Brown Orthoceras Fossil Heart Pendants –
These orthocone cephalopods are conspicuous in the fossil record for their occasional but persistent appearances in monospecific assemblages dense enough to form individual beds of limestone that often are regional key beds. Limestones that consist of monospecific assemblages of orthocone cephalopods are known as either cephalopod beds. The Baltic island of Öland off the southern coast of Sweden has many quarries that yield orthocone nautiloids of great beauty. For centuries Öland has supplied greater Europe with material for floors, stairs and grave stones. This hard limestone is durable and the fossil inclusions make it very desirable. Occasionally the chambers of the fossil shells are colored differently. The ground water minerals that percolated the strata during diagenesis determines the color. Greens and browns are most common. Orthoceras grew to a length of 15 centimeters (6 inches) and fed upon small animals.
