The Great Dinosaur Herds of the Middle East

Some of the most compelling evidence that dinosaurs traveled in large herds has just been uncovered in the Republic of Yemen. Researchers found tons of dinosaur tracks, unearthed by a local journalist, which show the footprints (pictured) of both two-legged and four-legged dinosaurs roving in large groups in the Arabian Peninsula. This was before the Red Sea had formed, so the dinos probably just tromped there from Africa. [First Dinosaur Tracks in the Arabian Peninsula via PLoS One]
