What Is The Complete List Of Dinosaur Species Known From Hell Creek, Including Tooth Taxons And Synonymous Species?

[Mioplosus_Lover24]

I have yet to see a conclusive list of EVERY dinosaur known from the Hell Creek Formation, I am curious if anyone has one or knows all the dinosaurs, thank you!

Here is a list from 2004.  @Troodon can provide any additional updates or corrections.

   I don't believe a current conclusive list exists or will ever.  It all depends on which paleontologist you are having a discussion with and when.   For example some believe that ontogenetic changes reduce the number of Pachycephalosaurs, Ceratopsians and Tyrannosaurids that are present in this assemblage.  Also some species that are described are controversial like Tatankaceratops.  So its fluid and contentious so one needs to keep an open mind but I've attached my view and with new discoveries those will change.

Thanks its amazing how the current landscape makes that 2004 list almost completely obsolete.  Just the last 10 years has seen so many new discoveries and named species.

Thanks, yes anything listed just a few years ago is of little value since just the last five years our understanding of the HC/Lance has changed significantly and hopefully will continue to expand with new discoveries.  This new knowledge has also created lots of controversy among paleontologists.
