  1. Hi, just want to share with you one of my specimens and would like some opinion with regards to the potential ID of this theropod indet. tooth from the Yixian Formation in Liaoning province. As I have little familiarity with Chinese theropods and don't see a whole lot of real specimens reference pics available unlike their Moroccan or USA counterparts. Any input or insight from experts or experienced collector would be greatly appreciated. Here is the tooth in question and it's details that I gathered: The tooth measures about 1.5" measur
  2. Hi all, I have several sauropod teeth from the Yixian Formation of Liaoning that I need help identifying. This is Tooth 1 - White Length: 44 mm Formation: Jianshangou Beds of Yixian Formation Locality: Chaomidianzi, Sihetun, Beipiao, Liaoning Province I believe this is a Dongbeititan dongi tooth as this tooth has the morphology of titanosauriform teeth, and Dongbeititan is the only titanosauriform from that locality as far as I know. The formation is based off the locality of Chaomidianzi (my source was confident of that locality

  4. My Birthday is coming up in a few days and I am looking to knock something off of my bucket list. This insect has caught my eye. It is within my budget and from a reputable seller, but unfortunately, I know little about fossilized insects, and less about ones from China. I have done some research and it seems that Dragonflies (and many other insects) are common in the given formation. From what I can tell, there is nothing suspicious about this one, but I thought I would poll the audience just in case. Dragonfly Larvae (Roughly 2in or 5cm long) Yixian Formation

    New pterosaur from the Cretaceous of China

    A new pterosaur, Luchibang xingzhe, is reported from the Early Cretaceous of China It's represented by an excellently-preserved, nearly complete juvenile skeleton. There are even patches of soft tissue! This specimen gives more insight into the anatomy and ecology of Istiodactylidae, an Early Cretaceous pterosaur family known from China and England. Here's the paper describing the specimen (full text, no paywall): https://palaeo-electronica.org/content/2020/2931-a-new-istiodactylid-pterosaur And here's a post written by one of the authors (Dave Hone), desc
