8" Rare Cymatoceras Nautilus Fossil – Toarcian, Jurassic – Dordogne, France – Authentic Fossil with Certificate – Alice Purnell Collection
Presenting a RARE 8" Fossil Nautilus (Cymatoceras) from the Toarcian Stage of the Early Jurassic Period, approximately 182 to 174 million years ago. This exceptional specimen was discovered in Dordogne, France, a region known for its Jurassic marine deposits, and comes from the celebrated Alice Purnell Collection.
Cymatoceras is an extinct genus of nautiloid cephalopods, known for their thick, rounded, and ornamented shells. These marine animals are related to modern-day nautiluses and were free-swimming predators of the ancient oceans. Cymatoceras is distinguished from other nautiloids by its more globular shape and strong ribbing, which adds to its visual appeal as a fossil display specimen.
The Toarcian Stage, part of the Early Jurassic, was characterised by widespread shallow seas teeming with marine life. The sedimentary limestone of Dordogne provided excellent fossil preservation, allowing rare finds like this Cymatoceras to be unearthed with their detail intact.
This 8-inch fossil is a stunning example, showing excellent definition of the shell structure and form. It serves as both a beautiful display piece and an important palaeontological specimen for collectors, educators, and enthusiasts of natural history.

Entry #4: Extinction of the Dinosaurs
    65 years ago, majestic beasts roamed the earth. So did dinosaurs. These creepy scaled bird/lizards were the undisputed rulers of the little blue marble we call home. What they lacked in intelligence they made up for with ferocity and the ever-elusive “cool factor”. So when we “discovered” that they all seemed to die in a mass extinction event, we were appropriately confused. “How could so many animals die at once?” They couldn’t have. 
    Well, dinosaurs couldn’t have been all killed at once as they are simply too cool (and strong) to let anything wipe them out. Mainstream scientists can’t even agree on what wiped them out! Some say it was an asteroid, some say volcanos, yet others say they evolved to secretly run our government! While that last one may initially contain the sweet whiffs of truthiness, it can be disproven by a simple dermatological examination. This leaves us with a problem. What could explain the sudden absence of dinosaurs 65 years ago? When I asked my grandfather, he muttered something about soap and went back to sleep. The mindwipe must have got him. Shame. 
    Anyways, after sneaking a message to a few independent scientists, I was told that it WAS an asteroid. Just not in the way that the mainstream scientists would like you to think. You see, when the asteroid hit the earth, it hit right on the edge, flipping the planet around the equator like a coin. According to leaked measurements by the USS Nautilus, which was launched in Connecticut earlier that year for this very purpose, the planet flipped completely over in seven minutes. This sudden flippage launched the dinosaurs like oh-so-many caramelized vegetables being flipped in a skillet by a skilled chef, landing on the other side relatively unharmed. 
    This explains several phenomena, like where fossil fuels come from or how Mt. Everest was formed. Oil, coal, etc are extracted directly from the coffins of deceased dinosaurs on the backside of the earth. Mt. Everest, like all mountains, was formed when an asteroid impacts the earth on the other side and dents our side upwards. 
    However, this doesn’t explain why the governments of the world are trying so hard to keep this important truth from us. Well, part of the motive could be that they have set up a treaty with our scaly friends down under, letting us get our free fossil fuels in exchange for them being allowed to extract human remains from our coffins via hydraulic pump. Of course, this is just speculation. As one of the better-kept secrets, this is hard to get concrete proof on. As always, DM us with any even tangentially related information that you may have. 
Questions are appreciated, but not mandatory. If you are told that they are mandatory, it is probably a scam. Direct message us your SSN and a photocopy of your birth certificate and we can make sure all of your information is secure.

