Finally a transitional fossil is found between sea to land. It has been named Tiktaalik roseae at the suggestion of Canada's Nunavut Territory natives. It is a fish but shows changes that will bring about the emergence of amphibians and other land animals.

Paleontologists have discovered fossils of a species that provides the missing evolutionary link between fish and the first animals that walked out of water onto land about 375 million years ago. The newly found species, Tiktaalik roseae, has a skull, a neck, ribs, and parts of the limbs that are similar to four-legged animals known as tetrapods, as well as fishlike features such as a primitive jaw, fins, and scales.

Cool. Really, a new fossil, a new animal, brings more of a light to our history of life. The Earth has many of these and we got lucky and found one. Being found on Ellesmere Island makes me think of something, that is where they found transitional Mammoths, or Mini Mammoths as they are more commonly known as since they are much smaller versions of Mammoths that came around the end of the last Ice Age. WHat other treasure does Ellesmere Island hold?

I heard about this on the radio this morning and thought how cool to discover something like this.
Unfortunately, there is some negative thoughts coming from religious poeple who are anti-evolution. They seem to be taking issue with the claims this is a link between fish and land animals.

Hilarious how the article has a picture of a dig right next to the ocean.
"It kind of like, when on land, and died of having no respiratory organs..."


Anyway, has anyone found a good image of the fossil? Cant make anything out in the one in the article.

It was a fish, didn't live on land... Also, the Island wasn't always an island, ever hear of Pangea?

Ever hear of Continental Shift? Did you know Everest use to be underwater and the bottom of the ocean was dry land?

Antartica use to be a lush forest/jungle with frogs and lizards and dinosaurs.

So going "Gee its right next to the ocean, it must of died when it went on land." is stupid. It wasn't on land at the time, it was underwater, just like fossils of dinosaurs are found in Antartica, a place to cold now for cold blooded animals. Of course dinosaurs, some anyways, may have been warm blooded like birds.
