摘要

It's ok, it's trapped. This exotic, praying-mantis-like cockroach that lived at the same time as dinosaurs was caught in amber about 100 million years ago. It is part of a newly discovered family of extinct predatory cockroaches. Peter Vrsansky, of the Geological Institute in Bratislava, Slovakia, and Guenter Bechly, of the State Museum of Natural History in Stuttgart, Germany, say its long neck - which allowed the head to rotate freely -and unusually long legs suggest it pursued prey (Ceologica Carpathica, DOI: 10.1515/geoca-2015-0015). The fossilised insect, called Manipulator modificaputis. was discovered at a mine in Noije Bum, Burma. During the Cretaceous period when it lived, several predatory cockroach-like lineages evolved. Only one group survives today: praying mantises. The specimen is one of dozens of preserved insects found in the area, making it the most important site of dinosaur-era amber, says Vrsansky. Many pieces of amber contain complete adult insects, and they should help reconstruct the history of the animals and their ecosystem.
