Two orthoceras fossils were found in a sea-bed matrix. Orthoceras ("straight horn") had a slender, elongated shell, with the middle of the body chamber transversely constricted, and a subcentral orthochoanitic siphuncle. The surface is ornamented by a network of fine lirae. 250 to 750 million years ago, the orthoceras mollusk lived in abundance during the Paleozoic Era. Orthoceras is a member of the class Cephalopoda and is closely related to the extinct giant Cephalopod and present-day chambered nautilus.

Ptychopariida is a large, heterogeneous order of trilobite containing some of the most primitive species known. The earliest species occurred in the second half of the Lower Cambrian period. Trilobites have facial sutures that run along the margin of the glabella and/or fixigena to the shoulder point where the cephalon meets the thorax. These sutures outline the cranidium or the main, central part of the head that does not include the librigena (free cheeks).

Museum quality, 8" tall stone containing many small ammonite fossils. The ammonites are of the species Promicroceras marstonense and are Lower Jurassic (~200 million years old) in age. The piece has been painstakingly prepared with mechanical tools to expose all of the individual ammonite fossils on one side. 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. True ammonites appeared in the fossil record about 240 million years ago. The last lineages disappeared 65 million years ago at the end of the CretaceousWeight: 11 lbs, Dimension: 16 x 2 x 8 inches

This luxurious sculpture is a bold pairing of two natural elements that make for a wildly chic accent piece. The natural horn has a matte finish and is distinctive when paired with its brass base, transforming it into a sculptural art piece.
