Dear All,
I am facing with a trouble concerning some ammonites found in the North of Spain, Cantabria region, close to Reinosa's village.
The ammonites found, looks like belongings to the Jurassic period (Middle-Sup).
I am not able to ID them because they looks belongings to differents periods (maybe Oxfordian or Callovian).
Here you have a few pictures to try to identify them.
I should be addressed to Perisphinctes (Dichotomoceras) and Alcidia...
Thanks in advance for your help,
Roberto
