Very interesting, thanks for posting. 

Though the second one keeps repeating itself which is a bit annoying.

The links didn't work for me....but I think most reptiles rely on heat from the ground and/or rotting plant matter to incubate their eggs.  For that matter, the Malleefowl (bird) does the same thing.  They lay their eggs in compost piles covered with sand and then leave them to incubate.
