Large, 9.9" Stephanoceras Ammonite - Dorset, England

 
This is a 9.9" Stephanoceras humphresianum ammonite fossil from Dorset, England. It is Middle Jurassic in age, or approximately 160 million years old. Comes with a display stand.



Ammonites were predatory mollusks that resembled a squid with a shell. These cephalopods had eyes, tentacles, and spiral shells. They are more closely related to a living octopus, though the shells resemble that of a nautilus. Ammonites appeared in the fossil record about 240 million years ago and they barely survived several major extinction events. The last lineages disappeared 65 million years ago at the end of the Cretaceous.
