Jurassic Bird Fossil Challenges Assumptions About Flight Evolution

WHO:

Phys.org - The discovery involves a remarkably well-preserved bird fossil.

WHAT:

Phys.org - The fossil is 150 million years old and challenges long-held assumptions about early bird evolution.

Reuters - The fossil has undersized wings, suggesting that not all early birds evolved toward better flight.

WHERE:

Phys.org - The fossil was discovered in Fujian province, China.

WHEN:

Phys.org - The fossil dates back to 150 million years ago.

WHY:

Phys.org - The findings indicate that evolution for early birds was not solely focused on improving flight capabilities.

HOW:

Phys.org - The fossil's remarkable preservation allows for new insights into the evolution of flight in birds.

A remarkably well-preserved bird fossil, discovered in Fujian province, China, is challenging long-held assumptions about early bird evolution. Dating back 150 million years, this fossil features undersized wings, suggesting that not all early birds evolved with a focus on improving their flight capabilities. The exceptional preservation of the fossil provides new insights into the evolutionary journey of birds.
