Right. Note the loss of some diversity about 2 million years before the
end, which suggests another factor causing a preliminary extinction.
I thought it was 10 million years, I don't remember where I heard that,
someone please correct me if I'm wrong.
There was some loss of diversity by the early Maastrichtian.
Pachyrhinosaurus, for example, was the only centrosaurine genus left by
then. But the saurolophines and centrosaurines didn't disappear entirely
until the Lancian period, when lambeosaurs were also virtually gone.
