The finding of a fossil of this species seems to close the gap between the fish Panderichthys and the tetrapod Acanthostega. This article summarises the scientific report that appeared in the journal, Nature.
Information from the BBC on the discovery of a fossil of Eucritta melanolimnetes in a limestone wall in Scotland and the ensuing discoveries in the Black Lagoon from which the stone had come.
New fossils of an ancient, four-limbed creature, Ventastega curonica, help fill in the blanks of the evolutionary transition between fish and the first land-adapted vertebrates.
