The ichnological fossil record has previously provided key evidence for the
diversification of land vertebrates (tetrapods) during the Carboniferous
Period, following the invasion of the land. Within the UK, tetrapod
ichnofossils from the late Carboniferous of the English Midlands are well
documented, but few such fossils are known from earlier in the period. We
present a rare ichnological insight into early Carboniferous tetrapod
diversification in the United Kingdom based on a Visean-aged specimen
collected from an interdistributary trough palaeoenvironment at Hardraw
Scar, Wensleydale, North Yorkshire. This specimen represents the
stratigraphically oldest known tetrapod trackway from the UK. We refer this
specimen to Palaeosauropus sp., providing the earliest known occurrence of
an edopoid temnospondyl. Supplementing the sparse record of contemporary
body fossils from the early Carboniferous, this provides further insights
into the diversification of temnospondyl amphibians across Euramerica.

Caption blooper: "Temnospondyls, such as this Chenoprosopus milleri, are
thought to have played similar roles in the Cambrian [!!!] ecosystem as
crocodiles do today."

Carboniferous, I assume....
