Rainbow iridescent Caloceras display ammonite fossil 70 mmA stunning example of an iridescent ammonite fossil of the species Caloceras johnstoni from North Somerset, UK. The matrix measures 95 mm (3. 8 inches) across and contains a single partial ammonite that measures 70 mm (2. 8 inches). The ammonite is well preserved as a half and has been prepared out of the rock to reveal the shell, which displays some stunningly bright iridescence that changes as the viewing angle changes, with green, red, and orange

A stunning example of an iridescent ammonite fossil of the species Caloceras johnstoni from North Somerset, UK.

The matrix measures 95 mm (3.8 inches) across and contains a single partial ammonite that measures 70 mm (2.8 inches). 

The ammonite is well preserved as a half and has been prepared out of the rock to reveal the shell, which displays some stunningly bright iridescence that changes as the viewing angle changes, with green, red, and orange colours dominating. This is about as colourful as these ammonites get! There is also a smaller partial ammonite in the matrix with a nice green colour.

The shell sits in the original thin piece of limestone shale matrix in which it was found that has been shaped and has a cut-flat base that allows it to stand by itself for display. The whole piece weighs 252 grams. 

These fossils are highly sought after and very hard to find. They are preserved in the same way as the famous Canadian "Ammolite" ammonites that are turned into valuable gemstones. These fossils make great unusual gifts and each one is totally unique.

Around 200 million years old (Hettangian, Early Jurassic), this fossil would make a wonderful addition to any collection.

Good value, soft and comfortable
Color: Black, Army Green, Light Gray, Size: 4X-Large, Color: Black, Army Green, Light Gray, Size: 4X-Large
Initial thoughts are very positive with this 3 pack shirt set. The green is similar to an OD military green and the black and gray are standard color shades. Material is soft and sizes are true to size. The mock turtleneck isn’t too tight but may still be a little annoying to some people. I do question the amount of spandex in these shirts. Tag says 5% but these shirts are extremely stretchy and feels like a higher spandex content. It’s also a little tough to figure out which way is the front of the shirt. Visually rhe front does have a lower collar line than the back but would still be nice to have a brand tag printed in the back of the shirt for quicker identification. Overall for roughly $12 a shirt these are a good choice for everyday wear. I will update rating if these shirts fail to meet expectations after further use.

Just what I wanted.
Color: Black, Navy Blue, Wine Red, Size: 5X-Large
These may have just become my standard shirt to wear. Feels good whether tucked or out. Drapes well and fits well. So far, I can see it adjust to the different undershirt I may wear. Will probably order another set in other colors and a back up set of the basics because they will get worn a lot.

Its alright
Color: Black, Size: 5X-Large
True to size per the size chart. The fabric is soft but it it feels cheap to me. It attracts lint but you can brush it off easily so its not the cheapest material I've dealt with. Also, it is opaque (not see through). There is no front/ back indicator either which is indicative of a cheap shirt in my opinion. Would be friendly for tag sensitive people (to stay positive).
