What was Gobihadros?
Gobihadros was a plant-eating hadrosauroid from Late Cretaceous Mongolia. It is especially useful because relatively complete skulls and skeletons provide a detailed view of a dinosaur outside the most specialised duck-billed family, Hadrosauridae.
What makes the fossil distinctive?
The teeth and jaws form an important part of the comparison with later hadrosaurids. A broader duck-billed appearance does not mean every feeding feature was already identical. Researchers examine tooth arrangement, jaw shape and limb anatomy together.
Where was it found and how was it named?
Material was collected during joint Mongolian and Japanese fieldwork, and the genus was formally named in 2019. The fossils come from the Bayan Shireh Formation. The name combines a reference to the Gobi with the hadrosauroid group.
What can we infer, and what remains uncertain?
Several specimens reduce the need to borrow missing anatomy from distant relatives. They also reveal individual variation and differences caused by growth or preservation. Gobihadros helps test ideas about how hadrosauroids diversified in Asia, but the discovery of a well-preserved animal does not establish a simple straight line of ancestry to every later duck-billed dinosaur.
Is a hadrosauroid necessarily a hadrosaurid?
No. Hadrosauroidea is the broader group; it includes close relatives outside the more specialised family Hadrosauridae.
How can you check the evidence?
The Paleobiology Database record catalogues Gobihadros under Hadrosauroidea. Its linked bibliography identifies this research starting point: K. Tsogtbaatar, D. B. Weishampel, and D. C. Evans, M. Watabe. 2019. A new hadrosauroid (Dinosauria: Ornithopoda) from the Late Cretaceous Baynshire Formation of the Gobi Desert (Mongolia). PLoS ONE 14(4):e0208480:1-47. Open the bibliographic record. A catalogue entry establishes the source trail; it does not independently verify every later illustration or behavioural claim.
Use the dated genus overview to follow the references behind the discovery and anatomy discussed above. When sources disagree, compare which specimen and rock layer each author studied. A reconstructed whole animal can combine original bones with comparisons to relatives; those two kinds of evidence should not be confused. The account above explains the particular limits that matter for Gobihadros, rather than supplying unsupported size, speed or lifespan figures.

Quick answers
- Where have Gobihadros fossils been found?
- The discoveries discussed here come from Mongolia. Modern place names describe discovery locations, not a complete ancient geographic range.
- When did Gobihadros live?
- It is placed in the Cretaceous period. See the discovery discussion for qualifications about the particular rock layers and dating.
- Where can I compare Gobihadros with related dinosaurs?
- Follow the related field notes below. Comparisons explain shared anatomy; they do not imply that all the animals lived together.
