Another Missing Link

This handsome amphibian-fish creature, ventastega, is the latest no-longer-missing link between fish and the first land-dwelling amphibians. A new fossil find in Latvia has allowed a more complete reconstruction of the creature, first unearthed in 1994:

The new remains — including most of the creature’s skull, the braincase, half of the bones in its forelimb and a quarter of its pelvic girdle — suggest that Ventastega was an evolutionary intermediate between Tiktaalik, a four-limbed fish that lived about 382 million years ago ... and subsequent tetrapods such as Acanthostega, which were capable of walking on land.

The size and proportions of the new fossils hint that Ventastega probably measured between 1 and 1.3 meters in length.
The god of the gaps just found it necessary to wedge itself into an even smaller gap.

PZ Myers has more on the science and the discovery.

Nice.
Unlike a certain Ray Comfort's "Crocoduck", this is actually promising.

Thank you for finding this little wedge of treasure.
