Remember that Ceratopsian to which we used to call Pachyrhinosaurus? You know, that ceratopsian which looked like Sinoceratops, but isn’t? Well, I found out this thread which says otherwise.

There’s a source for this.

Now, what the source said was that the Ceratopsian in the trailer was no longer called a Pachyrhinosaurus, but they didn’t name it. However, Chris Pugh confirmed that before this confirmation source, the ceratopsian was originally a Pachyrhinosaurus before having its name changed to Sinoceratops sometime after the first trailer. This would say that to avoid anger from fans, they changed the species. I vehemently, but politely, disagree with the choice, as there are images that show that the ceratopsian is more of a Pachyrhinosaurus than a Sinoceratops.
I found on the DPG website that in the Inactive Dinosaurs/DNA Samples that Pachyrhinosaurus was one of the inactive cloned dinosaurs.
I will edit this later.
