"The tsunami sands just jump right out at you because they're separated by guano layers. There's no confusing the stratigraphy (layering)," explains Dr Jessica Pilarczyk.
"It makes for interesting field work; I'm not going to lie to you. The bats get very excited when people are disrupting their space. But from a geologist's point of view, this cave has the most amazing stratigraphy," she told BBC News.

Studying tree rings is called dendrochronology.
Is this guanochronology or dungochronology?

Do they call the guy that spots the tsunami layer “no s#!t sherlock”?
To: who_would_fardels_bear
And then there was the French geologist who couldn’t see the layers the other guys were talking about. Dr. No Clouseau.
