The Arctic field expedition to East Greenland, which can be followed through this blogg, includes a diverse expertise of vertebrate palaeontologist from Uppsala University that aim to tackle the evolutionary problem of the adaptation of tetrapods for life on land, and their subsequent return to the water, which represent two of the most iconic eco-morphological transitions evident in the fossil record.
The focus of this field work is the famously fossiliferous Devonian-Carboniferous (360-358 MY) and Permian-Triassic (254-252 MY) rock strata of East Greenland, which preserve the most diverse early aquatic tetrapod assemblages alongside marine sequences that could potentially yield the oldest specialised marine amniotes.
