A stunning example of a calcite ammonite fossil of the species Asteroceras obtusum from the world-famous Jurassic Coast beach of Lyme Regis, Dorset UK.

The ammonite sits inside the original piece of limestone matrix in which it was found, that has been split open to reveal both the positive and negative parts of the shell. The main piece of matrix measures 165 mm (6.5 inches) across and the fossil ammonite measures 68 mm (2.72 inches) across. The ammonite is well preserved and has been prepared out of the rock to reveal the shell. Part of the outer whorl is missing, which likely happened when the rock fell from the cliffs to the beach.

There is also an unusual bivalve shellfish in the aperture (shell opening) of the ammonite.

This is what is known as a "popped" ammonite, meaning that when the rock split, both the positive shell and cast in the matrix were revealed. The ribs are very finely defined and the mottled yellow and brown colour is beautiful. The two pieces of matrix fit back together, hiding the surprise within, and the both have cut-flat bases to allow them to be displayed free standing. 

A great example of the species and impressive in the flesh. Both piece of matrix weigh 2066 grams together. These are very sought after ammonites from this world-famous location.

Around 196 million years old (Sinemurian, Early Jurassic), this fossil would make a wonderful addition to any collection.

Hit or miss

I’ve purchased this item multiple times. Twice now, I got duds. Within minutes of opening the package, the ball was destroyed. The other times, it lasted months! I don’t know how to explain it.

Still squeaking after all these days!
Size: Jumbo, Style: Beef
My power chewer GSPs usually wreck all "tough" toys in less than an hour, especially if they squeak. These seem pricey but I can say it's held up really well. After about three weeks, it's still hanging in there! The stripes are worn off but the squeaker still squeaks and that's what it's all about.

Long lasting scent and has not been destroyed by my heavy chewer.
Size: Jumbo, Style: Bacon
My medium puppy loves this ball. She already has the smaller size but appears to enjoy the challenge of catching the large one. An added benefit is it's easier for me to win it back when we fight (play fighting) for it. The scent really lasts. I've had the smaller version for a few months and the scent is still there. Does it really smell like bacon? Not to my nose but the puppy thinks it's awesome. The ball itself is really tough. The pup can destroy a tennis ball in a day. Except for a few teeth marks these balls are holding together great.

Worth every penny—my beagle is obsessed
Size: Medium, Style: Cheddar Cheese, Size: Medium, Style: Cheddar Cheese
No dog toy is indestructible if you have a hound or a pit. I happen to have a combination of both. This toy is the best $12 you could possibly spend for a dog that likes to “kill” their toys. The only reason I’m buying more is because I keep losing them. My dog is a rescue. She’s half beagle, a quarter boxer, and a quarter pit bull. She’s a tiny fire-cracker and I lover her to pieces. And she loves tennis balls to pieces. Literally. She adores tennis balls, squeaky toys, and food. She will absolutely try to surgically extract the squeaker from any toy she gets because she has a high prey-drive. These balls last usually at least a week before she manages to dislodge the squeaker or puncture the squeaking mechanism, but I still have one I got about six months ago that has the paint worn off and it still squeaks. This ball literally has everything. It squeaks, it bounces pretty high, it looks like a real tennis ball so my girl recognizes them as “toy” immediately, and they smell good. These balls in particular last forever. I got her a can of regular tennis balls and she had them in four pieces within 10 minutes or less, which is not healthy for her because she likes to eat the pieces. For this dog toy, I have never seen her crack it. She’s pushed the squeaker inside of exactly one of them so far, and it stayed inside the ball. Much safer than a toy that she can possibly ingest. The toys come in several colors, but it’s not just to make them look cute and colorful. The colors correspond to flavors, as each of the balls has a different scent. I’ve sniffed them and noticed there’s a mild food smell beneath the rubber scent. I can tell that dogs really do get a kick out of the “flavors.” I’ve taken these to the dog park and all the dogs want the Playology tennis ball, even if we have other generic balls flying around. My dog even has favorites. We have a muscle-head pit bull/staffy mix at the park who is a giant meat-ball. He got his hands on one of these and he wasn’t even able to break it open for at least 20 minutes of deliberate chewing. My girl’s favorite “flavor” for a long time was beef (the red one). The blue “peanut butter” flavor is the easiest one to find in stores. She was obsessed with a purple one for a while, apparently it was bacon flavor. I couldn’t find that one! I saw that Amazon has an orange “cheese” flavor and knew she’d love it. She’s obsessed. I really wanted to leave this review to convince people to invest in this product. Your dog will be so happy, and this company made something great. I’m worried because I went on their website yesterday and they had only one or two colors available. I don’t want them to stop making this amazing toy. I hope they don’t lose business because their product is TOO durable!! If they make more flavors, or maybe make some multi-dog (tug ropes?) or similar, I’ll definitely continue to be a customer. Please keep making these awesome tennis balls!

Not Squeakable for Mini/Toy Aussies
Size: Medium (VALUE 2-Pack), Style: Chicken
Very durable and good squeaker. However, too large and hard for my Mini Aussies to squeak. My Aussies love their squeaky toys, unfortunately not this one.
