Earth's Earliest Dinosaur Possibly Discovered
- A wonky beast about the size of a Labrador retriever with a long neck and lengthy tail may be the world's earliest known dinosaur, say researchers who analyzed fossilized bones discovered in Tanzania in the 1930s.
Now named Nyasasaurus parringtoni, the dinosaur would've walked a different Earth from today. It lived between 240 million and 245 million years ago when the planet's continents were still stitched together to form the landmass Pangaea. Tanzania would've been part of the southern end of Pangaea that also included Africa, South America, Antarctica and Australia.
