£892.00 GBP

A natural ammonoid the chambers clearly distinguished by calcification, Calcite minerals have grown within the shell, this occurs during the fossilisation processes. The Goniatitic zig-zag chamber alignment is also a very interesting feature of this specimen. The ammonoid having warm brown tonal colours to white calcite inclusions of the quartz mineral family. The fossil mounted in this accent presents a pleasing natural sculptural form as well as a scientifically interesting fossil ammonoid specimen.

The natural ammonoid displaying calcification within the chambers which can now be seen as the shell has been mechanically removed, a delightful and unique fossil specimen. Sediments created variegated and muted colourisation, caused by the absorption of minerals in the fossil bedding plane; this then is a type of fossil metamorphism, the limestone was once a silty seabed of limestone, from around 380 million years ago. The habitat of the cephalopods, a type of marine mollusc similar in attributes to the modern-day Nautilus.

Ammonoids are an extinct type of cephalopod. The cephalopod group include modern day octopi, squids and cuttlefish. Cephalopod named from the Greek and so aptly named, loosely translated into English as head-foot. The ammonoids range lasted from the Cambrian period around 500 million years ago up to the Cretaceous period around 65 million years ago, an immense period which led to much dimorphism between different genera.
