Most fossil collectors do have an ammonite in their
Ammonites, named after Egyptian God Ammon, the Egyptian God
of life and reproduction, As like a ram’s head.
There are many
classification of ammonites and start from the Devonian period, some 415
million years ago to 240 million years ago.
Many collectors do not realize this ammonite shell contained
squid like marine creature with a sharp Neck and long tentacles to catch small
fish and crustaceans.
The ammonite shell was so unique the animal used the air
chambers inside to rise and sink in the water and to propel itself by squirting
water .The interior chambers can be seen when specimens are sliced open
revealing internal structures to pump
and siphon air and to propel in the water at reasonable speed to catch their prey.
Canadian ammonites have good reputation due to the brilliant
effervescent rainbow colours that are formed through oxidation. They are
considered as a national treasure of Canada and are amongst the world’s most
Madagascar ammonites are formed mostly as iridescent red
fire on dark brown shell to iridescent shine on ivory base. Good specimens also
have fern pattern which are popular with collectors.
Moroccan ammonites are formed in very hard black basalt and
this makes it hard to dig out so most are cut out with electric hand tools or
in soft grey shale and these have no colour.
Indonesian ammonites are different in that the shell is
white colour with brown inclusion shell like formation.
British ammonites are formed in pyrite and very metallic appearance.
Ammonite pairs are the specimen cut into two pieces to
expose the air chambers, large specimens make ideal displays and smaller ones
do end up on females for they are re made into unique fossil earrings.
