Scientists call dinosaurs' footprints precious fossils, but
regard their fossilized tail marks as marvel.
Fossilized dinosaur tail marks were discovered for the first
time in Erdos where many fossilized dinosaur footprints had been
discovered. This was a very rare event. The lengths of these marks
range from 46cm to 164cm and the widths of the fossils vary from
3cm to 15cm. The marks were clear and complete. This was the first
time such precious fossils were discovered since the fossilized
dinosaur tail marks were found in Yuechi, Sichuan Province.
Dinosaurs left tail marks when they walked or rested. They offer
rare close-ups of the dinosaurs' tails, from which we can study the
shapes of dinosaurs' tails and further explore how dinosaurs
walked.
