HUGE ABERRANT AMMONITE
HUGE ABERRANT AMMONITE. Most ammonites have the familiar tight spiral shape that is so familiar, but some ammonites known as aberrant ammonites began to straighten out forming a variety of odd interesting shapes. Why this happened after more than 200 million years of having only the spiral shape is unknown, but some species did change 70-120 million years ago. This huge 13 x 7 inch dark brown ammonite, Ancyloceras, is a perfect example of an aberrant ammonite looking something like a saxophone. It is 110 million years old and was found in the Atlas mountains of Southern Morocco. It is particularly large at 13 inches (most specimens are between 4-7 inches long) and very well preserved with its curved dark brown living chamber (the tentacled animal lived in only the last chamber) showing excellent detail. Only the initial small chambers at the other end are either missing or still contained in the matrix still remaining for stability. This large and spectacular ammonite would be the perfect specimen of the aberrant type.
