Ceratopsian from Judith River Formation

[Troodon]

Hard to keep up to new discoveries and when I see one from the Judith River Formation from Montana even though its a year old it attracts my attention.  Material from this fauna is constantly being offered for sale and can be collected with access to ranches.  

 

 A new ceratopsid, Spiclypeus shipporum from the lower Coal Ridge Member of the Judith River Formation was described and I've attached the article for viewing.  I want to remind collectors that its not possible to know the species of teeth, horns and unguals being sold from large bodied ceratopsians.   So be careful of sellers trying to put species names to their offerings.

 

 

 

 

 

 

This figure was included in the paper and what's interesting is it shows what dinosaurs have been described from this fauna and material that as only been identified to a family level.
