The location for the burying of the dung is significant too. When I first discovered them they were driving their ball on a relatively fresh and clean land. They carried that to, and buried too, the land congested with grasses, leaves etc. Studying from a common man’s perspective I think that is for securing their possession from any unexpected threat. They are also known for laying eggs on/into the collected poop. Sometimes, the male alone carries the dung, buries that and comes back to the opening of the tunnel to make phenomenal signal to the nearby female for mating and laying eggs therein [1]. So, the point of security behind such choice of land cannot be discarded as almost all the lives on this planet aware of the security for their own future generations. I neither know the sex(es) of these dung beetles I found in the field nor what they do with that poop ball after burying but surely can say that these poor fellows possess a good many attitudes to influence a common man like me.

(The second link I provide here is with a little change. Firstly, it came to me as http://m.phys.org/news/2016-05-evide...dinosaurs.html . Thereafter, when I click on this to make sure again I found message knowing me that there is no such page. I search again in Google with the keywords ‘dung beetle origin’ and I found this link as mentioned in point [2]. I don’t know whether it would change again or not. Also, I’m not sure about the contents remain same with the previous ones which I followed at the time of writing this.)
