Here is a very nice, above average quality, specimen of South Dakota Ammonites. This exceptional specimen is from Edgemont in western South Dakota. The well-preserved Ammonite appears to be a Placenticeras and measures 2 3/8″ x 1 3/4″. It sits in a matrix measuring 3″ x 1 3/8″ x 2 5/8″. In its excavation the Ammonite was separated from its matrix but has been expertly restored. A great way to begin your fossil collection.

Ammonites are extinct members of the cephalopod group of mollusks. Only a limited number of species have survived to the present day which includes the squid and the chambered nautilus. Ammonites had a multi-chambered shell, and added more chambers as it grew, always living in the outer chamber. They lived in the Cretaceous period some 63 to 130 million years ago.
