It was, in fact, the elbow bone of a 10-metre-long predatory dinosaur known as a neotheropod. McMenamin, a professor of geology at Mount Holyoke College in Massachusetts, estimated the Jurassic fossil to be between 145 million and 200 million years old, Newsweek reported.
Then there was the discovery of a well-preserved dinosaur “corpse,” unearthed by miners in Canada. While excavating at the Suncor Millennium Mine in Alberta in 2011, they stumbled upon the fossilised remains of a Nodosaurus, a heavily armoured creature dating to about 110 million years ago, according to National Geographic.
Displayed for the first time in 2017, it is considered one of the best-preserved dinosaur fossils ever found. So complete are the remains that scientists at the Royal Tyrrell Museum in Alberta were able to examine the contents of its stomach, including twigs, leaves, mosses, pollen and spores.
Last year, archaeologist Marie Woods was looking for clams on the beach in Yorkshire, England, when she spotted something unusual: the 165-million-year-old footprint of a species of theropod. A dinosaur similar to a Tyrannosaurus rex, this ancient reptile also stood on two legs and was carnivorous. It was the largest footprint of its kind ever found in that part of England, reported the Good News Network.
“All I wanted to do was grab some shellfish for my dinner and I ended up stumbling across this,” Woods told the website.
In 2011, palaeontologists in China encountered a big rock with a fish fossil on the surface. They hauled it back to the lab, where it sat for about a year, according to New Scientist. Then the researchers decided to crack it open.
To their amazement, they discovered inside the remains of a mother ichthyosaur – a fishlike creature that swam in the oceans during the Mesozoic Era 252 million to 66 million years ago – giving birth to three babies. One was already out of the womb, another was halfway out, and the third was waiting for its chance.
This fossil find altered the view of when dinosaurs began having live births, pushing back the historical record by nearly 250 million years. Ichthyosaurs, which evolved from land-based creatures, proved that dinosaurs had moved on from egg-laying much earlier than previously believed.
“This land-style of giving birth is only possible if they inherited it from their land ancestors,” one of the researchers told Live Science. “They wouldn’t do it if live birth evolved in water.”
Back at the restaurant in Sichuan province, Xing and her team continue to study the accidental discovery of the dinosaur tracks. The area where the sauropod footprints were noticed has been roped off so curious diners won’t accidentally harm them.
At first, the restaurant owner was anxious that news of the primordial find would impact her business serving homestyle meals based on local cuisine. However, she has since embraced the media hype.
“She was initially concerned that she would attract a lot of curious people and affect the restaurant’s traditional customers,” Xing wrote. “But now she understands the change and is ready to roll out some dinosaur track-themed treats.”
