There's a lot of tank herbivores a t Rex wouldn't generally fuck with. Wolves won't fuck with us unless desperate and most of the time if there's humans where wolves the wolves will avoid us cause we have a history of fuckinf them up. Also pure speculation but fossil evidence of such conflicts may be a coincidence of desperate times and greater possibility of fossilization during say, the early phase of a mass extimxtion
