Juramaia is a fossil of an eutherian. The fossil was discovered in 2011 and contains preserved skulls, soft tissue marks and a complete set of teeth and forefoot bones, including three molars and five molars. The fossil teeth have all of the characteristics of eutherians. Hence, Juramaia sinensis was a placental mammal of the class Eutheria. Its forearm structure indicates that it was skilled at climbing trees. It lived in trees, preyed on insects and weighed approximately 15–17 grams. It lived approximately 160 million years ago (Fig. 12).
