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).

This self-standing Chrysanthemum Stone specimen is a unique and valuable find from China. Its formation, which occurred millions of years ago due to geological movement and natural processes within the rock, produces a stunning stone that resembles the chrysanthemum flower. Its milky white flower and clear grain make it a desirable addition to any collection. Despite its common composition, the rarity of its formation and lack of radioactive elements give it a high collection value, earning it a listing as a gem.

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
