- Phylogenetic relationships within Maniraptoria.
- Ecological role in Cretaceous ecosystems.
In Depth
The type fossils of Ostromia were originally identified as belongs to a pterosaur and then eventually a species of Archaeopteryx before finally being re-identified as a distinct genus and a kind of anchiornithine dinosaur. Ostromia would have likely been a small predator, possibly more of a hunter of insects.
