An epoch is a geological age and not a specific time span. So “65-145 Mya” (million years ago) would be the appropriate label. I can’t seem to find a label for “million years” (other than megaannum, which is just an SI prefix for years, but I don’t think Ive ever heard that used?)

You’re right — the first result I stumbled upon was the Simple wikipedia result which erroneously calls an epoch 1,000,000 years ( simple wiki link ).
Megaanum was also a common side effect of rear encounters with legendary adult performer John Holmes
