Dinosaur adventure 3d read along part 2
Their new estimate placed the dinosaur's hip height at no more than 4.6 feet (1.4 m) and the body length at about 20 feet (6 m).īut even though the new findings reveal that the dinosaur was a smaller vegetarian and not "a scary Triassic carnivore," the discovery is still significant and exciting, study co-author Hendrik Klein, a researcher with the Saurierwelt Paleontological Museum in Neumarkt, Germany, said in the statement. The authors also found that earlier interpretations of the print likely overestimated how big the toes were, because they included impressions made by the foot's dragging claws, which enlarged the footprint's overall length by as much as 35%.

Only one of the casts survived to the present, in the collection of the Queensland Museum (the whereabouts of the other is unknown), and the scientists used that cast to create a high-resolution digital 3D model of the foot. As the mine is now closed, the tracks are no longer directly accessible, the scientists wrote.

In 1964, geologists with the Queensland Museum mapped and photographed the trackway and made plaster casts of two footprints. "The coal miners removed the coal and revealed a sandstone ceiling, complete with giant 'chicken' footprints," Romilio said. Over time, sediment filled in the tracks and hardened to preserve the impressions the plants underneath then transformed into coal, and the sand covering the tracks turned to sandstone, Romilio told Live Science in an email.
Hundreds of millions of years ago, the plant-eating dinosaur squished its feet deep into a swampy surface of wet plants and silt.
