Pterosaurs went extinct around 66 million years ago, likely due to a combination of factors. The most significant factor was likely the mass extinction event caused by the impact of a large asteroid, which led to drastic changes in the Earth's climate and environment. This event would have disrupted the pterosaurs' food sources and habitats, making it difficult for them to survive. Additionally, competition with other flying reptiles and the rise of new species may have also contributed to their decline and eventual extinction. **

Pterosaurs did not have feathers because they were not closely related to birds, which are the only group of animals known to have evolved feathers.

Therefore, the lack of feathers in pterosaurs is simply due to their evolutionary history and the unique adaptations that allowed them to take to the skies. **
