Dinosaur discoveries.

It seems everyday something new about dinosaurs are being discovered. Those thing include, but are not limited to, the parental care by looking at fossilized nests, dinosaurs having feathers determined by different old to newly discovered fossils, and now that terrestrial dinosaurs could and did swim.

Claw marks on a 100-million-year-old riverbed in China suggest that there were plenty of dinosaurs using the method of swimming to get from point A to point B. The markings show a coordinated left-right, left-right swimming style which stretch over 50 meters. The scientist studying this remarkable discovery have hypothesized that it is a carnivorous theropod which stood three feet at the hip.

The area in which these marks were found is a dried up river in China's Szechuan Province. This area contains numerous footprints from other Cretaceous era theropods and long-necked, four-legged sauropods. No wonder people consider this the "dinosaur superhighway."

It is very interesting to learn these are not the first swimming tracks discovered and there are always new things to discover about dinosaurs. The sad part is knowing that there are characteristics and behaviors that will never be discovered or 100% finalized because it is a time long lost and we do not have the technology to go back and live in that era.
