This is what happened when the scientists entered the cave where the Thylacoleo was found:

1. The cave was entered by abseiling down an 18m deep sink-hole.
2. The first task was for Dr Long to take uncontaminated samples for DNA testing, using a special suit, gloves and face mask.
3. Then the bones were individually cleaned and hardened using a plastic based glue, and photographed in situ before being carefully wrapped, packed and numbered.
4. The cave was also sampled to obtain background levels for gamma ray spectroscopy to enable accurate dating using the most modern techniques.
5. A full forensic investigation of the specimen was also undertaken, looking for traces of soft tissues, hair, blowfly pupal cases and any clues as to the cause of death of the animal.
6. In addition, sediment samples were taken to look for small animal bones (lizards, small mammals etc) to help build up a picture of the ancient ecosystem.

The cavers produced a detailed map of the cave, while the whole recovery process was recorded on film
