a good read.... seems they went into the puka in the ground...

"At Makauwahi, the conditions are remarkable. The alkaline limestone and the acidic groundwater cancel each other out and create the perfect neutral pH. “This is the Goldilocks zone—just right,” he says. “Everything in here is preserved. It’s like pages in a diary. And this process has been operating for thousands of years.” An acidic environment would have destroyed bones, while an alkaline environment would have destroyed plant fossils. But here, not just animal fossils, but also shells, seeds, leaves, and wood, as well as billions of microscopic algae, pollen, and spores are embedded in the layers that extend as far as 33 feet deep to the sinkhole’s floor."
