However, little is known about the early development of insects, as there are virtually no fossils from a 60 million year period between 385 and 325 million years ago. From the time before this gap so far only a few fragments were found that do not allow accurate conclusions. Paleontologists are therefore puzzled over whether the sudden biodiversity in the Devonian developed slowly during the time of the fossil gap, or whether the evolution of the insects in the middle of the carbon gave a sudden boost.
Strudiella now suggests that the development in the carbon had a long lead time. Garrouste and his colleagues discovered the fossil in a quarry in Belgium. The fossil was relatively poorly preserved, but the combination of various body features suggested that it must be an insect. As the researchers write, the animal was petrified at the bottom of a shallow sea swarming with Triops crabs. Strudiella, however, lived on land and either fed on plants or was omnivorous. Wings could not detect the researchers, but they suspect that it was the larva of a winged insect.Romain Garrouste, (Muséum national d'histoire naturelle, Paris) et al: Nature, Vol. 488, p. 82, doi: 10.1038 / nature11281 © science.de - Ute Kehse advertisement
