Descendants of the ancestors of dinosaurs

 I have always though reptiles and birds both came from Dinosaurs but apparently that is WRONG.  Only birds come from come dinosaurs.  But they did have a common ancestor before dinosaurs!  This explained on this site (note the ABC in the URL is not related to the Australian Broadcasting Corporation) and summarised in this image:

Enough with the taxonomy already.  After recently hearing of a Red-bellied Black Snake swimming in the ocean today I watched one swimming in one of the ponds at the Mallacoota Wastewater Treatment Plant (aka the poo pits).

After a few minutes it swam away from the bank and diappeared in murky water about 1 m deep.

In the afternoon the wind got up as some storms came towards the area.  A flight of pelicans were doing a little aerial surfing.
