I don't know if this is what you're looking for but here's a whole page full of ancient dinosaur depictions of post flood dinosaurs.Not all of them. Various pairs within 'dinosaur kind', at least one pair and possibly more depending on how many baramins there were within the overall dinosaur clade. Those dinosaurs survived the flood on the Ark. Where are their footprints in the mud left by the flood? Where are their bones? Either all dinosaurs were already extinct before the flood, or some survived on the Ark. Either way you are wrong here.
