Koreanaornis
Koreanaornis hamanensis (Koreanaornis · Koreanaornis)
Known only from fossils. The IUCN Red List assesses only species extant since 1500 CE, so fossil taxa are not assigned a category.
💡 Everyday Comparisons for Size, Mass & Speed
- 💡 The longest third toe impression, at about 2.5 cm, is similar to the diameter of a Korean 500-won coin (about 2.65 cm) (Comparison).
- 💡 Because the trackmaker is estimated to have been about the size of a modern pigeon, it can be compared to a pigeon seen in a park (Comparison).
Reference standards: coach bus ~12 m, mid-size car ~4.9 m, compact car ~1 t, basketball hoop 3.05 m, credit card 8.56 cm.
📖 1. Overview
Koreanaornis hamanensis is an avian ichnotaxon known from footprints rather than body fossils, and is a Korean bird footprint first named from Yongsan-ri, Haman, Gyeongsangnam-do.
🦴 2. Anatomy & Morphology
Three toes point forward without webbing, and the first toe (hind toe) left no impression. The second and fourth toe impressions measure about 1.8 cm, and the third measures about 2.5 cm.
🔍 3. Fossil Record & Paleoecology
Its size is estimated to have been about that of a modern pigeon. In the same Haman Formation, pecking or probing marks made by bird beaks were reported for the first time alongside the bird footprints.
🇰🇷 4. Connection to Korea
The bird footprint fossil site of the Haman Formation in Yongsan-ri, Haman, Gyeongsangnam-do, was discovered in 1969 by teacher Heo Chan-gu, named by Professor Kim Bong-kyun of Seoul National University, and designated as Natural Monument No. 222 (Korea) in 1970.