The Chambered Nautilus
 Tucked away in the display case across from the gift shop sits a large, creamy white shell that once belonged to an ancient animal known as the nautilus. Older than the dinosaurs, these creatures first appeared around 450 million years ago, in the Late Cambrian Period, and have changed very little in the time since.
A swarm of tentacles erupts from the opening of the shell, framed by two beady black eyes and blanketed by a mass of orange speckled flesh. Hidden within the over ninety tentacles is the creature’s parrot-like mouth, which it uses to crunch on crabs, krills, shrimp, and fish.
A hypnotizing pattern of alternating orange and white bands decorate the shell, which is compartmentalized into a variety of inner chambers, some filled with gas and functioning like the ballast tanks of a submarine. Nautiluses can move themselves via jet propulsion by pumping water through their chambers and expelling it out of a tube located on the underside of their bodies called the siphon.
These “living fossils”, as some call them, belong to the same group of animals as squids, octopuses, and cuttlefish: the cephalopods (From the Greek “kephale”, meaning “head”; and “podos”, meaning “foot”). The word “nautilus” comes from the Greek “naus”, meaning “ship” and “nautilos” meaning “sailor” (it was once believed that the creature’s tentacles were used like sails).
Cephalopods are known for their long, flexible limbs which they may use for locomotion or capturing prey. These appendages are either called “arms” or “tentacles” depending on their structure. Arms have suckers and hooks all along their length and are generally shorter than tentacles, whereas tentacles are longer, have suckers only at the tip, and end in a sword-like tip called the club. Cuttlefish, squids, and nautiluses are the only cephalopods to possess tentacles. The tentacles of nautiluses are unique in that they are completely absent of suckers; the limbs are instead very sticky and can thus be used to grab onto prey.
Unlike other cephalopods, nautiluses have poor eyesight. Their eyes are pin-like, have no lenses, and can very likely only be used to detect lights and shadows. Their worldview may resemble that of a pinhole camera, with a highly focused centerfield encircled by pitchblack darkness. Nautiluses make up for their poor vision with their incredibly strong sense of smell, and they can also use their tentacles and beaks to explore their environments.
While Jules Verne’s Nautilus was able to descend to great depths, the eponymous animals choose to inhabit depths of no greater than 800 meters, lest their chambers fill with water and their shells implode from the pressure. It has been observed that nautiluses dive down hundreds of feet during the day time to avoid their predators - which include sharks, squids, and large fish - and then ascend to the shallows at night to feed. Presently, these animals inhabit the steep sloped reefs of the Indo-Pacific, the waters around Southeast Asia and Australia.
Unfortunately, these incredibly unique creatures may not be around for much longer. Treasured for their beautiful, white-and-brown patterned shells (the inner layer of which is composed of mother of pearl), overfishing of nautiluses has been an ongoing problem for decades. Their shells are often turned into jewelry and ornaments or are otherwise sold whole. Their coral reef habitats are also threatened by destruction and pollution. Because nautiluses take long to mature and have low reproductive rates, experts fear that all seven species may be highly vulnerable to human activity. Surveys done in 2010 found that nautilus populations in the Philippines had declined by as much as 80 percent since the 1980s.
Last year, at the 17th meeting of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) conference of the parties, over eighty countries voted to add all seven species of nautilus to Appendix II of the Convention.
CITES is a voluntary agreement between nations the world over to regulate the trade of animals.
According to the Convention, species listed in Appendix II are not presently threatened by extinction, but care must be taken to ensure that international trade does not change that. Sellers and traders looking to ship animals that fall under Appendix II of the Convention must first be granted an export permit or certificate.
What you can do to help nautilus conservation efforts:
1.      Avoid buying jewelry and ornaments made from nautilus shells
2.      Practice good etiquette when diving and snorkeling: Nautiluses inhabit coral reefs and these delicate environments should not be disturbed. Remember: “Look but don’t touch”
3.      For aquarium enthusiasts, consider going with a different species: Nautiluses are infamous for being difficult to keep alive in captivity. They are incredibly sensitive to changes in temperature, light, and water pressure and are accustomed to diving hundreds of feet each day. They are also known for attacking and eating fellow aquarium dwellers.

Cenoceras inornatum Nautilus Fossil – Cornbrash Formation, Callovian, Jurassic – Shorncote, Gloucestershire, UK – Genuine Fossil with Certificate – Alice Purnell Collection
This listing presents a genuine and rare Cenoceras inornatum Nautilus Fossil from the Cornbrash Formation, dated to the Callovian Stage of the Middle Jurassic Period, approximately 165 million years ago. It was discovered in Shorncote, Gloucestershire, United Kingdom, and is part of the esteemed Alice Purnell Collection.
Cenoceras inornatum belongs to the extinct genus of nautiloid cephalopods, relatives of modern-day nautiluses. These marine creatures were characterised by their smooth, planispiral shells, and were highly mobile predators of ancient seas. Unlike ammonites, which have more complex suture patterns, nautiloids like Cenoceras had simpler chamber structures and suture lines, often exhibiting a more symmetrical and evenly coiled shell.
The Cornbrash Formation is a notable Middle Jurassic geological unit composed of shelly, fossil-rich limestone and marl. Found throughout southern and central England, it yields exceptionally preserved marine fossils, including ammonites, nautiloids, bivalves, and echinoids. The marine deposits reflect warm, shallow sea conditions that were ideal for fossil preservation.
This fossil specimen is a natural, unpolished whole Nautilus shell that beautifully exhibits the classic coiled symmetry of the species. It is a striking display piece for fossil collectors, educators, or natural history enthusiasts seeking a genuine and uncommon Jurassic-era cephalopod.
