This beautiful ammonite is Neocomites (Teschenites) flucticulus (Thieuloy, 1977) sharing a large boulder with a delicate, straight-shelled, heteromorph ammonite Bochianites. These beauties were found on a fossil field trip to Hauterivian, Early Cretaceous deposits in the Baetic Cordillera in the Spring of 2019. The Baetic Cordillera is one of the main systems of mountain ranges in Spain along the southern and eastern Iberian Peninsula. There are several productive outcrops here that yield lovely Cretaceous ammonites and other marine species.
Neocomites are known from about a dozen offshore marine deep subtidal Cretaceous deposits in France, Hungary, Italy, Romania, Slovakia and Ukraine. We also find Neocomites in the Cretaceous of British Columbia, Canada.
This lovely specimen is the first Neocomites I've seen come out of fossil deposits in Spain. It was found and prepped by the talented Manuel Peña Nieto of Córdoba, Spain.
