Australian soil

 I'm not claiming that my shoes or feet are objects worthy of your attention. They sometimes help to perceive the size or color of the ground and objects.
This is a scull of kangaroo. I had to put the lower jaw back in place.

 We suspect these green spots are portions of poo of some kind of bird. Or they used to belong to any other animal with an extremely loose stomach. 

 Leaves of gum trees.

 Footprints of a pelican.

 Another odd, unknown object! It's very light, tightly rolled. Looks like seaweeds+hair+something else. There were a few more of these balls. Was it wind made? We were at a beach after all...
