Desmoceras ammonite fossil specimens dated to the lower Cretaceous period, making them over 102 million years old, these samples were found in the Mahajanga Province, Madagascar and exhibit a silver coloured shell, very faint ribbing and a shallow coil. They are approximately 25 mm in diameter and also show iridescence on the shells surface. Suitable for older children, collectors, gifts and educational use, the sample will come supplied in a polythene bag with a label.
Desmoceras is an extinct species of ammonite which lived during the lower end of the Cretaceous period, dating these fossil specimens to between 110 to 102 million years old. They are found alongside other ammonites which lived during this time period including douvilleiceras and cleoniceras. The smooth shell and lack of distinct ribbing has lead to geologists to infer that this particular species of ammanoid was fast swimming anektonic carnivore, actively hunting its prey. These samples were collected from the Mahajanga Province, Madagascar, a famous locality for excellent quality ammonite specimens, they are approximately 25 to 30 mm in diameter with a silver coloured shell which, when viewed under certain angles of light, also has an iridescent lustre to it. Supplied in small polythene bag with a label, suitable for older children and educational use.
