Chicago’s Archaeopteryx fossil, unusually well-preserved with soft tissues, was CT-scanned and examined under UV light, revealing detailed anatomy from snout to tail and long tertial feathers. The findings suggest this bird could fly and imply that flight evolved more than once among dinosaurs, lending fresh support to Darwin’s theory of evolution.
A nearly intact specimen dubbed the Chicago Archaeopteryx, the smallest of its kind, was recovered from Solnhofen limestone and studied with CT scanning and UV light. The preserved skull, soft tissues, and long tertial feathers reveal how this early dinosaur may have used feathers to fly, providing strong evidence that flight evolved in multiple lineages of dinosaurs and reshaping our understanding of the origin of avian flight.
A newly discovered, well-preserved Archaeopteryx fossil from Chicago provides new insights into the evolution of flight in dinosaurs, revealing soft tissues, feathers, and anatomical features that demonstrate its ability to fly, supporting the idea that flight evolved more than once in dinosaurs.
Scientists analyzing hundreds of bird specimens have discovered a set of feather rules that can predict which dinosaurs could fly, settling debates on the evolution of flight. All flying birds have 9 to 11 asymmetrical flight feathers, while flightless birds vary in the number of primary feathers. Fossil analysis suggests flight evolved once in dinosaurs, with some species losing the ability while others became modern birds. The research challenges previous claims about multiple flight evolutions in dinosaurs and highlights the importance of examining feather structure in assessing flight potential.
