KYLINXIA ZHANGI (Syllabus: GS Paper 3 – Env & Eco)

Context: Researchers from the University of Leicester and the Yunnan Key Laboratory for Palaeobiology employed advanced scanning technology to recreate a ‘fossil monster’ that lived half a billion years ago.

Kylinxia zhangi

• Kylinxia, an extinct arthropod, inhabited the early Cambrian period, approximately 520 million years ago. 
• The fossil of this species was discovered near Chengjiang, located in the Yunan Province of southern China.
• Kylinxia is one of the approximately 250 exceptionally well-preserved fossilized animals documented in the area, collectively referred to as the Cambrian Chengjiang biota.

Key Features of Kylinxia

• It possessed a segmented body consisting of a head, thorax, and abdomen.
• Kylinxia had three eyes on its head and a pair of formidable claws, likely employed for hunting purposes.
• The creature exhibited a fused head shield, a segmented trunk, and legs with joints.
• Its head comprised six segments, reminiscent of the structure found in modern insects.

What Are Arthropods?

• Arthropods are invertebrate organisms characterized by jointed legs. They constitute approximately 75% of all known animal species on Earth.
• Arthropods are highly adaptable and can thrive in diverse habitats, ranging from the depths of deep-sea hydrothermal vents to the highest mountain regions.
