Study Shows Strange Dinosaur-Bird Hybrid from the Ancient World
- A fully preserved fossilised skeleton of a bird that lived in what is now China about 120 million years ago, dinosaur-like head perched atop a body that resembles more modern birds, might shed light on important stages in the metamorphosis process.
- The intriguing, recently discovered fossil known as Cratonavis zhui may offer crucial insights into the development of contemporary birds.
A fully preserved fossilised skeleton of a bird that lived in what is now China about 120 million years ago, dinosaur-like head perched atop a body that resembles more modern birds, might shed light on important stages in the metamorphosis process. Some of the most extreme changes in habitat, function, and shape occurred during the transition from dinosaur to bird, which ultimately resulted in the basic avian body plan we see today.
Even now, some of those morphological changes can be noticed in how modern birds grow. The exact sequence of these modifications and the nature of the evolutionary pressures that led to the development of purely avian traits are still up for debate.
