In the United Kingdom, researchers from the Open University, in collaboration with the National Museum of Scotland, have discovered fossils of a previously unknown species of cockroach. In their article, the scientists detailed where the fossil was found, its condition, and its place in the cockroach evolutionary tree, writes Phys.org.
For ages, cockroaches have played a crucial role in ecosystems by aiding nutrient recycling and serving as a food source for various species of birds, mammals, and reptiles. Studies indicate that these insects have existed since the Bashkirian age, approximately 323-315 million years ago. Over time, they have continuously adapted and diversified.
The recently described fossil was first discovered in 1984 by paleontologist Mike Simms. It was preserved at the Bristol Museum and Art Gallery.
The research team employed various visualization techniques, including stereoscopic images under different lighting and ultraviolet light, as well as in both humid and dry conditions, to obtain the most detailed images possible.
These images were utilized not only for study but also for creating virtual stacks and detailed drawings of the wings to better understand the dynamics of the insect's flight.
The researchers classified the fossil as a new species belonging to the Toarcian age (about 180 million years ago). They named it Alderblattina simmsi in honor of the discoverer.
This species is distinguished by its small size and unique wing coloration, making it the second known cockroach from the Toarcian stage with such a characteristic. Scientists have classified A. simmsi within the family Rhipidoblattinidae and suggest that this finding sheds light on the evolution of wing structures in Mesozoic cockroaches.
We also discussed an experiment that confirmed the discovery by volunteers in Norway.
