The text for the "killer babies" gene suggests you cannot normally place new dinosaurs in occupied spaces, however the rules for placing new dinosaurs only says to place them in space adjacent to one of your dinosaurs.
So, can new dinosaurs be placed into spaces with enemies and/or your own pieces under normal conditions?
In general, my biggest confusion on first reading the rules is on when and how dinosaurs can simultaneously occupy the same space, so any clarification on this issue would be greatly appreciated.
You attack with killer babies to spaces adjecent your dinos. If the killer baby attack is successful, you will remove the enemy dinosaur and place your own newlyborn dinosaur in the space. If you fail, there is no birth and your baby dies.
Always only one dino per space.
