📖 1. Overview

Juramantis jinjuensis is a mantis-group (order Mantodea) insect fossil found in the Jinju Formation and described as a new species in a 2025 monograph on Jinju cockroaches. It is one of the insect fossils found in the Jinju Formation of Korea.

🦴 2. Anatomy & Morphology

Its forewing is about 15 mm long and about 4 mm wide with an eyespot-like pattern, and its forelegs are only moderately specialized for hunting.

🔍 3. Fossil Record & Paleoecology

Three complete specimens preserving the head, antennae, and legs were found, suggesting that they were buried nearby rather than drifting from afar. The holotype specimen is housed in the Department of Science Education at Gongju National University of Education in Chungcheongnam-do.

🇰🇷 4. Connection to Korea

It came from the Jinju Formation around Jeongchon in Jinju, Gyeongsangnam-do, and the holotype specimen is at Gongju National University of Education in Chungcheongnam-do.
