Brymbiformes

Brymbiformes is a proposed order of avian dinosaurs that lived during the Late Cretaceous period. The name Brymbiformes was first introduced by paleontologist Thomas Holtz in 2002. This group is characterized by a unique combination of features, including a specialized hindlimb structure and modifications to the pelvic girdle.

Fossil evidence for Brymbiformes is relatively scarce, with most of our understanding derived from a few key specimens. These fossils suggest that brymbiforms were likely small to medium-sized theropods. Their anatomical features hint at a potentially arboreal or semi-arboreal lifestyle, though direct evidence for this is lacking.

The taxonomic position of Brymbiformes within the larger avian dinosaur family tree is still debated. Some researchers consider them to be closely related to advanced maniraptorans, while others suggest a more basal position within Coelurosauria. Further discoveries of new fossils are needed to clarify their evolutionary relationships and confirm their status as a distinct order. The term Brymbiformes remains a subject of ongoing scientific discussion and research within paleontology.
