Identification

The fossils of different species of ammonites can be identified, in the same way as modern shellfish; by shapes of their shells and the rings and patterns on the outside of their shells. This information combined with geological data on the locations where specimens are found enables the exact identification of particular specimens.

Ammonites are ancient cousins of Octopuses, Cuttlefish and Squid.

Location of Origin: Agadir, in Morocco

Age: 115 mya. The Earliest submarines in the world! Ammonites lived in the front section of their shell. The remaining sections forming an adjustable floatation mechanism. Buoyancy within the chambers could be adjusted through alterations in the gas/fluid balance regulated via blood flow between the chambers. Like Octopus today they could also move sideways by squirting water from a tube near their mouth.

Vision: Ammonite’s vision was reasonable though much simpler than ours. Hearing: Evidence suggests Ammonites could only sense vibration.

Amazing facts!
Blue Blood

Almost certainly Ammonites blood was blue like that of modern Octopuses whose blood uses a copper based molecule to absorb oxygen.

The spiralling observable within Ammonites matches the ratio known as the Phibanarchi series. A proportion found in the spiralling of the Milky Way, and inside the double helix of our DNA (a signature written in a once living organism of both eternity and infinity).

Ammonite Extinction

Prolonged evolutionary pressure from competition with newly evolved species, and secondly, a catastrophic shortage in the availability of the plank tonic food sources on which their young are believed to have depended following the ecological impact of climate change created by a giant meteor strike 65 million years ago is believed to have led to Ammonite extinction.
