It is hard to imagine that flying reptiles existed millions of years ago and competed with the dinosaurs for dominance over the skies. However, the recent discovery of valuable 107-million-year-old pterosaur bones in Victoria, Australia, has provided scientists with crucial information that they had been seeking for years. These creatures were the first aerial vertebrates that ever lived, initially emerging about 230 million years ago, and they disappeared along with the dinosaurs at the end of the Cretaceous. The bones belonged to two pterosaurs that lived during the early Cretaceous period. The oldest of its kind ever found in Australia, the bones provided insight into how and where they lived and adapted to the harsh conditions of their time.
The research was led by a team of experts from Curtin University, including lead researcher and Ph.D. student Adele Pentland, and was published in the journal Historical Biology, in collaboration with Museums Victoria. Pentland commented that the findings were incredibly significant as pterosaurs were rare worldwide, and only a few remains have been discovered in high palaeolatitude locations. She continued that the discovery of these particular fossils would help scientists better understand how the mysterious flying reptiles lived and give researchers greater insight into the species’ adaptations and survival in colder climates. Pterosaurs were previously believed to be tropical creatures, and the discovery of fossils in regions of extreme latitudes like Victoria opened up new avenues of research for experts to explore.
The discovery in Victoria has yielded two new species of pterosaurs, the first ever described so far. The fossils were found in sedimentary rock near the town of Cape Otway, in Victoria province, an area that would have been within the Antarctic circle at the time of the two creatures’ lives. The identity of the pterosaur species remains unknown, but the researchers involved with the study have hypothesized that the pterosaurs probably spent months in almost complete darkness due to the area’s extreme latitudes.
Previously, four species of pterosaurs had been identified in Australia. However, the country’s pterosaur record remains sparse, as fossils are incredibly rare and challenging to locate. Therefore, the discovery of these fossils is critical for scientists seeking to learn more about the airborne creatures at high palaeolatitude locations and how they have adapted to life in colder climes.
The bones, which were discovered over thirty years ago, belong to two distinct kinds of pterosaurs, including a juvenile, the first ever reported in Australia. The partial pelvis bone of the larger creature had a wingspan of over two meters, and the smaller one was a juvenile, which meant researchers could obtain valuable information about growth, bone structure, and how the species evolved.
Although the bones provide valuable clues, there is still not enough information available to ascertain whether pterosaurs bred in polar conditions. Thus, researchers have highlighted the possibility of discovering answers to this question in future research projects. While these findings are amazing in highlighting the remarkable diversities of life on Earth, they offer unique insights into the mysterious world of flying reptiles from millions of years ago.
In conclusion, the recent discovery of pterosaur fossils in Victoria has provided valuable information to scientists about how these flying reptiles lived and adapted to their habitat. With the discovery of two new species, the researchers have more data to determine how these creatures survived in colder climes during the early Cretaceous period. Although there are still many questions that need answers, these fossils have enabled scientists to understand better these intriguing and mysterious creatures that once shared the skies with the dinosaurs.
