Help with these invert fossils!

[Guguita2104]

I found these fossils in Polvoeira beach, Portugal. I spent many time trying to identify them and research about the geological formations where they were found....However, I need that someone help me verify if those Id's are correct.

So:

1-Found in Sinemurian layers, in Praia da Polvoeira (Polvoeira beach)- My guess it's :very weathered Pachymya sp.

The same as the others:Mactromya cardioides

Another fossil:

Lower Jurassic ( Toarcian???) ammonite-maybe Lytoceras sp.

I think you are correct with the IDs for 1-5, I checked the species names, geological time and distribution for all, also I compared them with other specimens. For the ammonit I'm not sure, looks to be something else for me. Although the sutures might match, I don't see in the ornamentation the large ridges between every 5-10 small ones, characteristic for Lytoceras, but I'm not an Amo expert.
