Description
This listing showcases an excellent specimen of Mortoniceras equidistans, a well-preserved ammonite fossil from the Duck Creek Formation of the Upper Albian Stage, mid-Cretaceous period. Discovered in Spring Creek, Cooke County, Texas, USA, this ammonite fossil is a prime example of the rich marine life that once flourished in the Western Interior Seaway.
Mortoniceras equidistans is characterised by its finely spaced, regularly arranged ribs and prominent tubercles located on the flanks and ventrolateral shoulders of the shell. These morphological features make it a highly desirable species for collectors and palaeontologists alike.
