örsmáir

örsmáir is a genus of extinct ray-finned fish that lived during the Late Jurassic epoch. Fossils of örsmáir have been found in Europe. This genus is notable for its phylogenetic position within the teleost fish, representing an early divergence.

The anatomy of örsmáir indicates a relatively small-bodied fish, likely adapted to a specific ecological niche within its marine environment. Its skeletal structure suggests characteristics shared with both more primitive bony fish and later, more derived teleosts. Research into örsmáir has contributed to our understanding of teleost evolution during the Mesozoic Era.

Fossil discoveries have primarily focused on isolated specimens, allowing paleontologists to reconstruct its morphology and infer its evolutionary relationships. The geological context of these finds provides clues about the ancient ecosystems in which örsmáir existed. Further study of örsmáir continues to refine our knowledge of fish diversification.
