The Dinosaur Egg Fossil Site at Hwaseong Gojeongri in the Republic of Korea (which was discovered while investigating the ecological changes of the tidal mudflats that were revealed after the Sihwa Lake Seawall’s completion) is the first place in Korea where a large number of fossilized dinosaur eggs and egg nests have been found. In particular, it is Korea’s largest dinosaur egg fossil site. Additionally, because it is rare to find so many dinosaur egg fossils in one location, it was designated as the Korean Natural Monument No. 414, in recognition of its natural historic and academic value.

After the last conservation treatment, which was carried out in 2008 because the fossilized dinosaur eggs had been exposed to the ground’s surface for nine years and had been damaged by artificial damage, natural weathering, and erosion from acid rain, the fossil site’s host rock was in urgent need of conservation. Therefore, this study investigated the material properties of rocks with dinosaur eggs, evaluated its weathering and damage, and conducted various non-destructive precision diagnoses.

In addition, the exposure of fossil-bearing rock layers to the external environment accelerates damage through natural weathering due to physical, chemical, and biological factors. Therefore, in order to resist weathering, even if the fossil is directly exposed to outdoor, researching consolidation reagent and adhesives suitable for a fossil site is essential. This study carried out indoor and field application experiments on the same rock types and rocks that make up the fossil site to select the suitable consolidation reagent for actual conservation treatment. Furthermore, by evaluating suitability through field application experiments, they were used for conservation works.
