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. Pterosaurs were a group of flying reptiles that lived during the Mesozoic era, and their closest relatives were other reptiles like dinosaurs and crocodiles. While feathers are a feature that evolved in the lineage leading to birds, pterosaurs evolved a different type of skin membrane that allowed them to fly. 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. **

A diagnosis of Cerebral Microangiopathy means that there is damage to the small blood vessels in the brain, which can lead to reduced blood flow and oxygen delivery to the brain tissue. This can result in cognitive impairment, such as difficulties with memory, thinking, and reasoning. While Cerebral Microangiopathy itself does not necessarily mean you will develop dementia, it is a risk factor for conditions like vascular dementia. It is important to work closely with your healthcare provider to monitor your symptoms and develop a plan for managing any cognitive changes that may occur. **

Yes, both app testing and product testing are legitimate practices. App testing involves evaluating the functionality, usability, and performance of a mobile application to ensure it meets quality standards before it is released to the public. Product testing, on the other hand, involves assessing the quality, safety, and effectiveness of physical products before they are brought to market. Both types of testing are essential for ensuring that consumers have access to reliable and high-quality products and applications. **
