Geological Period: Devonian · Rock Type: Siltstone
Description
Area, 0.2 ha. 0.5 ac. Description In the 1930’s a siltstone lens here yielded complete, articulated specimens of many species of early Devonian fossil 'fish'. Other disarticulated material was collected from the related sandstones. Wayne Herbert is the type locality for five species. These creatures lived in rivers and their remains have almost always been preserved as separate plates and fragments laid down during deposition in an actively flowing river. It is highly unusual to find them in a complete state resulting from preservation in a dried up, ephemeral pool. This provides us with a sample of fish preserved en masse, showing growth stages and predator prey relationships. An acanthodian contains a cephalaspid within it. The acanthodians are the earliest known complete specimens of their kind. A piece of a thelodont is one of only four specimens of articulated thelodont in Britain although they have been found elsewhere, in Canada and the Russia. Pteraspids, found here form the basis of all reconstructions of pteraspids and also other heterostracans. These specimens have added greatly to our ability to interpret the morphology of these early 'fish', which are found normally as disarticulated plates, scales and spines. This is a key site for the study offossil vertebrates.
