The World's Oldest dinosaur named Nyasasaurus

Nyasasaurus parringtoni , claimed to be the oldest dinosaur that lived about 240 million years ago . Nyasasaurus fossil was discovered in Tanzania , Africa in the 1930s but scientists have examined in detail the lately .

Nyasasaurus crowned as the oldest dinosaur because scientists estimate the age of ten to 15 years earlier than the previous oldest dinosaur fossils 230 million years old . The oldest dinosaur previously found in South America , with the characteristics of small size , light bodied , and eat meat .

Other research team members , Sarah Werning from the University of California , Berkeley , USA , revealed the discovery of dinosaurs in Africa supports the idea that during this says that the dinosaurs are from the south or the supercontinent known as Pangaea .
" Right now , all continents of the South , including Africa and South America , a place where the earliest dinosaurs are found , it's all interconnected , " Werning said .
Scientists claim to have very little fossil information about Nyasasaurus . They estimated that this animal has a length of two to three meters , has been covering the tail . However, because the skull bones have not been found, it is difficult to identify ilmuwann diet or even with what Nyasasaurus running . Able to use two or four legs .
Peak arm that extends along the upper arm bone , a key feature scientists to identify and conclude if the animal does have similarities with dinosaurs . " It's called deltopectoral crest , which hold the shoulder muscles to the upper arm bone . All dinosaurs have elongated peak like this, " said lead researcher Sterling Nesbitt , a paleontologist at the University of Washington .
At least the information is obtained , making the scientists can not explain clearly whether Nyasasaurus a dinosaur or only the closest relatives of dinosaurs . Clearly , fossil Nyasasaurus very closely related to a group of reptiles such as silesaurids , which for millions of years before dominating the earth .
" That's important because it shows that dinosaurs are not really anything special when they first appeared . They may be rare and they do not diversify as soon as they arise , " said Nesbitt .
