Borogovia: Research Database
Troodontidae (Theropoda) · Late Cretaceous (~70 MYA) · Asia — Mongolia (Gobi Desert, Nemegt Formation)
Research Note: Borogovia was a troodontid theropod from the Late Cretaceous of Mongolia — a member of the Troodontidae that provides data on troodontid diversity and the evolution of bird-like features in theropods.

Active Debate: Troodontid Evolution and Cretaceous Asian Ecosystems
Whether troodontids like Borogovia occupied a distinct ecological niche from other troodontids in the Gobi is debated. The diversity of troodontids in the Late Cretaceous of Asia — and their ecological roles — is still being understood.
The evolutionary relationships between different troodontid lineages — and the selective pressures driving their bird-like features — is a major question in dinosaur paleontology.
What We Still Do Not Know About Borogovia
- Complete skeletal morphology: Partial specimens known.
- Diet: Likely carnivorous/insectivorous.
- Social behavior: No direct evidence.
- Color: Unknown.
In Depth
Borogovia is a genus of troodontid dinosaur that lived in Mongolia during the late Cretaceous. As a troodont, Borogovia would have been a predator, certainly capable of taking down smaller prey animals by itself. Also like other troodonts, Borogovia had a specialised second toe, but unlike them, the claw was not sickle shaped but flatter and shorter. It has been speculated that Borogovia may have adapted this in order to make up for inherent weaknesses stemming from the underdeveloped third toe.
