Reconstruction of the 'long horn' NectrideanIn a world of swampy-forests approximately 300 million years ago a vast array of life was developing. Among them was an order of amphibians known as the NECTRIDEA.

These small, 
outwardly newt like amphibians, where primarily aquatic and lived from 320-260 million years ago during the Carboniferous and Permian epochs. They typically had a short barreled trunk and small, well developed limbs, with long tails that account for nearly two-thirds of their total length. One of the most notable features in some species is the presence of long bony extensions to the skull, giving the head a boomerang appearance!

The Nectrideans are one of the 5 major groups within the Lepospondyls (Aistopoda, Adelogyrinids, Nectridea, Microsauria and Lysorophidae). This group is important in the debate on the origin of modern amphibians (frogs, salamanders an ceacilians).

Nectridean remains are found in North America, Europe and North Africa.
