What species of ammonite are these? I found all of these in whitby apart from the one in the top right, wich I found in skegness. I know the one in the bottom right has a brachiopod on aswell- I would appreciate it is you could identify that too. Am I right in saying they are all dactylioceras commune, or is the one in the top right a different species of Dactyleoceras (I have forgot the full name).
Your right in saying they are Dactylioceras but they are too water worn to make a better id.
You can fill your pockets with these around Whitby, the hard thing is finding the complete ones!
