Ammonite Fossil Cast - Museum-Quality Paleontological Reproduction 4H

Ammonites are among the most beautiful and widely collected fossils in the natural history world. These ancient cephalopod mollusks - relatives of the modern squid, octopus, and nautilus - lived in the Earth's oceans for approximately 330 million years before going extinct at the same mass extinction event that ended the dinosaurs, 66 million years ago. The tightly coiled, chambered shell that protected the living animal became, in death, one of the most perfectly preserved and visually striking fossils in the geological record. This Ammonite fossil cast reproduces a beautifully formed 4 in specimen in museum-quality compound stone.

330 Million Years of Ocean Elegance

This ancient cephalopod fossil replica is hand-cast in compound stone in the USA and finished with an aged patina that replicates the warm, mineral-rich tones of a matrix-embedded specimen. The intricate suture lines - the complex folded seams between shell chambers that are one of the most diagnostic features of ammonite taxonomy - are faithfully rendered on the outer surface, along with the characteristic ribbing and gentle umbilicus of the coiled shell. At 4 in H this is a compact but richly detailed piece.
