New species of insect 105 million years old found fossilised in amber in Teruel

It was found by historians from Oxford University's Natural History Museum and from Spain's Geo-Mining Museum in the village of San Just in Aragón's southernmost province, according to the scientific periodical Sinc.

Teruel's amber sources are turning out to be a gold mine for experts studying the Cretacean era, and the latest finding is 'key in understanding how insect claws evolved', says palaeo-biologist Enrique Peñalver from the Geo-Mining Museum.

The insect is said to be of a 'predatory' species which were 'highly specialist hunters', Peñalver reveals, although their claws did not have the complex sensory structure similar insects do today.

It was originally thought the fossilised insect was a type of European Mantis – a large haemimetabolic species in the Mantids family – but closer study appears to show it is more likely to be part of the Chrysopidae strain, known in English as 'Green Lacewings', or the Myrmeleontidae, whose common name is the 'Antlion', and is probably of the mantispid or mantidfly type, whose wings are transparent and have the appearance of being made of lace or netting.

Only five types of mantispid are known, to date, to have been found in Europe, and this is the first time a fossilised version has been discovered on the Iberian peninsula.

It is evidence that this type of insect did in fact live in that part of the planet over 100 million years ago, says Ricardo Pérez de la Fuente, also from the Geo-Mining Museum.

Now the sixth-known mantispid to be discovered in Europe, it has been named after the region where it was dug up and is now officially known as the Aragomantispa Lacerata.

It is the oldest yet to be found frozen in time in stone, and is 'another addition to the collection of extinct life forms found in Teruel amber' which will 'play a major part' in experts' 'understanding of ecology in Cretacean forests', Peñalver concludes.
