Superbly Small Skulls

From International Owl Center

We finished cleaning up skulls from two new species for our skull display: Elf Owl and Burrowing Owl. That is a dime for size, not a quarter. They are tiny!

For you international folk, a US dime is just shy of 18mm in diameter. For some additional context:

Same size: UK 5 pence, CA 10 cent

Smidge off: EU 2 cent (18.75mm), AUS 1 cent (17.5mm), MEX 50 centavo (17mm)
