A fossil spider from the Cretaceous of Korea

A fossil spider from the Cretaceous Jinju Formation of Korea is redescribed as Korearachne jinju, n. gen. n. sp. Previous description of this specimen, the only known fossil spider from Korea, was inadequate, and here we present a more detailed interpretation and illustration of the specimen. The fossil spider is preserved alongside juvenile albuiform fish, Diptera and possible crustaceans, which suggests a mass mortality event. Familial identification of the spider is impossible, but it probably belongs to a guild of wandering spiders, possibly lycosoids.
