Polybranchiaspidida Posted Saturday at 02:51 PM Share Posted Saturday at 02:51 PM Recently, I got a tooth from Liaoning, Yixian Formation but I have poor knowledge about this tooth. Could you please help and share your opinions. There are many famous dinosaurs such as Yutyrannus, Anchiornis and so on. This tooth is really tiny and about 8mm. The sun rises as usual.
