Trekullidae

Trekullidae is a proposed family of extinct birds. The taxonomic status and validity of this family are debated among paleontologists. The primary fossils attributed to Trekullidae were discovered in the early 20th century, with significant finds made in Europe.

The proposed members of Trekullidae are characterized by certain skeletal features, particularly in their limb bones and skull. These characteristics have led some researchers to suggest a distinct evolutionary lineage separate from other known avian groups. However, the limited nature of the fossil record and the fragmentary preservation of many specimens have made definitive classification challenging.

Alternative interpretations of the Trekullidae fossils suggest that they may represent individuals belonging to already established bird families, possibly juvenile specimens or variations within existing species. The lack of a comprehensive set of diagnostic traits that are consistently present across all proposed members further complicates their classification.

Further discoveries of more complete specimens and detailed comparative anatomical studies are needed to resolve the taxonomic uncertainty surrounding Trekullidae. Until then, its status as a distinct family remains hypothetical and subject to ongoing scientific discussion and revision.
