88421 - Superb Pyritized 0.39'' Phylloceras Lower Cretaceous Ammonites Morocco the teeth that are extracted

the teeth that are extracted from the depth of the mines are usually much better preserved

sedimentology

they were extracted from the same stratigraphic level

Beautiful association of two Cretolamna teeth and one Stephanodus dentary

Coloborhynchus clavirostris and Uktenadactylus probably formed together a clade within Anhangueridae

88421 - Superb Pyritized 0.39'' Phylloceras Lower Cretaceous Ammonites Morocco the teeth that are extractedIt is naturally pyritized. It has undergone a taphonomic process of permineralization in Iron Sulfide (Pyrite). Permineralization is a process of fossilization in which mineral deposits form internal casts of organisms.
