Description
This listing features a stunning 6.5-inch specimen of the ammonite Mortoniceras (Craginites) from the Duck Creek Formation, Upper Albian Stage of the Cretaceous, discovered in Spring Creek, Cooke County, Texas, USA.
Mortoniceras (Craginites) is a genus of heteromorph ammonites that thrived in warm epicontinental seas during the Albian. This genus is notable for its moderately evolute coiling, strong ribbing, and prominent tuberculation along the flanks. These morphological features make it an attractive display piece and a valuable specimen for scientific and collector interests.
