Stash from Singapore International Jewellery Show 2009: Ammolite Cab

Alright, this cab is not really my purchase from the show.. but rather a gift from one of the store holders there because a group of my friends were so enthusiastic in buying the stuff from his store...

This piece has a nice play of colour( as you can see in the picture taken with flash), as well as an interesting shield shape!

Will be thinking what I can do with this!

Stash from Singapore International Jewellery Show 2009:Ammonite Ear Rings

Another of my stash from the show..

A pair of ammonite ear rings, set in 925 silver!
I really like the designs on this piece, which is seldom seen in ammonites!

The colour contrast of the fossil is also pretty interesting!

Will be converting this into something interesting... stay tuned...

Sand Dollar

Another fossilized sand dollar...

Obtained this specimen from a book store in Singapore... If you look closely, you can see the floral design on the fossil, which is almost similar to the Singapore one dollar coin..

Wonder if thats the reason why its called a sand dollar!

Fossilized Sharks Teeth

A nice specimen on a fossilzed shark's tooth!

Take a closer look, you can observe that there is a lot of details preserved.. like the striations on the tooth.

Lovenia Forbesi Echinoderm

This is a Lovenia Forbesi Echinoderm probably from a Morgan Limestone, Mannum Formation. The locality is from the Murray River in South Australia

Age. Oligocene to L. Miocene

Approx. 23 million years old , now don't you feel young?

Ammolite

Another nice flashy ammonite...

This one shows iridiscence with a predominant red play of colour!
I think the thing about ammonites is that they are found in a variety of shapes and designs.. perhaps just Mother Nature's way of creation!

Stromatolite

This may resemble the micro crytalline quartz, Tiger's Eye, but in fact its a fossilzed bed of algae, known as Stromatolite.

A closer look of the specimen shows layers of different colours!

Stromatolites (from Greek στρώμα, strōma, mattress, bed, stratum, and λιθος, lithos, rock) are layered accretionary structures formed in shallow water by the trapping, binding and cementation of sedimentary grains by biofilms of microorganisms, especially cyanobacteria (commonly known as blue-green algae).

Trilobite Elrathia kingi

This is a nice collection of Tribolite Elrathia kingi. I actually recevied this set from a friend for my birthday years back.

From small to large.. the details of this fossilized trilobite specimen is very well preserved!

Trilobites ("three-lobes") are a well-known fossil group of extinct marine arthropods that form the class Trilobita. Trilobites first appear in the fossil record during the Early Cambrian period (540 million years ago) and flourished throughout the lower Paleozoic era before beginning a drawn-out decline to extinction when, during the Devonian, all trilobite orders, with the sole exception of Proetida, died out. Trilobites finally disappeared in the mass extinction at the end of the Permian about 250 million years ago.

Fossilized Crinoids

This fossilized crinoid specimen was obtained from a local book shop:

Can see millions of them fossilized, so much that it gives the entire specimen a 'marbled' look!
A close up view on the polished side reveals:

Many crinoids resemble flowers, with their cluster of waving arms atop a long stem, they are sometimes called sea lilies.

Orthoceras

Orthoceras , which means straight horn, is a genus of extinct nautiloid cephalopod.

This is a beautiful fossilized Orthoceras specimen whereby you can observe 3 different pieces of different sizes.

Fossilized Molar

What's this little weird thing?

It's actually a fossilized molar from the Oligocene Age sheep like mammal, Oreodon, Mericoidodon culbertsoni.

A clearer, close up view of the piece:

Fossilized Dinosaur Bone

Fossilized dinosaur bone..

An animal's bones and skeletal structure are made through a process called "endochondral ossification," which is one of two types of bone formation (ossification), and is the process responsible for much of the bone growth in vertebrate skeletons.

Interesting cabbing material; Fossilized Dinosaur Bone used in jewelry is a very soft material, with a hardness of only 3 on the Mohs scale.

Fossil Coral

Time has really frozen in this wonderfully fossilized coral from Indonesia that has been polished into a cabobhon shape.

You can even see the colony of corals intact upon closer inspection.

Ammonite

Another type of ammonite.

This pair is supposedly from Madagascar You can notice a slight Mother of Pearl like play of colour on the surface

A slice of mammoth ivory

While elephant ivory is not endangered to be traded under the CITES act, mammoth ivory is not on the list.

Got this sliced mammoth ivory:

You can even observe the fine criss cross lines along the cross section, indicating that its true ivory.

Fossilized Ammonites

Fossilized ammonites come in many shapes and forms!!!

This specimen comes from Somerset, England

As you can see from the close up pics, the inner area of the ammonite has been replaced by a quartz like mineral...

Fossil Fruit

This appears to be a normal hard rock at first glance..


But when part of it can be removed to reveal the interior, one realises that this could have been a fossilized fruit or nut...

Got this from a source from Indonesia...

What do you think it could be ?

Sliced Ammonite

This pair of sliced ammonite has been polished to reveal the delicately patterned internal structure within the fossil.

Beautiful history, don't you think so?

Petrified Wood Slab

My first slab of petrified wood.

Note the beautiful colours of the polished side:

The unpolished back:



Petrified wood (from the Greek root "petro" meaning "rock" or "stone", literally "wood turned into stone") is a type of fossil: it consists of fossil wood where all the organic materials have been replaced with minerals (most often a silicate, such as quartz), while retaining the original structure of the wood. The petrifaction process occurs underground, when wood becomes buried under sediment and is initially preserved due to a lack of oxygen. Mineral-rich water flowing through the sediment deposits minerals in the plant's cells and as the plant's lignin and cellulose decay away, a stone mould forms in its place. It probably takes less than 100 years for wood to petrify.
