I started writing dinosaurs of Alaska and I wanted to add a scene where a herd of Edmontosaurus cross a river and are attacked by tylosauruses but I'm not sure when the tylosaurus lived and went extinct
Went extinct during K-PG extinction if I recall correctly.
Until early Maastrichtian, we don't know if T. bernardi made it to the KPG
I'm taking about T.progier
Late campanian
Darn it
Eh, I willing to have it 3 million years later
What do you think?
