1.2" Cretaceous Hoploscaphites Ammonite Fossil - Montana
This is a 1.2" Hoploscaphities nodosus ammonite fossil collected from the Pierre Shale of Montana. The ammonite is in great condition considering the difficulty of removing it from the rock it's found in.
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.
