Ancient turtle discovered on Skye

The new turtle species is a missing link between land and water-based turtles The earliest turtles known to live in water have been discovered on a Scottish island.
The 164 million-year-old reptile fossils were found on a beach in southern Skye, off the UK's west coast. The new species forms a missing link between ancient terrestrial turtles and their modern, aquatic descendants.
The discovery of Eileanchelys waldmani, which translates as "the turtle from the island", is reported in the Royal Society journals. The turtles were found embedded in a block of rock at the bay of Cladach a'Ghlinne, on the Strathaird peninsula.
It contained four well-preserved turtle skeletons, and the remnants of at least two others...check out this amazing and complete article with photos @

Fossilized rare Shark found from the Jurassic period some 240 million years ago, this is the first complete fossil of a shark...
The perfectly preserved three foot long relic of a Wodnika will help palaeontologists gain a much clearer view on how the prehistoric British shark once lived.

Migaloo has become something of a celebrity
A new white humpback has been sighted off Byron Bay on the east coast of Australia.
The newcomer, which was filmed by a television news helicopter, has excited marine scientists who think it may be related to Migaloo - to date, the only known all-white humpback whale.
Migaloo is somewhat of a celebrity down under. Why? "Because as far as we know, he is globally unique," said Professor Peter Harrison from the Whale Research Centre, Southern Cross University.
It now seems that Migaloo, (whose Aboriginal name means "white fellow") might have competition.
Although predominantly white, the new whale does have some black markings near its head and tail. So who is the newcomer?
A white calf was spotted with a normal humpback mother in Byron Bay two years ago. Experts say the new whale could be the offspring of Migaloo but further tests need to be carried out.
A record number of humpbacks have been spotted off the Australian coast this year on their annual migration north to their breeding grounds.
One thing scientists do agree on is that this second white whale has never been seen in these waters before...

Instead bringing children to some gory Shark Tournament...We should educate them that we have 'Only 50 years left' for sea fish' THINK NOW before it is to late.
Educating in schools is a good start…but not the way it is conducted at the…Disgusting Montauk Shark Tournament.

'Only 50 years left' for sea fish'
By
Richard Black
Environment correspondent, BBC News website
Natural
protection
There will be virtually nothing left to fish from the
seas by the middle of the century if current trends
continue, according to a major scientific study.
Stocks have collapsed in nearly one-third of sea
fisheries, and the rate of decline is accelerating.
Writing in the journal Science, the international
team of researchers says fishery decline is closely
tied to a broader loss of marine biodiversity.
But a greater use of protected areas could safeguard
existing stocks. "The way we use the oceans is that
we hope and assume there will always be another
species to exploit after we've completely gone
through the last one," said research leader Boris
Worm, from Dalhousie University in Canada.
This
century is the last century of wild
seafood
Steve Palumbi
Should fish be off the menu?
Send us your comments "What we're highlighting is
there is a finite number of stocks; we have gone
through one-third, and we are going to get through
the rest," he told the BBC News website.
Steve Palumbi, from Stanford University in
California, one of the other scientists on the
project, added: "Unless we fundamentally change the
way we manage all the ocean species together, as
working ecosystems, then this century is the last
century of wild seafood."
Spanning
the seas
This is a vast piece of research, incorporating
scientists from many institutions in Europe and the
Americas, and drawing on four distinctly different
kinds of data.
