A: Scientists are still debating the issue. There are three major hypotheses:
The idea that dinosaurs may have migrated to shorelines during winter is a distinct possibility. The first seagrasses were developing during the late Cretaceous (when dinosaurs were around). And today, sheep in the Orkney Islands, off Great Britain, are known to feed on kelp. As for longer migrations (hypothesis 3), my colleagues and I feel that current evidence strongly suggests dinosaurs wouldn’t have gone that far.
