comparing
- Time ↔ Time
- Relative size
- Since the non-avian dinosaurs is larger on this measurement by a factor of about 66.
How to read the visual
The labelled spans and stored measurements determine the scale; unmeasured illustration details do not.
- Since the non-avian dinosaurs is labelled reference interval; treat the displayed value as a comparison anchor rather than false precision.
