Some Recent Fascinating Dinosaur Discoveries

In Scotland, off the northwest coast on the isle of Skye, scientists discovered dozens of footprints; tracts there were made by dinosaurs during the middle Jurassic Period. Around 50 dinosaur footprints were found, made as stegosaurus, duck billed giants, and long necked sauropods. Paleontologist Paige DePaulo of Edinburgh University led the research. Paleontologist Steve Brusatte, of the same university, also worked on the project. (March 12, 2020).

Doctor Elsa Panciroli, who works for the National Museums of Scotand, and her team of paleontologists were searching for dinosaur fossils on the small Scottish island of Eigg. On August 26, 2020, while running on the beach to meet the rest of her team, she ran over something that she discovered to be a dinosaur bone about 50 cubic meters(19 inches) long, believed to be a stegosaurian dinosaur like the stegosaurus, and judged to be 166 million years old from the Jurassic era. The bone fossil is now in the collections of the National Museums of Scotland in Edinburgh. Previously, the only dinosaur bones in Scotland were thought to be somewhere located on the Isle of Skye

In Africa, the remains, from the Creteceous Period, of a 100 million year old flying pterosaur, with a 6 inch beak, was unearthed by scientists. Other specimens were discovered in Europe, Brazil, and China. The flying reptile had a wing span approximately 12 feet and these creatures had large broad crests sweeping up from the front of the skull. David Martill, from the University of Portsmouth’s School of the Environment, Geography, and Geosciences led the research study. (April 3, 2020).

The world’s smallest dinosaur was discovered in 2016 encased in Burmese amber and probably lived in Myanmar 100 million years ago. This species is named Oculudentavis Khaungraae, and is a bird like dinosaur. This very small di poseur is about the size of a bee Humming bird which is the smallest bird in the world that lives only in Cuba. The dinosaur “bird” species had wings, a pair of bulging eyes; similar to eyes of a lizard, and beak with approximately 30 teeth; weight of creature less than an ounce. 

The fossil was intensely examined by Lars Schmitz, Professor of Biology at the Keck Science Center, Claremont, California and by Jingmai O’Connor. Professor of the Academy of Sciences in Beijing. China. Published in “Nature”. ( March 11, 2020). 

New results conducted indicate the dinosaurs were ” not cold blooded” but ” warm blooded” animals. (Feb. 18, 2020).  These results were based on a research study in which fossilized eggshells of dinosaurs indicated the dinosaurs had warmer body temperatures than the temperatures of their surroundings. This information was revealed by the study’s lead author, Robin Dawson, scientist of geology and geophysics at the time at Yale University in a paper published in “Science Advances”. The information called clumped isotope paleothermometry, analyzes the chemistry of dinosaur egg shell fossils in regards to the order of oxygen atoms and carbon atoms within the ranges of certain applied temperatures.

From that atomic order, the temperature of the internal body of the mother dinosaur was determined. Three sets of dinosaur eggshells fossils were used whose dinosaurs displayed profound differences among each other.
