Hello, I am new here so please bear with me,
I have been picking these up over the last decade of walking my dog on the coast of Thyborøn in West Jutland, Denmark.
Incidentally, this is where the sea-battle of Jutland took place during the first world war.
My questions are very basic:
1) These are all fossils right?
And if this is correct,
2) How old are they and by how much would you say their respective age differs, is this even possible to say?
3) Are any of these interesting or considered good quality?
These are laid out in a similar pattern. Sorted by color and size and apparent quality.
Ask me for better images of any one of these and I will deliver ASAP. Simply ask for the
specific shell by number starting from the upper left corner, the upper line will be 1--5 from left to right
and the second line will 6-10 from left to right etc.
Thank you very much,
Dannie
