Pteranodon
Pteranodon sternbergi (Pteranodon · ゲオステルンベルギア)
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 maximum wingspan for the genus as a whole, about 7.25 m, is more than half the length of a city bus (about 12 m long) (Comparison).
- 💡 The wingspan of common individuals within the genus, about 3.5 m, is slightly shorter than the length of a passenger car (about 4.5 m) (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
Pteranodon sternbergi is a species in the large pterosaur genus Pteranodon that lived in North America during the Late Cretaceous. Because information specific to this species alone could not be confirmed separately, the description follows data for the genus as a whole.
🦴 2. Anatomy & Morphology
The genus Pteranodon had an estimated maximum wingspan of 7.25 m, with common individuals measuring about 3.5 m and large individuals exceeding 6 m. Body size specific to this species alone was not separately confirmed in the sources.
🔍 3. Fossil Record & Paleoecology
Regurgitated fish preserved in the throat area of a Pteranodon specimen indicate that it ate fish. Some bones also preserve shark bite marks.
🇰🇷 4. Connection to Korea
No direct record connecting this species to Korea has been found.
