Mammites ammonite fossil from Morocco

[A.Passero]

Hi everyone,

 

I recently received this mammites ammonite fossil directly from Morocco from a source I trust, however on closer inspection the jigsaw pattern and spines just looked a little off to me. The spines are uneven and the jigsaw patterns look like they could have been drilled in. After doing some research it doesn't really seem like mammites are faked often or ever but there is always that possibility that this is a bad prep or completely fake (I am also aware that ammonites from Morocco tend to be rougher than a lot of other locals and I am not super familiar with Moroccan ammonites in general). Hoping to get a second opinion. 

Thanks to anyone who weighs in!

what a nice one!

 

Most of them I have seen have darker ends of the nodes. Seems to be a kind of limonite

I do not know many faked ones, some have parts restored or are replaced on the matrix (or another nodule...), yours looks nearly 100% perfect to me. Might be there is a little color on it, but I dont think really.

This ammonites come from Asfla, Goulmima, El-Rachidia, high Atlas, lower turonian

I wonder about the two spines circled in red. The centre might be carved I added a picture of mine for comparison.

It's mostly real, if not entirely.;

I don't think the spines have been added but it does happen.

 The centre has definitely been excavated to some extent and the ribs there might be artistic, This is normal for most ammonites sold from this region.
