Fossil Brownish Trilobite - Ductina vietnamica
Division Name
Class:Arthropoda
Subclass:Trilobita
Family:Phacopida
Superfamily:Phacopidae
Genus:Ductina
Scientific Name:Ductina vietnamica
Geological Time: Devonian period (~385 Million years ago)
Location : Guangxi, Hunan and Guizhou Province of China
Ductina is a genus of extinct, small to average sized, eyeless phacopid trilobite, that lived during the Devonian.
The body of Ductina is small to average (up to 5cm), 1¼ to 2 times as long as wide, blunted oval. Body without any adornment. The head (or cephalon) is 2 to 3 times as wide as it is long in the direction of the axis (or sagittally). The cephalic axis (or glabella) is strongly widening forward with shallow furrows, the front curving downward to end at an approximate straight angle to the plain of the axis. Another shallow furrow (the occipital furrow), with left and right a deep pit (apodemal pit), crosses to the back of the glabella to define a narrow band (or occipital ring), and just in front left and right a small lobe is defined by shallow furrows and a deep pits. The back of the cephalon is often broken, obscuring the features of the occipital ring. Eyes and eye ridges (palpebral lobes) are absent. The natural fracture lines (sutures) of the cephalon coincide with its margin (unique with the Phacopidae), so there are no free cheeks (or librigenae). The genal angles are rounded, not truncated, no genal spine. The thorax has 10 segments, and the width of the axis is about ? of the thorax. Tailpiece (or pygidium) is 20 to 35% of the length of the body. The pygidial axis (or rachis) is pointed (or acute), ending at the border.
This species of the genus Ductina vietnamica lived during the Devonian in South-East Asia.
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 (anyw from 2 to 61); - a pygidium (or tail section) in which the segments were fused.
