Description: | Specimen of a fossil ammonite, Mantelliceras sp., collected from the Inflatum Zone = Dispar Zone, Upper Greensand Formation of Early Cretaceous, Late Albian age. Collected by W.D. Dinning (?).
Ammonites are extinct sea creatures that looked like octopuses, but lived in a coiled shell. The shell kept the animal floating under the water and gave it some protection. Ammonites were able to swim using jet propulsion (squirting water), and fed on fish and shrimps that they caught in their tentacles. They controlled the depth they swam at by varying the amount of gas in their shells. The shell has coils that overlap slightly and rounded ribs. It was named after the fossil collector, Gideon Mantell who found and named one of the first dinosaurs.
It is from the Cretaceous period (144 - 65 million years ago) | Publisher: | Tyne & Wear Archives & Museums | Subjects: | Cephalopoda Dinning Classification: Animalia Invertebrata W.D. (?)
