A tiny jaw from Greenland sheds light on the origin of complex teeth
Scientists have described the earliest known example of dentary bone with two rows of cusps on molars and double-rooted teeth. The new findings offer insight into mammal tooth evolution, particularly the development of double-rooted teeth.
