Each specimen ammonite has full unbroken ornamentation of the stumpy tubercles, the whole form is good to each, some with excellent ammonitic suture patterning. All collector grade specimens. Enlarge the illustrations above to view the attributes for each ammonoid. When ordering use the reference number in each image to identify your fossil purchase.

The shell ornamentation is dominated with short stumps, these are umbilical tubercles and were part of the shells defences. Ribs are prominent in juveniles stages but tend to be less prominent in the mature cephalopod shell, when fully developed, one may reflect the need of defence became less important, becoming a fast moving nektonic carnivore in adulthood, with fewer predators when mature in size.
However there is debate on whether what appear to be spine placements were for defence or sexual morphism, distinguishing the males and females. The debates will continue as new discoveries may become apparent, particularly from this extensive fossil source in central, south eastern Morocco.
The suture patterning is a simple ammonitic type. These ammonites are from the Early Turonian Stage (Upper Cretaceous) found North of Goulmima, Morocco. Primary reference: W. J. Kennedy, A. S.
