A large female spider, Nephila jurassica, was described from Middle Jurassic strata of north-east China and placed in the modern genus Nephila (family Nephilidae) on the basis of many morphological similarities, but, as with many ancient fossils, the single specimen lacked synapomorphies of the family (Selden et al. It was placed in the modern genus Nephila on account of its large size and an assemblage of morphological features typical of that genus. The most interesting feature in the spider is its size: its body is exactly as long as that of the largest modern spiders or 2.5 centimetres (1 inch). [6], Mongolarachne jurassica is known only from two fossils, the holotype, specimen number "CNU-ARA-NN2010008" which is a mostly complete adult female and the later described allotopotype male, number CNU-ARA-NN2011001-1 (part) and CNU-ARA-NN20110001-2 (counterpart).
