Certainly dinosaur fossils have been known
for a long time. In classical antiquity, Greek and Roman times, some of
these fossils that have even been illustrated and stuff were thought of as either monsters or as giants, but the first dinosaurs to be recognized
as an ancient lineage of reptiles were found in the English countryside in the
1830s when people actually, you know, found these things and they said,
that yes in fact that these are giant exticnt reptiles.
