Description
This is a rare Sciponoceras baculoides fossil ammonite, dating to the Lower Cenomanian stage of the Late Cretaceous period (~100-96 million years ago), discovered in Sarthe, France. Sciponoceras belongs to a group of straight-shelled ammonites known as Baculitidae, which adapted to open marine environments. Unlike coiled ammonites, Sciponoceras evolved an elongated, uncoiled shell, allowing it to float and move efficiently in the vast Cretaceous seas.
Fossils from the Cenomanian stage represent a critical period of ammonite evolution, making this specimen scientifically significant and highly collectible. The Sarthe region of France is known for its well-preserved Cretaceous marine deposits, providing insight into the diversity of ancient cephalopods.
