Earth's History- Geologic Time Scale Round Clock

Ugh, is it the Cenozoic yet? This fun geologist's wall clock functions as a normal clock, but features the geologic time scale instead of the hours! Starting with the formation of the Earth at 4.54 billion years ago at 12:00, this clock takes you through the four eons of Earth's history (Hadean to Archean to Proterozoic to Phanerozoic), with the latter one divided into the Paleozoic, Mesozoic, and Cenozoic eras. The actual daily time is not numbered, but the hours and minutes are marked by tickmarks on the outer edge. (The numbers are updated to be current as of 2026... e.g., the Paleozoic era now starts at 539 Ma!)
