Large pyrite Eteoderoceras (Eoderoceras) ammonite fossil (86 mm)A stunning example of a highly pyritised ammonite fossil of the species Eteoderoceras (Eoderoceras) armatum from the world famous Jurassic Coast beach of Charmouth, Dorset UK.

A stunning example of a highly pyritised ammonite fossil of the species Eteoderoceras (Eoderoceras) armatum from the world-famous Jurassic Coast beach of Charmouth, Dorset UK.

The fossil measures 86 mm (3.4 inches) across with matrix, which is very large for this species. 

The ammonite is well preserved with strong ribbing and suture lines and is clean on both sides (which is hard to find with this species). It also has some of the much sought-after spines still preserved and it has a lovely metallic colour and shine. 

These are very popular ammonites and examples like this are uncommon these days. It weighs 225 grams.

These Eteoderoceras ammonites are often called the "king of pyrites" as they are the largest and most impressive pyrite ammonites found on the Jurassic Coast.

Around 196 million years old, this fossil would make a wonderful addition to any collection.

Best Dog Bone
Flavor Name: Beef, Size: Large
This is one of the best bones I've seen and I have always lived with dogs. The shape makes it so ergonomic for the dog, both of mine hold the bone down with both paws then chew the part standing up. One of my dogs was able to enjoy this while wearing a cone after surgery, supporting her natural behavior and keeping her busy. These are great for our 11 month old puppy because he was struggling to figure out how to brace the bone without it rubbing his paws, so was bracing on furniture and getting in trouble. Now he can hold the T part easily and doesn't need to use other objects he shouldn't chew by accident. They are durable, too. I got these about 2 months ago and they are barely worn with a rotty/pit/Shepard mix male puppy. If you know dogs, you know that means this is a solid durable bone! I will for sure keep these on hand for years as they are a preferred chew in my house!

Doggy Delight
Flavor Name: Beef, Size: Medium
Ever felt like your dog’s chew toys are on the fritz, ending up shredded like yesterday’s sandwich? The SPOT Bam-bones PLUS T Bone is here to save the day, offering a durable and tasty solution for aggressive chewers and teething puppies alike. These bamboo fiber and nylon chews are like the super-tough treats your dog dreams of, providing hours of gnawing joy without the splintering mess. My bulldog, who treats his chew toys like they’re part of a survival game, has found his perfect match in these T Bones. The beef flavor is irresistible, making them a favorite among picky pups and ensuring they stay engaged without turning into edible confetti. The 6-inch size is perfect for keeping his jaws busy without overwhelming his mouth – a win-win for both of us. The non-splintering design is a blessing, preventing any painful encounters with broken chews and keeping our home safe from unexpected trips to the vet. Plus, the durable construction means these chews last longer than my patience during a doggy tantrum – and that’s saying something! However, the T Bones can sometimes feel like they’re too tough, requiring a bit of extra chewing to fully enjoy – turning every chew session into a mini workout for your dog’s jaws. Additionally, the price point is slightly higher than standard chews, but the durability and quality make it worth every penny. Overall, the SPOT Bam-bones PLUS T Bone is a fantastic choice for dog owners looking to provide their pets with a long-lasting and enjoyable chew experience. It’s tough, tasty, and built to withstand even the most enthusiastic chewers. A solid 5-star rating for its durability and flavor, with a tiny star lost to its occasional toughness challenges.

The Ultimate Solution for Power Chewers!
Flavor Name: Beef, Size: Medium
I have a Pitbull mix who can usually destroy "tough" toys in minutes, but the Bam-Bones Plus is a total game-changer. The bamboo and nylon blend is incredibly dense; it satisfies that natural urge to chew without splintering like real wood or falling apart like rubber. It wears down slowly and safely, giving my dog weeks of use rather than minutes. ​Smart, Functional Design ​The T-bone shape is brilliant because of the "paw-grip" base—it makes it so easy for my dog to hold it steady while she works on it. I’ve also noticed her teeth looking much cleaner since we started using this, as the raised textures act like a natural toothbrush. Plus, the infused beef scent keeps her interested much longer than a plain nylon bone ever could. ​Final Verdict ​This is a must-have for any owner of a large or aggressive chewer. It’s safe, long-lasting, and provides excellent mental stimulation.
