The national park's gritstones and shales were laid down in the middle Carboniferous Period
(around 326-316 million years ago) when the northern part of the Peak District was covered by a huge river delta flowing down from what is now the Scottish Highlands and Northern England.
The creature lived in the Upper Carboniferous period
, when many of the coal seams in Britain were formed.
The droplets, or blebs, date to the Carboniferous period
, when swampy forests of ferns and giant lycopod trees dominated the Earth.
Carbon sequestration by green plants has been with us since the carboniferous period
some 345 million years ago, not exactly a new phenomenon.

350m years ago, on the paving stones outside the World Museum; A 244myear- old coral fossil, on the bollards by the Steble Fountain
The first known orthopteran fossil dates back to the upper Carboniferous period
(~299 mya, Chopard 1920, Storozhenko 1997, Gorochov 2001), making orthopterans one of the most ancient of insect lineages.
"As well as focusing on Harry Potter, the festival will give people the chance to find out about what the Earth was like 350 million years ago in the hot, humid, Carboniferous Period
- a time of giant insects and huge amphibians."
The transformation into coal took place under these conditions, starting during the Carboniferous Period
, about 340-270 million years ago, and at high pressures, as layer upon layer built up.
Entomologists say these invertebrates (backboneless animals) were the first creatures to fly, dating from the Carboniferous period
about 360 million years ago.
Examples are for such noteworthy species as the ginkgo (Ginkgo biloba), a Chinese tree that existed during the Carboniferous Period
, or the coelacanth (Latimeria chalumnae), a fish that was thought to have disappeared during the Cretaceous Period but is today confined to the waters of the Comoros.
It has been over 100 million years since the giant coniferous forests that evolved in the Carboniferous Period
began giving ground to the upstart flower-bearing species that now dominate the world's diversity of trees.
The Permian was the end of the Carboniferous period
, which means "coal-bearing".
The UK shales were formed in the carboniferous period
over 300 million years ago, while those in the US were formed over 400 million years ago in the Devonian period.
Highlights include over 800 prehistoric fish fossils found in local coal deposits formed in the Carboniferous period
As a result of this new tectonic context, a backarc basin developed in the Frontal Cordillera, where the sedimentation of the El Plata and Cerro de Agua Negra formations took place during the Carboniferous period
(Mpodozis and Ramos, 1990; Fernandez Seveso et al., 1993; Astini, 1996; Azcuy et al., 1999; Charrier et al., 2007).
