Ammonites Perisphinctes in Collection Box 4x4 cm

Striking natural perisphincte ammonites in 4x4 cm box format.

This species is characterized by having thin, prominent and profuse dorsal ribs, while the thin ventral ribs branch off towards the belly.

Its collective name refers to its resemblance to the spiral horns of a ram, with which the Egyptian god Amun was depicted in his Roman adaptation (Jupiter-Amun).

The Ammonites were a group of cephalopods with a spiral shell, which thrived in the Mesozoic oceans, and abruptly went extinct along with the dinosaurs.

The group, numbering some 10,000 species, disappeared 65 million years ago, providing uncompromising support for biological evolution and evidence for our planet's changing biodiversity.

Deposits: Antarctica, Argentina, Cuba, Ethiopia, France, India, Iran, Italy, Madagascar, Poland, Portugal, United Kingdom, Russia, Saudi Arabia, Spain and Yemen.

The fossil includes a label with the name and origin and is attached to a 4 cm square cardboard box.

*The price is per unit (a single cardboard box of the four shown in the photo)

Since the samples are natural, you will receive a piece similar to the one in the photograph. The fossils come in cardboard boxes and are glued to a porex base with hot silicone; these can be removed using ethyl alcohol without damaging the fossil. The size is approximate.
