Cretaceous Ohio

Life in Ohio during the Cretaceous period, roughly 80 million years ago. This is easily my most speculative paleoart piece yet considering no fossils from this time period are known from Ohio. Ohio's fossil record between the Permian and the Pleistocene was destroyed by the Pleistocene glaciation, so we have no knowledge of what dinosaurs, if any, lived in this state. Despite this, we can say they did live here. Ohio at the time was dry land, a few hundred miles from the Eastern shore of the Western Interior Seaway, part of the island continent of Appalachia. Compared to the Western half of North America; Laramidia, Appalachia had a much less diverse community of dinosaurs. Only a handful of states have revealed good fossils, providing evidence for a community consisting of duckbilled hadrosaurs, armored nodosaurs, tyrannosaurs(of a more basal lineage than Tyrannosaurus rex) and perhaps dromaeosaurs. Since Ohio was dry land at the time, it is reasonable to assume that dinosaurs found on the same continent could have been found there as well. Here a nodosaur stands its ground against an attacking tyrannosaur(based on Appalachiosaurus) and a herd of hadrosaurs(based on Hypsibema) watches nearby, keeping an eye on the predator. Above a Pteranodon flies towards the nearby coast after trekking inland for some unknown reason.
