Leanchoilia illecebrosa
Vendor: Lagerstätte Land
SKU Number: SQ0363201
Leanchoilia illecebrosa with great appendage preserved, from Chengjiang Biota. Early Cambrian, Qiongzhusi Section, Yu’anshan Member, Heilinpu Formation, Mafang Village, Anning, Yunnan Province, China.
The great appendages would have presumably folded backwards below the trunk while the animal was swimming, and pointed forwards when the animal was resting or feeding. The distal claws and the leg branches could have been used to dig through the superficial level of the mud and to bring particulate matter or small prey items towards the mouth. More recently, the presence of mid-gut glands, eyes, and spines along the limbs have also been interpreted as potential evidence for scavenging or predatory habits. The animal would have probably swum just above the sea bottom in search of food.
This specimen has nice preservation throughout, with good preservation of one of the great appendages and preservation of the legs.
