 analyzed the cave and its contents in 1822. He determined that the bones were from the remains of animals brought into the cave by hyenas who had been using it for a den, and not a result of the biblical flood floating animal remains in from distant lands as had first been thought. His reconstruction of an ancient eco-system from detailed analysis of fossil evidence was admired at the time, and considered to be an example of how geohistorical research should be done.

Discovery and analysis

The entrance to the cave was found by limestone quarry workers in the summer of 1821. The quarry workers assumed that the abundant bones buried in the cave floor were the remains of cattle that had been dumped in the cave after dying from some past epidemic. They used some of the bones to fill potholes in a nearby road, where an amateur naturalist noticed them and realized that they were not the remains of livestock. This attracted the attention of numerous fossil collectors. Some of the fossils were sent to William Clift

 was told about the cave and shown some of the fossils by a colleague at Oxford.

Buckland began his investigation believing that the fossils in the cave were diluvial, that is that they had been deposited there by a deluge that had washed them from far away, possibly the Biblical flood. However, upon further investigation he realized that the cave had never been open to the surface through its roof, and that the only entrance that had ever been open to the outside world was too small for the carcasses of animals as large as elephants or hippos to have floated in. He began to suspect that the animals had lived in the local area, and that the hyenas had used the cave as a den and brought in remains of the various animals they fed on. This hypothesis was supported by the fact that many of the bones showed signs of having been gnawed prior to fossilization, and by the presence of objects Buckland suspected to be fossilized hyena dung.

:

The hyaenas, gentlemen, preferred the flesh of elephants, rhinoceros, deer, cows, horses, etc., but sometimes, unable to procure these, & half starved, they used to come out of the narrow entrance of their cave in the evening down to the water's edge of a lake which must once have been there, & so helped themselves to some of the innumerable water-rats in wh[ich] the lake abounded.


He developed these ideas further in his 1823 book Reliquiae Diluvianae; or, Observations on the organic remains contained in caves, fissures, and diluvial gravel, and on other geological phenomena, attesting the action of an universal deluge, challenging the belief that the bones were brought to the cave by Noah's flood and providing detailed evidence that instead hyenas had used the cave as a den into which they brought the bones of their prey.
