Tuesday, March 28, 2017 (TheGuardian) – Scientists find five large #Dinosaur Footprints in a #theme park of Australia. They believe the dinosaurs existed 130 million years ago, and the prints are present in a land that can be studied in the summer. The prints are approximately 1.75 meters long and originated from a giant sauropod.
Steve Salisbury, a paleontologist at the University of Queensland and the lead author of the study says, “We have discovered numerous dinosaur fossils, but these tracks are enormous.” The discovery is published today in the “Journal of Vertebrate Paleontology.”.
The color of dinosaurs
Salisbury says it is impossible to comment anything about the #Color Of Dinosaurs. They might be green, golden, brown, or red. Dinosaurs lived in different environments. It was in their interest to be colored to blend into different environments to hide from hunters. The newly discovered fossils do not predict anything about the colors of dinosaurs. Experts say dinosaurs had ears, but the soft tissues are not preserved. They probably had small-sized ears and nerve canals in their skull.
Dinosaur fossils are present in all parts of the world
The footprints reveal that dinosaurs had large, heavy bodies. It is not the first time when prints are found somewhere. Previously, researchers discovered dinosaur fossils in parts of Canada and the US. Until now, the biggest known dinosaur footprint was a 106cm track discovered in the Mongolian desert and reported last month.
When considering which animals or dinosaurs to group together, scientists look for common characteristics.
The idea is that if two animals have the same characteristic, they must have shared an ancestor. These shared characteristics are called synapomorphies. The dinosaurs that left these prints were the largest members of sauropods, a class of dinosaurs that includes creatures like the brontosaurus. Steve is excited about the discovery and believes that the next big footprints are just over a few meters. Now the challenge for paleontologists is to interpret such a wealth of footprints.
