JohnJ Posted April 3, 2020 Share Posted April 3, 2020 Will, it looks like a composite of two different specimens that may, or may not be the same species. 4 The human mind has the ability to believe anything is true. - JJ Link to comment Share on other sites More sharing options...
Tidgy's Dad Posted April 3, 2020 Share Posted April 3, 2020 Yup, two pieces stuck together with a sort of molded filler. More common than complete specimens. It's Ancyloceras (Audiloceras) from the Lower Cretaceous, (Barremian) from somewhere just outside Agadir, I expect. 3 Life's Good! Tortoise Friend.

Notidanodon Posted April 3, 2020 Author Share Posted April 3, 2020 thanks @JohnJ i was slightly supicious of this but i guess i was convinced by the side in the first pic and chalked it up to just some repeair, ill dig around at some point and see what i find, maybe acetone will work loks more like cement though @Tidgy's Dad thanks so much, thats great some more info that i found, which formation do you think these came from the options are the shallow-marine (Bouzergoun Formation) or shelf deposits (Tamzergout and Oued Tidzi formations), that crop out in a corridor along the Moroccan coast between the cities of Agadir and Essaouira, this info was found in this paper A revised ammonoid biostratigraphy for the Aptian of NW Africa: Essaouira-Agadir Basin, Morocco https://www.research.manchester.ac.uk/portal/files/58246625/Luber_et_al_2017_A_revised_ammonoid_biostratigraphy_NW_Africa.pdf 1 Link to comment Share on other sites More sharing options...
Tidgy's Dad Posted April 3, 2020 Share Posted April 3, 2020 Not a clue. Also, looking at it, it may be Acrioceras if it doesn't have any spines or tubercles. If it does have them, It's probably Ancyloceras, but i can't see if yours has bumps or not, is it just weathering or prepping marks? 2 Life's Good! Tortoise Friend.

caterpillar Posted April 4, 2020 Share Posted April 4, 2020 It could be Ancylezeiceras from upper barremian but it's difficult to say because it's a composite 2 http://www.paleotheque.fr Link to comment Share on other sites More sharing options...
New Members Luc G. Bulot Posted November 29, 2020 New Members Share Posted November 29, 2020 Hi... Yes it is a composite... The spire looks like a juvenile Balearites or Pseudothurmannia of latest Hauterivian age. The hook and shaft clearly belong to Ancylezeiceras, and likely to A. breistrofferi or a closely allied form. It is a late Barremian ammonite that is sometimes considered as the microconch form of Camereiceras (see Bert, 2013 for example). Regarding the lithostratigraphic occurrence, these forms are not uncommon in the upper part of the Taboulouart Formation a few meters below the base of the Bouzergoun Fm. Preservation of your specimen suggests a condensed horizon such as the ones that occur in the Tamri area. Hope this helps 5 Link to comment Share on other sites More sharing options...
