Mammites ammonite fossil from Morocco
A.Passero posted a topic in Is It Real? How to Recognize Fossil Fabrications
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! -
It has been to long since we posted a fieldtrip, but the curent worldwide situation did hamper our fossil hunts. A few days before Chritmas the situation in France changed and we could again go to the beaches in the North for fossil hunts. The 24th we went to the "Grand Blanc Nez" to prospect the turonian boulders en hopfully score a few big ammonites. This time we were als prepared for big finds: we took a handcart with us, because the previous time we had trouble to bring a couple of ammonites back to the car due to their weight ( 2 km on foot with more than 30 kg of ammonites is hell ). The weather conditions of the past few days had cleared up a lot of boulders and it didn't take long for the first ammonites to appear. Natalie found the first specimen, a Lewesiceras peramplum from over 30cm in diameter and a while later a loose Mammites nodosoides. A while later It was my turn and I found an large Mammites nodosoides from around 30cm lying between the rocks. a few extra ammonites were found, but of lesser quality. Halfway our day Natalie found a chalk boulder with a few bone fragments peeking out. not sure of what it could be we took it back home to see what the preparation would give. while heading back Natalie found the last ammonite of that day, this time a Fagesia catinus wich was a nice addition since we diddent had this genus in our collection yet. The ammonites where prepped over the following couple of days, but at first sight the bones didn't seem prommising so they were left asside for a while. So earlier this week we picked it back up and tried to prep it further. tou our surprise one of the fragments turned uot to be a complete marine reptile vert Natalie was overjoyed with this fossil. Just waiting for us on the beach : The prepped specimens: Mammites nodosoides ( 30 cm ) Lewesiceras peramplum ( 34cm ) Fagesia catinus ( 27 cm ) The marine reptile vert ( probably plesiosauria )

I found this specimen in a crate full of unprepared ammontes under the table of a Morrocan vendor at a fossil show in Filderstadt-Leinfelden. It was covered "from head to toe" with oysters, but I cold see upon inspection that they would be removeable. In the end I decided to keep them attached to one side. The calcite internal mold reveals the sutures excellently as well as the septal wall in the third photo. The fact that this is just the phragmocone shows how large this ammonite could have been.
