My Jurassic Park: Hell Creek Fm : Trierarchuncus

[Troodon]

I was very happy to see that recent publication that finally described the youngest known alvarezsurid Trierarchuncus prairiensis from the Hell Creek Formation.   Material is rare but is most commonly overlooked and described as Croc or unknown theropod so knowing what to look for helps.    I'm constantly on the lookout for this material and have been for years and have been fortunate to either find it or be able to acquire it over time.   I used publications of other Alvarezsauridae like the Asian Mononykus and Canadian Albertonykus to help in the identification of my specimens.  

 

The paper is pay-walled but I included it for reference purposes.

Extremely rare associated material found in SD

Very cool! Glad to see the “Jurassic Park” posts are back . Haven’t heard of this genus before so thanks for sharing the info and your fossils.

Awesome post, very informative to have something to reference on the forum for this newly named critter. Hope I find one in the coming years.

Not paywalled... I got a black tab on the right edge that says "Full text".

I wonder why I am not paywalled.  I am not a subscriber to "Cretaceous Research"....
