Peter Dodson had a nice way of saying it; it sent something like this:
"Although you might see a Model T driving down the street, nobody would claim that the car is a meaningful part of the current automotive ecosystem."

Greetings,
No one seriously considered that every last non-avian dinosaur died in the same exact day as the impact, so we've always expected some survivorship into the earliest part of the Paleocene.
Good day,
if I understand it correctly, given the fantastic finds in Tanis locality, we can now assume that non-avian dinosaurs were still living at the time of Chicxulub impact and hence there were definitely paleocene dinosaurs. Their demise was relatively fast, but still there were surely living non-avian dinosaur in the days, weeks and perhaps months or years after the impact. So "paleocene (non-avian) dinosaurs" is now a proven fact, isnÂt it? Thank you for your thoughts, Tom
