A unique event caused this individual arthropod to become fossilised from the Cambrian period over 500 million years ago. The limestone nodule containing the trilobite of the order Redlichiida, family; Saukiandidae, once found has been prepared and eventually split to reveal a beautiful and rare positive and negative impression of the once living prehistoric marine invertebrate.
The condition is one of as found, with no alterations, a fine complete rusty colour carapace impression preserved since the time it was laid down eons ago.
A brief trilobite history; The order or group of trilobites evolved during the Pre-Cambrian period approximately 550 million years ago, One of the most complex forms of early life, the trilobites reign lasted over 270 million years coming to an end around 250 million years ago in the time of the Permian period. Trilobite genus-types were diverse and globally extensive. The Trilobite was a member of the Proetida Order, Family of the Proetidae. Trilobites were complex animals, having the first compound eyes and segmented bodies which enabled them to enrol, possibly for a defence posture. The name trilobite refers to the three-part body shape, this is longitudinally referenced to the tri-lobed effect of the whole arthropod and not, as often is the case, mistaken for the three main and distinctive constituent parts of the carapace, the cephalon (head), the thorax (body) and the pygidium (tail).
