In this week the fossil hominin I would like to talk about is one human tooth and two piece of cranium which can be connected together. All this three fossil were founded in the hualong cave in east anhui province China.
There are also many fossil of animal in hualong cave most of them are Bos and Cervus, Stegodon, Rhinocerotidae, Tapirus, Ursus and other small carnivores are also have been founded in the cave. According to this fossil paleoanthropologists find the age of the cave was in the middle of the pleistocene, which means the date of the fossil is around 780-130ka.
The tooth has been perfectly saved, from endodontium to the top of the tooth. Their is nothing broke on the tooth except an tine enamel deficiency. Wear marks can be seen on the surface of each tooth tip, however, it is estimated that this tooth is a young individual based on the relatively light wear of the occlusal surface. The size of the crowns was significantly larger than that of early modern humans, modern humans and European middle pleistocene humans, and located in the variation range of homo erectus.
As for the craniums, both pieces of bone are pale yellow, deep petrified, thick, smooth and rich in nourishing holes. And two bones can perfectly connected together. At the back of the fragment, there were 44mm long coronal sutures, which were very clear and showed no signs of healing, which can also be deemed to a young individual. The skull also has a small frontal curvature, a thick temporal line and thick bone walls. In addition, the frontal bone also has the structure of the middle frontal suture and enlarged frontal sinus.
Combined with the morphological characteristics revealed by the comparison of human frontal bones and teeth in hualong cave, the human fossils found in hualong cave may represent homo erectus living in the middle pleistocene.
