When the matrix is carefully removed with professional tools under microscope, the fossil will keep the scars of the original fractures and the better the preparation, the least the break tracks remain. The results of this is that most of genuine fossils have normal breaks and this is a proof of authenticity, in other words! Trilobites are hard-shelled, segmented creatures that lived hundreds of millions of years ago in the Earth's ancient seas. They are considered to be one of our planet's earliest complex life-forms and are one of the key signature creatures of the Paleozoic Era. Trilobites went extinct before dinosaurs even existed.
Trilobites were the first creatures with a skeleton (Exoskeleton) so they were easily fossilized. Their shell is divided lengthwise into three lobes (hence, the name TRILOBITE meaning "three-lobed"): a central axial lobe, and two symmetrical pleural lobes that flank the axis. Morphologically, the trilobite body is divided into three major sections.
A cephalon (or head) with eyes, mouthparts and sensory organs such as antennae. A middle region called the thorax, made up of a number of overlapping segments (anywhere from 2 to 61). A pygidium (or tail section) in which the segments were fused. Please check our other auctions. Create your brand with Auctiva's.Attention Sellers - Get Templates Image Hosting, Scheduling at Auctiva.
