help identifying this ammonite

[joaoarguello3]

Hello everyone, I need your help to identify an ammonite. Today I bought one but I bought it in a place where they only sell minerals so when I asked where it was from or more information about the fossil they told me they didn't know. I am not a great expert but I understand that most ammonite fossils are from Madagascar, although I am not saying that this one is from there. My questions are the following: Is there any way to know the age and species of the ammonite?
Before making the publication I was looking for a little information and I saw that it is very similar to Phylloceras due to the markings on the shell, which I have seen on sales sites such as ammonite from madagascar, that is why I suspect it, but I am an amateur so I don't know. any.
Thank you all

I think that you have guessed correctly that this is a Phylloceras from Madagascar.
