Marsh Marigold or Kingcup ?

Observation - Marsh Marigold or Kingcup ? - UK and Ireland. Description: The ground near the damp area of our wild garden is covered in these yellow flowers. I thought they might be Marsh Marigolds or Kingcups, but I think there are too many petals to be either of these and the leaves do not look quite right.
