Russian paleobiologists found inside a piece of Baltic amber the fossil remains of a previously unknown insect that lived in Europe approximately 30 million years ago.
It would be a specimen with certain similarities to the lacewing, but with predatory or grasping legs that made it resemble a praying mantis.
Even though mantis lacewings have been found in fossil records dating back 145 million years to the Cretaceous epoch. This is the first adult lacewing mantis fossil found in the Cainozoic geological epoch.
The researchers explained that the first Mantispidae adult from Baltic amber put it into a larger framework that addresses the quantitative morphology of raptorial forelegs throughout the lineage in terms of present and extinct variety.
In its morphology, the fossil was quite similar to the extant genus Mantispa, but a layer of white film characteristic of Baltic amber fossils makes it difficult to be certain. So they named her after Mantispa? Damzenogedanica.
The finding, according to the researchers, raises questions about how Mantispidae evolved during the last 66 million years, when the Cainozoic epoch began.
The found insect was analyzed by “a combination of techniques that include microscopy and microtomography, where X-rays are used to build a cross section and a 3D model of an organism”as revealed by the journal Science Alert.
“Here we report the first adult Mantispidae from Baltic amber and place it in a larger framework regarding the quantitative morphology of raptorial forelimbs across the lineage in terms of extant and extinct diversity,” the researchers write in their paper. .
