Why it matters:
This marks the first time such a find has been made in the Tibetan Plateau. South Africa is reported to be one of the best regions in the world for observing dinosaur fossils.
 
The big picture:
A one-centimeter fragment of a lower jaw has been determined to be part of the Zhelestidae family, a group of mammals from the Cretaceous period.
 
Key points:
	- The fossil is a tiny, one-centimeter fragment of a lower jaw.
- Ravjaa ishiii represents a new genus and species.
- The species is named in tribute to Dulduityn Danzanravjaa, a revered Buddhist monk of the 19th century.
