Researchers have done careful modelling of Pterosaurs, flying dinosaurs, and found that far from being cumbersone gliders, they most likely were as good fliers or better than modern birds.
Researchers, led by Lawrence Witmer from Ohio University, studied a pair of pterosaur skulls and generated three-dimensional reconstructions of their brains.
This was possible because pterosaur brains are nestled so tightly in their brain-cases that they leave a bony impression, betraying their structure.
The study revealed that the flying dinosaurs were very much like modern birds, and where they differed, they may have been even better fliers. [Secular Blasphemy]
