Philovenator: Research Database
Troodontidae (Theropoda) · Early Cretaceous (~120 MYA) · Asia — China (Yixian Formation, Liaoning)
Research Note: Philovenator was a troodontid theropod from the Early Cretaceous Yixian Formation of Liaoning, China. As a small paravian theropod, it provides important data on the diversity and evolutionary relationships of troodontid dinosaurs in the Early Cretaceous of Asia.

Active Debate: Troodontid Systematics and the Evolution of Bird-Like Theropods
Whether Philovenator represents a basal or derived troodontid is debated.
What We Still Do Not Know About Philovenator
- Complete skeletal morphology: Partial specimen known.
- Feather integration: Presumed based on troodontid phylogeny.
- Diet: Likely carnivorous/omnivorous.
- Social behavior: No direct evidence.
In Depth
Originally attributed as juvenile Saurornithoides mongoliensis, the partial left hind limb of this troodontid was firmly established as being of a different genus thanks to an osteohistological analysis of the bone. This revealed that the fossils were closer to Linhevenator tani, yet the team studying the remains concluded that while similar, the remains were different still to the known fossils of Linhevenator. Philovenator was then established as a new genus, with the generic name implying ‘love to hunt’, and the species name P. curriei in honour of the palaeontologist Dr Philip J. Currie.
