Unusual distorted Asteroceras obtusum display ammonite fossil (75 mm)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 piece of limestone matrix measures 150 mm (5. 9 inches) across and the fossil ammonite measures 75 mm (2. 92 inches) across. The ammonite is very well preserved and has been prepared out of the rock to reveal the whole shell including the distinctive ribbed keel. The ribs are very finely defined,

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 piece of limestone matrix measures 150 mm (5.9 inches) across and the fossil ammonite measures 75 mm (2.92 inches) across. The ammonite is very well preserved and has been prepared out of the rock to reveal the whole shell including the distinctive ribbed keel.

The ribs are very finely defined, and the colour is beautiful and very unusual for these fossils: a mottled mix of brown and grey - these are very unusual colours for this species. Part of the edge of the shell is open, showing the beautiful internal calcite crystal that have grown inside the shell.

This one is very unusual as it has a geological fault line running through the shell. this formed during the fossilisation process as the rock was pulled apart by tectonic forces. This created a gap that calcite crystals grew inside creating a vein. This adds an interesting geological story to the fossil. 

A great example of a popular species and impressive in the flesh. The fossil weighs 1465 grams and a cut flat base to allow it to stand freely on its own for display. Fossils like this make great display pieces and add a real focal interest to any shelf, not to mention being a great conversation piece!

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

LOVE THEM!!
Size: Small, Color: (001) Black / Black / Castlerock
LOVE! These socks are so comfortable! I wear a 5 in women's and a 3 in big kid shoes. The small fit me perfectly. I see where some say they run small but I can't say that was an issue for me. They are "snug" but thats what you want with a no show sock. I feel they have support vs the ones i used to buy at Walmart. They are very soft! I am actually buying more today and throwing my other ones in the trash!

So will not write down your foot
Size: Medium, Color: (001) Black / Black / Castlerock
I love these socks. They have a little bit of gel on the top of the heel for support in your tennis shoes and so your socks don’t write down. Very good quality.

Comfy and Stay Put
Size: Medium, Color: (002) Black / Black / Halo Gray
These socks are honestly great. They’re super thin and light, so once you have them on, you kind of forget they’re even there. No bulky feeling in your shoes at all. The best part is they actually stay on. I hate no-show socks that slide down after five minutes, and these don’t do that. The little grip on the heel really works, so you’re not constantly adjusting them all day. They’re breathable too, which is nice if your feet run warm. They dry fast and don’t get that gross sweaty feeling. And there’s no annoying seam on the toe, so nothing rubs or feels uncomfortable. Basically, they’re just comfy, stay put, and don’t cause problems — which is all I want from socks.

Amazing but quality changed
Size: Large, Color: (002) Black / Black / Halo Gray
Love these socks so much, been buying them for about 4 years now!! Not giving them 5 stars anymore because the quality is different and not as good, durable and thick as before.
