The fossils were found in the mine near Lightning Ridge, New South Wales, and include a new dinosaur species as well as the world’s most complete opalized dino, according to experts.
“We initially assumed it was a single skeleton, but when I started looking at some of the bones, I realised that we had four scapulae (shoulder blades) all from different sized animals,” said Dr. Phil Bell, lead researcher from the University of New England in Australia, in a statement.
The remains were discovered by opal miner Robert Foster in the 1980s and include parts of four skeletons. These include small juvenile dinosaurs and larger creatures, which may have been 16.4 feet in length.
Recent analysis has shed new light on the discoveries.
Bell said that there are about 60 opalized bones from one adult dinosaur and bones from at least three other animals.
The new dinosaur has been named Fostoria dhimbangunmal in honor of Foster. The study is published in the Journal of Vertebrate Paleontology.
Last year Bell and his colleagues named a new small plant-eating dinosaur found at the Lightning Ridge site.
In a separate project, paleontologists in the U.S. recently named a tiny 3-foot-tall relative of the Tyrannosaurus rex.
In 2017, vandals wrecked a dinosaur footprint in rock at a renowned paleontology site in Australia.
