2.1" Jurassic Ammonite (Hemilytoceras) Fossil - Madagascar

This is a 2.1" wide, Late Jurassic-aged ammonite (Hemilytoceras) fossil collected near the town of Sakaraha in the Tulear Province of Madagascar.

Ammonites were predatory cephalopod mollusks that resembled squids with spiral shells. They are more closely related to living octopuses, though their shells resemble that of nautilus species. True ammonites appeared in the fossil record about 240 million years ago during the Triassic Period. The last lineages disappeared 65 million years ago at the end of the Cretaceous.
