As far as I know, there is no debate. Icthyosaurs are not Dinosaurs, just as
Pterosaurs aren't Dinosaurs either. :) However, all three types are
Archosaurs. :)

First, the sauropod (in this case, Diplodocus) dug a hole with its rear feet.
Then, it used an "egg tube" (1) to lay the eggs in the hole. After all the
eggs were laid, they would be buried, and left to fend for themselves. I
didn't like the "egg tube" idea, nor did I like the idea the sauropods didn't
care for their young.

1 - A cylinder of muscle that extended to the ground, and the eggs were pushed
down it. This was used because the sauropod couldn't sit down and get close to
the ground, and just dropping the eggs would cause them to break.
