Earliest and most primitive pterodactyloid discovered - Science Now 23

The video covers several scientific advancements and discoveries. It begins with a discussion on a new microfluidic device developed by the University of Washington for early pancreatic cancer diagnosis. The next section explores how cougars' diverse diet allowed them to survive the Pleistocene extinction, unlike other large cats. The video then highlights the discovery of the earliest pterodactyloid fossil in China, providing insights into pterosaur evolution. Finally, it showcases the USA Science and Engineering Festival, emphasizing hands-on STEM learning.
