Pair Of Ammonite (Perisphinctes) Fossils - Jurassic

 
 
This is a pair of ammonite (Perisphinctes sp.) fossils in a natural association collected near Sakaraha in the Tulear Province of Madagascar. They are Jurassic (Oxfordian Stage) in age or approximately 160 million years old.



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.
